First indexed and scored.

## MCP tools (4)

### `coverage_summary` (~41 tokens)

Analyzes an LCOV coverage file and returns overall project line coverage percentage. Use this before making code changes to establish a baseline or after changes to verify impact.

### `coverage_file_summary` (~36 tokens)

Analyzes an LCOV coverage file and returns line coverage percentage for a specific file. Use this to check coverage for individual files.

### `start_recording` (~29 tokens)

Records the current coverage as a baseline snapshot. Use this before making code changes to later compare against.

### `get_diff_since_start` (~37 tokens)

Compares current coverage against the recorded baseline and returns the impact (positive or negative). Use this after making changes to see coverage impact.
