Keep advisory checks off the critical path

Genuinely advisory checks (a bundle-size comment, a preview deploy, a non-blocking lint annotation) don't rerun on every push and don't gate the merge. They run once per PR, or post asynchronously, so they inform without adding to the wait. Real tests and build validation stay on every push, for those, the lever is to make them faster, not to stop running them.12

# A size-diff comment is advisory: run it on open/ready, not on every push
on:
  pull_request:
    types: [opened, ready_for_review]   # note: no "synchronize"

The advisory check reruns on every push and sits on the critical path with no gating value.

on:
  pull_request:   # the size-diff comment reruns on every push and sits on
                  #   the critical path, even though no one merges on it

The slowest check holding up a PR is sometimes one that isn't even required to merge. If it's purely advisory, running it on every push is friction with no gating value. The critical distinction: a non-required check that runs real tests or validates a build is still load-bearing developer signal, de-scoping that hides failures. Only narrow checks whose output is genuinely advisory, and if you can't confirm a check is non-required (branch-protection data is unreadable), leave it alone.

Hand this prompt to your coding agent (Claude Code, Cursor, and the like) to audit and fix this practice in your own repo.

Inspect this repo's .github/workflows for a check that sits high on the PR critical path but is purely advisory (a bundle-size comment, a preview deploy, a non-blocking annotation) and is not required to merge. For a genuinely advisory check, narrow its trigger so it does not rerun on every push (for example `types: [opened, ready_for_review]` with no `synchronize`), or make it post asynchronously. Do NOT de-scope any check that runs tests, validates a build, feeds a required aggregator, or whose required status you cannot confirm: for a real gate the fix is to make it faster, not to stop running it. Show me the diff and open a PR rather than applying it blindly.
