|
|
vim CLAUDE.md
|
|
```
|
|
|
|
### Automation & Hooks
|
|
```bash
|
|
# Install hooks (25 events, 4 types: command, http, prompt, agent)
|
|
mkdir -p ~/.claude/hooks
|
|
cp 06-hooks/*.sh ~/.claude/hooks/
|
|
chmod +x ~/.claude/hooks/*.sh

|
|
```
|
|
|
|
### Complex Implementation
|
|
```bash

|
# Claude implements systematically
|
|
```
|
|
|
|
### CI/CD Integration
|
|
```bash
|
|
# Run in headless mode (non-interactive)
|
|
claude -p "Run all tests and generate report"
|
|
|
|
# With permission mode for CI
|
|
claude -p "Run tests" --permission-mode dontAsk
|
|
|
|
# With Auto Mode for fully autonomous CI tasks
|
|
claude --enable-auto-mode -p "Run tests and fix failures"
|
|
|
|
# With hooks for automation
|
|
# See 09-advanced-features/README.md
|
|
```
|
|
|
|
### Learning & Experimentation
|
|
```bash
|
|
# Use plan mode for safe analysis
|
|
claude --permission-mode plan
|
|
|
|
# Experiment safely - checkpoints are created automatically
|
|
# If you need to rewind: press Esc+Esc or use /rewind
|
|
```
|
|
|
|
### Agent Teams
|
|
```bash
|
|
# Enable agent teams
|
|
export CLAUDE_AGENT_TEAMS=1
|
|
|
|
# Or in settings.json
|
|
{ "agentTeams": { "enabled": true } }
|
|
|
|
# Start with: "Implement feature X using a team approach"
|
|
```
|
|
|
|
### Scheduled Tasks
|
|
```bash
|
|
# Run a command every 5 minutes
|
|
/loop 5m /check-status
|
|
|
