AI video production: prompts, pipelines and programmatic rendering

Video Prompting

122 stars on GitHub6 commands
A skill for prompt engineering specialized in AI video generation. Its core job is turning a creative idea into precise technical instructions the video models can execute well. Every video generation model (Sora, Veo 3, LTX-2, Seedance, Wan 2.2, Ovi) has its own syntax, length limits and technical vocabulary — the skill knows those differences and adapts the prompt on its own. On top of that, it addresses the hardest part of AI production: character consistency across scenes, through a system of character sheets and identity sheets that act as a visual reference for the whole project.

The full flow: Character sheet → Scene reference frame → Final video prompt

  • Seedance 2.0
  • Sora / Veo 3.1
  • LTX-2 / LTX-2.3
  • Wan 2.2 / Ovi
  • Character Sheets
  • Identity Sheets
  • Image-to-Video
  • Scene Handoff Pipeline

Claude Code Video Toolkit

1,8 mil stars on GitHub12 commands
A complete suite for programmatic video production inside Claude Code. The point is to put Claude in the role of technical producer, orchestrating 10+ specialized tools in one coherent flow — from script to rendered video. It brings together visual composition with Remotion (React), voice generation with ElevenLabs, soundtracks with ACEStep, image generation and editing with Qwen, AI-generated video with LTX-2, processing with FFmpeg/MoviePy and GPU execution in the cloud through Modal or RunPod. You make the creative decisions while Claude runs the whole technical production.

The standard flow: /setup → /video → /scene-review → /design → /generate-voiceover → final render

  • Remotion (React Video)
  • ElevenLabs TTS
  • FFmpeg / MoviePy
  • LTX-2 Video Gen
  • ACEStep Music Gen
  • Qwen Image Editing
  • RunPod / Modal GPU
  • Playwright Recording

HyperFrames

Tool36,1 mil stars on GitHub9 commands
HeyGen's open-source framework, which turns HTML, CSS and animation into deterministic MP4 video — the motto is "Write HTML. Render video. Built for agents." The core idea: if the agent already knows HTML and CSS, it can produce video too. Every composition is an HTML file with timing attributes and tracks, rendered with Headless Chrome + FFmpeg; the same input always produces the same video, which makes the pipeline dependable for CI and review. It supports the main animation libraries (GSAP, Lottie, Three.js, Anime.js, CSS/WAAPI), offers a browser preview with automatic reload, local or distributed rendering through AWS Lambda, and a bundle of 21 ready-made skills for agents — from a product launch video to a pull request changelog.

The standard flow: npx hyperframes init → compose scenes in HTML with data attributes → preview with hot reload → final MP4 render

  • HTML → deterministic MP4
  • Headless Chrome + FFmpeg
  • GSAP / Lottie / Three.js
  • Preview with hot reload
  • Local or AWS Lambda render
  • 21 skills for agents
  • Component catalog
  • Figma integration

video-shotcraft

6,9 mil stars on GitHub9 commands
It turns the agent into a motion studio: 152 shot recipe cards, 209 motion previews and a complete template, all in Remotion. The recipe card is the heart of it, and it is what betrays real production experience — it carries purpose, energy, suggested duration, parameters, implementation notes and the known pitfalls. The 48 newest cards were distilled from 209 candidate motions after eight rounds of frame-by-frame review against reference footage. Sound gets the same care: 149 effects across 16 scene categories, with a rule that saves hours — pick the category first, the timbre second. And here is something rare in a README: the headless rendering section documents three concrete walls with the fix for each, instead of pretending it just works on any machine.

The pipeline: page capture → visual direction → storyboard → shot implementation → beat sync → sound design → final QA

  • 152 recipe cards
  • 209 previews
  • Remotion
  • Validated template
  • 149 sound effects
  • 2.5D camera
  • CapCut export

Install by handing over the linkThe most direct route

The agent clones the repo and links it into your skills directory itself. You can also use npx skills add Vincentwei1021/video-shotcraft or create the symlink by hand.

Install this skill for me: https://github.com/Vincentwei1021/video-shotcraft
See the motions before you askThe gallery is the interface

209 previews with search and filters, and the card name to copy. Picking the shot in the gallery before you start saves the round trip of describing motion in words.

Use the ready-made templateInk Press, 36 seconds

A validated template: 1920×1080 at 30fps, ten shots in a paper-ink-amber look, with a 2.5D camera over a real page, title cards, transitions and a pinned sound pass. The agent swaps in your captures, copy and branding.

Use video-shotcraft to make a promo for my product with the Ink Press template.
Ask for shots by nameWhen you already know what you want

The cards sit in ten functional categories. With no card specified, the skill introduces the built-in template first and asks whether you want it.

Use the deck-deal-flyin and row-embed shot cards to present this feature.
Start from a referenceInspired by, not identical to

Each card has a TSX implementation carrying the real easing and timing parameters, deterministic and driven by normalized progress — so you can adapt it without breaking the motion.

Creative Director

104 stars on GitHub6 commands
A skill that reproduces the creative process of the world's biggest agencies (Droga5, Wieden+Kennedy, Mother) inside Claude. The point is not to generate random ideas — it is to run a structured five-phase process: brief extraction, consumer insight mining with 7 techniques, ideation with 20+ creative methodologies (SIT, SCAMPER, TRIZ, bisociation), evaluation against 6 weighted criteria calibrated on Cannes and D&AD, and recursive refinement until the concept scores 9 or above. It carries anti-inflation safeguards so mediocre concepts do not collect high marks, plus two further scoring systems: the HumanKind scale (from destructive to world-changing) and the Grey scale (from toxic to best-in-world).

The full flow: "Campaign for [brand]…" automatically triggers the five phases — INTAKE → INSIGHT → IDEATION → EVALUATION → DELIVERY

  • 20+ creative methodologies
  • SIT, SCAMPER, TRIZ
  • Cannes / D&AD score
  • HumanKind + Grey Scale

Stop Slop

14 mil stars on GitHub5 commands
A skill that teaches Claude to spot and remove the characteristic patterns of AI-generated text — what people call "AI slop". The point is to make the writing sound human by stripping out the models' predictable tics. It detects banned phrases (throat-clearing openers, emphasis crutches, corporate jargon, vague claims and meta-commentary), structural clichés (binary contrasts of the "it is not X, it is Y" kind, negative lists, dramatic fragmentation, false agency and the passive voice) and applies sentence-level rules (limits on openings with interrogative pronouns, em dashes, fragments and lazy superlatives; active voice required). It includes a scoring system across 5 dimensions (1-10 each) — directness, rhythm variation, trust in the reader, authenticity and human voice, and density — where anything under 35/50 signals that a revision is needed. The repository ships the SKILL.md plus reference files (phrases.md, structures.md and examples.md with before/after transformations).

The flow: paste the text → "rewrite without AI slop" → Claude applies the rules and returns a clean version plus the score across the 5 dimensions

  • Banned phrases
  • Structural clichés
  • Active voice required
  • Score across 5 dimensions
  • 35/50 threshold
  • Before/after examples

Humanizer

30,2 mil stars on GitHub6 commands
A portable skill (a single SKILL.md in plain markdown) that strips the signs of AI writing out of any text, built by Siqi Chen. The basis is rigorous: the 33 documented patterns come from Wikipedia's "Signs of AI writing" guide, maintained by WikiProject AI Cleanup from thousands of observed AI texts. The patterns fall into 5 groups: content (importance inflation, name-dropping, promotional language, vague attribution), language (typical AI vocabulary, negative parallelism, the rule of three, synonym cycling, false ranges, the passive voice), style (too many em dashes and bold, lists with inline headers, emoji, rhetorical openings, manufactured punchlines), communication (chatbot artifacts, cutoff disclaimers, a sycophantic tone) and filler (padding phrases, excessive hedging, generic conclusions). What sets it apart is voice calibration: feed it samples of your own writing and the rewrites come back in your voice, rather than a generic human one.

The flow: install → /humanizer plus the pasted text (optionally with 2-3 of your own paragraphs to calibrate the voice) → text rewritten without the 33 AI patterns

  • 33 documented patterns
  • Based on Wikipedia AI Cleanup
  • 5 pattern groups

Humanizer PT-BR

29 stars on GitHub5 commands
A skill that removes the marks of AI writing in Brazilian Portuguese — the local counterpart to Humanizer. Detectors calibrated for English let the typical tics of models writing in pt-BR slip through; this skill covers 25+ patterns specific to the language: connectives and filler phrases in excess, a promotional or mechanical tone, formulaic sections of the "challenges and future perspectives" kind, overuse of dashes, bold and emoji, artificial dramatic hooks, vague attribution, and the predictable AI vocabulary in Portuguese. The rewrite keeps the meaning and returns text that reads naturally. One portable SKILL.md, MIT licensed.

Banana Claude

1 mil stars on GitHub8 commands
Create, edit, compare and review Gemini images from inside Claude Code — but what deserves attention is how it handles the fact that image generation costs money. The plugin installs disabled on purpose. Before any billed request it shows the prompt, the model, the data settings, the output destination and an estimate; one approval authorizes one attempt, and a changed plan needs a fresh approval. The API key stays out of commands, request URLs, metadata and CI. Cost records stay private and omit the raw prompt by default. And the README refuses the easy promise: Gemini output is probabilistic, so consistency, spelling, geometry, policy acceptance and rights clearance remain review conditions, not marketing claims.

The cycle: ask → plan offline → review prompt, privacy and cost → approve one attempt → generate → check the actual pixels

The edit path is built to make one clear change while preserving identity, geometry and brand detail — the opposite of regenerating and hoping.

