Compatible with Claude Code, Cursor, Codex, OpenCode, Gemini, and other AI Agent frameworks.

Core Features

• Agents (Subagents): 36+ specialized subagents for delegated tasks like code review, security analysis, build fixes, E2E testing, and more
• Skills: 183 workflow definitions and domain knowledge covering frontend, backend, testing, security, deployment, etc.
• Commands: 79 Legacy slash command compatibility layer, such as /tdd, /plan, /code-review
• Hooks: Event-based automation triggers for auto-formatting, security detection, memory persistence
• Rules: Cross-language always-follow guidelines, organized by language directory
• MCP Configuration: Pre-configured MCP servers (GitHub, Supabase, Vercel, etc.)

cp -r everything-claude-code/rules/common ~/.claude/rules/
cp -r everything-claude-code/rules/typescript ~/.claude/rules/  # Choose as needed

mkdir -p .claude/rules
cp -r everything-claude-code/rules/common .claude/rules/

Common Workflows

Starting a New Feature

/ecc:plan "Add user authentication with OAuth"
→ planner creates implementation blueprint
/tdd → tdd-guide enforces test-first approach
/code-review → code-reviewer checks your code

Fixing a Bug

/tdd → tdd-guide: Write a failing test that reproduces the bug
→ Implement the fix, verify test passes
/code-review → code-reviewer: Catch regression issues

Preparing for Launch

/security-scan → security-reviewer: OWASP Top 10 audit
/e2e → e2e-runner: Critical user flow testing
/test-coverage → Verify 80%+ coverage

Dashboard GUI

Launch the desktop dashboard to visually browse ECC components:

npm run dashboard
# or
python3 ./ecc_dashboard.py

Features: Tabbed interface (Agents, Skills, Commands, Rules, Settings), dark/light theme toggle, font customization, search filtering.
