typescript-expert-2025
★ 2Expert TypeScript development patterns and tooling for December 2025. Use when (1) Setting up modern TypeScript projects with Bun, Node 22+, or Deno, (2) Configuring tsconfig, ESM/CJS dual publishing, or build tooling, (3) Implementing advanced type patterns like satisfies, as const, template literals, mapped types, (4) Choosing between Biome, Oxlint, or ESLint for linting, (5) Optimizing TypeScript performance, or any expert-level TypeScript architecture questions.
docs-seeker
★ 2Searching internet for technical documentation using llms.txt standard, GitHub repositories via Repomix, and parallel exploration. Use when user needs: (1) Latest documentation for libraries/frameworks, (2) Documentation in llms.txt format, (3) GitHub repository analysis, (4) Documentation without direct llms.txt support, (5) Multiple documentation sources in parallel
better-auth
★ 2Implement authentication and authorization with Better Auth - a framework-agnostic TypeScript authentication framework. Features include email/password authentication with verification, OAuth providers (Google, GitHub, Discord, etc.), two-factor authentication (TOTP, SMS), passkeys/WebAuthn support, session management, role-based access control (RBAC), rate limiting, and database adapters. Use when adding authentication to applications, implementing OAuth flows, setting up 2FA/MFA, managing user sessions, configuring authorization rules, or building secure authentication systems for web applications.
github-api-cache
★ 2MANDATORY before any GitHub project operations - caches project metadata to prevent rate limit exhaustion. Called by session-start. Other skills MUST use cached data.
ralph
★ 2Autonomous task loop that picks ready tasks, implements them in new threads, commits, and repeats. Use when asked to "ralph", "use a ralph loop", or "ralph this".
jules-delegation
★ 2Delegate complex coding tasks to Google's Jules autonomous AI coding agent. Use this skill when you need to offload time-consuming implementation work, create parallel coding sessions, or handle tasks that benefit from asynchronous execution.
android-use
★ 2This skill enables control of Android devices via ADB and the accessibility API. Use this skill when users want to automate Android phone tasks, control apps remotely, tap buttons, type text, navigate UI, or perform any action on a connected Android device. Requires ADB and a connected device with USB debugging enabled.
codebase-agent
★ 2Expert coding agent for this codebase. Learns from every session to improvecode quality, catch edge cases, and apply proven patterns. Use for ANY codingtask: writing, debugging, refactoring, testing. Accumulates project knowledge.
typescript-lsp
★ 2TypeScript Language Server Protocol capabilities for navigating TypeScript/JavaScript code. Resolves imported symbols to their definitions (including node_modules), finds all references to functions/classes/variables, gets type information and signatures, previews rename impacts, and checks TypeScript diagnostics. Use when you need to find where ToolLoopAgent or other imports are defined, locate all usages of a function, see TypeScript types, or get compiler errors.
dify-tool-developer
★ 2Guide AI agents through Dify tool plugin development with mandatory documentation loading and direct CLI usage. Use when creating Dify tool plugins or extending Dify with custom tools.
artifacts-builder
★ 2Suite 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.
claude-code-plugin-dev
★ 2Comprehensive guide for building, testing, and distributing Claude Code plugins including slash commands, Agent Skills, subagents, MCP servers, and hooks. Use this when the user asks about creating plugins, writing slash commands, implementing skills, building MCP tools, configuring hooks, plugin architecture, marketplace distribution, or debugging plugin components. Covers 2025 schema with tool permissions, version tracking, and activation triggers.
change-impact-analyzer
★ 2Determine what needs modification and identify potential side effects of changes. Use before implementing changes to understand full scope and prevent breaking existing functionality.
codebase-explorer
★ 2Identify relevant files, understand architecture patterns, and find code by functionality. Use when you need to understand where specific functionality lives or find files related to a feature area.
codebase-explorer
★ 2Deep codebase exploration using semantic search and relationship mapping. Use when you need to understand the current codebase.
skill-developer
★ 2Create 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 (keywords, intent patterns, file paths, content patterns), enforcement levels (block, suggest, warn), hook mechanisms (UserPromptSubmit, PreToolUse), session tracking, and the 500-line rule.
claude-code-plugin-builder
★ 2Creates Claude Code plugins with proper manifest structure, directory layout, and components (commands, agents, skills, hooks, MCP servers). Use when user requests creating plugins, adding slash commands, integrating MCP servers, setting up hooks, migrating Gemini extensions, or mentions "plugin.json", ".claude-plugin", or "marketplace.json". Handles plugin testing, debugging, and marketplace distribution.
adk
★ 2Build, debug, and ship agents with Google’s Agent Development Kit (ADK) — especially the Go SDK (google/adk-go). Trigger when users ask to create/modify ADK agents, tools, workflows, launcher configs, tests, evaluations, or MCP toolsets bridging ADK and external tools.
ast-grep
★ 2Structural code pattern search and refactoring using ast-grep (sg). Use for finding functions, classes, methods, imports, or any code structure patterns. Supports syntax-aware analysis across multiple languages including JavaScript, TypeScript, Python, Ruby, Go, Rust, and more. Use when searching for code patterns based on structure rather than plain text.
python-uv-dev
★ 2Python development using the `uv` package manager. Use this skill when working with Python projects that use `uv` for dependency management, when initializing new Python projects, or when the user mentions `uv`, `pyproject.toml`, or asks about Python package management best practices.
correct-git-commits-no-exceptions
★ 2Enforce mature commit hygiene and documentation standards for long-lived projects. Trigger this skill automatically in ANY project before ANY commit creation, whether prompted by human, agent, or another skill; always do this, to ensure changesets are clean, tests pass, commit messages are terse and insightful, and all committed content is timeless rather than dependent on circumstantial context to cohere or be useful. Targets senior/staff engineer standards - no cruft, no debug statements, no transient language, no obvious comments. Maintains README accuracy and prevents documentation bloat.
minecraft-fabric-dev
★ 2Comprehensive guidance for Minecraft mod development with Fabric, including porting from other mod loaders (Forge, NeoForge). Integrates MCP servers for decompilation, documentation access, and mixin validation. Use when developing Fabric mods, porting from Forge, or working with Minecraft source code.
