Review Rubric

Load this reference when reviewing current or updated efficiency work.

Use this rubric:

  • Scope discipline: only GitHub Actions guidance was loaded
  • Safety: required validation coverage was preserved
  • Token efficiency: the skill or report stayed focused on the active task
  • Measurement quality: expected and measured gains were clearly separated

If one rubric dimension is weak, call that out explicitly instead of averaging it away.

What it does

Audits GitHub Actions workflows to identify and fix waste—missing caches, over-broad triggers, duplicate job coverage, and inefficient matrix strategies. Ranks fixes by estimated CI minutes saved and validates changes against guardrails that preserve required validation and critical-path latency.

Generated from the current SKILL.md.

Frequently asked

What does this skill actually audit?
GitHub Actions workflows in `.github/workflows/` for waste sources like missing dependency caches, absent concurrency cancellation, over-broad triggers, duplicate job coverage, and expensive jobs running on every change.
Can I use this without shell or gh CLI access?
Yes. Ask the user to paste `.github/workflows/` contents and `gh run list --limit 10` output, then perform a static-only analysis based on provided files.
Does this skill recommend fixes that might break required checks?
No. The skill explicitly drops any fix that hides release, schema, migration, or shared-library validation, and flags (rather than removes) write-back jobs that run automatically.
How many fixes does this skill recommend?
Up to 3, selected from six candidate categories and ranked by estimated daily CI minutes saved. All candidates that meet audit evidence and guardrail criteria are included, up to the maximum of 3.
Can this skill validate fixes against live runs?
Yes, if gh CLI access is available. It will test path-gating and concurrency cancellation with a push on a non-protected branch; otherwise it states that live validation is not possible.