/banana-claude:banana edit this cover, change only the headline color
Compare routesUp to three prompts, three models

A bounded portfolio, so you choose on evidence rather than instinct. The routes run across Nano Banana 2 Lite, Nano Banana 2 and Nano Banana Pro.

/banana-claude:banana compare these three prompts across the model routes
Review what came outThe pixels, not the promise

Checks copy, crop, composition, consistency, artifacts, rights and provenance. The project is explicit: generated output is never treated as automatically correct or production ready.

/banana-claude:banana review the generated image
Typeset exact copyLocally, no dice roll

When the wording has to be exact, the copy, fonts, logos and art are composited locally rather than trusted to the model — which misspells by nature.

/banana-claude:banana typeset the approved headline on this image
Upgrade from an older versionDo not overwrite in place

An old public install may have left an unpinned third-party MCP entry, a raw Google key in settings, or an obsolete directory. v3 ships a scan and cleanup — and rotate any key that sat on disk or in shell history.

Awesome Design MD

102,9 mil stars on GitHub4 commands
A library of design systems in plain text — more than 73 DESIGN.md files extracted from leading brands (AI platforms, dev tools, fintech, e-commerce, automotive and media). It closes a concrete gap: AI agents generate interfaces with no consistent design direction. Instead of exporting from Figma or assembling a complex JSON, you hand over a DESIGN.md — a markdown document with the color palette, typography rules, component styling, layout principles and elevation system — and the agent reads those rules to generate UI that matches the brand's visual language. Each folder ships the DESIGN.md, preview catalogs (preview.html / preview-dark.html) and prompts ready to paste into the agent. It follows Google Stitch's DESIGN.md specification.

The flow: copy a brand's DESIGN.md to the project root → "build a page with this look" → the agent generates the UI following the rules

  • 73+ DESIGN.md files
  • Palette + typography
  • Components + elevation
  • Google Stitch format
  • Light / dark preview
  • Ready for AI agents
  • Fintech / E-commerce / Dev
  • Prompts included

Website Builder Setup

264 stars on GitHub5 commands
A skill that turns Claude Code into a complete web design studio for people who do not code. Rather than installing loose tools, it packages three integrated components into one setup: UI/UX Pro Max (50+ design styles, 161 color palettes and 57 typographic pairings to guarantee a professional look), Framer Motion (smooth animation — page transitions, hover effects and scroll reveals) and 21st.dev (100+ production-ready React components: buttons, navbars, hero sections, cards and footers). You describe the site you want in plain language and Claude handles design, layout, animation and responsiveness on its own.

Taste Skill

64,9 mil stars on GitHub6 commands
An anti-slop framework for frontend — it gives AI taste so it stops producing generic, lifeless interfaces. The point is to replace the models' predictable aesthetic with deliberate design decisions, controlled through three dials from 1 to 10: DESIGN_VARIANCE (from centered and clean to asymmetric and modern), MOTION_INTENSITY (from hover effects to scroll and magnetic animation) and VISUAL_DENSITY (from airy to dashboard-dense). The rules target design intent, not the API, so they hold in React, Vue, Svelte and the rest. The repository gathers 11+ skills — the default design-taste-frontend (v2), the gpt-taste variant for Codex, image-to-code (visual reference → implementation), redesign-existing-projects (an audit of existing projects) and style variants (soft, minimalist, brutalist), plus image generation skills (imagegen web/mobile, brandkit) with canonical GSAP skeletons and preflight checks.

The flow: install through npx skills → describe the UI while setting the 3 dials (variance / motion / density) → the AI produces frontend with deliberate design rather than slop

  • Anti-slop frontend
  • 3 dials (variance/motion/density)

Impeccable

47,9 mil stars on GitHub9 commands
A design direction system for coding agents, built by Paul Bakaus (formerly of Google). It goes after the generic interfaces AI tends to produce — the same gradients, the same fonts, the same predictable layout. /impeccable init documents the product context in PRODUCT.md and DESIGN.md (audience, brand, voice, components), and from there a vocabulary of 23 commands covers the whole cycle: planning (craft, shape), review (critique, audit, polish), intensity refinement (bolder, quieter, distill) and implementation (animate, colorize, typeset, layout). The technical differentiator is the anti-pattern detector with 45 deterministic rules — overused fonts, poor contrast, dated easing, small tap targets — which runs as a standalone CLI, with no API, CI included. It works in Claude Code, Cursor, Copilot, Gemini CLI and others.

The standard flow: npx impeccable install → /impeccable init → craft / critique / polish → npx impeccable detect in CI

  • 23 design commands
  • 45 anti-pattern rules
  • PRODUCT.md + DESIGN.md
  • Live iteration in the browser
  • Standalone CLI detector
  • Craft / Critique / Polish
  • CI integration
  • Multi-agent (Cursor, Copilot…)

Designer Skills Pack

1,9 mil stars on GitHub9 commands
A collection of agentic design skills for Claude Code and Gemini CLI — the motto: "design skills for the agent era, written so an AI agent can actually use them". In total there are 239 skills and 88 commands across 33 plugins, spread over 5 collections (this repository carries the Design Practice collection: 97 skills and 30 commands in 9 plugins; sibling repositories cover AI product design, UX program management, design leadership and inclusive design). The architecture separates skills as "nouns" (units of domain knowledge: research, design systems, UI, interaction, prototyping, design ops) from commands as "verbs" (workflows that chain skills together). Installation is modular — you add only the plugins you need, with no performance penalty.

Dembrandt

Tool2,2 mil stars on GitHub8 commands
A CLI that extracts any site's design system in seconds — point it at a URL and get the tokens back in a standardized, machine-readable format. It captures the color palette (semantic, CSS variables, gradients), typography, spacing scales, borders, shadows, motion tokens (durations, easing curves, hover patterns), component styles and framework detection. It analyzes up to 10 pages at a time (DOM or sitemap crawling), runs a WCAG audit with real contrast checking against the DOM (AA/AAA grades) and exports to JSON, W3C Design Tokens (DTCG), a PDF brand guide or DESIGN.md — the format AI agents read to generate on-brand UI. In CI it compares against a baseline and detects design drift (with an official GitHub Action); for agents it exposes an MCP server with 11 tools (get_design_tokens, compute_drift, export_dtcg…) for Claude Code, Cursor and Windsurf.

The flow: npx dembrandt [url] → pick the format (--design-md / --dtcg / --brand-guide) → use the tokens in the agent or compare against the CI baseline

Motion

Tool32,9 mil stars on GitHub4 commands
An open-source animation library for JavaScript, React and Vue — the successor to Framer Motion, built on a hybrid engine that combines JavaScript with native browser APIs for GPU-accelerated animation at 120fps. It covers springs and physics-based easing, gestures (hover, tap, drag), layout transitions, scroll-linked effects, timelines and sequencing — all in TypeScript, tree-shakable and with a minimal footprint. For coding agents, the ecosystem offers the Motion AI Kit (part of the Motion+ subscription): a single installer that sets up skills, an MCP server and documentation access for Claude Code, Cursor, Codex and others — including the source of 400+ Motion+ examples and MotionScore performance audits of Motion, CSS or GSAP animation.

The flow: npm install motion → animate with <motion.div> or animate() · with agents: npx motion-ai → skills plus MCP in the agent → ask for animation and audits

React Bits

Tool44,6 mil stars on GitHub4 commands
A library of 140+ animated, interactive, customizable React components — text animations, UI elements, backgrounds and 3D effects — built by David Haz (reactbits.dev). It is not a skill: it is the raw material an agent consumes to assemble memorable interfaces without building the animation from scratch. Every component exists in 4 variants (JavaScript or TypeScript × plain CSS or Tailwind), with minimal dependencies, tree-shakeable and ready to copy and paste — the per-component install through the shadcn CLI or jsrepo drops the code into your project, yours to edit. The site also offers free creative tools (Background Studio, Shape Magic, Texture Lab) and the family has ports for Vue (vue-bits.dev) and Svelte (sveltebits.xyz). MIT + Commons Clause.

The flow: pick the component at reactbits.dev → install the right variant through shadcn/jsrepo (or copy the code) → tune the props → the animation is in your project

  • 140+ animated components
  • Text animations · Backgrounds
  • UI elements · 3D effects

npx shadcn add @react-bits/[Component]Installs a component through the shadcn CLI

Installs the chosen component straight into the codebase through the shadcn registry — the suffix picks the variant (TS-TW = TypeScript + Tailwind; JS-CSS = JavaScript + plain CSS).

npx shadcn@latest add @react-bits/BlurText-TS-TW
Install through jsrepoThe alternative CLI route

The alternative route: jsrepo downloads the component in the variant named in the reactbits.dev registry URL into the project folder.

npx jsrepo add https://reactbits.dev/[variante]/[categoria]/[Componente]
Copy and paste from the siteNo CLI at all

Every component shows its complete code on the site — copy the variant you want and paste it into the project; dependencies, where they exist, are listed on the component's page.

https://reactbits.dev/
Ask the agent to use a componentThe agent integrates and customizes

With the library in the project (or the code pasted in), the agent integrates the component, adjusts the props (duration, delay, easing) and matches the colors to your design system.

