   - Security features
   - Troubleshooting guide

### Package Integration
✅ **package.json** - Updated postinstall hook
   - Now runs: `postinstall-wizard.cjs && create-cursor-hooks.cjs`

## Security Features Implemented

### Isolation Enforcement
- ✅ Blocks framework files (`.versatil/`, `versatil/`, `supabase/`) in user projects
- ✅ Validates all file edits and shell commands
- ✅ Prevents accidental commits of framework data

### Destructive Command Protection
Blocks these patterns:
- `rm -rf`, `git reset --hard`, `git push --force`
- `DROP DATABASE`, `DROP TABLE`, `TRUNCATE TABLE`, `DELETE FROM`
- `mkfs`, `dd if=`, `> /dev/`, `chmod 000`, `chown root`

### Production Deployment Protection
Blocks these patterns:
- `npm publish`
- `git push origin main/master`
- `vercel --prod`, `netlify deploy --prod`
- `docker push.*:latest`
- `kubectl apply.*production`
- `terraform apply.*prod`

### Sensitive File Warnings
Warns on these patterns:
- `.env`, `credentials.json`, `secrets.yaml`
- `id_rsa`, `.pem`, `.key`, `private.key`, `auth.json`
- `.aws/credentials`, `.gcp/credentials`

## Automation Features Implemented

### Code Formatting
- ✅ Auto-formats TypeScript/JavaScript with Prettier
- ✅ Auto-formats Python with Black
- ✅ Runs on every file save (via afterFileEdit hook)

### RAG Memory Updates
- ✅ Updates on file changes (async, non-blocking)
- ✅ Tracks file access patterns
- ✅ Codifies learnings from sessions

### Agent Activation Suggestions
- ✅ Detects keywords in prompts
- ✅ Suggests relevant OPERA agents (Maria-QA, James, Marcus, Dana, Sarah, Alex, Dr.AI-ML)
- ✅ Enriches prompts with project context

### Stress Test Triggering (Rule 2)
- ✅ Auto-triggers for API file changes
- ✅ Detects patterns: `*.api.*`, `*/routes/*`, `*/controllers/*`, `*/api/*`
- ✅ Runs asynchronously (doesn't block saves)

## Logging & Monitoring

### Log Files Created
- `~/.versatil/logs/hooks.log` - All hook executions
- `~/.versatil/logs/file-access.log` - File access tracking
- `~/.versatil/logs/session-metrics.log` - Session metrics

### Metrics Files
- `~/.versatil/metrics/agent-{agent}.json` - Per-agent performance
- `~/.versatil/learning/session-{id}.json` - Session summaries

## Verification Tests

### Manual Tests Performed
✅ afterFileEdit with normal file - PASSED
✅ afterFileEdit with isolation violation - BLOCKED (correct)
✅ beforeShellExecution with safe command - ALLOWED
✅ beforeShellExecution with destructive command - BLOCKED (correct)
✅ beforeReadFile with normal file - ALLOWED (not sensitive)
✅ beforeReadFile with sensitive file - WARNING shown (correct)
✅ beforeSubmitPrompt with "test" keyword - Maria-QA suggested
✅ stop hook - Session logged successfully

## Integration with CLAUDE.md

The hooks infrastructure is documented in CLAUDE.md:
- Section: "Cursor Hooks Integration (v1.7+)" (lines 908-1062)
- Coverage: All 5 hooks with examples
- Lifecycle examples provided
- Benefits table included
- Custom configuration documented

## Acceptance Criteria

✅ All shell scripts executable (`chmod +x`)
✅ Hooks config created on `npm install`
✅ Isolation validation blocks violations
✅ Security checks prevent destructive operations
✅ Stop hook stores session learnings to RAG
✅ Complete documentation provided
✅ Manual tests verify all functionality

## Next Steps

1. **Restart Cursor** to activate hooks
2. **Monitor logs**: `tail -f ~/.versatil/logs/hooks.log`
3. **Check metrics** after sessions: `cat ~/.versatil/metrics/agent-*.json`
4. **Review learnings**: `ls -la ~/.versatil/learning/`
