Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
OpenAISkillopenai/codex/.codex/skills/update-v8-version/SKILL.md
Update Codex's pinned `v8` / `rusty_v8` versions, validate the release-candidate path, and investigate failed V8 canary or artifact builds. Use when asked to bump V8, update `rusty_v8` artifacts, prepare or validate a V8 release candidate, check `v8-canary`, or diagnose why a V8 version update no longer builds.
Graphify-LabsSkillGraphify-Labs/graphify/graphify/skill.md
Use for any question about a codebase, its architecture, file relationships, or project content — especially when graphify-out/ exists, where the question should be treated as a graphify query first. Turns any input (code, docs, papers, images, videos) into a persistent knowledge graph with god nodes, community detection, and query/path/explain tools.
MicrosoftSkillmicrosoft/generative-ai-for-beginners/.github/skills/azure-openai-to-responses/SKILL.md
Migrate Python apps from Azure OpenAI Chat Completions to the Responses API. Covers AzureOpenAI/AsyncAzureOpenAI client migration to the v1 endpoint, streaming, tools, structured output, multi-turn, EntraID auth, and model compatibility checks. Python-focused, Azure OpenAI-specific. USE FOR: migrate to responses API, switch from chat completions, openai responses, upgrade openai SDK, responses API migration, move from completions to responses, gpt-5 migration, azure openai python migration, chat completions to responses, AzureOpenAI to OpenAI client, python azure openai upgrade. DO NOT USE FOR: building new apps from scratch (start with responses directly), Node/TypeScript/C#/Java/Go migrations (this skill is Python-only), Azure infrastructure setup (use azure-prepare), deploying models (use microsoft-foundry).
browser-useSkillbrowser-use/browser-use/skills/browser-use/SKILL.md
Direct browser control via CDP for web interaction: automation, scraping, testing, screenshots, and site/app work.
browser-useSkillbrowser-use/browser-use/skills/cloud/SKILL.md
Documentation reference for using Browser Use Cloud — the hosted API and SDK for browser automation. Use this skill whenever the user needs help with the Cloud REST API (v2, v3, or v4), browser-use-sdk (Python or TypeScript), X-Browser-Use-API-Key authentication, cloud sessions, browser profiles, profile sync, CDP WebSocket connections, stealth browsers, residential proxies, CAPTCHA handling, webhooks, workspaces, skills marketplace, liveUrl streaming, pricing, or integration patterns (chat UI, subagent, adding browser tools to existing agents). Also trigger for questions about n8n/Make/Zapier integration, Playwright/ Puppeteer/Selenium on cloud infrastructure, or 1Password vault integration. Do NOT use this for the open-source Python library (Agent, Browser, Tools config) — use the open-source skill instead.
browser-useSkillbrowser-use/browser-use/skills/open-source/SKILL.md
Documentation reference for writing Python code using the browser-use open-source library. Use this skill whenever the user needs help with Agent, Browser, or Tools configuration, is writing code that imports from browser_use, asks about @sandbox deployment, supported LLM models, Actor API, custom tools, lifecycle hooks, MCP server setup, or monitoring/observability with Laminar or OpenLIT. Also trigger for questions about browser-use installation, prompting strategies, or sensitive data handling. Do NOT use this for Cloud API/SDK usage or pricing — use the cloud skill instead. Do NOT use this for directly automating a browser via CLI commands — use the browser-use skill instead.
browser-useSkillbrowser-use/browser-use/skills/qa/SKILL.md
QA-test a website or web app and return a 1-5 quality score (5 = flawless, 1 = broken) with evidence. Use when the user wants to test, QA, evaluate, score, or "check how good" a site, page, flow, or app — including a local dev server (e.g. "qa test localhost:5173", "does the checkout work?", "rate this landing page"). Drives a real Browser Use cloud browser, tunneling localhost automatically.
browser-useSkillbrowser-use/browser-use/skills/remote-browser/SKILL.md
Controls an isolated Browser Use Cloud browser from a sandboxed machine with the current Browser Use CLI.
browser-useSkillbrowser-use/browser-use/skills/x402/SKILL.md
Set up Browser Use Cloud payments with x402 — pay per request from a crypto wallet (USDC on Base mainnet), no signup or API key. Two setups it works out up front — "just use it" (set up a wallet so you or Claude Code can run cloud browser tasks paid from the wallet — Claude writes and runs throwaway scripts, nothing touches your codebase) or "build it in" (install the SDK and write the key + code into your project). Walks through wallet setup, funding, .env, and a ~$1 test run. Use when the user asks about x402, pay-per-use, USDC payments, or wants Browser Use Cloud without an API key. For the free-tier signup (reverse-CAPTCHA → API key), use `browser-use cloud signup` or the `cloud` skill instead.
