Core Component Details

1. Agents (Sub-agents)

Agents are sub-agents that handle specific tasks, each with a clear scope of responsibility:

Typical Agents:

• code-reviewer: Code review agent focused on code quality, security, and maintainability
• test-writer: Test writing agent following TDD principles
• refactor-assistant: Refactoring assistant to help clean up code
• build-fixer: Build error fixing agent

Agent structure example:

---
name: code-reviewer
description: Reviews code for quality, security, and maintainability
tools: Read, Grep, Glob, Bash
model: opus
---

You are a senior code reviewer...

Design characteristics:

• Each agent focuses on a single responsibility
• Can specify which tools and models to use
• Supports tool restrictions to avoid overuse

2. Skills (Workflows)

Skills define reusable workflows that can be called by commands or agents:

Typical Skills:

• TDD workflow: Define interface → Write failing tests → Implement code → Refactor
• Code review process: Security check → Quality check → Performance check
• Refactoring process: Identify issues → Create plan → Gradually refactor → Validate

Design characteristics:

• Workflows are reusable
• Supports combination and nesting
• Can be parameterized

3. Hooks (Event Triggers)

Hooks automatically trigger operations based on tool usage events, enabling automation:

Typical Hooks:

• PreToolUse: Execute before tool use (e.g., check permissions)
• PostToolUse: Execute after tool use (e.g., log records)
• Stop: Execute when session stops (e.g., save state)

Hook configuration example:

{
  "matcher": "tool == \"Edit\" && tool_input.file_path matches \"\\\\.(ts|tsx|js|jsx)$\"",
  "hooks": [{
    "type": "command",
    "command": "#!/bin/bash\ngrep -n 'console\\.log' \"$file_path\" && echo '[Hook] Remove console.log' >&2"
  }]
}

Design characteristics:

• Event-driven
• Supports conditional matching
• Can execute commands or scripts

4. Commands

Commands are executable command collections providing quick access to common features:

Typical Commands:

• /build-fix: Fix build errors
• /refactor-clean: Clean up dead code
• /learn: Extract patterns from sessions
• /checkpoint: Save validated state
• /verify: Run validation loops

Design characteristics:

• Command-based interface, easy to use
• Can call agents and skills
• Supports parameter passing

5. Rules

Rules are guiding principles that are always followed, ensuring consistent behavior:

Typical Rules:

• security.md: Enforce security checks (no hardcoded keys)
• coding-style.md: Coding standards (immutability, file organization)
• testing.md: Testing requirements (TDD, 80% coverage)
• git-workflow.md: Git workflow (commit format, PR process)

Design characteristics:

• Modular, easy to manage
• Always in effect
• Can be customized per project

6. MCPs (Model Context Protocol)

MCPs provide integration with external tools and services:

Pre-configured MCPs:

• GitHub: Code repository operations
• Supabase: Database operations
• Vercel: Deployment service
• Railway: Cloud platform service

Design characteristics:

• Unified external service interface
• Supports multiple services configured simultaneously
• Can be enabled/disabled on demand

Key Technical Implementation

1. Context Window Management

Problem: Enabling too many MCPs can reduce the context window from 200k to 70k

Solution:

• Configure 20-30 MCPs but only enable 10 or fewer
• Use disabledMcpServers in project configuration to disable unused ones
• Keep active tools below 80

Best practice:

{
  "disabledMcpServers": ["unused-service-1", "unused-service-2"]
}

2. Modular Configuration

Design philosophy: Each component can be used independently, supporting on-demand combination

Implementation:

• Uses standard file structure
• Supports project-level and user-level configurations
• Provides clear configuration priorities

3. Cross-platform Scripts

Problem: Script execution differs across platforms

Solution:

• Use Node.js to write cross-platform scripts
• Provide unified tool interface (lib/utils.js)
• Auto-detect package managers (lib/package-manager.js)

Extension Mechanisms

1. Adding Custom Agents

Create a new agent file:

---
name: my-custom-agent
description: My custom agent for specific tasks
tools: Read, Edit
model: sonnet
---

You are a custom agent...

2. Adding Custom Hooks

Add to hooks.json:

{
  "matcher": "your condition",
  "hooks": [{
    "type": "command",
    "command": "your command"
  }]
}

3. Adding Custom Commands

Create a command file:

# my-command
description: My custom command
---

Workflow for my command...
