# Implementation Plan: Cache Analytics Display (cache_analytics_20260306)
## Phase 1: Cache Stats Integration
- [ ] Task: Initialize MMA Environment
- [ ] Task: Verify get_gemini_cache_stats
- WHERE: src/ai_client.py
- WHAT: Check existing function
- HOW: Review implementation
> **Reference:** [Spec](./spec.md) | [Architecture Guide](../../../docs/guide_architecture.md)
## Phase 1: Foundation & Research
Focus: Verify existing infrastructure and set up panel structure
- [ ] Task 1.1: Initialize MMA Environment
- Run `activate_skill mma-orchestrator` before starting
- [ ] Task 1.2: Verify ai_client.get_gemini_cache_stats()
- WHERE: `src/ai_client.py` lines ~200-230
- WHAT: Confirm function exists and returns expected dict structure
- HOW: Use `manual-slop_py_get_definition` on `get_gemini_cache_stats`
- OUTPUT: Document exact return dict structure in task notes
- [ ] Task 1.3: Verify ai_client.cleanup()
- WHERE: `src/ai_client.py` line ~220
- WHAT: Confirm function clears `_gemini_cache`
- HOW: Use `manual-slop_py_get_definition` on `cleanup`
- SAFETY: Note that cleanup() also clears other resources - document side effects
## Phase 2: Panel Implementation
- [ ] Task: Create cache panel
- WHERE: src/gui_2.py
- WHAT: Display cache stats
- HOW: imgui widgets
- SAFETY: Handle no cache
Focus: Create the GUI panel structure
## Phase 3: TTL & Controls
- [ ] Task: Display TTL countdown
- WHERE: src/gui_2.py
- WHAT: Time until cache rebuild
- HOW: Calculate from cache_created_at
- [ ] Task: Add clear button
- WHERE: src/gui_2.py
- WHAT: Manual cache clear
- HOW: Call ai_client.cleanup()
- [ ] Task 2.1: Add cache panel state variables
- WHERE: `src/gui_2.py` in `App.__init__` (around line 170)
- WHAT: Add minimal state if needed (likely none - read directly from ai_client)
- HOW: Follow existing state initialization pattern
- CODE STYLE: 1-space indentation
- SAFETY: No locks needed - read-only access to ai_client globals
## Phase 4: Verification
- [ ] Task: Test cache display
- [ ] Task: Conductor - Phase Verification
- [ ] Task 2.2: Create _render_cache_panel() method
- WHERE: `src/gui_2.py` after other `_render_*_panel()` methods
- WHAT: New method that displays cache statistics
- HOW:
```python
def _render_cache_panel(self) -> None:
if self.current_provider != "gemini":
return
if not imgui.collapsing_header("Cache Analytics"):
return
stats = ai_client.get_gemini_cache_stats()
# Render stats...
```
- CODE STYLE: 1-space indentation, NO COMMENTS
- [ ] Task 2.3: Integrate panel into main GUI
- WHERE: `src/gui_2.py` in `_gui_func()` method
- WHAT: Call `_render_cache_panel()` in appropriate location
- HOW: Add near token budget panel or in settings area
- SAFETY: Ensure not called during modal dialogs
## Phase 3: Statistics Display
Focus: Implement the visual statistics rendering
- [ ] Task 3.1: Implement cache status display
- WHERE: `src/gui_2.py` in `_render_cache_panel()`
- WHAT: Show cache existence and age
- HOW:
- `imgui.text(f"Cache Active: {stats['cache_exists']}")`
- `imgui.text(f"Age: {format_age(stats['cache_age_seconds'])}")`
- HELPER: Create `format_age(seconds: float) -> str` helper
- CODE STYLE: 1-space indentation
- [ ] Task 3.2: Implement TTL countdown display
- WHERE: `src/gui_2.py` in `_render_cache_panel()`
- WHAT: Show remaining TTL with percentage
- HOW:
- `remaining = stats['ttl_remaining']`
- `percentage = (remaining / stats['ttl_seconds']) * 100`
- Use `imgui.progress_bar()` for visual
- VISUAL: Warning color when percentage < 20% (use `vec4` colors defined at top of file)
- [ ] Task 3.3: Implement requests counter (optional enhancement)
- WHERE: `src/gui_2.py` in `_render_cache_panel()`
- WHAT: Show estimated "requests while cache active"
- HOW: Add `self._cache_request_count: int = 0` state, increment on send
- SAFETY: This requires hooking into send flow - may skip if complex
## Phase 4: Manual Controls
Focus: Implement the cache clear functionality
- [ ] Task 4.1: Add clear cache button
- WHERE: `src/gui_2.py` in `_render_cache_panel()`
- WHAT: Button that clears the Gemini cache
- HOW:
```python
if imgui.button("Clear Cache"):
ai_client.cleanup()
# Optionally set a flag to show "Cache cleared" message
```
- SAFETY: `cleanup()` clears ALL caches, not just Gemini - document this
- [ ] Task 4.2: Add clear confirmation/feedback
- WHERE: `src/gui_2.py` in `_render_cache_panel()`
- WHAT: Show feedback after clear
- HOW: Add `self._cache_just_cleared: bool = False` flag, show message, auto-clear after 3s
- CODE STYLE: 1-space indentation
## Phase 5: Testing
Focus: Verify all functionality works correctly
- [ ] Task 5.1: Write unit tests for cache panel
- WHERE: `tests/test_cache_panel.py` (new file)
- WHAT: Test panel visibility, stats display, clear button
- HOW: Use `mock_app` or `app_instance` fixture from `conftest.py`
- PATTERN: Follow `test_gui_phase4.py` as reference
- CODE STYLE: 1-space indentation
- [ ] Task 5.2: Write integration test with live_gui
- WHERE: `tests/test_cache_panel.py`
- WHAT: Test with actual Gemini provider (or mock)
- HOW: Use `live_gui` fixture, set provider to 'gemini', verify panel shows
- ARTIFACTS: Write to `tests/artifacts/`
- [ ] Task 5.3: Conductor - Phase Verification
- Run targeted tests: `uv run pytest tests/test_cache_panel.py -v`
- Verify no lint errors in modified files
- Manual visual verification in GUI
## Implementation Notes
### Thread Safety Analysis
- `ai_client.get_gemini_cache_stats()` reads `_gemini_cache` and `_gemini_cache_created_at`
- These are set on the asyncio worker thread during `_send_gemini()`
- Reading from GUI thread is safe (atomic types) but values may be slightly stale
- No locks required for display purposes
### Code Style Checklist
- [ ] 1-space indentation throughout
- [ ] CRLF line endings on Windows
- [ ] No comments unless explicitly documenting complex logic
- [ ] Type hints on all new functions
- [ ] Follow existing `vec4` color naming pattern
### Files Modified
- `src/gui_2.py`: Add `_render_cache_panel()`, integrate into `_gui_func()`
- `tests/test_cache_panel.py`: New test file
