"""Self-modification loop — read source, generate edits, test, commit.
|
||||
|
||||
Orchestrates the full cycle for Timmy to modify its own codebase:
|
||||
1. Create a working git branch
|
||||
2. Read target source files
|
||||
3. Send instruction + source to the LLM
|
||||
4. Validate syntax before writing
|
||||
5. Write edits to disk
|
||||
6. Run pytest
|
||||
7. On success -> git add + commit; on failure -> revert
|
||||
8. On total failure -> diagnose from report, restart autonomously
|
||||
|
||||
Supports multiple LLM backends:
|
||||
- "ollama" — local Ollama (default, sovereign)
|
||||
- "anthropic" — Claude API via Anthropic SDK
|
||||
- "auto" — try anthropic first (if key set), fall back to ollama
|
||||
|
||||
Reports are saved to data/self_modify_reports/ for debugging.