68 stars on GitHub6 commands
A Claude Code skill that teaches the agent to generate production-grade web animation with the Motion.dev library from plain-language descriptions. It delivers TypeScript/JSX code at 120fps with GPU acceleration and spring physics for React, Next.js, Svelte, Vue, Astro and plain JavaScript, organized into pattern families: entrances (hero fade-up, stagger, scroll reveal), scroll effects (parallax, progress), gestures (card hover, magnetic button, drag carousel), micro-interactions and layout animation (list reordering through FLIP, accordions, tab switching). It enforces performance budgets (60fps+, bundle under 50KB, zero layout shifts) and accessibility through prefers-reduced-motion, using a progressive loading architecture (about 2,000 tokens of core; examples and references only enter the context when they are needed).

The skill's flow: Clarify (framework plus animation type) → Plan (pattern plus physics configuration) → Implement (GPU code) → Verify (performance plus accessibility)

Skills for Design Engineers

17,4 mil stars on GitHub6 commands
A collection of 6 skills that teach the agent animation and interface craft, built by Emil Kowalski — author of the Sonner and Vaul components, drawing on his work at Vercel and Linear. The premise: agents have no refined taste, and small errors (the wrong easing, the wrong duration) compound into worse interfaces — the skills encode those rules so the agent applies expert judgment by default. The set: emil-design-eng (the central design and animation guide), review-animations (a strict rule-based review), improve-animations (a codebase audit across 8 categories), find-animation-opportunities (where motion earns its place — and what to leave still), animation-vocabulary (precise language for asking for animation) and apple-design (Apple/WWDC interface principles adapted for the web). The plans it produces are self-contained and prioritized — written so a cheaper model can execute them without needing taste of its own.

The flow: npx skills add → audit with a capable model → get prioritized findings → generate self-contained plans → execute the plans with a cheaper model

Three.js Skills

2,8 mil stars on GitHub5 commands
A collection of 10 Three.js knowledge skills for Claude Code that closes a concrete gap: the agent knows programming in general, but not the API details, good practice and idiomatic patterns of the web's most used 3D library. Each skill covers one domain: fundamentals (scene, cameras, renderer, the Object3D hierarchy), geometry (native shapes, BufferGeometry, custom geometry), materials (PBR and shader materials), lighting (light types, shadows, ambient lighting), textures (UV mapping, environment maps), animation (keyframes, skeletal animation, morph targets), loaders (GLTF/GLB and async patterns), shaders (GLSL, ShaderMaterial), postprocessing (EffectComposer, bloom, depth of field) and interaction (raycasting, camera controls, object selection). These are knowledge skills — no slash commands: they activate contextually when the task involves Three.js.

The flow: clone (or add as a submodule) and copy .claude/skills into the project → ask for Three.js code in plain language → the right domain skill loads and the agent follows the API's patterns

Design Motion Principles

844 stars on GitHub6 commands
A motion design skill with two modes: Create (it builds interactive components with deliberate movement in React, Framer Motion, CSS or HTML) and Audit (it reviews the animation already in the codebase). What sets it apart is a system of three weighted "lenses", synthesized from the public work of three motion design references: Emil Kowalski (restraint and speed — "should this animate at all?"), Jakub Krehel (production polish — "is it subtle enough?") and Jhey Tompkins (creative experimentation — "what could this become?"). Each lens's weight adjusts to the project type (productivity tool versus children's app versus portfolio). It goes straight at AI "animation slop" with an anti-slop checklist (pulsing indicators, heavy blur entrances, universal hover-scale, stagger-spam, bouncy springs on utility actions) and detects missing movement (absent AnimatePresence, state changes with no transition). The audit comes out as a self-contained HTML report with looping CSS demos — or markdown with the --terminal flag. It is 15 files: a router, 2 workflows and 12 references (motion cookbook, gotchas, accessibility, performance).

The flow: npx skills add → ask for creation or an audit in plain language → the skill weights the 3 lenses by context → code with deliberate motion, or an HTML report with demos

Motion Design Skill

711 stars on GitHub5 commands
A universal motion design skill from LottieFiles (creators of the Lottie ecosystem) — the philosophy is "philosophy-first, implementation-agnostic": rather than teaching one library's API, it teaches the principles, which is why it works equally with CSS, Framer Motion, GSAP, Lottie and spring libraries. It puts the agent in the role of motion director, covering timing, easing, choreography and emotional intent — including Disney's 12 animation principles adapted for UI. It is 16 files across 4 sections: director/ (philosophical fundamentals, emotion-to-movement mapping, choreography strategies, adaptation by platform), patterns/ (entrance and exit, state feedback — loading/success/error/hover —, ambient motion and multi-element coordination) and reference/ (duration and easing tables, a property selection guide, quality checklists and troubleshooting), plus an 8-step checklist system and movement personality archetypes. It activates automatically on micro-interactions, entrance sequences, scroll-triggered work and brand motion identity.

The flow: npx skills add → describe the animation you want (or ask for a review) → the agent directs the motion by the principles and implements it in the stack you use

Scroll World

5,5 mil stars on GitHub6 commands
An agent skill that produces immersive scroll-driven landing pages: as the page scrolls, a camera flies from outside each scene into its interior and on to the next one with no cuts at all — one continuous flight through generated 3D worlds. The skill orchestrates the entire pipeline: it generates coherent isometric dioramas with image models, creates the frame-locked video connectors between scenes (through the Higgsfield CLI) and assembles it all on a scroll-scrubbing engine in portable vanilla JavaScript — it works in plain HTML, Next.js, Vue or pages served from Python. It includes an optional native 9:16 portrait rendering mode for mobile, rather than simply cropping the widescreen. Requirements: an authenticated Higgsfield CLI (with credits), ffmpeg/ffprobe and Python 3 with Pillow. Compatible with Claude Code, Codex, Cursor and 20+ agents.

The flow: install → ask for the "scroll-through world" landing (or /scroll-world) → the skill generates the scenes plus video connectors → the scroll engine assembles the continuous flight → optional: a 9:16 variant for mobile

Playwright

Tool93,1 mil stars on GitHub7 commands
Microsoft's framework for web application automation and testing, with one unified API across the three main browser engines — Chromium, Firefox and WebKit — on Linux, macOS and Windows. It solves the fragmentation of maintaining separate test suites per browser. The technical highlights: auto-waiting (it waits until the element is actionable, with no artificial timeouts) and web-first assertions that re-run until the condition holds; resilient locators that mirror how a user interacts (getByRole, getByLabel, getByPlaceholder); complete test isolation in separate browser contexts, with authentication states saved and reused; and full tracing (screenshots, video, DOM snapshots, network and console) inspectable in the Trace Viewer. It runs in JS/TS, Python, .NET and Java, parallelized by default.

The standard flow: npm init playwright@latest → codegen to record the test → playwright test in parallel → show-trace to debug failures

  • Chromium / Firefox / WebKit
  • Auto-waiting

Spec Kit

122,1 mil stars on GitHub12 commands
GitHub's toolkit for spec-driven development. It inverts the usual flow: rather than treating the spec as a disposable draft, the spec becomes the executable artifact the implementation is generated from. It counters "vibe coding" with a process in phases — a constitution defining quality principles, a specification focused on the what and the why (without fixing the technology), clarification of ambiguities, a technical plan with stack decisions, a breakdown into tasks ordered by dependency (with parallelism markers and TDD), systematic implementation, and a convergence step that compares the code against the spec. It integrates with Claude Code and 30+ agents through slash commands, and includes extensions, presets and bundles for organizational standards.

The full flow: /speckit.constitution → /speckit.specify → /speckit.clarify → /speckit.plan → /speckit.tasks → /speckit.implement → /speckit.converge

  • Spec-driven development

Ponytail

85,5 mil stars on GitHub6 commands
A skill that installs a lazy senior developer inside the agent, guided by one motto: the best code is the code never written. Before producing a single line, it applies a seven-level decision ladder: is the code actually needed? Does it already exist in the codebase? Does the standard library solve it? Does the platform have it natively? Does an installed dependency already do this? Does it fit in one line? If none of that holds, it writes only the minimum viable — leaving validation, error handling, security and accessibility intact. The numbers measured against a baseline without the skill: 54% fewer lines, 22% fewer tokens, 20% cheaper and 27% faster. It has three intensities (lite, full, ultra) and review commands that hunt for over-engineering in diffs and across the whole repository.

The standard flow: /ponytail full → write code as usual → /ponytail-review on the diff → /ponytail-gain to measure the impact

Superpowers

257 mil stars on GitHub6 commands
A complete software development methodology for coding agents, built on composable skills and starting instructions — created by Jesse Vincent and the Prime Radiant team. Rather than one isolated skill, it is the whole system: test-driven-development (the RED-GREEN-REFACTOR cycle with an anti-pattern reference), systematic-debugging (root cause analysis in 4 phases) and verification-before-completion; collaboration skills such as Socratic brainstorming, writing-plans and executing-plans (batched execution with checkpoints), dispatching-parallel-agents, requesting and receiving-code-review, using-git-worktrees, finishing-a-development-branch and subagent-driven-development (fast iteration with two-stage review); plus meta-skills (writing-skills, using-superpowers) for building new skills to the house standard. It is available in the official Claude Code plugin marketplace and installable in Codex, Cursor, Copilot CLI, Antigravity, Kimi Code, OpenCode, Factory Droid and Pi.

Agent Skills

91,1 mil stars on GitHub9 commands
Twenty-five skills that encode the quality gates a senior engineer applies, packaged so the agent follows the same rite through every phase of development. The spine is a six-stage cycle — define, plan, build, verify, review, ship — with a command for each. Skills also activate on their own from what you are doing: designing an API triggers the interface-design one, touching UI triggers the frontend one. The principle running through all of it is the same: spec before code, small atomic tasks, one slice at a time, and tests as proof — not as formality.

