Why CC-Best?

🎯 The Problem: Claude Code is powerful, but configuring workflows, coding standards, and safety rules from scratch takes hours.

✨ The Solution: Pre-configured roles (PM → Lead → Designer → Dev → QA) that mirror real team collaboration, with safety guardrails built-in.

⚡ Quick Start

# Add marketplace and install
/plugin marketplace add xiaobei930/cc-best
/plugin install cc-best@xiaobei930

# Verify installation (30 seconds)
/cc-best:status

# Start using
/cc-best:iterate "implement user authentication"

💡 Enable Hooks: After installation, run /cc-best:setup --hooks to activate safety guards and automation hooks. See Hooks Configuration for details.

Plugin vs Clone: Command Format

Installation	Command format	Example
Plugin ⭐	/cc-best:command	/cc-best:iterate "add feature"
Clone	/command	/iterate "add feature"

💡 Recommended: Install via plugin for automatic updates and easier management. All documentation uses plugin format (/cc-best:xxx). Clone users: run convert-to-local.js.

<p align="center"> <img src="assets/setup.gif" alt="Setup Demo" width="80%"> </p> <details> <summary>📦 Alternative: Clone for full customization</summary>

git clone https://github.com/xiaobei930/cc-best.git .claude
cd .claude && bash scripts/shell/init.sh

# Convert command format from /cc-best:xxx to /xxx
node scripts/node/convert-to-local.js

Use clone when you need to customize all files in your repo.

⚠️ Important: All documentation uses plugin format (/cc-best:xxx). Run the conversion script to update to local format (/xxx).

</details> <details> <summary>🗑️ Uninstall</summary>

# Remove the plugin
/plugin uninstall cc-best@xiaobei930

# Remove marketplace (optional)
/plugin marketplace remove xiaobei930/cc-best

No files are left behind.

</details>

What Happens Next?

After running /cc-best:iterate "implement user authentication", Claude will:

1. 📋 /cc-best:pm     → Analyze requirements, create task breakdown
2. 🏗️ /cc-best:lead   → Design technical solution
3. 💻 /cc-best:dev    → Write code, create tests
4. 🧪 /cc-best:qa     → Run tests, verify quality
5. ✅ /cc-best:commit → Commit changes with proper message

You just watch. Intervene only when needed.

Common Workflows

I want to...	Command	What Claude does
Build a feature	/cc-best:iterate "add dark mode toggle"	Full cycle: plan → code → test → commit
Fix a bug	/cc-best:iterate "fix login timeout issue"	Investigate → fix → verify → commit
Review code	/cc-best:pm "review recent changes"	Analyze code, suggest improvements
Learn the codebase	/cc-best:pair	Step-by-step exploration with explanations

Who Is This For?

You are...	Recommended mode	Why
Team with multiple roles	Full workflow	PM → Lead → Dev → QA mirrors your process
Solo developer	/cc-best:iterate	Let Claude handle the boring parts
Learning Claude Code	/cc-best:pair	Understand each step before proceeding
Need quick fixes	Direct commands	/cc-best:dev "fix the typo" for simple tasks

---

✨ Core Features

Feature	What it does
🎭 Role-Based Workflow	PM → Lead → Designer → Dev → QA — complete development cycle
🔄 Autonomous Mode	/cc-best:iterate runs tasks without intervention until completion
🛡️ Safety Hooks	Blocks rm -rf /, git push --force, and other risky commands
📐 Multi-Language Standards	8-dir layered structure: common + Python/frontend/Java/C#/C++/embedded/UI rules
🧠 Memory Bank	Persists progress and decisions across sessions
👥 Pair Programming	/cc-best:pair — step-by-step collaboration with 5 confirmation checkpoints
🔗 Knowledge Pipeline	observe → analyze → learn → evolve — self-improving knowledge loop
🌐 Cross-Platform	Windows, macOS, Linux — auto-detects package manager

While CC-Best is built for Claude Code, the methodology (Dao-Fa-Shu-Qi) and role-driven patterns are framework-agnostic and can be adapted for other AI coding assistants.

