Everything Claude Code
The performance optimization system for AI agent harnesses. From an Anthropic hackathon winner. Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, hooks, commands, rules, and MCP configurations evolved over 10+ months of intensive daily use building real products. Works across Claude Code, Cursor, Codex, OpenCode, and other AI agent harnesses.This repo is the raw code only. The Shorthand Guide and Longform Guide explain everything.
Key Features
13 Specialized Agents
Production-ready agents for planning, architecture, TDD, code review, security, build fixing, E2E testing, refactoring, and documentation.
56+ Skills
Workflow definitions and domain knowledge covering coding standards, backend/frontend patterns, security, testing, continuous learning, and framework-specific best practices.
33 Commands
Slash commands for quick execution:
/plan, /tdd, /code-review, /build-fix, /e2e, /security-scan, /orchestrate, and more.Automated Hooks
Trigger-based automations for memory persistence, strategic compaction, security warnings, format-on-save, and session management.
Multi-Language Rules
Always-follow guidelines organized into common (language-agnostic) + language-specific directories for TypeScript, Python, Go, Swift, Java, and C++.
Cross-Platform
Full support for Windows, macOS, and Linux with automatic package manager detection (npm, pnpm, yarn, bun).
What’s Inside
Agents
14 specialized subagents handle delegated tasks with limited scope:- planner - Feature implementation planning

- build-error-resolver - Build and type error fixing
- e2e-runner - Playwright E2E testing
- refactor-cleaner - Dead code cleanup
- doc-updater - Documentation synchronization
- go-reviewer - Go code review
- go-build-resolver - Go build error resolution
- python-reviewer - Python code review (PEP 8, type hints, security)
- database-reviewer - Database/Supabase review
- chief-of-staff - Multi-agent orchestration

Hooks
Trigger-based automations:- Session lifecycle - Load/save context automatically
- Strategic compaction - Suggest compaction at logical breakpoints
- Security warnings - Detect hardcoded secrets, prevent credential commits
- Format-on-save - Auto-format TypeScript/Python/Go files
- Dev server guards - Block dev servers outside tmux
- Git push review - Reminder before pushing changes
Rules
Always-follow guidelines organized by language: Common (9 rules):- coding-style, git-workflow, testing, performance, patterns, hooks, agents, security
- TypeScript/JavaScript (7 rules)
- Python (5 rules)
- Go (4 rules)
- Swift (3 rules)
- Java (2 rules)