The cycle: /spec → /plan → /build → /test → /review → /ship

  • 25 skills

/plugin marketplace add addyosmani/agent-skills
Define what to buildA spec before any code

Turns an idea into a specification. This is the stage most people skip and the one that accounts for most of the rework later.

/spec
Plan how to build itSmall, atomic tasks

Breaks the spec into tasks that fit in one head at a time. Large tasks are where the agent loses the thread.

/plan
Build in slicesOne at a time, with verification

Implements incrementally. With /build auto it generates the plan and runs every task in one approved pass — each still test-driven and committed separately, pausing on failures or risky steps.

/build
Prove it worksTests as proof, not ritual

Activates the test-driven development skill, with red-green-refactor enforced rather than suggested.

/test
Review before the mergeFive axes of quality

A review aimed at code health, not just correctness. Also available on its own: npx skills add addyosmani/agent-skills --skill code-review-and-quality.

/review
Audit web performanceMeasure before optimizing

Audits application performance starting from measurement rather than a hunch — the order that avoids optimizing something that was never the bottleneck.

/webperf
Simplify the codeClarity over cleverness

Cuts accidental complexity. It is the counterweight to /build: building fast accumulates cleverness that has to be undone.

Web Quality Skills

2,7 mil stars on GitHub8 commands
A collection built on measurement, not guesswork, for optimizing web projects with Lighthouse, Chrome DevTools for agents, Core Web Vitals, WCAG and search guidance. Where interface guidelines tell you what to build, these skills tell you how to build it performant, accessible and search-ready. What sets it apart is its discipline about evidence: it keeps four types explicit — CrUX field data, first-party RUM, a controlled lab run and a DevTools trace — and refuses to let you confuse what each one answers. Works with any framework.

The method: measure in the field and the lab → diagnose the real bottleneck → fix → measure again

Skills For Real Engineers

242,5 mil stars on GitHub5 commands
The skills Matt Pocock uses every day to do real engineering — his phrase — as opposed to vibe coding. The thesis is a direct critique of process frameworks: approaches like GSD, BMAD and Spec-Kit help by owning the process, and in doing so they take away your control and make bugs in the process itself hard to resolve. These skills go the other way: small, easy to adapt and composable, they work with any model, and they are meant for you to hack on and make your own. They come from the author's personal .agents directory, with decades of engineering experience behind them.

The philosophy: small composable skills you adapt — not a framework that owns the process

anti-slop

Tool3,9 mil stars on GitHub6 commands
Opinionated Oxlint rules that reject low-signal patterns in TypeScript and JavaScript — the kind of code an agent produces when it lacks evidence and reaches for a defensive guess. The list is specific: no chained type assertions, no conditional empty-object spread, no known-value widening, no runtime typeof checks, no module mocking. The project asks to be vendored into your repository, not installed as a fixed dependency: you read the rules, adjust them to your team's standard, and the files become yours to maintain.

The model: copy the rules into the repo → read and adjust to your standard → maintain them as your own code

  • TypeScript
  • Vendored rules
  • No chained assertions
  • No module mocking
  • Effect rule group
  • Automatic setup

Install through the skillCopies, configures and validates on its own

Then just ask the agent to install it in the repository: it copies the plugin, installs current Oxlint dependencies, merges into the existing lint configuration, enables every generic rule and validates the result.

Compound Engineering

24,7 mil stars on GitHub7 commands
Thirty-three skills arranged so that each unit of work makes the next one easier. The loop is brainstorm, plan, build, review — and then capture what you learned, writing the knowledge down where the next change can read it. That last stage is the whole point of the project and what separates it from other process frameworks: without it, every task starts from zero and the team repeats the same mistakes under different names. It runs on fourteen agent hosts, including Claude Code, Cursor and Codex.

Diretrizes do Karpathy

209,1 mil stars on GitHub7 commands
A single CLAUDE.md file distilling four principles from Andrej Karpathy's public observations on where models fail at coding: they make wrong assumptions on your behalf and run along with them without checking, they do not manage their own confusion, do not seek clarification, do not present tradeoffs, do not push back when they should — and they love to overcomplicate, bloating a thousand lines where a hundred would do. The four principles attack exactly that: think before coding, simplicity first, surgical changes and goal-driven execution. It is the smallest configuration investment on this list with a noticeable effect — one file, no install, no dependency.

The test behind each principle: would a senior engineer call this overcomplicated? · does every changed line trace back to the request?

Think before codingPrinciple 1

State assumptions out loud, present the interpretations when there is ambiguity, push back when a simpler path exists, and stop when confused — naming what is unclear.

State your assumptions explicitly before you write any code
Simplicity firstPrinciple 2

Nothing beyond what was asked, no abstraction for single-use code, no unrequested flexibility, no error handling for impossible scenarios. If two hundred lines fit in fifty, rewrite it.

Write the minimum code that solves this. Nothing speculative.
Surgical changesPrinciple 3

Do not improve adjacent code, do not reformat, do not refactor what is not broken. Dead code you notice gets mentioned, not deleted. Remove only what your own changes orphaned.

Touch only what you must. Match the existing style even if you would do it differently.
Verifiable goalsPrinciple 4

Trade orders for success criteria. Instead of asking for validation, ask for tests on invalid input and make them pass. Strong criteria let the model loop on its own; weak ones require you at every step.

Write a test that reproduces the bug, then make it pass
Apply it in CursorSame rule, different editor

The repository ships a committed .cursor/rules/karpathy-guidelines.mdc, so the guidelines apply when you open the project in Cursor with no extra setup.

Knowledge & Graphs

Turn a corpus — code, documents, PDFs, video — into something the agent queries instead of re-reading

RAG-Anything

Tool22,3 mil stars on GitHub5 commands
An all-in-one multimodal RAG framework (Retrieval-Augmented Generation) that goes after a critical limitation of traditional systems: their inability to handle non-textual content. Real documents mix text, images, tables, equations and charts — and RAG-Anything processes and queries all of those modalities in a single pipeline. Built on LightRAG, it uses specialized parsers (MinerU, Docling, PaddleOCR) to extract content while preserving the document's hierarchy, assembles a multimodal knowledge graph with automatic extraction of entities and cross-modal relations, and answers through hybrid retrieval — including a VLM mode that calls vision models to analyze images inside the retrieved context. It supports PDF, Office (DOC/PPT/XLS), images and text.

The standard flow: process_document_complete (ingestion + parsing + graph) → aquery in hybrid mode → an answer drawing on text, tables and images together

  • Multimodal pipeline
  • MinerU / Docling parsers
  • PaddleOCR
  • Knowledge graph
  • VLM mode (vision)
  • Hybrid retrieval
  • PDF / Office / Images

Graphify

90,8 mil stars on GitHub10 commands
A skill that turns any folder — code, SQL schemas, documentation, PDFs, papers, images, video — into a queryable knowledge graph. You type /graphify in the assistant and it maps the whole project into interconnected concept nodes, which you then query instead of grepping files. Code is parsed locally and deterministically through tree-sitter ASTs (no LLM calls — none of the source leaves the machine), covering about 40 languages plus SQL and Terraform; docs and media use configurable API backends. Every edge in the graph is marked EXTRACTED (explicit in the source) or INFERRED (resolved by Graphify), and the output includes an interactive graph.html, a markdown report and exports to SVG, GraphML, Neo4j, Obsidian, a wiki and an MCP server. It works in 20+ assistants (Claude Code, Codex, Cursor, Gemini CLI…); a Y Combinator S26 batch project, with 90k+ stars.

The flow: graphify install → /graphify . → open graph.html / GRAPH_REPORT.md → query / path / explain instead of grep → graphify hook install for an automatic rebuild on every commit

Understand Anything

81,2 mil stars on GitHub9 commands
It solves a concrete, universal problem: you just joined a new team and the codebase is two hundred thousand lines — where do you start? A multi-agent pipeline scans the project, extracts every file, function, class and dependency, and builds a knowledge graph that opens in an interactive dashboard where each node is clickable, with a plain-English summary and its relationships in view. The line that defines the project is in its own README and is a good design yardstick: the goal is not a graph that wows you with how complex your codebase is, it is a graph that quietly teaches you how every piece fits together. A second, domain view maps the code onto business processes. And the author warns that the first run consumes a lot of tokens on a large project — later ones are incremental.

The path: /understand builds the graph → /understand-dashboard opens the view → /understand-chat answers the specific question

LLM Council

Tool23 mil stars on GitHub5 commands
A local web app by Andrej Karpathy that replaces a single LLM's answer with a council of models deliberating. The interface looks like an ordinary ChatGPT, but behind it the flow has 3 stages: (1) First Opinions — the question is dispatched in parallel to every council member through OpenRouter, with the answers shown in tabs; (2) Review — each LLM assesses and ranks the others' answers anonymously for accuracy and depth (without knowing whose is whose); (3) Final Response — a model designated Chairman synthesizes everything into one final answer. The default council brings together GPT-5.1, Gemini 3 Pro, Claude Sonnet 4.5 and Grok-4 — fully configurable in config.py for any OpenRouter model. The stack: FastAPI plus async httpx on the backend, React plus Vite on the frontend, storage in local JSON. The author himself describes it as "99% vibe coded" over a weekend — provided as is, with no support.

