Coding standards, frameworks, refactoring, and code review (15.1K skills)
Coordinate coding projects through Claude DevFleet by splitting work into dependent tasks and dispatching Claude Code agents in separate Git working directories. Monitor progress, manage automatic task sequencing, and review structured reports of changes, tests, and errors.
Explore an unfamiliar codebase and turn its structure, request flow, and development conventions into a concise onboarding guide. Create or update CLAUDE.md with project-specific instructions, preserving existing guidance and identifying findings that remain uncertain.
Review how easy code is to maintain using CodeScene MCP. Compare structural health scores before and after edits, identify design issues, and check commits and pull requests for changes that reduce maintainability.
Diagnose failed AI agent runs by capturing errors, checking likely causes, and choosing small, reversible recovery actions. The workflow produces a structured report of the failure, recovery steps, and evidence, helping explain repeated retries or stalled progress.
Build or review server-side APIs in Node.js, Express, and Next.js. Apply patterns for organizing business logic and data access, reducing unnecessary database queries, caching results, validating requests, and handling authentication and errors.
Design caching for repeated PDF parsing, text extraction, or image analysis using SHA-256 hashes, identifiers calculated from file contents. Reuse results after files move or change names, and process them again when their contents change.
Create CodeTour files that guide readers through a codebase step by step, with verified file and line references. Tailor the walkthrough to new contributors, architecture readers, PR reviewers, or investigators tracing a failure or security boundary.
Use Bun to run JavaScript and TypeScript, manage project dependencies, build applications, and run tests. Includes guidance for choosing between Bun and Node, migrating existing projects, and configuring deployments on Vercel.
Integrate x402, an HTTP payment protocol, so agents can pay for APIs or services. Configure task and session budgets, approved recipients, and wallets with privately managed keys, using integration paths for Base, X Layer, or Solana.
Plan autonomous Claude Code workflows, from sequential development steps to parallel agents working from a specification. The material explains how to preserve progress between runs, check quality, coordinate merges, and set limits that stop repeated execution.
Build shared interfaces for Android, iOS, Desktop, and Web with Compose. This skill guides screen state, navigation, reusable components, themes, and rendering performance, including ways to handle interface differences between platforms.
Access paid APIs using Machine Payments Protocol (MPP), a protocol for request payments. The skill checks payment requirements, selects a compatible wallet or client, submits payment, and helps inspect the API response and receipt.
Search and rewrite code by its syntax structure, such as function definitions or calls. Preview changes across files before applying them, and use YAML rules for repeatable checks and automatic fixes.
Test a plan before implementation through structured, challenging questions. Work through decisions in dependency order, receive recommendations with each question, and finish with a clear account of agreed choices, open issues, and scope.
Diagnose REST and GraphQL API failures by checking connectivity, authentication, request formats, and returned data. Prepare reproducible commands, identify likely causes, and build regression tests that check whether a fix keeps working.
Record a website's network traffic in a HAR file, a log of requests and responses, then derive an HTTP client from its JSON requests. Reuse captured request details to run searches or fetch data without repeated browser interaction.
Carry out an implementation plan by assigning each task to a fresh subagent, a separate agent with its own context. Review specification compliance first, then code quality, repeat fixes as needed, and finish with an integration review.
Add an AI assistant to an existing web app so users can operate its interface with everyday instructions. Covers embedding the panel, connecting a language model, testing interactions, and protecting API keys in production.
Turn code changes and system structure into animated SVG diagrams. The skill maps changed components, surrounding context, and ordered data flows, then helps prepare diagrams for sharing in pull requests or through an optional published link.
Turn a codebase into an interactive graph of code relationships. Explore functions, call chains, related groups, and execution flows in a browser, with optional Cloudflare tunneling to share the explorer remotely.
Build Python MCP servers that let AI agents use APIs, databases, and file workflows. MCP is a connection standard for agent tools. The skill covers starter templates, local testing, client registration, and deployment as HTTP endpoints.
Control the Unreal Engine editor to build scenes, place objects, adjust lighting and materials, and frame camera shots. The skill guides inspection, incremental edits, visual checks, saving, and producing screenshots or renders.
Helps you discover, authenticate, and call MCP servers from the terminal. MCP connects agents to external tools. You can inspect available tools, manage connections, make one-off calls, and generate command-line wrappers or TypeScript clients.
Generate an interactive bash script that guides people through manual service setup. It opens relevant pages, explains what to click, collects credentials, and saves values to .env files or GitHub secrets with stage confirmations.
