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.

> (1) starting a new Rust project or workspace, (2) configuring Cargo.toml best practices, (3) setting up CI pipelines for Rust, (4) organizing a multi-crate workspace, (5) configuring clippy, rustfmt, and linting.
Reviews Rust test code for unit test patterns, integration test structure, async testing, mocking approaches, and property-based testing. Covers Rust 2024 edition changes including async fn in traits for mocks, #[expect] lint suppression, LazyLock test fixtures, and temporary scope changes affecting test assertions. Use when reviewing _test.rs files, #[cfg(test)] modules, or test infrastructure in Rust projects. Covers tokio::test, test fixtures, and assertion patterns.
Reviews serde serialization code for derive patterns, enum representations, custom implementations, and common serialization bugs. Use when reviewing Rust code that uses serde, serde_json, toml, or any serde-based serialization format. Covers attribute macros, field renaming, and format-specific pitfalls.
Reviews tokio async runtime usage for task management, sync primitives, channel patterns, and runtime configuration. Covers Rust 2024 edition changes including async fn in traits, RPIT lifetime capture, LazyLock, and if-let temporary scoping. Use when reviewing Rust code that uses tokio, async/await patterns, spawn, channels, or async synchronization. Also covers tokio-util, tower, and hyper integration patterns.
面向 Agent 的百度 API 搜索 Skill。用于中文“查一下/搜索/联网查/最近/最新/热点”等场景，调用百度百科和百度 AI Search API，保留原始结果、去重并生成 research pack。
>- Run a Meta-Harness-style optimization loop NATIVELY — automatically search over the scaffolding around a FIXED base model (memory, retrieval, context construction, prompt templates, summarization, tool-selection logic) by proposing candidate variants, scoring each on a cheap deterministic eval, and keeping a Pareto frontier of quality vs cost — using native Agent / Workflow / loop tools instead of a standalone Python harness. Use this whenever the user wants to optimize, evolve, tune, distill, or search over a harness, scaffold, prompt system, memory or retrieval policy, context-assembly code, or summarizer while keeping the model fixed; whenever they mention Meta-Harness, harness optimization, scaffold evolution, automatic prompt/memory optimization, an evolutionary or Pareto search over candidate implementations, or "make the harness/agent better without retraining"; and whenever the gain must come from the code AROUND the model rather than the model weights. Reproduces the Meta-Harness paper's method natively, with no claude_wrapper.py and no metered solver API.
Drupal Canvas Code Components - a framework for building interactive, server-side-rendered components in Drupal. Covers scaffolding with @drupal-canvas/create, the Nebula starter template, component architecture, and integration with Acquia Source Site Builder.
Connect to an Acquia Source ("Source powered by Drupal CMS") site — its JSON:API and MCP endpoints, OAuth2 auth, the @drupal-canvas CLI, and the Canvas Page API deploy workflow. Use when wiring an AI agent or app to a Source CMS site, building/uploading Drupal Canvas Code Components, deploying landing pages via the Page API, or registering the Source MCP server with Claude Code/Cursor.
Comprehensive guide for managing Drupal contributed modules via Composer, including updates, patches, version compatibility, and Drupal 11 upgrades. Use when updating modules or resolving dependency issues.
Search API configuration, boosting strategies, and processor patterns for Drupal. Covers index configuration, field types, custom boost processors, number field boosting, engagement metrics, and reindexing workflows.
>- changeset, fix lint/type/test/format failures, push, watch CI, merge the Version Packages PR, watch publish, and verify npm. Use when asked to "release this", "publish this package", "autoship", "cut a release", or fix build failures inside a release flow. For feature PRs use pr-creator; for PR monitoring use pr-babysitter; for new packages use scaffold-cli.
Generates folder structures, module contracts, middleware pipelines, and frontend/backend boundaries for TypeScript full-stack applications, and finds domain-informed deepening opportunities in existing codebases. Use when setting up project structure, organizing a monorepo, defining folder layout, designing backend modules, establishing team conventions, improving architecture outside a local diff, writing an architecture brief, or asking "how should I structure this app", "design the folder structure", "set up the architecture", "find architecture improvements", "make this codebase agent-friendly", or "set up guardrails for coding agents". For scaffolding a new Next.js repo use scaffold-nextjs, for a new TypeScript CLI use scaffold-cli, for multi-tenant domain or isolation strategy use multi-tenant-architecture, and for structural review of a local diff use pr-reviewer.
Audits the smallest relevant developer-facing surface of a library, CLI, SDK, or npm package across API contracts, errors, CLI behavior, public types, onboarding, and config. Uses candidate-first rule loading, bounded local evidence, and compact root-cause findings. Use when asked to "audit my CLI", "make this CLI agent-friendly", "is this API ergonomic", "review the developer experience", "improve these errors", "simplify first run", or "review my SDK". For end-user UI use ui-audit, for agentic-app trust use ax-audit, for docs prose use docs-writing, for README work use readme-creator, and for repo architecture use define-architecture. Inside a product that also ships a UI, this is the skill for the developer-facing half, so pick it when the complaint is about an import, command, error string, exported type, or config rather than a screen.