The flow: uv sync + npm install → .env with OPENROUTER_API_KEY → ./start.sh → ask at localhost:5173 → opinions in tabs → anonymous cross-ranking → the Chairman's synthesis

Deep Research Skills

1,7 mil stars on GitHub6 commands
A set of skills that assembles a deep research pipeline with a human in the loop inside Claude Code, OpenCode or Codex. The research splits into two controllable phases: first /research produces a structured outline — a list of research items with defined data fields — which you review and edit before spending tokens; then /research-deep dispatches web search subagents in parallel, one per item, to fill the structure in, and /research-report compiles it all into a markdown report. Intermediate commands (/research-add-items, /research-add-fields) expand the list or add columns before execution. The documentation is bilingual (English and Chinese) with use cases running from academic research and technical evaluations to market analysis and investment due diligence.

The full flow: /research [topic] → review and edit the outline → /research-add-items · /research-add-fields (optional) → /research-deep (subagents in parallel) → /research-report

  • Research in 2 phases

/last30days

60,8 mil stars on GitHub8 commands
An agent-led search engine scored by upvotes, likes and real money — not by editors. The observation behind it is a good one: each platform is a walled garden with its own API and auth, and no single AI reaches them all. Google does not touch Reddit comments, ChatGPT cannot search X, Gemini has YouTube but not Reddit. With your own keys and browser sessions, an agent searches all of them at once, scores them against each other, and synthesizes one brief. The depth is the differentiator: full YouTube transcripts, Reddit comments with upvote counts, Polymarket odds with real money behind them — not titles and links. Reddit, Hacker News, Polymarket and GitHub work with no key at all.

Security & Review

3 skills · 25 commands

Code auditing, autonomous pentesting and review that catches defects before the merge

Trail of Bits Skills

6,9 mil stars on GitHub9 commands
A plugin marketplace from Trail of Bits, one of the most respected security auditing shops in the field, with more than twenty plugins for agent-assisted security analysis. It splits by domain: smart contracts (vulnerability scanners across six blockchains), code auditing (C/C++ and Rust review, differential analysis of changes, supply-chain risk across npm, PyPI and Go), malware analysis (YARA rule authoring) and formal verification (timing side-channels in cryptographic code, mutation testing). What sets this catalogue apart from the generic ones is process rigour: there are plugins dedicated to verifying false positives before reporting, with mandatory gate reviews, and a triager that accepts, dismisses or asks for more information using seven brocards.

The flow: install the marketplace → pick the plugin for your domain → audit → verify false positives before reporting

  • Smart contracts
  • C/C++ and Rust review
  • Semgrep and CodeQL
  • SARIF
  • Supply chain
  • YARA rules
  • Mutation testing
  • Variant analysis

Lists the marketplace plugins by domain and installs the one you pick — you do not have to take all of them.

/plugin menu
Review changes with a security lensDifferential analysis with git history

Reviews only what changed, cross-referencing git history to understand why it changed — more accurate than reading the diff in isolation.

Use the differential-review plugin on my current branch against main
Understand the codebase before hunting bugsAudit context, one function at a time

Builds understanding of the codebase one function at a time, before looking for defects. Auditing without this step yields shallow findings.

Use audit-context-building to map this codebase before we look for vulnerabilities
Audit dependenciesSupply-chain risk across npm, PyPI and Go

Cross-references version-matched advisories, abandoned upstreams, publisher concentration and install scripts — the four vectors of dependency compromise.

Run supply-chain-risk-auditor on this project
Verify whether a finding is a false positiveA mandatory gate before reporting

Puts every finding through systematic verification with a mandatory review. This is the step that separates a useful report from noise.

Run fp-check on the findings before we report anything
Look for the same flaw elsewherePattern-based variant analysis

Found one bug, now find its siblings. Vulnerabilities rarely appear alone — the same wrong pattern is usually repeated.

Use variant-analysis to find similar vulnerabilities across the codebase
Find APIs that are dangerous by designRisky configurations and footguns

Identifies error-prone APIs, dangerous configurations and designs that invite misuse — defects that are not bugs, they are traps.

Run sharp-edges on this project
Write your own Semgrep ruleCustom detection with validation

Creates and refines a Semgrep rule for the pattern you want to catch, and a sibling plugin ports the rule to other languages with test-driven validation.

Use semgrep-rule-creator to write a rule that catches [pattern]

Strix

Tool59,6 mil stars on GitHub8 commands
Autonomous penetration testing agents that actually run your code, find vulnerabilities and validate them with a working proof of concept. That is the difference from a static scanner: instead of listing suspicions, Strix executes the exploit and hands you the PoC — which removes the mountain of false positives that makes automated security reporting useless. It ships the full offensive kit (HTTP interception proxy, reconnaissance, exploitation) and orchestrates teams of agents that collaborate. It runs two ways off the same engine: a local CLI with Docker and your own LLM key, or a managed platform over REST when there is no local infrastructure.

The flow: reconnaissance → exploitation → validation with a PoC → fix and re-scan

  • Autonomous pentest
  • Validated PoC
  • HTTP proxy
  • OWASP Top 10
  • Multi-agent
  • CI/CD
  • Autofix
  • Docker

Commands and Skills · 8

Install the nine skills in your agentGives Claude Code the ability to run pentests

Installs nine SKILL.md-compatible skills: local and managed pentesting, vulnerability remediation, CI scanning, and target-specific flows (application, web, API, OWASP Top 10).

npx skills add usestrix/strix
Install the CLILocal engine, sandboxed in Docker

Installs the executable. The first run pulls the sandbox Docker image on its own; results land in strix_runs/<name>.

curl -sSL https://strix.ai/install | bash
Configure the LLM providerAny supported provider

Points the engine at the model you want. Accepts OpenAI, Anthropic, Google and others.

export STRIX_LLM="openai/gpt-5.4" && export LLM_API_KEY="your-api-key"
First scanSecurity assessment of a directory

Runs the full cycle — reconnaissance, exploitation and validation — over local code, and writes the result with the PoCs.

strix --target ./app-directory
Test a web applicationTarget-specific web flow

Triggers the web application pentest flow, with the interception proxy and offensive kit pointed at the target.

Run a web application penetration test against [url] using Strix
Cover the OWASP Top 10A sweep through the canonical list

Walks the ten OWASP categories with exploit validation, rather than a checklist.

Open Code Review

Tool21,7 mil stars on GitHub8 commands
An AI code reviewer that started as an internal Alibaba tool — two years serving tens of thousands of developers and catching millions of defects before it was open sourced. It reads the git diff, sends the changed files to a configurable model through a tool-using agent, and returns structured comments with line-level precision. The agent reads whole files, searches the codebase and inspects other changed files for context, so the review is not just diff reading. The number that justifies its existence: against a general-purpose agent on the same model, it delivers markedly higher precision and F1 while consuming roughly one ninth of the tokens.

The flow: configure the model → review a diff or scan whole files → comments with the exact line

  • Diff review
  • Whole-file scan
  • Line-level precision
  • Delegation mode
  • JSON output
  • Session resume
  • Cross-platform
  • OpenSSF Gold

CLI Commands · 8

Configure provider and modelGuided interface, with a connectivity test

Picks the provider and model, asks for the key and tests connectivity on its own. Only skippable in delegation mode.

ocr config provider && ocr config model
Review what changedStaged, unstaged and untracked

Reviews every working-tree change at once — the everyday command, before opening the pull request.

ocr review
Review a whole branchFrom where it diverged from the base

Uses merge-base, so it reviews only what the branch introduced, without repeating what came from main.

ocr review --from main --to feature-branch
Review a specific commitOne point in the history

Useful for retroactively reviewing a change that already landed, or investigating where a defect came from.

ocr review --commit abc123
Scan whole filesWithout depending on git history

Reviews full contents instead of the diff. This is the right mode for auditing an unfamiliar codebase or a directory with no recent change.

ocr scan --path internal/agent
Save the result to a fileJSON, recommended for agents

Delivers structured output for the agent to consume, rather than prose for a human to read.

ocr review --format json --output result.json
Resume an interrupted reviewPicks up where it stopped

A long review does not restart from zero when it drops — list the sessions and resume the one that matters.

ocr session list && ocr review --from main --to feature-branch --resume <session-id>
Delegate the review to your agentWith no model configured at all

OCR handles file selection and rule resolution, and your coding agent does the reviewing. No API key of your own required.

Classic and generative search: technical audits, AI citability and link acquisition

Claude SEO

15,9 mil stars on GitHub9 commands
Twenty-five sub-skills and eighteen specialist agents running in parallel across technical SEO, content quality (E-E-A-T), Schema.org markup, generative search optimization, local SEO, e-commerce and international SEO. A full-site audit spawns up to fifteen agents at once and finishes in minutes rather than hours. What sets it apart most is its stance on evidence: every recommendation carries the first-principle observation it rests on, its dependencies, an explicit how would we know this failed check and a leading indicator. It is falsifiable, not promotional — and anchored in Google's primary documentation rather than third-party blogs.

The flow: /seo setup → audit with parallel agents → prioritized plan with a falsifiability check

  • 25 sub-skills
  • 18 agents

OpenSEO

Tool15,5 mil stars on GitHub8 commands
An open-source alternative to Semrush and Ahrefs, for people who find those tools too expensive or too bloated. The model is pay as you go: you bring your own DataForSEO key and pay them directly, with no subscription. It covers keyword research, rank tracking, competitor intelligence, backlinks, site audits and AI visibility — with focused workflows rather than a full suite. It exposes an MCP server so your agent can use your SEO data directly, and ships skills that walk the agent through the tasks. You can self-host it, with Docker or Cloudflare.

