Major project milestone: Successfully migrated home lab management tool from Bash to GNU Guile Scheme
## Completed Components ✅
- **Project Foundation**: Complete directory structure (lab/, mcp/, utils/)
- **Working CLI Tool**: Functional home-lab-tool.scm with command parsing
- **Development Environment**: NixOS flake.nix with Guile, JSON, SSH, WebSocket libraries
- **Core Utilities**: Logging, configuration, SSH utilities with error handling
- **Module Architecture**: Comprehensive lab modules and MCP server foundation
- **TaskMaster Integration**: 25-task roadmap with project management
- **Testing & Validation**: Successfully tested in nix develop environment
## Implementation Highlights
- Functional programming patterns with immutable data structures
- Proper error handling and recovery mechanisms
- Clean module separation with well-defined interfaces
- Working CLI commands: help, status, deploy (with parsing)
- Modular Guile architecture ready for expansion
## Project Structure
- home-lab-tool.scm: Main CLI entry point (working)
- utils/: logging.scm, config.scm, ssh.scm (ssh needs syntax fixes)
- lab/: core.scm, machines.scm, deployment.scm, monitoring.scm
- mcp/: server.scm foundation for VS Code integration
- flake.nix: Working development environment
## Next Steps
1. Fix SSH utilities syntax errors for real connectivity
2. Implement actual infrastructure status checking
3. Complete MCP server JSON-RPC protocol
4. Develop VS Code extension with MCP client
This represents a complete rewrite maintaining compatibility while adding:
- Better error handling and maintainability
- MCP server for AI/VS Code integration
- Modular architecture for extensibility
- Comprehensive project management with TaskMaster
The Bash-to-Guile migration provides a solid foundation for advanced
home lab management with modern tooling and AI integration.
- Updated lab status command to use admin SSH aliases (admin-sleeper, admin-grey, admin-reverse)
- Fixed SSH authentication issues by using correct admin keys
- Improved verbose mode to show detailed connection attempts
- Updated legacy deployment to use admin aliases for consistency
- Now properly connects to sleeper-service and grey-area via admin access
- reverse-proxy showing as unreachable due to fail2ban (expected security behavior)
Resolves SSH connectivity issues that were blocking task completion assessment.
✅ Completed Tasks:
- Task 6: Successfully tested deploy-rs on all machines (grey-area, reverse-proxy, congenital-optimist)
- Task 7: Added deploy-rs status monitoring to lab tool
🔧 Infrastructure Improvements:
- Added sma user to local machine for consistent SSH access
- Created shared shell-aliases.nix module to eliminate conflicts
- Enhanced lab status command with deploy-rs deployment info
- Added generation tracking, build dates, and uptime monitoring
🚀 Deploy-rs Status:
- All 4 machines successfully tested with both dry-run and actual deployments
- Automatic rollback protection working correctly
- Health checks and magic rollback functioning properly
- Tailscale connectivity verified across all nodes
📊 New Status Features:
- lab status --deploy-rs: Shows deployment details
- lab status -v: Verbose SSH connection info
- lab status -vd: Combined verbose + deploy-rs info
- Real-time generation and system closure information
The hybrid deployment approach is now fully operational with modern safety features while maintaining legacy compatibility.
- Add Nix package for task-master-ai in packages/claude-task-master-ai.nix
- Update packages/default.nix to export the new package
- Add comprehensive documentation for packaging and MCP integration
- Add guile scripting solution documentation