Provides architecture guidance for multi-tenant SaaS platforms on Cloudflare or Vercel. Covers platform choice, domain strategy, tenant identification and isolation, subdomain routing, custom domains and SSL, white-label setup, tenant context propagation, PSL submission, and mapping platform limits to pricing plans. Use when building a multi-tenant application or asking "how do I support multiple tenants", "build a white-label platform", "add custom domains", "route tenants by subdomain", or "map limits to plans". For general app folder structure use define-architecture; for scaffolding a new Next.js repo use scaffold-nextjs.
>- Monitors an open PR, detects it from the current branch, polls for conflicts, CI failures, review comments, and merge readiness, fixes safe issues, and reports only state changes. Monitor mode uses the Monitor tool when available, falling back to CronCreate/CronDelete; without either, run one-shot modes only. Use when asked to "babysit a PR", "watch this PR", "keep a PR green", "fix CI", "why is CI red", "resolve conflicts", "triage review comments", or "address PR comments". For PR creation use pr-creator; for diff review use pr-reviewer; for npm releases use autoship.
Writes or rewrites a project's README.md tailored to its type (CLI, library, app, framework, monorepo, or skill bundle). Discovers project context from manifests, dispatches on the detected type, writes section by section, and validates against a quality checklist. Use when "write a README for this project", "create a README", "write a README from scratch", "rewrite this bad README", "bootstrap project documentation", or "the create-next-app README is still here". For auditing or improving an existing README or a docs site, use docs-writing. For AGENTS.md or CLAUDE.md agent-instruction files, use agents-md.
Scaffolds a production-ready TypeScript CLI and npm package with ESM, a dual tsdown build (CLI binary plus typed library), vitest, oxlint and oxfmt via ultracite, changesets, GitHub Actions CI with OIDC npm publishing, AGENTS.md, and a bundled agent skill definition. Use when creating a new CLI tool, bootstrapping a TypeScript package, scaffolding a node CLI, starting a new npm package, or asking "scaffold a CLI project" or "set up a new TypeScript CLI". For a Next.js web app use scaffold-nextjs; for structuring an existing codebase use define-architecture; for releasing an already-built package use autoship.
>- Audits built React and Next.js frontends for user-facing defects in code and failures, rollback gaps, stale async, accessibility markup, layout resilience, performance setup, typography, motion hazards, and microcopy. PR for UX bugs", "audit this component", "check my UI", "is this accessible", "design QA this page", or "is this ready to ship". For product decisions use product-design; for agentic apps use ax-audit; for deep type or motion use typography-audit or ui-animation; for the wording of a string rather than whether it is missing or leaky, use copywriting.
Scaffolds a production-ready Next.js turborepo end to end. Runs create-next-app with TypeScript 7, Tailwind CSS, React Compiler, and Cache Components, sets up shadcn/ui with Blode UI components from the Blode registry, blode-icons-react icons, Agentation, and Ultracite (Oxlint, Oxfmt, Lefthook), converts the app into a turborepo, then creates the GitHub repo and deploys to Vercel with a pre-launch checklist. Use when creating a brand-new Next.js app, bootstrapping a turborepo, scaffolding a web project, starting a new repo for a website or marketing site, or asking "create a Next.js project", "set up a turborepo", or "start a new web app". For a TypeScript CLI or npm package, use scaffold-cli. For folder structure and module contracts in an existing app, use define-architecture. For building a page inside an existing app, visual direction, palettes, and theming, use ui-design.
>- Fans out four concurrent review agents over the current diff, then APPLIES fixes directly to the working tree and verifies the build. Mutates code; it does not produce a report. Covers reuse (duplicate logic, hand-rolled stdlib, reinvented platform features), quality (hacky patterns, React/TypeScript hygiene, over-memoisation, exhaustive-deps, `any`, dead code, `CLAUDE.md`/`AGENTS.md` violations), efficiency (unnecessary work, missed concurrency, hot-path bloat), and test discipline (bug fixes without a repro test, useless tests to delete, missing tests only when they prevent a named failure). Use when the user says "tidy this up", "simplify", "clean up this diff", "polish my changes", "check for duplication", or "any reuse opportunities?", i.e. when the intent is to have the changes made automatically. For a read-only report that lists findings without touching files, use `pr-reviewer` instead. This skill edits code; for the PR's title, description, or commit history, use `pr-creator`.
Identifies dependencies at heightened risk of exploitation or takeover. Use when assessing supply chain attack surface, evaluating dependency health, or scoping security engagements.
