 ## Phase 2: Expose Necessary Prompts in GUI
-- [ ] Task: Modify `src/gui_2.py` to add new editable text areas in the "AI Settings" or "Project Settings" panel.
-    - [ ] Create fields for global system tool instructions.
-    - [ ] Create fields for project-specific context markers.
-- [ ] Task: Update `src/app_controller.py` state initialization to load these new fields from `config.toml` and `manual_slop.toml`.
-- [ ] Task: Ensure changes are correctly saved and flushed to the project files via `_flush_to_project()` and `_flush_to_config()`.

 ## Phase 3: Cull and Integrate Configured Prompts
 - [ ] Task: Update `src/ai_client.py`'s `_get_combined_system_prompt()` to utilize the user-configured tool instructions from the AppController state instead of hardcoded strings.
