Development Claude Skills
8 676 development skills from 759 authors. They write and change code. Half of them fit into 1 830 tokens or less — that is what one costs your context window when the agent loads it. 1 213 ship runnable scripts rather than instructions alone. 42 of them cannot work without an MCP server, most often rube. We also found 1 172 copies of these same skills sitting in other people's repositories — counted once here, not 1 172 times.

Headless, bounded repair of custom-code build failures in an already-generated Azure SDK PR. Thin wrapper over the shared azure-sdk-mcp:azsdk_customized_code_update engine in custom-code-only scope (editScope: CustomCode); the skill owns the iterate-until-green loop, capped by a per-language `maxIterations` read from repair-config.yml. WHEN: Copilot cloud agent runs on a release-planner Auto SDK PR labeled `auto-sdk-build-fix` that fails to build because of custom (non-generated) code. DO NOT USE FOR: full TypeSpec migrations, spec edits, API design review, manual fixing. INVOKES: azure-sdk-mcp:azsdk_customized_code_update.

Patterns and techniques for mitigating breaking changes during Azure management-plane SDK migration from Swagger/AutoRest to TypeSpec. Covers SDK-side customizations (partial classes, CodeGenType, CodeGenSuppress) and TypeSpec decorator customizations (clientName, access, markAsPageable, alternateType, hierarchyBuilding).
Resolve review comments on Azure management-plane .NET SDK PRs. Handles renaming types/properties, changing property types, and other API surface adjustments by updating TypeSpec client.tsp and regenerating.
Handles Azure SDK for .NET management-plane migrations from AutoRest/Swagger to TypeSpec; use for MPG, mgmt migration, or Azure.ResourceManager.* migration requests.

> Help create a minimal reproduction for a TypeSpec compiler or emitter bug. Use when a user provides TypeSpec source (pasted code or a GitHub URL) and describes an issue. Reproduces locally and reduces to a single-file repro.
> a changeset, and push. This skill is specifically for the language emitter packages (http-client-python, http-client-csharp, http-client-java) - NOT for core TypeSpec packages like compiler, http, openapi3, etc. Use when the user wants to finalize emitter changes, says things like "prep for pr", "prepare for PR", "validate and push", "add changeset", or "finalize changes".
Format the codebase with pnpm and recover from common formatting failures.
Writes TypeSpec http-client-python generator mock API tests (azure/unbranded/shared) from a Spector case. Use when given a Spector case link or a PR link that modifies Spector cases under http-specs/azure-http-specs.
> Generate Python SDK code from a TypeSpec specification using the local emitter. Use this skill when the user wants to generate/regenerate a Python client from a TypeSpec spec, provides a GitHub URL or local path to a TypeSpec project, or says things like "generate from this spec", "emit Python from this tsp", "regenerate the SDK", or "compile this TypeSpec for Python".
> Regenerate the local emitter and diff the generated code against the upstream baseline checked into autorest.python. Use this skill when the user wants to see how their emitter changes affect generated code compared to what's currently in production, says things like "diff upstream", "compare to baseline", "what changed vs production", "show me the diff", "how does this affect generated code", or wants to validate their changes produce the expected output differences.
Create a PR to bump TypeSpec/Azure Tools dependencies, update peer dependencies, or release a new version of the http-client-python package.
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.
Guided onboarding for OpenSpec - walk through a complete workflow cycle with narration and real codebase work.
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.
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.

Nuxt full-stack Vue framework with SSR, auto-imports, and file-based routing. Use when working with Nuxt apps, server routes, useFetch, middleware, or hybrid rendering.
Node.js package manager with strict dependency resolution. Use when running pnpm specific commands, configuring workspaces via pnpm-workspace.yaml, or managing dependencies with catalogs, patches, overrides, config dependencies, or the global virtual store.
Bundle TypeScript and JavaScript libraries with blazing-fast speed powered by Rolldown. Use when building libraries, generating type declarations, bundling for multiple formats, or migrating from tsup.
| dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.
MUST be used for Vue.js tasks. Strongly recommends Composition API with `<script setup>` and TypeScript as the standard approach. Covers Vue 3, SSR, Volar, vue-tsc. Load for any Vue, .vue files, Vue Router, Pinia, or Vite with Vue work. ALWAYS use Composition API unless the project explicitly requires Options API.
Apply VueUse composables where appropriate to build concise, maintainable Vue.js / Nuxt features.
Create and validate a minimal AGT Copilot CLI policy tailored to the repository being inspected.
Create an API review PR for an Azure SDK package using API Review Hub. **UTILITY SKILL**. USE FOR: "create API review", "open API review", "compare package versions", "APIView PR".
