Pull Request Overview
The PR implements a jq-based automated triage system that is generally up to standards according to Codacy. However, there are critical gaps that should be addressed before merging: specifically, the complete lack of unit tests for the complex regex-heavy logic in the classifier script and a shell expansion bug in the triage workflow.
While the logic appears to satisfy core requirements such as human-override protection and additive-only labeling, the absence of verification for inflection handling and tier constraints poses a maintenance risk. Additionally, the workflow contains a pattern that will fail when handling common GitHub labels containing spaces.
About this PR
- The complex regex logic in the JQ classifier is currently unverified. No unit tests were included in the PR to exercise the inflection logic or tier-exclusion rules (e.g., the 'port' vs 'portion' distinction), which represents a regression risk.
- The PR description references a Python-based parity test ('tests/test-classifier-parity.py'), which contradicts the acceptance criterion to avoid Python due to estate-wide language policies. If automated tests are implemented, they must align with the permitted technology stack.
- The workflow fetches the classifier script via 'gh api' at runtime using '$GITHUB_SHA'. This creates a dependency on API availability and token permissions for basic execution. Using a standard repository checkout is generally more robust for accessing internal scripts.
Test suggestions
- Verify 'feat:' prefix correctly maps to 'enhancement' label.
- Verify '[p0]' bracket correctly maps to 'priority:p0' label.
- Verify keyword matching with inflections (e.g., 'theorems' or 'tested' matching base keywords).
- Confirm that if an issue already has a 'type' label (e.g., bug), the classifier does not add a second 'type' label (e.g., enhancement) even if rules match.
- Verify that labels listed in the 'frozen' array are skipped during the synchronization process.
- Verify that the classifier remains silent (returns no labels) if no 'type' is identified.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify 'feat:' prefix correctly maps to 'enhancement' label.
2. Verify '[p0]' bracket correctly maps to 'priority:p0' label.
3. Verify keyword matching with inflections (e.g., 'theorems' or 'tested' matching base keywords).
4. Confirm that if an issue already has a 'type' label (e.g., bug), the classifier does not add a second 'type' label (e.g., enhancement) even if rules match.
5. Verify that labels listed in the 'frozen' array are skipped during the synchronization process.
6. Verify that the classifier remains silent (returns no labels) if no 'type' is identified.

🟡 MEDIUM RISK
Using unquoted command substitution for label arguments will break if a label name contains spaces (e.g., 'good first issue'). Use an array to safely build the command arguments instead.
Try running the following prompt in your coding agent:
Refactor the label application logic in the triage workflow to use a Bash array for building the
gh issue editcommand arguments instead of relying on unquoted command substitution.

Ships the canonical label set and the classifier that labels newly-filed issues. Additive only: it never removes a label, never overrides a human's classification, stays silent when unsure, and never fails an issue. Also adds this repo's two new workflows to .github/workflows/actions.lock as '[]'. That lock is keyed by workflow path and refuses any workflow it does not list -- a startup_failure, which produces no check run and is therefore silent. `gh actions-lock` cannot add these: it records action versions, and both workflows deliberately use no actions.

Revalidate the issue state before applying labels.
TITLE is read at Line 68 and HAVE is read at Line 82. The workflow applies ADD at Line 114 without checking that either value is still current. If a title changes or a human adds a max-1 label during this interval, the workflow can apply stale labels or add a conflicting canonical label.
Re-fetch the title and labels immediately before the final classification and write. Add a per-issue concurrency group for automated runs to prevent overlapping stale snapshots.

Serialise label synchronisation runs.
A push, a schedule, and a manual dispatch can run at the same time. Each run can read the same missing label before either creates it. One run then receives a duplicate-label error and can fail with every label mutation failed, although the other run completed the required change.

Do not treat a payload-fetch failure as an empty payload.
Line 52 discards every gh api and base64 error with || true. An API outage, expired token, or permission error then reaches Line 53 and reports a successful no-op. The repository labels remain unsynchronised without a failed workflow run.
Fail when the fetch or decode operation fails. Keep the empty-payload path only for an explicitly supported successful response.
