Claude Code Mastery

Complete skill for setting up, optimizing, and mastering Claude Code with a full development team of subagents.

Official Docs: https://code.claude.com/docs

---

⚡ Quick Check: Is Setup Complete?

Run this first:

command -v claude >/dev/null && echo "✅ Claude Code installed - SKIP to 'Daily Use' section" || echo "❌ Not installed - follow 'First-Time Setup' below"

If Claude Code is already installed, skip directly to the "Daily Use" section below.

---

🔧 FIRST-TIME SETUP (Skip if already installed)

> Note to bot: Only follow this section if Claude Code is NOT installed. Check with the command above. Once setup is complete, this section can be ignored on future invocations.

Setup Scripts

Run these in order:

cd ~/clawd/skills/claude-code-mastery/scripts

# 1. Check dependencies
./01-check-dependencies.sh

# 2. Install Claude Code
./02-install-claude-code.sh

# 3. Authenticate
./03-first-time-auth.sh

# 4. Install dev team subagents
./04-install-subagents.sh              # Starter pack (3 agents) - recommended
./04-install-subagents.sh --full-team  # All 11 agents

# 5. (Optional) Persistent memory - prompts y/N, default No
./05-setup-claude-mem.sh               # Interactive prompt
./05-setup-claude-mem.sh --skip        # Skip entirely
./05-setup-claude-mem.sh --yes         # Install without prompting

Configuration

Edit config.sh to customize:

• VALID_MODELS — Add models as Anthropic releases them
• HEARTBEAT_DIAGNOSTICS — Enable/disable in heartbeat (default: false)
• INSTALL_MODE — Default to "starter" or "full"

Setup Gotchas

| Issue | Solution | |-------|----------| | "Command not found" | Add ~/.local/bin to PATH | | Auth errors | Run ./03-first-time-auth.sh | | Slow startup | First run indexes codebase | | Subagents not showing | Run ./04-install-subagents.sh |

Post-Setup: Add Heartbeat Task

After setup, add the maintenance task to your HEARTBEAT.md (see "Heartbeat Maintenance" in Daily Use section).

Setup complete! Continue to Daily Use section.

---

📘 DAILY USE (Always relevant)

This section covers ongoing usage - reference this for all coding tasks.

Dev Team Subagents

Subagents are installed to ~/.claude/agents/. Each has a "Learn More" section with curated links to deepen expertise.

Starter Pack (Default) — 3 Core Agents

Most users only need these:

| Agent | Model | Purpose | |-------|-------|---------| | senior-dev | Sonnet | Architecture, complex code, code review | | project-manager | Sonnet | Task breakdown, timelines, dependencies | | junior-dev | Haiku | Quick fixes, simple tasks (fast & cheap) |

Install: ./04-install-subagents.sh (or --minimal)

Full Team (Optional) — All 10 Agents

For larger projects, install all 11 with --full-team:

| Agent | Model | Purpose | |-------|-------|---------| | senior-dev | Sonnet | Architecture, complex code, code review | | project-manager | Sonnet | Task breakdown, timelines, dependencies | | junior-dev | Haiku | Quick fixes, simple tasks (fast & cheap) | | frontend-dev | Sonnet | React, UI, CSS, client-side | | backend-dev | Sonnet | APIs, databases, server-side | | ai-engineer | Sonnet | LLM apps, RAG, prompts, agents | | ml-engineer | Sonnet | ML models, training, MLOps | | data-scientist | Sonnet | SQL, analysis, statistics | | data-engineer | Sonnet | Pipelines, ETL, data infrastructure | | product-manager | Sonnet | Requirements, user stories, prioritization | | devops | Sonnet | CI/CD, Docker, K8s, infrastructure, automation |

Using Subagents

Interactive mode: Use the /agent slash command or natural language:

/agent senior-dev
Use the senior-dev agent to review this code

Non-interactive mode (-p): Use the --agent flag:

claude --agent senior-dev -p "review this code for security issues"
claude --agent project-manager -p "create a task breakdown for auth feature"
claude --agent junior-dev -p "fix the typo in README.md"

Note: Claude Code does NOT auto-delegate to subagents based on task type. You must explicitly specify which agent to use.

Multi-agent handoff: For tasks needing multiple specialists, use HANDOFF.md to pass context between agents. See docs/workflows.md for the full pattern.

Quick Reference

CLI Commands

claude              # Start interactive
claude -c           # Continue previous session
claude -p "prompt"  # Non-interactive mode

Slash Commands

/agents   - Manage subagents
/clear    - Clear conversation (use between tasks!)
/compact  - Compress context
/model    - Change model
/help     - All commands

Keyboard Shortcuts

Shift+Tab - Toggle Plan mode (read-only exploration)
Ctrl+C    - Cancel operation
Ctrl+B    - Background task

---

Context Management (Critical!)

| Command | What it does | When to use | |---------|--------------|-------------| | /clear | Clear conversation, start fresh | Between unrelated tasks | | /compact | Summarize and compress context | When context getting full | | Shift+Tab | Toggle Plan mode (read-only) | Exploration before implementing |

Best practices:

1. /clear between unrelated tasks
2. Use Plan mode for exploration before implementing
3. Subagents isolate verbose operations
4. Create HANDOFF.md for session continuity

---

Project Configuration

settings.json

Create .claude/settings.json in your project:

{
  "model": "sonnet",
  "permissions": {
    "allow": ["Bash(npm:*)", "Bash(git:*)", "Read", "Write", "Edit"],
    "deny": ["Bash(rm -rf:*)", "Bash(sudo:*)"]
  }
}

CLAUDE.md

Create CLAUDE.md in your project root (Claude reads this automatically):

# Project: MyApp

## Tech Stack
- Frontend: React, TypeScript, Tailwind
- Backend: Node.js, PostgreSQL

## Commands
- `npm run dev` - Start dev server
- `npm test` - Run tests

See examples/CLAUDE-template.md for a full template.

---

Claude-Mem (If Installed)

Check status:

pgrep -f "worker-service" >/dev/null && echo "running" || echo "stopped"

Start if stopped:

cd ~/.claude/plugins/marketplaces/thedotmack && bun plugin/scripts/worker-service.cjs start

Web UI: http://localhost:37777

---

Diagnostics & Troubleshooting

Quick diagnostics:

~/clawd/skills/claude-code-mastery/scripts/06-diagnostics.sh

Full troubleshooting (if issues found):

~/clawd/skills/claude-code-mastery/scripts/08-troubleshoot.sh

Common issues guide: See docs/troubleshooting.md for solutions to:

• Authentication problems (API key, OAuth, logout bugs)
• Installation issues (PATH, WSL, Node.js version)
• Network errors (firewalls, VPNs, proxies)
• Performance problems (high CPU, hangs, slow search)

---

Heartbeat Maintenance

Add to your HEARTBEAT.md for automatic maintenance:

## Claude Code Maintenance

**Last Health Check:** [timestamp]
**Last Learning Session:** [timestamp]

### Every Heartbeat (if coding tasks active):
1. Quick claude-mem check (if installed):
   `pgrep -f "worker-service" >/dev/null && echo "running" || echo "stopped"`
   - Only restart if stopped
   - Note: pgrep saves ~500 tokens vs full status command

### Daily (morning):
1. Quick health check: `command -v claude && pgrep -f "worker-service"`
2. Only run full diagnostics if quick check fails

### Weekly (Sunday):
1. Run: `~/clawd/skills/claude-code-mastery/scripts/07-weekly-improvement-cron.sh`
2. Propose improvements (require human approval)
