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. 79 437 files from 1 744 authors, of which 61 785 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.

**UTILITY SKILL** — Must be consulted before making any changes to packages under sdk/. Discovers and loads package-specific domain knowledge that prevents common mistakes. WHEN: "add feature to package", "fix bug in package", "modify package code", "regenerate from typespec", "change client library".
Interactive wizard that walks service teams through creating a package-specific skill for their Azure SDK package. Scans the package, detects customization patterns, scaffolds a SKILL.md with references, and validates with vally lint. The skill is placed inside the package''s .github/skills/ directory so find-package-skill discovers it automatically. WHEN: create package skill; add service skill; bootstrap skill for package; new package skill; skill for my SDK package; write skill for search; write skill for cosmos.
Author skipped Vitest spec files for newly added non-beta ai-projects features under test/. Use when new GA (non-beta) classes, methods, or namespaces appear in review/ai-projects-node.api.md and need test coverage. Generates .skip-ped specs with TODO markers so a human can add recordings, then verifies the file compiles via npm run test:node.
Apply language-specific post-emitter fixes to ai-projects after a TypeSpec regeneration writes directly into src/ and generated/. Use when reviewing the working-tree diff from `npm run generate:client`, validating the SDK diff against upstream TypeSpec commit descriptions, enforcing protected-file rules, reverting unwanted emitter changes (renames, parameter shapes, model deletions), and preparing the package for build verification. Runs after the regenerate-from-typespec skill.
Migrate Azure/azure-sdk-for-js to a user-specified minimum Node.js version while preserving any existing references above the target.
Regenerate the @azure/ai-projects client from the latest TypeSpec commit on Azure/azure-rest-api-specs. Use when refreshing emitted code, bumping the pinned tsp-location commit, running tsp-client update, or pulling in upstream Foundry spec changes. Handles the rename dance between tsp-location.saved.yaml and tsp-location.yaml, and captures upstream commit descriptions for post-merge validation.
**UTILITY SKILL** — Must be consulted for SDK development workflow tasks. Routes agents to the correct tools and documentation for building, testing, linting, formatting, provisioning, deploying, and other package development tasks. WHEN: "build package", "run tests", "lint code", "format code", "run checks", "prepare samples", "publish samples", "apply customization", "run migrations", "bump version", "extract API", "update snippets", "check API compatibility", "manage test recordings", "provision test resources", "deploy test resources", "create test resources", "set up test environment", "authenticate to Azure", "login to Azure", "release package", "increment version", "troubleshoot CI", "fix CI failure", "CredScan", "credential scan", "push recordings", "asset sync", "update recordings".
Commit ai-projects regeneration output to a new branch and open a draft GitHub PR against Azure/azure-sdk-for-js main. Use when the prior five regen skills are complete and you need to push the branch and create a draft pull request via the gh CLI. Stages five logical commits (emitter output, post-emitter edits, samples, tests, changelog). Never force-pushes; always opens as draft.
Re-record the ai-projects live test suite, push only the recordings whose playback passes to the Azure/azure-sdk-assets repo, and open a PR for the updated assets.json. Use when test recordings are stale, a recorded test fails in playback in CI, or new recorded tests need fresh recordings. Wraps TEST_MODE=record / TEST_MODE=playback runs, dev-tool test-proxy push, and a single-file assets.json PR via the gh CLI.
Domain knowledge for Azure AI Content Understanding. Use this skill to answer questions about Content Understanding concepts, analyzers, field schemas, API operations, and JavaScript SDK usage. Always consult official documentation before answering.
Update ai-projects CHANGELOG.md after a TypeSpec regeneration. Merges new items into the existing top (Unreleased) entry when present; otherwise creates a new top entry, classifying changes into Breaking Changes / Features Added / Bugs Fixed / Other Changes buckets and syncing package.json version as needed.
Guide SDK users through setting up their JavaScript / Node.js environment for Azure AI Content Understanding. Use this skill when users need help installing the SDK, configuring Azure resources, deploying required models, setting environment variables, or running samples.
Run a specific sample for the Azure AI Content Understanding JavaScript SDK. Use when users want to run a particular sample like analyzeUrl.js or analyzeInvoice.js.

Use when the user asks to strip watermarks, remove C2PA/Content Credentials, clean AI metadata, remove invisible /remove-claude-marks).
Creates durable, resumable workflows using Vercel's Workflow SDK. Use when building workflows that need to survive restarts, pause for external events, retry on failure, or coordinate multi-step operations over time. Triggers on mentions of "workflow", "durable functions", "resumable", "workflow sdk", "queue", "event", "push", "subscribe", or step-based orchestration.
Spin up a portless + tmux dev session for the Workflow SDK that gives each git worktree isolated `<branch>.<name>.localhost` URLs for the Next.js workbench and the observability UI, plus a Claude statusline that surfaces those URLs. Use only when the user asks for a "portless dev session", a "tmux dev layout for workflow", "worktree-isolated dev URLs", or wants to wire workflow dev URLs into the Claude statusline. Do not activate for the generic "start the dev server" / "run pnpm dev" task.
Migrates Temporal, Inngest, Trigger.dev, and AWS Step Functions workflows to the Workflow SDK. Use when porting Activities, Workers, Signals, step.run(), step.waitForEvent(), Trigger.dev tasks / wait.forToken / triggerAndWait, ASL JSON state machines, Task/Choice/Wait/Parallel states, task tokens, or child workflows.
Install and configure Vercel Workflow SDK before it exists in node_modules. Use when the user asks to "install workflow", "set up workflow", "add durable workflows", "configure workflow sdk", or "init workflow" for Next.js, Express, Hono, Fastify, NestJS, Nitro, Nuxt, Astro, SvelteKit, or Vite.
