Description

Two fixes, both from watching the gate run on #920 after a real approval.

1. Don't re-ask when the approval already stands

With the approval on file, a later push still posted "needs a decision", added awaiting-breaking-approval, and then the verdict took both back seconds later:

lerian-studio added the   awaiting-breaking-approval label   now
lerian-studio removed the awaiting-breaking-approval label   now

The reuse logic worked — the Environment was skipped and nobody was asked — but the request step ran anyway, because it checked whether a breaking change exists and not whether it had already been approved. The step immediately before it had just worked that out.

One condition on the step. The comment now goes straight to ✅ Breaking change approved with no flicker.

2. Link the decider instead of bolding them

- Approved by **carol**.
+ Approved by [@carol](https://github.com/carol).

Reads as the @name people expect and is clickable, without notifying. The person being named is the one who just acted, so a mention would tell them what they already know — the same reasoning already applied to the reviewer list in the waiting comment.

Type of Change

  • feat: New workflow or new input/output/step in an existing workflow
  • fix: Bug fix in a workflow (incorrect behavior, broken step, wrong condition)
  • perf: Performance improvement (e.g. caching, parallelism, reduced steps)
  • refactor: Internal restructuring with no behavior change
  • docs: Documentation only (README, docs/, inline comments)
  • ci: Changes to self-CI (workflows under .github/workflows/ that run on this repo)
  • chore: Dependency bumps, config updates, maintenance
  • test: Adding or updating tests
  • BREAKING CHANGE: Callers must update their configuration after this PR

Breaking Changes

None. One condition on an existing step, and presentation in the comment.

Testing

  • YAML syntax validated locally
  • Triggered a real workflow run on a caller repository using @this-branch or the beta tag
  • Verified all existing inputs still work with default values
  • Confirmed no secrets or tokens are printed in logs
  • Checked that unrelated workflows are not affected

Both behaviours were observed live on #920, which by then had a genuine approval from a g_github_devops reviewer. That run also confirmed the parts this PR does not change:

Approve Breaking Change after the extra commit skipped
New deployment queued none
Approval record <!-- breaking-change-approved: b553ad67939c03f4 run=38967637198 -->

And #906 confirmed the rejection half: comment turned ⛔ Breaking change rejected, the PR closed itself, breaking-change stayed, awaiting-breaking-approval went.

Two tests added. The standing-approval condition is verified by mutation — removing it fails the test. The decider links are checked on the rendered comment, including that no bare @name survives outside link text.

Caller repo / workflow run: #920

Related Issues

Seen on #920. With the approval already on file, the run still posted
"needs a decision", added awaiting-breaking-approval, and the verdict
removed both seconds later. The timeline showed the label going on and
off for a decision that was never in question.

The request step checked whether a breaking change exists, but not
whether it had already been approved — which the previous step had just
worked out. One condition.

Also links the decider instead of bolding them: `Approved by
[@Carol](https://github.com/carol)`. It reads as the @name people expect
and is clickable, without notifying — the person named is the one who
just acted, so a mention would tell them what they already know. Same
reasoning already applied to the reviewer list.

Walkthrough

The workflow skips a breaking-change approval request when prior approval is recorded. Approved and rejected reporter comments now display reviewer names as profile links. Regression tests cover the workflow condition and rendered comments.

The workflow skips the approval-request step when prior approval is recorded. A regression test checks the step condition.
Link reviewer names in comments
src/notify/breaking-change-approval-reporter/action.yml, src/validate/breaking-change-guard/test-workflow.py
Approved and rejected messages use profile links for reviewer names. The reporter trims comma-separated names, skips empty entries, and uses “a reviewer” when no names remain. Tests check the rendered links.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to 62e4a

Approved and rejected comments can still notify linked deciders, contrary to the stated intent, and the API-unreadable rejection fallback can show a misleading profile link. These bounded issues make the PR mergeable with owner awareness, though both should be corrected for the reporter behavior to match its intent.

Explanation

The description follows the repository template, explains both behavior changes, identifies the fix type, states that there are no breaking changes, and documents testing and a caller workflow run. The Related Issues section is empty, but this is non-critical because no issue is explicitly referenced.

This comment was marked as resolved.

From the CodeRabbit review on #921. The no-bare-mention check asserted
that each `@name` was preceded by `[`, which a bare `[@Carol]` with no
target satisfies — bracketed, unlinked, and notifying nobody only by
accident. The separate assertion proved one valid link existed
somewhere, not that every occurrence was one.

Both checks now delete the complete `[@name](url)` links and require
nothing to remain, so every occurrence has to be a real link.

Applied to the reviewer-list test too, which had the identical weakness
and was not flagged. Verified by breaking the link into `[@name] (url)`:
two subtests fail where the old form passed.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not prefix linked deciders with @.

GitHub treats @login inside a Markdown link as a mention in pull-request comments. An eligible approver or rejecter can therefore receive a notification. This conflicts with the no-notification intent.

🐛 Suggested fix
-            out="${out:+$out, }[@${person}](${SERVER_URL}/${person})"
+            out="${out:+$out, }[${person}](${SERVER_URL}/${person})"

src/notify/breaking-change-approval-reporter/action.yml:188-199
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve the generic rejection fallback

When the approval API is unreadable, the workflow passes REJECTERS="a reviewer". link_people() removes spaces before building the profile URL, so the rejection comment can render [@areviewer](${SERVER_URL}/areviewer) instead of a reviewer.

Preserve this fallback as plain text at the helper boundary.

Suggested fix
          while IFS= read -r person; do
-            person=$(printf '%s' "$person" | tr -d ' ')
             [ -z "$person" ] && continue
+            if [ "$person" = "a reviewer" ]; then
+              out="${out:+$out, }$person"
+              continue
+            fi
+            person=$(printf '%s' "$person" | tr -d ' ')
             out="${out:+$out, }[@${person}](${SERVER_URL}/${person})"
