Development Claude Skills
8 673 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 1 239 copies of these same skills sitting in other people's repositories — counted once here, not 1 239 times.

Export a claude.ai (Claude Desktop / web) conversation and convert it to a Claude Code CLI JSONL session so it becomes resumable via `claude -r <sessionId>`. Use when the user wants to: (1) continue a claude.ai/Claude Desktop chat in Claude Code CLI, (2) import a web conversation into CC, (3) archive a claude.ai conversation locally with images and attachments, (4) unfreeze a claude.ai chat that hit its context limit, or (5) convert conversation.json from the claude.ai API to CC's JSONL envelope format. Triggers on mentions of exporting/importing Claude Desktop chats, resuming a web chat in CLI, conversation.json → JSONL, or claude.ai chat archival.
Restart the current Claude Code CLI in its own terminal (iTerm2 window or tmux pane) and resume a session — the external relaunch step an agent cannot perform on itself. Use when: (1) the session's context is nearly full and was just stripped in place with session-stripper, so the CLI must restart to load the smaller transcript, (2) resuming a forked stripped session under a new session id, (3) the user or the agent says respawn, restart yourself, restart the CLI, reload the session, or resume after strip. Backends: iTerm2 (macOS) and tmux (works headless, e.g. Linux servers).
Build a complete mental map of a project through phased exploration so you can work effectively without rediscovering things. Use when the user wants to: (1) Onboard onto a new or unfamiliar codebase, (2) Get a full project overview or briefing, (3) Understand project architecture, structure, and open work, (4) Initialize context at the start of a deep work session, (5) Explore and summarize a repository end-to-end. Triggers on requests like \"explore this repo\", \"get familiar with this project\", \"give me a project overview\", \"onboard me\", \"init context\", or any request to deeply understand a codebase before working on it.
Pack repositories with Repomix for whole-codebase, cross-file analysis. Default to a whole-repo measurement pass, then a filtered whole-repo pack; if it fits under ~1M tokens, stop and hand off to Gemini. Only if it doesn’t fit after the initial noise filter, reduce scope at folder granularity (avoid file-by-file selection), then iterate based on Gemini feedback.
Comprehensive ImageMagick 7 command-line image processing for inspecting, converting, resizing, cropping, compositing, masking, drawing, annotating, color correction, quantization, filtering, morphology, distortion, animation, montage, comparison, metadata, batch automation, and advanced pixel analysis. Use whenever a task mentions ImageMagick, `magick`, `identify`, `mogrify`, raster image conversion or batch image manipulation, or when a reproducible CLI pipeline is preferable to a GUI or language binding. Also use for debugging ImageMagick commands, porting ImageMagick 6 `convert` syntax to version 7, choosing coder/delegate options, and safely processing untrusted or large images. Do not use merely to edit an existing SVG as vector source or when the user explicitly requests a different image tool.
Enforce OOP and DDD engineering constraints for C# and TypeScript game development. Use when implementing, refactoring, reviewing, or verifying gameplay systems, domain-controlled engine-view wrappers, domain models, aggregates, application services, repositories, public APIs, or Context-based shared dependencies. Preserve encapsulation, avoid test-only production hooks, unit-test only engine-agnostic leaf logic, and verify integrated behavior by running the real engine.

Scaffold a new context-mill skill that walks an agent through an ordered series of narrowly-scoped reference files. Works for any number of steps. Use when the user wants to add a docs-only skill where the agent must read each step in strict order, one at a time, with each step isolated, with clear endpoints, and no prefetching.
Release moi-computer to npm — verify locally, hand off to the gated GitHub Actions workflow, then verify the published package. Defaults to a `next` preview; pass `stable` for a `latest` release. Use when the user asks to publish, release, ship a version, or cut a dev preview.
This skill should be used when writing Ruby gems following Andrew Kane's proven patterns and philosophy. It applies when creating new Ruby gems, refactoring existing gems, designing gem APIs, or when clean, minimal, production-ready Ruby library code is needed. Triggers on requests like "create a gem", "write a Ruby library", "design a gem API", or mentions of Andrew Kane's style.