What Makes CC-Best Different

<details> <summary><strong>🎭 Role-Driven Development Pipeline</strong></summary>

Not just a prompt template collection — CC-Best simulates real team collaboration:

• 7 roles with clear boundaries: PM → Lead → Designer → Dev → QA → Verify → Commit
• Each role has explicit MUST/SHOULD/NEVER rules, output templates, and handoff protocols
• Automatic flow: PM creates REQ → Lead reviews & creates DES/TSK → Dev implements → QA validates
• Downstream correction (A3): Lead can adjust PM decisions; QA distinguishes implementation bugs from requirement assumption errors
• Document traceability: REQ-XXX → DES-XXX → TSK-XXX numbered chain

</details> <details> <summary><strong>🔄 Autonomous Iteration Engine</strong></summary>

/cc-best:iterate enables fully autonomous development:

Read progress.md → Select role → Execute → Verify → Commit → Next task (no waiting)

• Smart role selection: 8 state conditions determine which role activates
• A1-A5 decision principles: Context inference (A1), decision recording (A2), downstream correction (A3), MVP fallback (A4), issue classification (A5)
• 4 strict stop conditions: All tasks done, user interrupt, fatal error, external dependency
• Cross-session continuity: memory-bank + progress.md rolling window

</details> <details> <summary><strong>🔗 Self-Evolving Knowledge Pipeline</strong></summary>

CC-Best learns from your development patterns:

observe → analyze → learn → evolve

• observe: observe-patterns.js hook automatically tracks tool usage patterns
• analyze: /cc-best:analyze mines git history and usage data
• learn: /cc-best:learn extracts reusable knowledge
• evolve: /cc-best:evolve generates new commands, skills, or agents from learned patterns

Stop conditions: All tasks done | User interrupt (Ctrl+C) | Fatal error | External dependency needed.

</details> <details> <summary><strong>How /cc-best:pair collaboration works</strong></summary>

5 mandatory confirmation checkpoints:

Checkpoint	Example
Understanding	"I understand you need X. Correct?"
Design choice	"Option A or B? I recommend A because..."
Destructive action	"About to delete X. Confirm?"
External call	"Will call production API. Proceed?"
Commit	"Commit message: '...'. OK?"

Learning mode: /cc-best:pair --learn "teach me unit testing" — Claude explains every step in detail.

Safe autonomy: Even in pair mode, Claude can freely read files, search code, run tests, and format code.

</details>

📖 Detailed usage guide: See MODES.md for comprehensive documentation on each mode, including when to use, how to control, and best practices.

Configuring Hooks

Edit .claude/settings.local.json:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "python scripts/your-script.py",
            "timeout": 5
          }
        ]
      }
    ]
  }
}

Pre-configured Hooks

⚠️ Important: Hooks Require Manual Setup

Due to a known Claude Code issue, plugin hooks are disabled by default. To enable the safety guards and automation hooks, run:

/cc-best:setup --hooks

This command configures hooks with absolute paths. See the FAQ for more details.

All hooks default to Node.js for cross-platform compatibility. Python/Bash alternatives available in scripts/.

Trigger	Function	Script (Node.js)
PreToolUse	Validate dangerous commands	validate-command.js
PreToolUse	Confirm before git push	pause-before-push.js
PreToolUse	Protect sensitive files	protect-files.js
PreToolUse	Block random .md creation	block-random-md.js
PreToolUse	Long-running task warning	long-running-warning.js
PostToolUse	Auto-format code	format-file.js
PostToolUse	Check console.log	check-console-log.js
PostToolUse	TypeScript type check	typescript-check.js
SessionStart	Session health check	session-check.js
PreCompact	Save state before compact	pre-compact.js

💡 Best Practices

1. Keep CLAUDE.md Concise

• Keep it under 100 lines
• Put detailed specifications in rules/

2. Use the Memory Bank

• Update progress.md after each task completion
• Record important decisions in architecture.md

3. Context Management

• Normal mode: Use /clear frequently to avoid context overflow
• /cc-best:iterate mode: Don't clear manually, maintain loop continuity

4. Don't Overload MCP

• Enable no more than 10 MCP servers per project
• Use disabledMcpServers to disable unused ones

5. Regular Cleanup

• Delete unused language rules
• Remove unused commands

6. MCP Temporary Directory Management

MCP tools auto-create temporary directories in your project:

Directory	Source	Purpose
.playwright-mcp/	MCP auto-created	Playwright MCP temporary files
.claude/mcp-data/	MCP auto-created	MCP shared data
*-mcp/	MCP auto-created	Other MCP tool directories
.claude/screenshots/	Template-defined	Manually saved screenshots (meaningful)

Cleanup Script: Use cleanup.sh for regular maintenance:

# Preview files to delete (dry run)
bash scripts/shell/cleanup.sh --dry-run

# Clean files older than 7 days (default)
bash scripts/shell/cleanup.sh

# Clean files older than 3 days
bash scripts/shell/cleanup.sh --days 3

# Clean all MCP temporary files
bash scripts/shell/cleanup.sh --all

❓ FAQ

📖 Full FAQ: See FAQ.md for comprehensive troubleshooting guides.

