- Added USB device detection and monitoring capabilities.
- Updated SSH usage patterns to reflect dynamic host configurations.
- Introduced automatic system discovery from journal logs, including OS detection and system profiling.
- Enhanced configuration file intelligence with semantic search and categorization.
- Expanded knowledge base structure and automatic learning processes.
- Clarified the architecture and key modules for better understanding of system components.
CRITICAL: Prevents inconsistent sudo/SSH patterns across codebase.
Created command_patterns.py with:
- Single source of truth for ALL command execution patterns
- SSH key path constant: /var/lib/macha/.ssh/id_ed25519
- Remote user constant: macha
- sudo prefix for all remote commands
- Helper functions: build_ssh_command(), transform_ssh_command()
- Self-validation tests
Updated files to use centralized patterns:
- tools.py: Uses transform_ssh_command()
- remote_monitor.py: Uses build_ssh_command()
- system_discovery.py: Uses build_ssh_command()
- DESIGN.md: Documents centralized approach
Benefits:
- Impossible to have inconsistent patterns
- Single place to update if needed
- Self-documenting with validation tests
- Prevents future refactoring errors
DO NOT duplicate these patterns in other files - always import.
CRITICAL FIX: SSH keys were not being auto-loaded, causing connection failures.
Changes:
- tools.py: SSH commands now include -i /var/lib/macha/.ssh/id_ed25519
- remote_monitor.py: Use explicit key path instead of sudo ssh
- system_discovery.py: Added explicit key path to all SSH calls
- system_prompt.txt: Document automatic SSH key loading
- DESIGN.md: Clarify CRITICAL requirement for explicit key paths
All SSH operations now explicitly specify:
-i /var/lib/macha/.ssh/id_ed25519 -o StrictHostKeyChecking=no
This ensures Macha can reliably connect to remote hosts without
depending on SSH agent or automatic key discovery.
Macha is now a standalone NixOS flake that can be imported into other
systems. This provides:
- Independent versioning
- Easier reusability
- Cleaner separation of concerns
- Better development workflow
Includes:
- Complete autonomous system code
- NixOS module with full configuration options
- Queue-based architecture with priority system
- Chunked map-reduce for large outputs
- ChromaDB knowledge base
- Tool calling system
- Multi-host SSH management
- Gotify notification integration
All capabilities from DESIGN.md are preserved.
