jetbrains-coding
★ 2Use when JetBrains MCP tools are available (mcp__jetbrains__*) - enforces IDE-native workflow with problem checking after file completion, and smart refactoring tools instead of grep/sed
supabase-developer
★ 2Build full-stack applications with Supabase (PostgreSQL, Auth, Storage, Real-time, Edge Functions). Use when implementing authentication, database design with RLS, file storage, real-time features, or serverless functions.
maintaining-claude-code
★ 2Validate and improve Claude Code configurations (CLAUDE.md, skills, commands, hooks). Use when auditing config quality, checking skill discoverability, organizing .claude directory, or deciding which entity type to use.
mcp-server-development
★ 2Expert guidance for building MCP (Model Context Protocol) servers using the TypeScript SDK. Use when developing MCP servers, implementing tools/resources/prompts, or working with the @modelcontextprotocol/sdk package. Covers server initialization, request handlers, Zod schemas, error handling, and JSON-RPC patterns.
dart-flutter-mcp
★ 2Provides Flutter and Dart development workflows using dart-mcp tools. Triggers when working with .dart files, pubspec.yaml, or when user mentions Flutter, widget, Riverpod, Freezed, or Dart development. MUST BE USED for Flutter project work involving dart_analyzer, dart_run_tests, hot_reload, or IDE MCP tools.
ship-cli
★ 2Work management system replacing built-in todos with tracked tasks and stacked changes
git-safe-workflow
★ 2Safely inspect, stage, commit, and (only if asked) push changes made by an AI agent. Use for commit/push requests, end-of-task checkpoints, merge conflict resolution, worktree safety checks, or deciding whether to use git commit --amend.
gemini
★ 2Use when delegating tasks to Gemini MCP. Two main use cases: (1) large-scale codebase investigation with @ syntax, (2) web search for latest information. Also for long log analysis, context optimization. Always request concrete report format without omissions or personal opinions.
cidx
★ 2Code search and intelligence using CIDX. Use when searching codebases, finding implementations, tracing call graphs, analyzing dependencies, or searching git history. Preferred over grep/find for all code exploration.
artifacts-builder
★ 1Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts. | モダンなフロントエンドWeb技術（React、Tailwind CSS、shadcn/ui）を使用して、精巧なマルチコンポーネントclaude.ai HTMLアーティファクトを作成するツール群。状態管理、ルーティング、shadcn/uiコンポーネントが必要な複雑なアーティファクトに使用 - シンプルな単一ファイルHTML/JSXアーティファクトには不向き
context7
★ 1Fetch official documentation for major libraries and frameworks. Use for library lookups, API references, how-to queries, and framework-specific questions
makefile-assistant
★ 1Automatically capture Bash commands executed by Claude Code and convert them into documented, organized Makefile targets in .claude/makefiles/. Use when Claude executes any Bash command, when tempted to skip documentation ("too trivial", "one-time", "will do later"), or when user asks for Makefile generation. Process commands NOW while fresh, not later.
skill-builder
★ 1Create new Claude Code skills with best practices. Use when user wants to create, extract, or build a new skill. Provides templates and GitHub automation. Trigger phrases include "create a skill", "build a skill", "extract a skill", "new skill", "/skill-builder".
creating-mcp-servers
★ 1Creates production-ready MCP servers using FastMCP v2. Use when building MCP servers, optimizing tool descriptions for context efficiency, implementing progressive disclosure for multiple capabilities, or packaging servers for distribution.
slipstream-finetune
★ 1Finetune LLMs to speak Slipstream natively - complete guide with GLM-4-9B
pre-work-research
★ 1Use before starting implementation - research repository documentation, codebase patterns, and external resources to inform the approach
clean-commits
★ 1Use when committing code - ensures atomic, descriptive commits that leave the codebase in a merge-ready state at every point
branch-discipline
★ 1Use before any code changes - hard gate ensuring work never happens on main branch, with proper feature branch creation from correct base
skill-developer
★ 1Create and manage Claude Code skills following Anthropic best practices. Use when creating new skills, modifying skill-rules.json, understanding trigger patterns, working with hooks, debugging skill activation, or implementing progressive disclosure. Covers skill structure, YAML frontmatter, trigger types (AI-powered intent analysis, keyword matching), enforcement levels (validation only), hook mechanisms (UserPromptSubmit with auto-injection), session tracking, and the 500-line rule.
mcp-narsil
★ 1Deep code intelligence via Narsil MCP providing 76 tools for security scanning (OWASP, CWE, taint analysis), call graph analysis (CFG, DFG, callers/callees), structural queries (symbols, definitions, references), and supply chain security (SBOM, license compliance). Accessed via Code Mode for token efficiency.
initialize-repository
★ 1Meta-skill (Phase 0) for bootstrapping new repositories withworkflow system. Interactive callable tool that copies skills,documentation, and standards from source repository.Use when: Starting a new project that needs the workflow systemTriggers: "initialize new repository", "bootstrap workflow","replicate workflow system"
creating-agentic-commands
★ 1Create custom slash commands for workflow automation in OpenCode. Use when creating commands, automating workflows, or when user mentions slash commands, custom commands, /command patterns, or workflow automation.
moai-foundation-claude
★ 1Canonical Claude Code authoring kit covering Skills, sub-agents, plugins, slash commands, hooks, memory, settings, sandboxing, headless mode, and advanced agent patterns. Use when creating Claude Code extensions or configuring Claude Code features.
merge-conflict-resolution
