## CHANGES
- refactor BuildSession raw mode to prepend system to user content
- ensure raw mode messages always have User role
- keep existing user message when no systemMessage provided
- append systemMessage separately in non-raw mode sessions
- store original cmd.Env before context-based exec command creation
- recreate exec command with context then restore originalEnv
- add comments clarifying raw vs non-raw handling behavior
- Successfully implemented path-based registry storage
- Moved to storing paths instead of full configurations
- Implemented proper hash verification for both configs and executables
- Registry format now clean and minimal.
File-Based Output Implementation
- Successfully implemented file-based output handling
- Demonstrated clean interface requiring only path output
- Properly handles cleanup of temporary files
- Verified working with both local and remote operations
Process template variables ({{var}}) consistently in both pattern files
and raw input messages. Previously variables were only processed when
using pattern files.
- Add template variable processing for raw input in BuildSession
- Initialize messageContent explicitly
- Remove errantly committed build artifact (fabric binary in previous commit)
Add initial set of utility plugins for the template system:
- datetime: Date/time formatting and manipulation
- fetch: HTTP content retrieval and processing
- file: File system operations and content handling
- sys: System information and environment access
- text: String manipulation and formatting operations
Each plugin includes:
- Implementation with comprehensive test coverage
- Markdown documentation of capabilities
- Integration with template package
This builds on the template system to provide practical utility functions
while maintaining a focused scope for the initial plugin release.
