Branch Coverage Gap Analysis & Fix

Find branch coverage gaps in changed code and write missing tests to fill them.

Phase 1: Identify Changes

Ask if there is a related spec file for scenario coverage analysis.

Run git diff (or git diff HEAD if there are staged changes) to identify changed source and test files.

If no git changes exist, fall back to files the user mentioned or edited earlier in the conversation.

Phase 2: Launch Gap Analysis Agents in Parallel

Use the Agent tool to launch agents concurrently. Pass each agent the full diff for complete context.

Agent 1: Source ↔ Test Branch Coverage (always launched)

For each changed source file:
