laravel-11-12-app-guidelines
★ 16Guidelines and workflow for working on Laravel 11 or Laravel 12 applications across common stacks (API-only or full-stack), including optional Docker Compose/Sail, Inertia + React, Livewire, Vue, Blade, Tailwind v4, Fortify, Wayfinder, PHPUnit, Pint, and Laravel Boost MCP tools. Use when implementing features, fixing bugs, or making UI/backend changes while following project-specific instructions (AGENTS.md, docs/).
fetch-library-docs
★ 15Fetches official documentation for external libraries and frameworks (React, Next.js, Prisma, FastAPI, Express, Tailwind, MongoDB, etc.) with 60-90% token savings via content-type filtering. Use this skill when implementing features using library APIs, debugging library-specific errors, troubleshooting configuration issues, installing or setting up frameworks, integrating third-party packages, upgrading between library versions, or looking up correct API patterns and best practices. Triggers automatically during coding work - fetch docs before writing library code to get correct patterns, not after guessing wrong.
code-flow-tracer
★ 15Trace code execution paths and data flow. Use when user asks "how does X work", "what happens when X", "trace the flow of X", "where does data come from", or needs to understand feature implementation.
ailang-sprint-executor
★ 13Execute approved sprint plans with test-driven development, continuous linting, progress tracking, and pause points. Use when user says "execute sprint", "start sprint", or wants to implement an approved sprint plan.
oauth-implementation
★ 9OAuth 2.0 and OpenID Connect authentication with secure flows. Use for third-party integrations, SSO systems, token-based API access, or encountering authorization code flow, PKCE, token refresh, scope management errors.
nuxt-content
★ 9Nuxt Content v3 Git-based CMS for Markdown/MDC content sites. Use for blogs, docs, content-driven apps with type-safe queries, schema validation (Zod/Valibot), full-text search, navigation utilities. Supports Nuxt Studio production editing, Cloudflare D1/Pages deployment, Vercel deployment, SQL storage, MDC components, content collections.
workers-runtime-apis
★ 9Cloudflare Workers Runtime APIs including Fetch, Streams, Crypto, Cache, WebSockets, and Encoding. Use for HTTP requests, streaming, encryption, caching, real-time connections, or encountering API compatibility, response handling, stream processing errors.
cloudflare-sandbox
★ 9Cloudflare Sandboxes SDK for secure code execution in Linux containers at edge. Use for untrusted code, Python/Node.js scripts, AI code interpreters, git operations.
cloudflare-mcp-server
★ 9Build MCP (Model Context Protocol) servers on Cloudflare Workers with tools, resources, and prompts.
cloudflare-agents
★ 9Build AI agents on Cloudflare Workers with MCP integration, tool use, and LLM providers.
revenuecat
★ 8Comprehensive assistance with RevenueCat in-app subscriptions and purchases
pytorch-ml
★ 8Deep learning with PyTorch - model training, GPU acceleration, and data science workflows
mcp-builder
★ 8Guide 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).
create-slash-command
★ 8Create custom slash commands for Claude Code. Use when the user wants to create, add, or build a new slash command, custom command, or save a prompt as a command.
building-mcp-server-on-cloudflare
★ 6Builds remote MCP (Model Context Protocol) servers on Cloudflare Workerswith tools, OAuth authentication, and production deployment. Generatesserver code, configures auth providers, and deploys to Workers.Use when: user wants to "build MCP server", "create MCP tools", "remoteMCP", "deploy MCP", add "OAuth to MCP", or mentions Model Context Protocolon Cloudflare. Also triggers on "MCP authentication" or "MCP deployment".
mcp-chrome-devtools
★ 6This skill provides guidance for using Chrome DevTools MCP for browser debugging and automation. Use when debugging web pages, analyzing performance, inspecting network requests, viewing console messages, or interacting with Chrome DevTools features programmatically.
literate-programming
★ 5CRITICAL: ALWAYS activate this skill BEFORE making ANY changes to .nw files. Use proactively when: (1) creating, editing, reviewing, or improving any .nw file, (2) planning to add/modify functionality in files with .nw extension, (3) user asks about literate quality, (4) user mentions noweb, literate programming, tangling, or weaving, (5) working in directories containing .nw files, (6) creating new modules/files that will be .nw format. Trigger phrases: 'create module', 'add feature', 'update', 'modify', 'fix' + any .nw file. Never edit .nw files directly without first activating this skill to ensure literate programming principles are applied. (project, gitignored)
uv-package-manager
★ 5Manage Python projects and dependencies using UV, the ultra-fast Rust-based package manager. Use when creating Python projects, managing dependencies, or running Python scripts.
extension-create
★ 5Creates 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.
queue-worker
★ 5Bull queue setup, worker processes, job lifecycle, error handling, retries, progress reporting, Redis connection management, and queue patterns for OCR and knowledge processing
ha-emby-issue-executor
★ 5Use when implementing fixes or features from GitHub issues - autonomous execution with TDD, memory persistence, code review, and branch management. Works until issue complete or blocked.
symbols
★ 5Token-efficient codebase navigation through intelligent symbol loading and querying. Use this skill when implementing new features (find existing patterns), exploring codebase structure, searching for components/functions/types, or understanding architectural layers. Reduces token usage by 60-95% compared to loading full files. Layer split enables 50-80% additional backend efficiency.
julia-numerical
★ 5Execute numerical calculations and mathematical computations using Julia. Use this skill for matrix operations, linear algebra, numerical integration, optimization, statistics, and scientific computing tasks.
git-manager
★ 5Commit implementation changes to git with interactive branch selection and push confirmation. Use after completing implementation tasks, when all TODOs are marked complete, or when user requests to commit changes.
