Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The new issue-labeling workflow can still modify issues marked not to be automated when manually dispatched. This is a bounded correctness risk; the PR is otherwise mergeable with explicit owner awareness and should add the opt-out check. Sequence Diagram(s)sequenceDiagram

Pull Request Overview
This PR establishes a robust, shell-only label synchronization and issue triage system. While the implementation avoids external dependencies as required, there are several concerns regarding maintainability and correctness. Most notably, all required test scenarios (conventional commit prefixes, bracket tags, human classification preservation) are currently missing automated verification.
Additionally, the core classification logic in .github/scripts/classify-issue.jq is complex and lacks any coverage, making it a high-risk component for regression. There is also a discrepancy between the PR description and the file diff concerning the .github/workflows/actions.lock file; if the lock is strictly enforced in this environment, the workflow may fail on execution. Several improvements are suggested for the synchronization script to improve performance and logging visibility.
About this PR
- The PR description mentions that workflows were added to
.github/workflows/actions.lock, but these changes are missing from the diff. This may cause startup failures in environments where the lock is strictly enforced. - Comments in
classify-issue.jqreference atests/test-classifier-parity.pyscript, but no test files were included in this PR. Given the complexity of the regex-based triage, automated tests are essential.
Test suggestions
- Classification of issue via conventional commit prefix (e.g., 'feat: ...')
- Classification of issue via bracket tags (e.g., '[p0] ...')
- Preservation of human classification (ensure classifier doesn't add a 'bug' type if issue is already labeled 'enhancement')
- Silent failure mode (ensure no labels are output if title is ambiguous and lacks a type)
- Label sync creates new labels and updates colors/descriptions for non-frozen labels
- Label sync ignores modifications to labels listed in the 'frozen' array
- Automated verification of English pluralization and verb tense changes in JQ keyword matching
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classification of issue via conventional commit prefix (e.g., 'feat: ...')
2. Classification of issue via bracket tags (e.g., '[p0] ...')
3. Preservation of human classification (ensure classifier doesn't add a 'bug' type if issue is already labeled 'enhancement')
4. Silent failure mode (ensure no labels are output if title is ambiguous and lacks a type)
5. Label sync creates new labels and updates colors/descriptions for non-frozen labels
6. Label sync ignores modifications to labels listed in the 'frozen' array
7. Automated verification of English pluralization and verb tense changes in JQ keyword matching
Low confidence findings
- The label synchronization script uses a hardcoded 0.4s sleep for rate limiting. While functional, this may be inefficient for larger label sets compared to utilizing the GitHub API's native burst capabilities or conditional requests.

⚪ LOW RISK
Suggestion: Avoid suppressing stderr for label management commands. Allowing stderr to reach the logs will improve observability for API errors (e.g., rate limits or validation errors) without changing the logic flow.

⚪ LOW RISK
Suggestion: Piping the $existing labels string to awk inside the loop is inefficient ($O(N*M)$). For better performance, write the existing labels to a temporary file before the loop and update awk to read from that file.

⚪ LOW RISK
Nitpick: Keywords ending in non-alphanumeric characters (e.g., docs/) lack trailing word boundaries in the generated regex. This may lead to false positives on strings like internal-docs/. Verify if this broad matching is intended.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Respect the status:do-not-automate opt-out.
At Line 82, HAVE can contain status:do-not-automate, but the workflow continues to gh issue edit. The taxonomy defines this label as an instruction for bots and sweeps not to touch the issue. A manual dispatch can therefore still add automated labels.
Exit before classification when this label is present.
Proposed fix

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.
