mcp-builder
★ 1Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK). | 適切に設計されたツールを通じてLLMが外部サービスと対話できるようにする高品質MCP（Model Context Protocol）サーバーを作成するためのガイド。Python（FastMCP）またはNode/TypeScript（MCP SDK）で外部APIやサービスを統合するMCPサーバーを構築する際に使用
github-tools
★ 1Executes GitHub operations via gh CLI wrapper. Use when managing issues, pull requests, workflows, CI runs, projects, releases, cache, labels, or searching repositories and code.
terminal-shell
★ 1Execute system commands on the server.
using-lsp-tools
★ 1Use when mcp-language-server tools are available and you need semantic code intelligence for navigation, refactoring, or type analysis
git
★ 1Git repository operations - status, diff, commit, branch, log. Converted from MCP server for 90%+ context savings.
cargo
★ 1Rust package manager (36 subcommands).
code-engineer-executor
★ 1Navigate, analyze, and modify codebases using LSP semantic navigation. Use when user needs code refactoring, bug fixing, feature implementation, code analysis. Returns structured code changes with LSP navigation metadata.
execute-code
★ 1Execute JavaScript or Python code in a secure Hyperlight VM sandbox with full isolation. Use this when users request running code, performing calculations, testing algorithms, or demonstrating code behavior with actual output.
github
★ 1GitHub API operations - repositories, issues, pull requests, actions, code security, discussions, gists, and more. Use for GitHub-related tasks like managing PRs, issues, searching code, and monitoring workflows.
work-issue
★ 1Core implementation logic for working on a single GitHub issue. Used by both /work command and /work-all subagents to ensure consistent behavior.
github-operations
★ 1Expert in GitHub workflows including issue management, PR operations, and branch conventions. Use when working with GitHub via MCP.
latest-docs
★ 1Fetch and verify latest official documentation before implementation. Use when implementing features with any library, framework, or technology. Prevents outdated patterns and deprecated API usage.
leta
★ 1Fast semantic code navigation via LSP. Load FIRST before ANY code task - even 'simple' ones. Trigger scenarios: (1) fixing lint/type/pyright/mypy warnings or errors, (2) fixing reportAny/reportUnknownType/Any type errors, (3) adding type annotations, (4) refactoring or modifying code, (5) finding where a function/class/symbol is defined, (6) finding where a symbol is used/referenced/imported, (7) understanding what a function calls or what calls it, (8) exploring unfamiliar code or understanding architecture, (9) renaming symbols across codebase, (10) finding interface/protocol implementations, (11) ANY task where you'd use ripgrep to find code or read-file to view a function. Use `leta show SYMBOL` instead of read-file, `leta refs SYMBOL` instead of ripgrep for usages, `leta grep PATTERN` instead of ripgrep for definitions, `leta files` instead of list-directory.
mcp-complete-guide
★ 1Complete 11-phase guide for building production-ready MCP (Model Context Protocol) servers with semantic layer integration. Covers foundation to deployment, including agent-centric design, tool development, testing, error handling, performance optimization, monitoring, security, governance, and semantic layer integration for business metrics. Use when building enterprise-grade MCP servers that integrate with dbt, Tableau, or other semantic layers for Finance SSC, business analytics, or data governance use cases.
fastmcp
★ 1Build MCP servers in Python with FastMCP framework to expose tools, resources, and prompts to LLMs. Supportsstorage backends (memory/disk/Redis), middleware, OAuth Proxy, OpenAPI integration, and FastMCP Cloud deployment.Use when: creating MCP servers, defining tools or resources, implementing OAuth authentication, configuringstorage backends for tokens/cache, adding middleware for logging/rate limiting, deploying to FastMCP Cloud,or troubleshooting module-level server, storage, lifespan, middleware order, circular imports, or OAuth errors.Keywords: FastMCP, MCP server Python, Model Context Protocol Python, fastmcp framework, mcp tools, mcp resources, mcp prompts, fastmcp storage, fastmcp memory storage, fastmcp disk storage, fastmcp redis, fastmcp dynamodb, fastmcp lifespan, fastmcp middleware, fastmcp oauth proxy, server composition mcp, fastmcp import, fastmcp mount, fastmcp cloud, fastmcp deployment, mcp authentication, fastmcp icons, openapi mcp, claude mcp server, fastmcp testing, storage misconf
git-workflow
★ 1Use when working with git operations - generates smart commit messages (present tense, imperative), manages branches, creates PRs with summaries, follows git best practices. Activates when user says "commit this", "create PR", "push changes", mentions "git", "branch", "merge", or before committing code.
ai-ml-engineer
★ 1Copilot agent that assists with machine learning model development, training, evaluation, deployment, and MLOpsTrigger terms: machine learning, ML, AI, model training, MLOps, model deployment, feature engineering, model evaluation, neural network, deep learningUse when: User requests involve ai ml engineer tasks.
github
★ 1Interact with GitHub repositories, issues, pull requests, and code via the GitHub MCP server. This skill should be used when managing repositories, creating/updating files, working with issues and PRs, searching code/repos/users, creating branches, and performing code reviews. Supports all major GitHub API operations.
mcp-builder
★ 1Guide for building MCP (Model Context Protocol) servers that integrate external APIs/services with LLMs. Covers Python (FastMCP) and TypeScript (MCP SDK) implementations.
copilot-mcp-server
★ 1Direct access to GitHub Copilot MCP server tools for AI-powered development assistance
pydantic
★ 1Python data validation using type hints and runtime type checking with Pydantic v2's Rust-powered core for high-performance validation in FastAPI, Django, and configuration management.
mypy
★ 1mypy - Static type checker for Python with gradual typing, strict mode, Protocol support, and framework integration
uv-package-manager
★ 1Master the uv package manager for fast Python dependency management, virtual environments, and modern Python project workflows. Use when setting up Python projects, managing dependencies, or optimizing Python development workflows with uv.
extension-create
★ 1Creates slash commands, subagents/workflows, or agent skills using the Claude request type framework. Analyzes requirements, determines the optimal extension type (command/subagent/skill), decides project vs personal scope, and generates properly structured files following templates and best practices. Use when creating new commands, workflows, or skills, or when the user mentions "create a command", "new workflow", "build a skill", or requests custom Claude Code extensions.