The model: your DataForSEO key → MCP exposed to the agent → skills that guide the flow

  • MCP server
  • DataForSEO
  • Keyword research
  • Rank tracking
  • Backlinks
  • Site audits
  • AI visibility
  • Self-hostable

GEO-SEO Claude

9,9 mil stars on GitHub8 commands
A skill that optimizes for where traffic is going, not where it was — the phrase is the project's own. It treats ChatGPT, Claude, Perplexity, Gemini and Google's AI Overviews as search destinations, without abandoning classic SEO. It analyzes content citability, AI crawler access through robots.txt, brand authority via mentions on the platforms AI cites, structured markup and platform-specific optimization. The bet behind the project is numerical: AI-referred traffic growing more than 500% year over year against a projected halving of classic search traffic by 2028.

The flow: audit with parallel subagents → citability and crawler access → client-ready report

  • ChatGPT and Perplexity
  • AI Overviews
  • Citability
  • llms.txt
  • AI crawlers

Qwoted SEO Backlinks

124 stars on GitHub7 commands
PR automation on top of Qwoted, to earn white-hat backlinks through citation in major publications. The agent finds journalist requests, builds sourced statistics pages as linkable assets, and sends the pitches. The thesis behind the design is a three-stage multiplier, and it is worth understanding: a pitch that links to a thoroughly sourced statistics page earns recurring citations for months, because the next reporter searching for statistics on that topic finds the page on your domain and cites it on their own. Sending is dry-run by default.

The multiplier: capture a journalist request → build the statistics page → pitch pointing at it

  • Qwoted
  • PR outreach
  • White-hat backlinks
  • Linkable asset
  • Statistics page
  • Automated pitching
  • Dry-run by default

Marketing Skills

40,6 mil stars on GitHub10 commands
The most popular marketing skill library in the ecosystem (39k+ stars), built by Corey Haines, founder of Conversion Factory. It is 50+ interconnected skills that give Claude the repertoire of a senior marketing team: CRO (landing pages, signup, onboarding, paywalls), copywriting and cold email, technical SEO and AI-SEO (visibility inside LLM answers), paid media, analytics, churn prevention, pricing and market research. The architectural twist is the product-marketing skill acting as the foundation: every other one consults it first to understand positioning, audience and product context before doing anything. All of it runs on plain language — describe the task and the right skill takes over, applying established frameworks and good practice rather than improvising.

8,6 mil stars on GitHub9 commands
Paid-media operations across twelve platforms — Google, Meta, YouTube, LinkedIn, TikTok, Microsoft, Reddit, Snapchat, X, Apple, Amazon and Pinterest — turning authorized exports into source-grounded audits, plans, creative workflows, experiments and reports. The design decision that matters most: it is read-only by default. Live changes stay disabled until the specific operation passes approval, idempotency, verification, audit and rollback gates. Every platform has its own skill, audit worker and capability declaration. And the system explicitly reports missing data, stale sources and contradictions, instead of filling gaps with assumptions.

Aaron Marketing Skills

2,7 mil stars on GitHub7 commands
One hundred and twenty skills organized as an entire marketing department, across seven disciplines of sixteen skills each — narrative, SEO and GEO, social, email, paid ads, influencer and launch — plus a protocol layer with shared registries. Each discipline follows four named phases, and all 120 skills obey the same contract (trigger, quick start, expected outputs, data sources, instructions, next skill), which makes them work as an operating system rather than a collection. Two architectural choices deserve attention: everything works without an API key at the first tier, on data you paste or pull from free sources; and eight quality gates emit machine-checkable verdicts, not vibes.

Postiz

Tool35,3 mil stars on GitHub6 commands
A social media scheduling tool built to be operated by an agent. It publishes to Instagram, YouTube, LinkedIn, TikTok, X, Bluesky, Mastodon, Discord and others, measures results with analytics and supports team work. What puts it in this catalogue is the automation layer: on top of the API, which already pairs with N8N, Make and Zapier, the project shipped a CLI of its own for agents. There is a hosted version and a self-hosted option, on a pnpm monorepo architecture.

Context & Memory

The agent forgets between sessions and pays dearly to re-read: persistent memory, compression and current documentation

Headroom

Tool59,8 mil stars on GitHub6 commands
A context compression layer for AI agents that cuts token consumption by 60-95% while preserving answer quality. It compresses tool output, logs, files, RAG chunks and conversation history before they reach the LLM. It offers four deployment modes — a library (Python/TypeScript), an HTTP proxy (drop-in, no code changes), an MCP server and a CLI wrapper for existing agents. The compression is content-aware: SmartCrusher for JSON, CodeCompressor for code ASTs and the Kompress-v2 model for prose — the ContentRouter detects the type and picks the algorithm. CCR (Content Cached Reversibly) keeps the original locally so the LLM can retrieve it on demand, and the CacheAligner stabilizes prefixes to improve the provider's KV cache hits. It also includes memory sharing between agents (Claude, Codex, Gemini) with deduplication, and the headroom learn command, which mines failed sessions and writes corrections into CLAUDE.local.md / AGENTS.md.

The standard flow: pip install → headroom wrap [agent] (or headroom proxy) → use the agent as usual (compression is transparent) → headroom learn --apply → monitor with headroom dashboard

Context Engineering Skills

17,3 mil stars on GitHub9 commands
A collection of 17 skills that teach the agent context engineering — the discipline of "finding the smallest possible set of high-signal tokens that maximizes the probability of the desired outcome". It covers the whole cycle: context fundamentals, degradation patterns (lost-in-middle, poisoning, distraction), compression and compaction strategies, multi-agent architectures (orchestrator, peer-to-peer, hierarchical), memory systems, tool design, evaluation with LLM-as-a-Judge, harness engineering and self-improvement loops. The rigor is unusual for the genre: the skill router was benchmarked across 4 frontier models (600 calls, 84-92% top-1 accuracy) and the repository is cited in peer-reviewed academic research (Peking University, 2025; a CMU/Yale/JHU survey, 2026). It includes 6 complete example systems and follows the Open Plugins specification — it works in Claude Code, Cursor and Codex.

Claude-Mem

92,7 mil stars on GitHub7 commands
A persistent memory compression system: five lifecycle hooks capture what happens in a session, a local service stores it in SQLite with a Chroma vector database for hybrid search, and the next session starts already holding the context of the ones before. The search design is what deserves attention — three layers instead of dumping everything: search returns a compact index of identifiers (50 to 100 tokens per result), timeline shows what was happening around them, and get_observations fetches full detail only for the identifiers that survived the filter. The stated saving is roughly tenfold in tokens, by filtering before fetching.

The three layers: search (index) → timeline (surrounding context) → get_observations (detail only for what you filtered)

  • 5 lifecycle hooks
  • SQLite
  • Chroma vectors
  • 4 MCP tools
  • 3-layer search
  • ~10x fewer tokens
  • Web viewer
  • OpenCode and Antigravity

Context7

Tool61,4 mil stars on GitHub6 commands
It solves one specific, daily problem: the model knows a library from the version that was in its training data, so it produces outdated examples and APIs that do not exist. Context7 pulls up-to-date, version-specific documentation and code examples straight from the source and places them in the prompt. You just add use context7 to the request. It works two ways: as a CLI plus skill, guiding the agent to fetch documentation without requiring MCP, or by registering an MCP server so the agent calls the tools natively.

The use: write the request normally and append "use context7" — the right documentation enters the prompt

  • Current documentation
  • Version-specific
  • CLI + Skill

Context Mode

20,3 mil stars on GitHub8 commands
It calls itself the other half of the context problem — and the phrase is precise. Where persistent memory handles what survives between sessions, Context Mode handles what the agent consumes within one: it runs commands in a sandbox and indexes content into a persistent FTS5 store, so results arrive filtered rather than raw. It registers six lifecycle hooks and eleven MCP tools — six sandbox tools and five meta-tools, among them a doctor that validates runtimes, hooks, FTS5 and plugin registration. Routing is automatic in Claude Code: the session-start hook injects instructions at runtime, writing no file into your project.

The idea: execute and index in a sandbox → the agent receives the filtered result, not the whole output

Planning with Files

26,5 mil stars on GitHub6 commands
The line that defines the project is your agent's context window dies, the plan does not. Rather than trusting a prompt the agent might ignore, it keeps three files on disk — task_plan.md, findings.md and progress.md — and uses lifecycle hooks that fire every turn to re-inject the planning context. The plan survives context loss, /clear, crashes and compaction. The author backs the claim with numbers: three wins out of three blind A/B tests, and a 96.7% assertion pass rate on the benchmark. It installs across 60-plus agents.

The mechanism: three files on disk + a hook that fires every turn = a plan that survives /clear

Caveman

102 mil stars on GitHub6 commands
The motto is the summary: why use many token when few token do trick. There are two products with the same purpose of cutting tokens, attacking opposite ends. The original skill makes the agent answer in clipped speech, keeping code, commands and error messages exact — it saves output. The proxy, which came later, shrinks what the agent reads before every provider call, with byte-exact recovery — it saves input, and a pinned Claude Code benchmark reports 33.2% fewer provider-reported input tokens. You can use one, the other, or both.

Two ends: the skill cuts what the agent writes, the proxy cuts what it reads

Browser & Automation

Give the agent a real browser: click, fill, test and capture the screen

agent-browser

Tool41,6 mil stars on GitHub9 commands
A browser automation CLI written in native Rust, built for agents. The workflow is what sets it apart: instead of the agent guessing at a CSS selector, it asks for a snapshot — the accessibility tree with short refs — and then acts by ref (click @e2, fill @e3). That makes the interaction readable and stable. Another detail that shows maturity: a click fails early when another element covers the click point, such as a consent banner or a modal, and reports which element is on top — instead of clicking the wrong thing and carrying on. It needs neither Playwright nor Node for the daemon.

