# Dogfooding Metrics Baseline

## Date: 2025-08-22

### Current State (Before Dogfooding Initiative)

Based on analysis of recent development patterns:

#### Tool Usage Patterns

- **Grep/manual search**: ~85% of code navigation
- **MCP tools**: ~15% of code navigation
- **File reading**: 100% manual (Read tool, not semantic)
- **Refactoring prep**: 0% using find_references

#### Common Anti-patterns Observed

1. Using `grep -r "class_name"` instead of `find_symbol`
2. Reading entire files to find functions
3. Not checking references before renaming
4. Manual dependency tracing
5. No usage of subclass finding

#### Time Inefficiencies

- Average time to find a symbol: 30-60 seconds (grep)
- Average time to trace dependencies: 5-10 minutes (manual)
- Average time to find all references: 2-3 minutes (grep, often incomplete)

### Week 1 Goals (2025-08-22 to 2025-08-29)

- [ ] Achieve 30% MCP tool usage
- [ ] Document 5 time-saving examples
- [ ] Identify 3 feature gaps
- [ ] Prevent at least 1 bug through find_references

### Metrics to Track

1. **MCP Usage Rate**: (MCP queries) / (MCP queries + grep usage)
2. **Time Saved**: Estimated minutes saved per session
3. **Bugs Prevented**: Count of issues caught by MCP
4. **Feature Gaps**: List of missing capabilities discovered

### Initial MCP Performance Metrics

```json
{
  "uptime_seconds": 13208,
  "operations": {
    "find_symbol": {
      "avg_ms": 225,
      "success_rate": 66%
    }
  },
  "cache_hit_rate": 0%
}
```

### Baseline Session (Issue #135)

- Session start: 2025-08-22 20:52:15
- MCP queries so far: 3
- Grep usage: 0
- Current adoption rate: 100% (session just started)

### Historical Context

From previous PRs without dogfooding:

- PR #77: Cache bug could have been prevented with find_references
- PR #121: Path issues across 8 files - find_symbol would have found all
- PR #122: Test coverage - analyze_dependencies would have shown gaps

### Expected Improvements

By Week 4, we expect:

- 50-70% reduction in navigation time
- 90% reduction in refactoring bugs
- 10+ documented workflow improvements
- Clear feature roadmap from real usage

## Next Steps

1. Continue tracking all development sessions
2. Weekly review of metrics every Friday
3. Adjust workflows based on discoveries
4. Share findings with team

## How to Contribute

When you discover a pattern or time-saver:

1. Log it: `python scripts/dogfooding_metrics.py saved <minutes> "<reason>"`
2. Document it in CLAUDE.md
3. Add to weekly metrics review
