## Integration Points

### Existing Commands
The zero-config installer integrates with existing setup commands:

1. **`/setup`** - Machine-level setup
   - Can now call installer scripts
   - Validates dependencies before setup
   - Builds MCP servers automatically

2. **`/setup-project`** - Project-level setup
   - Can use installer validation
   - Checks MCP server builds
   - Verifies framework structure

3. **`/update-project`** - Update existing project
   - Can rebuild MCP servers
   - Validates updated installation

### MCP Servers
The build system handles all 3 MCP servers:

1. **copilot-memory** (Node.js 18+, TypeScript)
2. **task-copilot** (Node.js 18+, TypeScript)
3. **skills-copilot** (Node.js 18+, TypeScript)

### Future Integration
Ready for integration with:
- GitHub Actions (CI/CD)
- Docker containers
- Cloud deployment scripts
- Team onboarding automation

---

## Known Limitations

### High Priority
1. **NPM Package Installation Logic Incomplete**
   - `installGlobal()` is stub - needs file copying
   - `installProject()` is stub - needs file copying
   - Need .mcp.json generation
   - Need symlink creation

2. **Update Command Not Implemented**
   - CLI exists but no functionality
   - Need git pull + rebuild logic

3. **Windows Not Supported**
   - No PowerShell scripts
   - Shell scripts won't run natively
   - Need WSL or native Windows support

### Medium Priority
4. **No Non-Interactive Mode**
   - Auto-fix requires confirmation
   - Need --yes or --force flag
   - Blocks CI/CD usage

5. **JSON Output Incomplete**
   - Validation script has no JSON mode
   - Only dependency check has JSON

6. **No Progress Persistence**
   - Can't resume failed installation
   - No checkpoint/rollback mechanism

### Low Priority
7. **No Telemetry**
   - Can't track installation success rate
   - No error reporting to maintainers

8. **No Version Management**
   - Can't install specific version
   - No version compatibility checks

---

## Next Steps

### Immediate (Before Testing)
1. Make all scripts executable:
   ```bash
   ./scripts/install/make-executable.sh
   ```

2. Test dependency detection:
   ```bash
   ./scripts/install/check-dependencies.sh
   ```

3. Build MCP servers:
   ```bash
   ./scripts/install/build-servers.sh build
   ```

### Short Term (Next Sprint)
1. Complete NPM package installation logic
2. Add non-interactive mode (--yes flag)
3. Implement update command
4. Add comprehensive tests

### Medium Term
1. Windows support (PowerShell scripts)
2. CI/CD integration (GitHub Actions)
3. Docker support
4. Version management

### Long Term
1. GUI installer
2. Telemetry and analytics
3. Auto-update mechanism
4. Cloud deployment templates

## Files to Make Executable

Run this command to make all scripts executable:

```bash
chmod +x scripts/install/check-dependencies.sh
chmod +x scripts/install/build-servers.sh
chmod +x scripts/install/validate-installation.sh
chmod +x scripts/install/make-executable.sh
chmod +x scripts/install/platforms/macos.sh
chmod +x scripts/install/platforms/linux.sh
chmod +x packages/installer/bin/claude-copilot.js
