## Workflow Recommendations

### 🧪 Critical: Increase Test Coverage

**Current**: 54%
**Target**: 80%+
**Gap**: 26 percentage points

**Action Plan**:

1. Add tests for new agents (WarningSuppressionAgent, DeadCodeRemovalAgent)
1. Cover edge cases in BatchProcessor
1. Add integration tests for async I/O
1. Target 80% coverage before next release

**Commands**:

```bash
# Check current coverage
python -m pytest --cov=crackerjack --cov-report=html

# Run tests with coverage tracking
python -m crackerjack run --run-tests --cov
```

### 🌿 Adopt Feature Branch Workflow

**Current**: Direct commits to `main`
**Recommended**: Feature branches with PRs

**Benefits**:

- Better code review
- Safer integration
- Cleaner git history
- Easier rollback

**Workflow**:

```bash
# Create feature branch
git checkout -b feature/warning-suppression-agent

# Make changes and commit
git add .
git commit -m "Implement WarningSuppressionAgent"

# Push and create PR
git push -u origin feature/warning-suppression-agent
gh pr create --title "Add WarningSuppressionAgent"
```

### 📊 Implement Issue Tracking

**Current**: Ad-hoc task management
**Recommended**: GitHub Issues + Projects

**Setup**:

```bash
# Create GitHub Issue for each major feature
gh issue create --title "Implement WarningSuppressionAgent" \
  --body "Auto-detect and fix pytest warnings" \
  --label "enhancement,agent"

# Link commits to issues
git commit -m "Implement WarningSuppressionAgent (#123)"
```

### 🔧 Performance Optimization

**Current**: 12.4s per issue
**With Async I/O**: ~4s per issue (3x speedup)

**Next Steps**:

1. Profile with real workloads
1. Measure actual speedup
1. Optimize based on metrics

### 📚 Documentation Maintenance

**Current**: 15 documentation files (4,000+ lines)
**Status**: ✅ Excellent

**Maintain**:

- Keep completion summaries up to date
- Update user guides with new features
- Archive old plans appropriately

## Session Insights

### What Worked Well

1. **Parallel Track Development**

   - Track 1 (Test Failures): 8 weeks ✅
   - Track 2 (Dead Code): 4 weeks ✅
   - Both completed on schedule

1. **Async I/O Integration**

   - Thread pool executor pattern
   - Non-blocking file operations
   - 3x speedup potential

1. **Agent System**

   - 9 agents now available
   - Clean routing via ISSUE_TYPE_TO_AGENTS
   - Consistent API across all agents

1. **Documentation**

   - Comprehensive coverage
   - User guides + troubleshooting
   - Performance optimization plans

### What Could Be Improved

1. **Test Coverage**

   - Need more unit tests for agents
   - Integration test coverage gaps
   - Edge case testing

1. **Git Workflow**

   - Direct main commits (risky)
   - No PR review process
   - Missing issue tracking

1. **Complexity Management**

   - Some methods >15 complexity
   - Need refactoring for maintainability

1. **Performance Validation**

   - Profiling done but not validated
   - Real-world metrics needed
   - Benchmark against baseline

______________________________________________________________________

## Context Window Analysis

### Current Usage: **MODERATE** (estimated ~40-50%)

**Recommendation**: ✅ **No /compact needed yet**

**Indicators**:

- Session is responsive
- No significant lag
- Tool performance good

**When to /compact**:

- At ~70% context usage
- If tool calls slow down
- Before starting new major feature

**Current Action**: Continue working, monitor usage

______________________________________________________________________

## Storage Optimization Status

### Actions Taken Automatically

✅ **Checkpoint commit created** (69a38d46)
✅ **Reflection stored** (quality: 76/100)
⚠️ **Auto-compaction skipped** (module import error)

### Manual Cleanup Recommended

#### 1. Git Repository Cleanup

```bash
# Remove merged branches
git branch --merged | grep -v main | xargs git branch -d

# Prune remote branches
git remote prune origin

# Run garbage collection
git gc --auto --prune=now
```

#### 2. Python Cache Cleanup

```bash
# Remove __pycache__ directories
find . -type d -name __pycache__ -exec rm -rf {} +

# Remove .pyc files
find . -name "*.pyc" -delete

# Remove .coverage files
find . -name ".coverage" -delete
```

#### 3. Dependency Cache

```bash
# Clean UV package cache
uv cache clean

# Remove .pytest_cache
pytest --cache-clear
```

#### 4. Documentation Cleanup

```bash
# Archive old completion summaries
mkdir -p docs/archive
mv docs/*_COMPLETE.md docs/archive/ 2>/dev/null || true

# Remove duplicate/obsolete files
# Manual review required
```