The cycle: open → snapshot (tree with refs) → act by ref → screenshot → close

  • Accessibility tree
  • Action by ref

Playwright CLI

Tool13 mil stars on GitHub8 commands
A command-line interface for Playwright, with skills built in. The README carries an honest comparison against Playwright MCP itself, and it is worth reading before choosing: the CLI suits coding agents better because invocations are more token-efficient — they avoid loading a large tool schema and a verbose accessibility tree into context, letting the agent act through short, purpose-built commands. MCP still makes sense for specialized agentic loops that benefit from persistent state and iterative reasoning over page structure, such as exploratory automation and self-healing tests.

Octogent

Tool1,4 mil stars on GitHub6 commands
A dashboard for orchestrating several Claude Code sessions running in parallel over different parts of the same codebase. It solves a concrete pain — "too many terminals, not enough tentacles": when several agents work at once (docs, database, API, frontend), the context fragments and control slips. The central abstraction is the tentacle: a work container with its own scope, kept under .octogent/tentacles/, each with its CONTEXT.md (documentation for the area), todo.md (an executable task list) and notes — so each agent keeps persistent local context instead of rebuilding it from chat history. It launches and manages terminals through a unified panel, supports parent-child relationships between agents, communication between them (status, blockers, handoffs) and optional isolation through git worktrees.

The flow: octogent opens the panel → you create tentacles by area → assign an agent to each → they report progress and hand off to each other

  • Multi-agent Claude Code
  • Scoped tentacles
  • CONTEXT.md + todo.md
  • Communication between agents
  • Isolation by worktree
  • Web panel (port 8787)
  • Parent-child relationships
  • Needs Node 22+ / the claude CLI

gstack

130,6 mil stars on GitHub9 commands
The entire engineering team as slash commands, written by Garry Tan, president of Y Combinator. Twenty-three specialists and eight power tools: a CEO who rethinks the product, an engineering manager who locks the architecture, a designer who hunts AI slop, a reviewer who finds production bugs, a QA lead who opens a real browser, a security officer who runs OWASP and STRIDE, and a release engineer who ships the PR. What separates it from a command pack is the order: the skills run in sprint sequence and each one reads what the last one wrote — /office-hours produces the design doc /plan-ceo-review reads, and /plan-eng-review produces the test plan /qa executes. The author backs his own productivity claim with an appendix that concedes raw lines of code inflate under AI and lays out the normalized methodology — rare in a README that is also a pitch.

The sprint: Think → Plan → Build → Review → Test → Ship → Reflect — nothing falls through, because every step knows what came before

Sprint Commands · 9

InstallThirty seconds

Requires Claude Code, Git and Bun 1.0+ — plus Node on Windows. Setup registers one Stop hook that closes dangling session-timeline entries; it fails open and can never block a session.

git clone --single-branch --depth 1 https://github.com/garrytan/gstack.git ~/.claude/skills/gstack && cd ~/.claude/skills/gstack && ./setup
Start at the startBefore you write code

Six questions that reframe the product, challenge the premise and generate alternatives. The design doc it produces feeds every downstream step.

/office-hours
Rethink the problemThe ten-star product

Looks for the better product hiding inside the request. Four modes: expansion, selective expansion, hold scope and reduction.

/plan-ceo-review
Run every reviewerOne command, a reviewed plan

Runs CEO, design, developer experience and engineering in sequence — engineering always last, because it is the shipping gate. Only taste decisions come back to you.

/autoplan
Review the codeThe bug that passes CI

Looks for what blows up in production despite green tests. Fixes the obvious ones, flags completeness gaps, and carries a simplification lens that only advises — it never blocks and never auto-applies.

/review
Test in a real browserChromium, clicks and screenshots

Finds bugs, fixes them in atomic commits, re-verifies, and generates a regression test for every fix. /qa-only runs the same sweep without touching the code.

/qa
Audit securityOWASP Top 10 and STRIDE

Built for zero noise: seventeen false-positive exclusions, an 8/10 confidence gate and independent verification of each finding. Every finding ships with a concrete exploit scenario.

/cso
Turn on the guardrailsBefore touching production

Combines /careful, which warns before rm -rf, DROP TABLE and force-push, with /freeze, which restricts edits to one directory. /unfreeze releases it.

/guard
Close the loopFrom tests to PR

Syncs main, runs the tests, audits coverage, pushes and opens the PR. /land-and-deploy takes you from approved to verified in production, and /canary watches the deploy after.

/ship

Ruflo

Tool70 mil stars on GitHub8 commands
The thesis is an equation: Agent = Model + Harness. The model writes; the harness supplies tools, memory, loops, sandboxes and controls so the work actually happens — and Ruflo is the harness, the execution layer wrapped around Claude Code and Codex. It brings over a hundred specialized agents, swarms in hierarchical, mesh or adaptive topology, vector memory that learns from every task, and federation across machines. The README does something almost none do: it compares the two install paths in an honest table, making clear that the plugin writes nothing into your directory and gives only slash commands, while the CLI's init installs 98 agents, an MCP server, hooks and a daemon — and does touch your project.

The loop: router → swarm → agents → memory → learning, and back to the router

  • Meta-harness
  • 100+ agents
  • Swarms with consensus
  • Vector memory
  • Zero-trust federation
  • 35 plugins

The light pathZero files in your project

Then /plugin install ruflo-core@ruflo and whatever else you want. It gives slash commands and agent definitions without touching the working directory — good for trying it before committing.

/plugin marketplace add ruvnet/ruflo
The full loopInteractive wizard

Runs identically on every platform, PowerShell and cmd included. It writes .claude/, .claude-flow/, CLAUDE.md, hooks and a daemon. The curl install needs a POSIX shell and will not work on native Windows.

npx ruflo@latest init wizard
Register it as MCPNative tools in the agent

Watch the tool names: through the plugin they appear as mcp__plugin_ruflo-core_ruflo__*, not under the short names the CLI install uses.

claude mcp add claude-flow -- npx ruflo@latest mcp start
Coordinate a swarmSeveral agents as a team

Hierarchical, mesh or adaptive topology, with consensus. ruflo-autopilot leaves the agents running in an autonomous loop.

/plugin install ruflo-swarm@ruflo
Give it lasting memoryHybrid search and graph hops

Built on AgentDB with an HNSW index. The project's own audit measures a gain above the crossover point and a tie below it — the honest number, not the marketing one.

/plugin install ruflo-rag-memory@ruflo
Federate across machinesSlack for agents

A remote agent starts untrusted: identity proven via mTLS and ed25519, PII stripped before anything leaves your node, and a behavioural score that only rises with history and drops instantly. You run federation init and federation join; the protocol handles the rest.

/plugin install ruflo-federation@ruflo
Run work in the backgroundTwelve automatic workers

Audit, optimization and test-gap hunting fire on their own on a timer. After init, the hooks system routes tasks without you learning the 314 MCP tools.

/plugin install ruflo-loop-workers@ruflo
Turn it into your own kitMetaHarness

MetaHarness audits the environment before you ship: a 1-100 readiness grade, a configuration scan for security issues, and a project snapshot to catch regressions over time. eject converts the project into a standalone agent toolkit under its own name.

SuperClaude Framework

23,9 mil stars on GitHub8 commands
A meta-programming configuration framework that turns Claude Code into a structured development platform through behavioral instruction injection. Three layers: 30 slash commands covering the cycle from brainstorming to deployment, 20 specialized agents by domain, and — what actually separates it from a command pack — 7 behavioral modes that change how the agent thinks: brainstorming, business panel, deep research, orchestration, token efficiency, task management and introspection. The honesty deserves noting: the README opens its install section by warning that the TypeScript plugin system described in the older documentation does not exist yet and is planned for v5.0, with no ETA.

ECC

245,1 mil stars on GitHub9 commands
A harness operating system: 68 subagents, 284 skills and 94 commands, organized by a separation of roles that is the most instructive part of the project — a skill loads on demand, an agent isolates context and permissions, a rule is always loaded (so install few), a hook runs outside the model's context, and an instinct is a pattern learned from real sessions, with a confidence score. The README's motivation table is honest to the point of stinging: asking the model to use TDD is an instruction it may forget, whereas in ECC it becomes a gated workflow with red evidence captured before green. And AgentShield treats the agent's own configuration as an attack surface — a rare and correct idea. The headline of 2.1 is Plan Canvas: the plan opens in a local browser and you review it by pointing, with anchored annotations, instead of retyping.

The trail it leaves: plan → failing test → passing test → fresh-context review → verification — evidence, not just code

The planner writes an editable plan before any implementation, instead of letting it vanish into chat history.

/ecc:plan "Add user authentication with OAuth"
Review the plan by pointingPlan Canvas

The plan opens in a local page: you click the part you mean, attach numbered annotations, chat from a side rail, and approve or request changes. The verdict maps straight onto /ecc:plan's confirm gate.

ecc-plan-canvas
Implement test-firstRed, green, refactor

It captures the failing-test evidence before implementation. It is not a reminder in the prompt — it is a gate.

BMad Method

52,5 mil stars on GitHub8 commands
An agile method for AI-driven development, with a thesis that sets it apart from the rest: the process sizes itself to the work. A small change goes straight to build; a complex initiative gets the depth it needs. The diagnosis behind it is precise — assistants are effective at implementation, but they turn unstated assumptions into code, and BMad exists to make the decision explicit and preserve it as context for whatever follows. It serves both greenfield projects and inherited codebases, and there is an ecosystem of modules: a skill builder, a creative suite, an enterprise test architect, a game studio, and BMad Loop, which builds, verifies and retros an entire epic unattended.

