Pull request overview
This PR reduces the test-coverage-reporter agentic workflow’s token/runtime footprint by shrinking the prompt context and trimming workflow setup overhead, while keeping the coverage-reporting outcome the same.
Changes:
- Switch the workflow engine model to
summarizationand remove prompt instructions that require injecting the full prebuiltDISCUSSION_BODYinto agent context. - Reduce the per-file coverage table cap from 80 rows to 20 to shrink generated discussion content.
- Add an npm cache restore step and replace full unshallow fetch with a time-bounded
git fetch --shallow-since="7 days ago" --no-tags origin HEAD.

| .github/workflows/test-coverage-reporter.md | Updates the source workflow frontmatter, adds npm cache restore, shrinks the coverage table, adjusts git fetch strategy, and rewrites agent instructions to compose the final discussion without full DISCUSSION_BODY injection. |
| .github/workflows/test-coverage-reporter.lock.yml | Regenerates the locked workflow to reflect the new model, cache restore, fetch strategy, table cap, and prompt-context changes. |
| .github/aw/actions-lock.json | Removes pinned entries for github/gh-aw-actions/setup* versions from the action lock mapping. |
