Claude Skills
The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 79 404 files from 1 741 authors, of which 61 763 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
Bulk-merge a Graphite stack into main via admin-bypass fast-forward push. Replaces the Graphite merge queue for rivet-dev/rivet. Invoke when the user says "merge the stack at <branch>", "ship everything through <branch>", "bulk-merge up to <branch>", "fast-forward main to <branch>", or any request to land multiple stacked PRs at once in one shot. Requires repo admin permissions (bypasses branch protection), Graphite (gt) CLI, and GitHub (gh) CLI. After the FF push, closes all in-scope PRs explicitly with `gh pr close` in parallel — GitHub does not auto-mark them as MERGED because their bases point at sibling stack branches, not main.
Continue working on an OpenSpec change by creating the next artifact. Use when the user wants to progress their change, create the next artifact, or continue their workflow.
Guided onboarding for OpenSpec - walk through a complete workflow cycle with narration and real codebase work.
Fast-forward through OpenSpec artifact creation. Use when the user wants to quickly create all artifacts needed for implementation without stepping through each one individually.
Archive multiple completed changes at once. Use when archiving several parallel changes.
Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
Start a new OpenSpec change using the experimental artifact workflow. Use when the user wants to create a new feature, fix, or modification with a structured step-by-step approach.
Sync delta specs from a change to main specs. Use when the user wants to update main specs with changes from a delta spec, without archiving the change.
Verify implementation matches change artifacts. Use when the user wants to validate that implementation is complete, correct, and coherent before archiving.
Generate a clear, concise GitHub PR title and description from the diff between two local git branches, and save it to prDescription.md in the repo root. Use this whenever the user asks to write, generate, draft, or update a PR description or PR title from local branch changes — including phrasing like "summarize this diff into a PR description," "write a PR description for my current branch," "create a PR title and description," or any request to compare a base and target branch for PR purposes. Trigger even if the user doesn't name specific branches; this skill knows how to default them.
Use when writing or editing Javadoc for Lettuce public API — new methods, classes, deprecations, or when a reviewer asks to fix or improve doc comments. Points to the full house ruleset in .agents/docs/javadoc.md (imperative method summaries, fixed tag order, @param/@return/@throws/@since/@deprecated house forms) and the rule that command-interface Javadoc is edited in the template, not the generated files. Trigger on "write javadoc for", "document this method", "add a deprecation notice", "fix the doc comment".
Use when adding a new Redis command — or a new overload/variant of one — to the Lettuce client. Covers the full flow: writing the command specification, designing the Lettuce API, adding argument types and the API template, running the interface generators, adding the builder/async/reactive/Kotlin implementations, and adding unit + integration tests. Trigger on requests like "add support for the <X> command", "implement <REDIS COMMAND> in Lettuce", "wire up a new command", or adding a new argument/overload to an existing command.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, test web applications, or extract information from web pages.
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Removes Open Harness hosted demo restrictions from a fork. Use when a maintainer wants to remove managed-template trial caps, hosted deployment gating, or "deploy your own" limits. Triggers on "remove demo limits", "remove trial limits", "remove hosted restrictions", "open this up for my fork", "remove managed template restrictions".

Design and implement web animations that feel natural and purposeful. Use this skill proactively whenever the user asks questions about animations, motion, easing, timing, duration, springs, transitions, or animation performance. This includes questions about how to animate specific UI elements, which easing to use, animation best practices, or accessibility considerations for motion. Triggers on: easing, ease-out, ease-in, ease-in-out, cubic-bezier, bounce, spring physics, keyframes, transform, opacity, fade, slide, scale, hover effects, microinteractions, Framer Motion, React Spring, GSAP, CSS transitions, entrance/exit animations, page transitions, stagger, will-change, GPU acceleration, prefers-reduced-motion, modal/dropdown/tooltip/popover/drawer animations, gesture animations, drag interactions, button press feel, feels janky, make it smooth.