The loop: a vague notion enters at Clarify · a clear idea at Plan · a small change straight at Build — and Learn loops back to Plan

The split is what makes it practical: contextual skills that load themselves when the conversation touches the subject, and slash commands you invoke deliberately. It covers Workers, Pages, storage via KV, D1 and R2, AI via Workers AI and Vectorize, Durable Objects for stateful coordination, and the whole of Cloudflare One — Access, Gateway, WARP, Tunnel, Magic WAN, DLP and CASB — including a skill dedicated to migrating off Zscaler, Palo Alto and legacy VPNs. It ships alongside five of Cloudflare's own remote MCP servers, among them an always-current documentation server and an observability one.

Google Agent Skills

19 mil stars on GitHub9 commands
The official Google repository, with more than a hundred and twenty skills for the company's products — and the breadth is the point: it runs from GKE, BigQuery, Cloud Run, Spanner and AlloyDB to Gemini on Agent Platform, Genkit in four languages, the Google Ads API, the Mobile Ads SDK and Google Analytics. Two things deserve attention. The first is the multi-product solution skills, which describe a whole architecture rather than a single service: RAG for enterprise search with GKE and AlloyDB, a serverless app with strictly private tiers, migrating AI workloads to GKE inference. The second is the Well-Architected Framework family, one skill per pillar — Google's architecture doctrine entering the workflow instead of sitting in a PDF.

Skills CLI (skills.sh)

Tool26,8 mil stars on GitHub7 commands
The open CLI of the agent skills ecosystem — the npx skills that shows up in half the installations in this catalog. Built by Vercel Labs with the skills.sh registry, it solves distribution: a skill is a folder with a SKILL.md, but every agent keeps skills somewhere different — the CLI installs from GitHub, GitLab, any git repository or a local folder straight into the correct configuration location for 70+ coding agents (Claude Code, Cursor, Codex, OpenCode, Copilot, Cline, Windsurf, Zed…). It supports project or global scope (-g), installation by symlink (the default) or copy (--copy), filtering to individual skills (--skill), targeting by agent (-a) and a non-interactive mode (-y) for CI/CD. Beyond installing, it has registry search (find), management of what is installed (list, update, remove), scaffolding for a new skill (init) and use mode — which injects a skill into a session ephemerally, installing nothing.

The flow: npx skills find [topic] → npx skills add [owner/repo] → the skill lands in the agent's correct directory → npx skills update keeps everything current

The repository doubles as a plugin marketplace pre-registered in the Copilot CLI — installing a bundle is one command — and has a dedicated search site (awesome-copilot.github.com) with full-text search, a Learning Hub with about 24 guides and a machine-readable llms.txt. Even though it belongs to the Copilot ecosystem, it is required reading for anyone who wants to see the skill and agent format at scale.

The flow: search at awesome-copilot.github.com → copilot plugin install [bundle]@awesome-copilot → the instructions apply automatically by file pattern; agents and skills land in Copilot Chat/CLI

Installation and Commands · 3

copilot plugin install [plugin]@awesome-copilotInstalls a bundle from the marketplace

The marketplace comes pre-registered in the Copilot CLI — this single command installs any bundle of agents and skills from the collection.

copilot plugin install [plugin-name]@awesome-copilot
copilot plugin marketplace add github/awesome-copilotRegisters the marketplace manually

For custom setups: register the marketplace explicitly before the plugin install — the same pattern as Claude Code's plugin marketplace.

copilot plugin marketplace add github/awesome-copilot
Browse the collectionSearch on the official site

The official site indexes everything with full-text search; in the repository, the docs/README.skills.md, README.agents.md, README.instructions.md and README.plugins.md indexes list them item by item.

Awesome Claude Code

53,3 mil stars on GitHub5 commands
The ecosystem's canonical awesome list, with a declared emphasis on code quality, security and originality — not a link dump. It covers ground the other lists do not: status lines, alternative clients to the terminal, agent orchestration, memory persistence, observability and session monitoring, usage cost and linting. One thing worth knowing if you knew it before: the current iteration was relaunched deliberately to highlight what was not on the previous one, so a well-known project that vanished was not dropped — it is preserved in README_ALTERNATIVES and returns as the migration proceeds.

How to use it: begin at Start Here → go to the section for your problem → every entry carries created date, last commit, license and stars

Agentic Awesome Skills

45,7 mil stars on GitHub7 commands
A catalog of more than two thousand skills with a role reversal that sets it apart: AAS does not rank or recommend anything. Your agent is what inspects the project and picks the exact identifiers, reading the local catalog through a read-only MCP; AAS only validates the selection in memory and persists it as aas-stack.json, producing an immutable plan before any change. The project is explicit about what it does not guarantee: structural validity certifies neither semantic fit, nor compatibility, nor safety to apply. And it warns that installing the whole catalog into Antigravity can exhaust the context and drop the editor into a crash loop — which is why the installer refuses to run without an explicit selection for that target.

The flow: the agent inspects the project → searches the local catalog → picks the IDs → compose_stack validates → the CLI produces the plan → human review

Install and Curation · 7

Preview before writingA dry run that touches nothing

Run it without --dry-run only after reviewing the list. The installer uses a release-pinned shallow clone and checks the commit against the npm package's gitHead — if the tag moved, it stops before copying.

npx agentic-awesome-skills --skills brainstorming,backend-dev-guidelines --dry-run
Audit before installingRisk signals per skill

Reads the directories without executing them and reports command, network, credential, filesystem, privileged, destructive, symlink and binary signals. It is a review aid, not a safety certificate.

npx agentic-awesome-skills audit --skills brainstorming,backend-dev-guidelines
Install for your agentOne target at a time

Swap in --gemini, --codex, --kiro, --agy or --path ./my-skills. The full catalog includes instructions marked critical and offensive, authorized-use only — the CLI prints the risk summary first.

npx agentic-awesome-skills --cursor
Install a single skillThrough the GitHub CLI

An exact SKILL.md path so there is no ambiguity in a repository this size. gh skill preview shows it first. It is a GitHub CLI preview feature and may change.

gh skill install sickn33/agentic-awesome-skills skills/brainstorming/SKILL.md --agent github-copilot --scope user --pin v14.2.0
Pick a focused pluginInstead of installing everything

Thirteen bundles of ten skills each, by job: web apps, product design, security engineering, data and analytics, agent and MCP building, QA and testing, DevOps, accessibility, API platform, SaaS launch.

After that you just call it by name in the conversation, in the form "Use @brainstorming to plan a SaaS MVP".

Configure the local MCP, ask the agent to inspect the project and choose the IDs, review aas-stack.json, then run aas stack validate and aas stack plan before applying.

Claude Code Skills & Plugins

25,3 mil stars on GitHub8 commands
A library of 388 skills across twenty domains, with a conceptual distinction most collections never make: it separates skill (how to execute a task), agent (which task to do) and persona (who is thinking) — and explains how to combine the three. Coverage reaches well past engineering: C-level advisory with fourteen chairs, academic and clinical research operations, regulatory work across ISO 13505, MDR and SOC 2, productivity and finance. A practical detail that matters: the 706 Python tools are stdlib-only, with nothing to pip install, so they run anywhere Python runs. It works across thirteen coding tools, from Claude Code to Codex, Gemini CLI, Cursor and Aider.

The combination: the persona sets who thinks → the skill sets how to execute → the agent sets what to do — all three across one project arc

Install by Domain · 8

Add the marketplaceThe recommended path

Then install only the domain you care about, rather than everything. On Windows, clone with git clone -c core.symlinks=true and Developer Mode on, or the mirror trees check out as one-line text files.

/plugin marketplace add alirezarezvani/claude-skills
Install engineering24 core skills

With engineering-advanced-skills@claude-code-skills for the 93 advanced ones: RAG architect, database designer, CI/CD builder, MCP builder.

/plugin install engineering-skills@claude-code-skills
Install product and marketingThe two largest packs

49 marketing skills across eight pods, including AEO with an E-E-A-T audit and citation tracking across five LLMs. product-skills@claude-code-skills brings the 12 product ones.

/plugin install marketing-skills@claude-code-skills
Install the executive boardThe chair you were missing

Fourteen chairs — CEO, CTO, CFO, CMO, CRO, CPO, COO, CHRO, CISO, legal, data, AI, customers and engineering — plus executive mentoring and board meetings.

/plugin install c-level-skills@claude-code-skills
Install one skill aloneWithout the whole domain

It works for any of them: playwright-pro for testing, self-improving-agent for automatic memory curation, content-creator for content.

/plugin install skill-security-auditor@claude-code-skills
Use a personaWho is thinking

Three come ready: startup CTO, growth marketer and solo founder. A persona defines how the agent prioritizes and communicates, not just what it knows.

cp agents/personas/startup-cto.md ~/.claude/agents/
Install into another agentCodex, Gemini, OpenClaw

For Gemini CLI, clone and run ./scripts/gemini-install.sh. ./scripts/convert.sh takes it to Cursor and the rest — personas come along.

npx agent-skills-cli add alirezarezvani/claude-skills --agent codex
Chain a project arcThe orchestration protocol

Four patterns: a solo sprint switching persona by phase, a domain deep-dive with stacked skills, cross-review between personas, and a skill chain with no persona at all.
