# Known Limitations

Current limitations, known issues, and planned improvements for macOS Resource Optimizer.

**Last Updated**: 2025-11-30 (Phase 3 Day 6)

## Phase 3 Day 6 - Current Status

### Implementation Gaps

**UV Scripts** (12/12 Implemented):
- ✅ All 12 scripts completed
- ✅ ASTRAL UV format with embedded dependencies
- ✅ Parallel execution via analyze_all.py
- ✅ Cache implementation (cache.py)
- ✅ Monitoring system (monitor.py)
- ✅ Report generation (report.py)

**MoAI Integration** (2/8 Agents):
- ✅ 2 manager agents updated (Bash(uv run) pattern)
- ❌ 6 expert agents not yet updated
- ❌ 0/5 commands updated with UV workflows
- ❌ SKILL.md references conceptual architecture (not UV scripts)

**Testing** (191/278 Passing):
- ✅ 68.7% test pass rate
- ❌ 87 tests failing (31.3%)
- ❌ Error handling edge cases incomplete
- ❌ Integration tests incomplete

---

## Known Issues

### 1. Cache Thread Safety (Low Priority)

**Issue**: cache.py does not implement thread-safe operations.

**Impact**:
- Low - Current usage is single-process
- No concurrent access expected

**Workaround**:
- Use file-based locking if needed
- Current implementation sufficient for single-process use

**Fix Timeline**: Phase 6+ (if needed)

### 2. Test Coverage (Medium Priority)

**Issue**: 87/278 tests failing (68.7% pass rate).

**Categories**:
- Error handling edge cases: 35 failures
- Integration tests: 28 failures
- Performance benchmarks: 15 failures
- Mock configuration: 9 failures

**Impact**:
- Medium - Core functionality works
- Edge cases not validated

**Fix Timeline**: Phase 5 Day 8 (dedicated test fixing)

### 3. Agent Integration (High Priority)

**Issue**: Only 2/8 manager agents use Bash(uv run) pattern.

**Missing Updates**:
- ❌ expert-cpu-optimizer
- ❌ expert-memory-optimizer
- ❌ expert-disk-optimizer
- ❌ expert-network-optimizer
- ❌ expert-battery-optimizer
- ❌ expert-thermal-optimizer

**Impact**:
- High - Agent delegation incomplete
- Direct UV script usage works as workaround

**Fix Timeline**: Phase 4 Day 7

### 4. Command Workflows (High Priority)

**Issue**: 0/5 commands updated with UV script workflows.

**Missing Commands**:
- ❌ /macos-resource-optimizer:0-init
- ❌ /macos-resource-optimizer:1-analyze
- ❌ /macos-resource-optimizer:2-optimize
- ❌ /macos-resource-optimizer:3-monitor
- ❌ /macos-resource-optimizer:4-report

**Impact**:
- High - User-facing commands not functional
- Direct UV script usage works as workaround

**Fix Timeline**: Phase 4 Day 7

### 5. Documentation Mismatch (Medium Priority)

**Issue**: SKILL.md describes conceptual wrapper architecture, not actual UV script implementation.

**Gaps**:
- PythonEngineWrapper class (conceptual, not implemented)
- coordinator.py references (not used in UV scripts)
- Wrapper patterns (actual pattern is Bash(uv run))

**Impact**:
- Medium - Confusing for new developers
- Documentation updates in progress (this task)

**Fix Timeline**: Phase 3 Day 6 (in progress)

### 6. Performance Validation (Medium Priority)

**Issue**: Performance benchmarks not yet run for all 12 scripts.

**Missing Benchmarks**:
- Individual script execution time
- analyze_all.py parallel efficiency
- Cache hit rate validation
- UV startup overhead measurement

**Impact**:
- Medium - Performance targets not validated
- Scripts likely meet targets (simple operations)

**Fix Timeline**: Phase 3 Day 6 (parallel with this task)

---

## Limitations by Category

### Architecture

**Conceptual vs Actual**:
- ❌ Documentation describes wrapper classes (not implemented)
- ✅ Actual implementation uses direct UV script execution
- ❌ Integration patterns not fully updated

**Recommendation**: Update SKILL.md to reflect UV script architecture.

### Performance

**Unvalidated Targets**:
- ❌ analyze_all.py <2.5s (not benchmarked)
- ❌ Individual scripts <0.5s (not benchmarked)
- ❌ Cache hit rate validation (not measured)

**Recommendation**: Run comprehensive benchmarks (Phase 3 Day 6).

### Testing

**Edge Cases**:
- ❌ Concurrent execution (not tested)
- ❌ File permission errors (partially tested)
- ❌ Network failures (not tested)
- ❌ Invalid JSON parsing (partially tested)

**Recommendation**: Dedicated test fixing phase (Phase 5 Day 8).

### Integration

**MoAI Ecosystem**:
- ❌ Only 2/8 agents updated
- ❌ 0/5 commands functional
- ✅ Direct Bash(uv run) works

**Recommendation**: Complete agent/command updates (Phase 4 Day 7).

## Planned Fixes

### Phase 4 Day 7: MoAI Integration Complete

**Deliverables**:
- [ ] Update 6 remaining expert agents
- [ ] Update 5 commands with UV workflows
- [ ] Update SKILL.md with UV script patterns
- [ ] Validate agent delegation

**Expected Outcome**: All agents and commands functional.

### Phase 5 Day 8: Test Suite Complete

**Deliverables**:
- [ ] Fix 87 failing tests
- [ ] Achieve 85%+ test pass rate
- [ ] Add missing edge case tests
- [ ] Performance regression tests

**Expected Outcome**: Production-ready test coverage.

### Phase 6 Day 9: Documentation Finalized

**Deliverables**:
- [ ] Migration guide (v6 → v7)
- [ ] Performance report (all benchmarks)
- [ ] Final validation checklist
- [ ] Deployment guide

**Expected Outcome**: Complete documentation package.

## Workarounds

### Until Phase 4 Completion

**Direct UV Script Usage**:
```bash
# Instead of agent delegation
# ❌ Task(subagent_type="expert-cpu-optimizer", ...)

# Use direct execution
# ✅ uv run .data/scripts/analyze_cpu.py --json
```

### Until Phase 5 Completion

**Manual Testing**:
```bash
# Run individual scripts manually
uv run status.py
uv run analyze_all.py --json
uv run optimize.py --json
```

### Until Phase 6 Completion

**Consult Phase Summaries**:
- `.data/PHASE-3-SUMMARY.md` - Advanced features status
- `.data/tests/TEST_SUMMARY.md` - Test suite status
- `.data/VERIFICATION-SUMMARY.md` - Script verification

---

## Non-Issues (Intentional Design)

### 1. No coordinator.py

**Status**: Intentional - UV scripts replace coordinator.py

**Reason**: Simpler architecture, better performance

### 2. No PythonEngineWrapper class

**Status**: Intentional - Direct Bash(uv run) execution

**Reason**: Token efficiency, zero overhead

### 3. Conceptual documentation preserved

**Status**: Intentional - Architecture reference maintained

**Reason**: Design patterns still valuable for understanding
