Use when working with repositories, commits, branches, merging, rebasing, worktrees, submodules, or multi-repo architectures. Includes parallel agent workflow patterns, merge strategies, conflict resolution, and large repo optimization. Triggers on git commands, version control, merge conflicts, worktree setup, submodule management, repository troubleshooting, branch strategy, rebase operations, cherry-pick decisions, and CI/CD git integration.
mcp-builder
Guide for creating MCP (Model Context Protocol) servers. Use this when building integrations with external services, creating new MCP servers, or connecting Claude to APIs.
mcp
Build MCP (Model Context Protocol) servers to extend Claude's capabilities with database access, API integrations, or custom tools.
mcp-builder
Guide for building high-quality Model Context Protocol (MCP) servers that allow LLMs to interact with external services. Use when creating new MCP integrations, tools, or servers for Claude or other AI systems.
lsp-enable
Use when navigating code, understanding unfamiliar functions, finding definitions or references, tracing call hierarchies, preparing for refactoring, or analyzing code impact. Enforces LSP-first semantic code intelligence with mandatory pre-edit checks, impact analysis before refactoring, and post-edit diagnostics. Provides IDE-like precision for code operations in large codebases. Covers navigation (goToDefinition, findReferences), understanding (hover, documentSymbol), and call analysis (incomingCalls, outgoingCalls).
extended-thinking
Extended thinking (ultrathink) configuration for Claude API. Activate for complex reasoning tasks, deep analysis, multi-step problem solving, and tasks requiring careful deliberation. Enables Claude's internal reasoning with configurable thinking budgets.
team-workflow
Deterministic team development workflow for Claude Code. Enforces a mandatory sequence of phases (Setup → Brainstorm → Plan → Execute → Quality Check → Ship) with Linear integration, TDD requirements, and quality gates. Activates when working on issues/tasks, when user mentions Linear issues (e.g., ENG-123), when starting development work, or when preparing to ship code. Commands: /team:task, /team:quality-check, /team:ship.
web-dev-skills
Use when working on web development tasks involving NextJS, React, TypeScript, Tailwind CSS, testing, deployment, APIs, databases, authentication, cloud infrastructure, or any modern web development stack. Provides access to 22 specialized web development skills covering frontend, backend, DevOps, and best practices.
anthropic-api
Integrates Anthropic Claude API for chat, tool use, and vision capabilities. Use when building AI-powered features with Claude models including streaming, extended thinking, and multi-turn conversations.
vercel-ai-sdk
Builds AI-powered applications with Vercel AI SDK including streaming responses, chat interfaces, and model integration. Use when integrating LLMs, building chat applications, streaming AI responses, or implementing AI features in React.
gh

uv-package-manager
Manage Python projects and dependencies using UV, the ultra-fast Rust-based package manager. Use when creating Python projects, managing dependencies, or running Python scripts.
github
★ 3.1kInteract with GitHub using the `gh` CLI. Use `gh issue`, `gh pr`, `gh run`, and `gh api` for issues, PRs, CI runs, and advanced queries.
networkx
★ 3.0kComprehensive toolkit for creating, analyzing, and visualizing complex networks and graphs in Python. Use when working with network/graph data structures, analyzing relationships between entities, computing graph algorithms (shortest paths, centrality, clustering), detecting communities, generating synthetic networks, or visualizing network topologies. Applicable to social networks, biological networks, transportation systems, citation networks, and any domain involving pairwise relationships.
shadcn-ui
★ 202shadcn/ui component library patterns. Covers CLI usage, installation, component categories, theming with CSS variables, dark mode setup, and integration with React Hook Form + Zod. Use when adding UI components, setting up design systems, or implementing forms with shadcn/ui.