Quick Answers

<details> <summary><strong>Hooks not working?</strong></summary>

Run /cc-best:setup --verify to diagnose. Common fixes:

• Clone users: cp .claude/settings.local.json.example .claude/settings.local.json
• Plugin users: Run /cc-best:setup --hooks to configure absolute paths
• Windows: See FAQ.md for ${CLAUDE_PLUGIN_ROOT} workarounds

</details> <details> <summary><strong>/cc-best:iterate vs /pair?</strong></summary>

Mode	Control	Use Case
/cc-best:iterate	Fully autonomous	Clear task list
/cc-best:pair	Confirm each step	Learning, sensitive ops

</details> <details> <summary><strong>How to stop /iterate?</strong></summary>

• Interrupt: Press Ctrl+C (or Esc in some terminals)
• Pause: Type anything — Claude will wait for your input
• Resume: Just continue the conversation

Claude saves progress to memory-bank/progress.md, so you can always resume later.

</details> <details> <summary><strong>What if /cc-best:qa fails?</strong></summary>

Claude will:

1. Analyze the failure
2. Return to /cc-best:dev to fix the issue
3. Re-run /cc-best:qa to verify

If stuck after 3 attempts, Claude will ask for your input. You can:

• Provide hints: "Try checking the database connection"
• Skip the test: "Skip this test for now"
• Take over: "I'll fix this manually"

</details> <details> <summary><strong>MCP configuration?</strong></summary>

Edit .claude/settings.local.json:

{ "enabledMcpjsonServers": ["memory", "sequential-thinking"] }

Best practice: Enable ≤10 MCP servers per project.

</details> <details> <summary><strong>CC-Best vs Superpowers?</strong></summary>

Both are excellent. Choose based on your needs:

Scenario	Recommended	Why
Team collaboration	CC-Best	Role workflow (PM→Lead→Dev→QA)
Multi-language stack	CC-Best	7 language coding standard dirs
Chinese team	CC-Best	Bilingual docs
Solo developer	Superpowers	Lighter, git worktree automation
Need git worktree	Superpowers	Auto-creates isolated branches

💡 They can coexist! Use CC-Best for workflows, Superpowers for git automation.

</details>

🔧 Requirements

Dependency	Version	Notes
Claude Code	Latest recommended	Hooks require recent versions
Node.js	16+	For cross-platform hooks (default)
Python	3.8+	For some hook scripts
Bash/Git Bash	Any version	Optional for bash hooks

Optional MCP Servers

Some commands use MCP (Model Context Protocol) tools for enhanced functionality:

MCP Server	Used By	Purpose
Playwright	/cc-best:designer, /cc-best:dev, /cc-best:pm	Browser automation for UI testing and screenshots
Firecrawl	/cc-best:pm, /cc-best:lead	Web scraping for requirement research

Note: These are optional. Commands work without MCP servers but with reduced functionality. Install via Claude Code settings: Settings > MCP Servers

Supported Languages

Language	Rule File	Formatter	Test Framework
Python	python-style.md	Black + isort	pytest
Vue/TS/JS	frontend-style.md	Prettier	Vitest
C++	cpp-style.md	clang-format	Google Test
Java	java-style.md	google-java-format	JUnit
C#	csharp-style.md	dotnet format	xUnit/NUnit
Go	backend/go.md	gofmt	testing
Swift	native/ios.md	swift-format	XCTest

🌐 Note on Internal Files

CC-Best's internal files (commands/, rules/, skills/) are written in Chinese. This is intentional:

• Claude understands Chinese - All Claude models can read and follow Chinese instructions perfectly
• No translation burden - Maintaining dual-language internal files would be impractical
• Focus on users - The README (this file) is fully English for international users

If you prefer English internal files, community contributions for English translations are welcome!