Creates and reviews CLAUDE.md configuration files for Claude Code. Applies HumanLayer guidelines including instruction budgets (~50 user-level, ~100 project-level), WHAT/WHY/HOW framework, and progressive disclosure. Identifies anti-patterns like using Claude as a linter for style rules.
Use this agent when you need a final review pass to ensure code changes are as simple and minimal as possible. This agent should be invoked after implementation is complete but before finalizing changes, to identify opportunities for simplification, remove unnecessary complexity, and ensure adherence to YAGNI principles. Examples: <example>Context: The user has just implemented a new feature and wants to ensure it's as simple as possible. user: \"I've finished implementing the user authentication system\" assistant: \"Great! Let me review the implementation for simplicity and minimalism using the code-simplicity-reviewer agent\" <commentary>Since implementation is complete, use the code-simplicity-reviewer agent to identify simplification opportunities.</commentary></example> <example>Context: The user has written complex business logic and wants to simplify it. user: \"I think this order processing logic might be overly complex\" assistant: \"I'll use the code-simplicity-reviewer agent to analyze the complexity...
Use when writing, reviewing, or refactoring code. Apply when naming variables or functions, structuring classes, handling errors, writing tests, or when code feels complex or hard to understand. Based on Robert C. Martin's Clean Code.
Use this agent when you need a brutally honest Rails code review from the perspective of David Heinemeier Hansson. This agent excels at identifying anti-patterns, JavaScript framework contamination in Rails codebases, and violations of Rails conventions. Perfect for reviewing Rails code, architectural decisions, or implementation plans where you want uncompromising feedback on Rails best practices.\\n\\n<example>\\nContext: The user wants to review a recently implemented Rails feature for adherence to Rails conventions.\\nuser: \"I just implemented a new user authentication system using JWT tokens and a separate API layer\"\\nassistant: \"I'll use the DHH Rails reviewer agent to evaluate this implementation\"\\n<commentary>\\nSince the user has implemented authentication with patterns that might be influenced by JavaScript frameworks (JWT, separate API layer), the dhh-rails-reviewer agent should analyze this critically.\\n</commentary>\\n</example>\\n\\n<example>\\nContext: The user is planning a new Rails feature and wan...
Use this agent when you need to gather comprehensive documentation and best practices for frameworks, libraries, or dependencies in your project. This includes fetching official documentation, exploring source code, identifying version-specific constraints, and understanding implementation patterns. <example>Context: The user needs to understand how to properly implement a new feature using a specific library. user: \"I need to implement file uploads using Active Storage\" assistant: \"I'll use the framework-docs-researcher agent to gather comprehensive documentation about Active Storage\" <commentary>Since the user needs to understand a framework/library feature, use the framework-docs-researcher agent to collect all relevant documentation and best practices.</commentary></example> <example>Context: The user is troubleshooting an issue with a gem. user: \"Why is the turbo-rails gem not working as expected?\" assistant: \"Let me use the framework-docs-researcher agent to investigate the turbo-rails documentation...
This skill manages Git worktrees for isolated parallel development. It handles creating, listing, switching, and cleaning up worktrees with a simple interactive interface, following KISS principles.
Use this agent when you need to understand the historical context and evolution of code changes, trace the origins of specific code patterns, identify key contributors and their expertise areas, or analyze patterns in commit history. This agent excels at archaeological analysis of git repositories to provide insights about code evolution and development patterns. <example>Context: The user wants to understand the history and evolution of recently modified files.\\nuser: \"I've just refactored the authentication module. Can you analyze the historical context?\"\\nassistant: \"I'll use the git-history-analyzer agent to examine the evolution of the authentication module files.\"\\n<commentary>Since the user wants historical context about code changes, use the git-history-analyzer agent to trace file evolution, identify contributors, and extract patterns from the git history.</commentary></example> <example>Context: The user needs to understand why certain code patterns exist.\\nuser: \"Why does this payment processing...
Use this agent when you need to review Python code changes with an extremely high quality bar. This agent should be invoked after implementing features, modifying existing code, or creating new Python modules. The agent applies Kieran's strict Python conventions and taste preferences to ensure code meets exceptional standards.\\n\\nExamples:\\n- <example>\\n Context: The user has just implemented a new FastAPI endpoint.\\n user: \"I've added a new user registration endpoint\"\\n assistant: \"I've implemented the registration endpoint. Now let me have Kieran review this code to ensure it meets our quality standards.\"\\n <commentary>\\n Since new endpoint code was written, use the kieran-python-reviewer agent to apply Kieran's strict Python conventions and quality checks.\\n </commentary>\\n</example>\\n- <example>\\n Context: The user has refactored an existing service class.\\n user: \"Please refactor the EmailService class to handle attachments\"\\n assistant: \"I've refactored the EmailService to handle attachments.\"\\n <com...
Use this agent when you need to review TypeScript code changes with an extremely high quality bar. This agent should be invoked after implementing features, modifying existing code, or creating new TypeScript components. The agent applies Kieran's strict TypeScript conventions and taste preferences to ensure code meets exceptional standards.\\n\\nExamples:\\n- <example>\\n Context: The user has just implemented a new React component with hooks.\\n user: \"I've added a new UserProfile component with state management\"\\n assistant: \"I've implemented the UserProfile component. Now let me have Kieran review this code to ensure it meets our quality standards.\"\\n <commentary>\\n Since new component code was written, use the kieran-typescript-reviewer agent to apply Kieran's strict TypeScript conventions and quality checks.\\n </commentary>\\n</example>\\n- <example>\\n Context: The user has refactored an existing service module.\\n user: \"Please refactor the EmailService to handle attachments\"\\n assistant: \"I've refactored t...
