How to catch lost tests or CI between two snapshots with Audit Repo

Compare two audit snapshots to surface new large files, new sensitive filenames, or tests and CI that disappeared.

Who it is forA tech lead who wants a quick regression check on repository hygiene before a release.

The problemRepository hygiene erodes quietly between releases.

The outcomeA Markdown diff of meaningful changes with high-confidence attention items.

What you need first

  • Python 3.10 or newer
  • Codex for the skill workflow (the scripts run standalone)

Steps

  1. Save a baseline JSON with the collector before changes
  2. Save a second snapshot as after.json later
  3. Run python scripts/compare_repo_signals.py before.json after.json --format markdown
  4. Investigate each attention item

Prompt for your agent

Using 1838904818/audit-repo, compare <before.json> and <after.json> with `python scripts/compare_repo_signals.py before.json after.json --format markdown`. List every attention item and confirm whether CI or tests were lost.

Caveat. Snapshots are only comparable when taken with the same scan mode and scope.
