Add new CLI option to update installation manifests without full reinstallation:
• Add --update-manifest-only flag to installer CLI
• Implement comprehensive manifest update logic in installer.js
• Scan existing installations and regenerate accurate manifests
• Preserve configuration while updating file hashes and metadata
• Add npm run update:manifest convenience script
Features:
- Validates existing .bmad-core installations
- Scans all files recursively and generates current state manifests
- Supports both core and expansion pack installations
- Compatible with all usage patterns (CLI, npm, npx)
- Fast execution with zero file disruption
Resolves manifest sync issues when installations drift from recorded state.
Eliminates need for full reinstallation when only manifest needs updating.
