Claude Code & Cursor rules for claude-code

A three-agent content pipeline — a Writer that drafts, an Editor that rewrites for clarity and impact, and an SEO Optimizer that handles meta tags, keywords, and structure. For blog posts, documentation, and marketing pages.

A Model Context Protocol server that connects Claude Code to a PostgreSQL database. Exposes schema introspection, safe read queries, explain plans, and index suggestions as MCP tools. Write operations require explicit confirmation.

Pre-configured MCP server setup for PostgreSQL (query + migrate), Redis (cache management), GitHub (PRs + issues + actions), Sentry (error tracking + triage), and Vercel (deploy + env management). Complete JSON configs for Claude Code and Cursor with connection string templates, auth setup, permission scoping, and usage examples for each server.

Autonomous AI development loop for Claude Code with intelligent exit detection and rate limiting. Based on Geoffrey Huntley's Ralph Wiggum technique, it enables continuous autonomous development cycles where Claude Code iteratively improves your project until completion, with built-in safeguards to prevent infinite loops and API overuse.

Community-driven Claude Code best practices and CLAUDE.md patterns with 43K+ stars. Covers every Claude Code feature — subagents, commands, skills, hooks, MCP servers, plugins, settings, memory, workflows, and the Command-Agent-Skill orchestration pattern. Includes implemented examples, Boris Cherny's tips, and curated development workflow comparisons.

The most comprehensive toolkit for Claude Code — 135 agents, 35 curated skills (+400,000 via SkillKit), 42 commands, 176+ plugins, 20 hooks, 15 rules, 7 templates, 14 MCP configs, 26 companion apps, 52 ecosystem entries, and more. Over 850 files organized into a single installable collection.

A Claude Code skill for designing REST APIs — resource modeling, URL structure, HTTP method semantics, pagination, filtering, error responses, versioning, and OpenAPI spec generation. Forces contract-first design before implementation.

A Claude Code skill for generating high-quality tests — behavior-driven test structure, edge case discovery, mock strategy, and the test patterns that actually catch bugs. Supports Vitest, Jest, pytest, and Go testing.

A production SKILL.md for Claude Code that orchestrates four specialized agents in a structured code review and testing pipeline. The architect agent validates design decisions, the reviewer catches bugs, the test-writer generates comprehensive tests, and the security scanner finds vulnerabilities. Runs as a single /review-pipeline command with parallel execution and consolidated reporting.

A Claude Code skill that enforces systematic debugging — reproduce the bug, form a hypothesis, isolate the cause, fix with minimal change, and verify the fix doesn't break anything else. Triggers on error messages, stack traces, and 'it's broken' statements.

A Claude Code skill for performance optimization — profiling before optimizing, identifying real bottlenecks, database query optimization, frontend bundle analysis, caching strategies, and the common premature optimizations to avoid.

A two-agent team for Claude Code — a Developer agent that implements features, and a QA agent that immediately tests them. The QA agent writes tests, checks edge cases, runs accessibility audits, and files bugs before you ship. Coordinated handoff between agents.
