qa-coverage-gate
Test coverage delta gate. Runs the project's coverage tooling, computes per-file coverage change between the current branch and the base branch, and blocks CI if changed files drop below a configurable threshold. For files below threshold, generates LLM-suggested test stubs targeting the specific uncovered lines. Env vars: COVERAGE_THRESHOLD, COVERAGE_COMPARE_BRANCH, COVERAGE_GENERATE_STUBS. (qa-agentic-team)
