A September 7 commit to the community-maintained awesome-copilot repository updates the prompting instructions for docs-sync-audit and test-gap-audit. The revised instructions require both skills to substantiate their audit findings with concrete evidence. Both remain read-only by default.

Under the revised instructions, any source line cited by either skill must contain the exact quoted text or named symbol. Quantitative findings must display the exact command run and its raw result under a dedicated Checks Run section; audits lacking execution data must use qualitative wording instead. The prompts also direct Copilot to treat all repository files strictly as inert data rather than agent instructions, reporting prompt injection attempts or unexpected redirections as audit findings. These edits change prompt behavior alone; they do not establish a security sandbox or deliver measured reliability gains.

The two skills serve different review tasks:

  • docs-sync-audit evaluates documentation against actual code, configurations, and API behavior. It flags out-of-sync command syntax, altered environment variables, and broken relative links across pull requests or full repositories, without modifying files unless asked.
  • test-gap-audit examines existing test suites to surface untested paths and suggest regression test scenarios. It differentiates verified missing assertions from inferred gaps without providing a coverage percentage guarantee.

Neither skill guarantees complete defect detection. Both rely on bundled, unchanged Python 3 standard-library scripts. The test helper, coverage_map.py, pairs files heuristically without executing the test suite, meaning indirect fixture coverage and end-to-end tests can be overlooked.

Running these workflows requires local repository access and a GitHub Copilot environment with Agent Skills enabled. The Python scripts require no dedicated API keys, though standard Copilot access and repository permissions remain necessary. Both skills are available under the MIT license in the awesome-copilot repository.