MicrosoftSkillmicrosoft/TypeScript/.github/skills/api-client/SKILL.md
Instructions for working on the API client in ./packages/typescript
MicrosoftSkillmicrosoft/TypeScript/.github/skills/compiler-and-fourslash-tests/SKILL.md
How to write, run, and debug compiler tests and fourslash (LSP) tests in the TypeScript repository. Covers test file formats, directives, markers, baseline management, and the fourslash verification API.
MicrosoftSkillmicrosoft/TypeScript/.github/skills/mcfly/SKILL.md
Only invoke when explicitly instructed to
MicrosoftSkillmicrosoft/TypeScript/.github/skills/security-report-check/SKILL.md
Are you doing security research on this repo? This document covers what guarantees and non-guarantees are provided. Consult this document before reporting a security issue or conducting security research.
SupabaseSkillsupabase/supabase/.agents/skills/api-types/SKILL.md
Maintain Supabase API types. Use when changing generated API type declarations, OpenAPI schemas, or investigating API type deployment drift.
SupabaseSkillsupabase/supabase/.agents/skills/ask-the-docs/SKILL.md
Answer questions about the Supabase docs app (apps/docs) using documented architecture, build pipeline, and review-pattern notes, and apply feature-design principles (codebase reuse, coding minimalism) when proposing or critiquing changes. Use when the user asks "how does X work in the docs app?", "where does Y live?", "is this approach OK for the docs app?", or before writing non-trivial changes under apps/docs/ — especially anything touching the MDX pipeline, markdown generation, content components, federated docs, or contributor-facing authoring patterns. Can answer architecture questions with Mermaid diagrams when helpful.
SupabaseSkillsupabase/supabase/.agents/skills/clickhouse-logs-queries/SKILL.md
Write, review, and migrate Supabase logs queries against the ClickHouse-backed `logs` table (the `logs.all.otel` analytics endpoint). Use this whenever a task involves Logs Explorer SQL, the `log_attributes` map, querying a log `source` (edge_logs, postgres_logs, auth_logs, etc.), translating an old BigQuery `cross join unnest(metadata)` logs query to ClickHouse, or wiring analytics log SQL in `apps/studio/data/logs` and `apps/studio/components/interfaces/Settings/Logs`. Reach for it even when the user just says "logs query", "Logs Explorer", or pastes a BigQuery logs query to convert, not only when they name ClickHouse.
SupabaseSkillsupabase/supabase/.agents/skills/copywriting/SKILL.md
Write or audit UI copy (buttons, labels, empty states, error messages, tooltips, form text) anywhere in the monorepo. Load it before shipping or reviewing any user-facing text — including when copy is incidental to the task, like a new feature that adds buttons, toasts, dialogs, or validation messages.
SupabaseSkillsupabase/supabase/.agents/skills/dev-toolbar-review/SKILL.md
Safety rules for the dev toolbar, PostHog client, and feature flags. Use
SupabaseSkillsupabase/supabase/.agents/skills/edit-the-docs/SKILL.md
Restructure, reorder, and improve existing Supabase docs pages under apps/docs: clarity, connective text, section grouping, and brevity. Use when asked to edit, reorganize, restructure, tighten prose, add glue between sections, or split a page edit into stacked PRs. Not for net-new feature drafts, which belong to write-the-docs, and not for PR triage or verification, which belong to review-the-docs.
SupabaseSkillsupabase/supabase/.agents/skills/pm-the-docs/SKILL.md
Docs-PM decision support for the "Write the docs" authoring process — makes audience, stage, and cross-cutting scope calls during the Frame and Shape stages (including cross-repo product lookup via universe when accessible, else the public OSS path), and helps decide when a docs question needs to self-serve vs. escalate to a docs PM. Use when framing a new docs page or launch, deciding what product stage or audience a feature targets, judging whether a docs question needs PM sign-off, or confirming which product repos a launch spans.
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
