Validate Test Coverage

Overview

Cross-reference acceptance criteria from user stories against existing test cases to identify coverage gaps. This is not about code coverage percentages — it is about whether every requirement has a corresponding test at the appropriate level of the test pyramid, including edge cases and error states.

Workflow

1. Read project context — Read .chalk/docs/ for:

   • User stories with acceptance criteria (*user_stories*, *prd*, *requirements*)
   • Test plans (*test_plan*)
   • Any existing coverage reports (*test_coverage*)
   • Architecture docs for understanding component boundaries

2. Identify the scope — From $ARGUMENTS and conversation context:

   • If a specific feature or user story is named, scope the validation to those criteria
   • If no scope is given, validate all acceptance criteria found in .chalk/docs/
   • List every acceptance criterion with its source document and ID
