feat(labels): estate label tooling + auto-triage for new issues - #97
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change adds a versioned GitHub label taxonomy, a jq issue classifier, an issue triage workflow, and a scheduled label synchronisation workflow. The workflows fetch repository files at the current commit and use best-effort GitHub API operations. ChangesLabel automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new label synchronization can silently skip updates when its configuration cannot be retrieved or decoded, and overlapping runs can fail while creating the same labels. The change is otherwise mergeable, but these bounded workflow reliability risks should be addressed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

Pull Request Overview
While this PR implements a policy-compliant (non-Python, no external actions) labeling system, it lacks the necessary validation for its core logic. Codacy results are up to standards, but significant gaps exist in requirement alignment: all 6 mandatory test scenarios are currently missing. Key technical issues include a fragile TSV parsing mechanism in the label sync workflow that will fail if label descriptions contain newlines, and inefficient API usage in the triage logic that introduces unnecessary latency and potential race conditions. High-risk regex logic within the jq filters is unverified by any test suite, which is the primary blocker for merging.
About this PR
- The PR introduces complex regex-based logic for issue classification but does not include accompanying test files to verify behavior against various issue titles. Automated unit or integration tests are required to ensure the jq logic correctly identifies bug, documentation, and other types as specified in the requirements.
Test suggestions
- Verify JQ script identifies 'bug' type from a 'fix:' title prefix.
- Verify JQ script identifies 'documentation' type from a 'docs:' title prefix.
- Verify JQ script respects existing labels and does not add a second 'type' label to an issue.
- Verify labels.yml workflow creates missing labels from the taxonomy.
- Verify labels.yml workflow skips updating color/description for 'frozen' labels.
- Verify triage workflow handles GitHub API failures (e.g. 404, 500) by exiting gracefully (exit 0).
- Add unit tests for JQ regex logic within the classifier.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify JQ script identifies 'bug' type from a 'fix:' title prefix.
2. Verify JQ script identifies 'documentation' type from a 'docs:' title prefix.
3. Verify JQ script respects existing labels and does not add a second 'type' label to an issue.
4. Verify labels.yml workflow creates missing labels from the taxonomy.
5. Verify labels.yml workflow skips updating color/description for 'frozen' labels.
6. Verify triage workflow handles GitHub API failures (e.g. 404, 500) by exiting gracefully (exit 0).
7. Add unit tests for JQ regex logic within the classifier.
Low confidence findings
- The Label Triage workflow relies on fetching scripts and rules via API followed by manual base64 decoding. While this adheres to the local action-locking policy, it increases susceptibility to shell-level failures and character encoding issues compared to standard workflow structures.

🟡 MEDIUM RISK
The TSV-based parsing logic will fail for labels with multi-line descriptions. When a description contains a newline, the 'while read' loop will treat it as a new, malformed record, resulting in incomplete updates. Consider refactoring the sync to compare the local and remote datasets using jq directly.
Try running the following prompt in your coding agent:
Refactor the labels.yml workflow to process the sync logic without intermediate TSV parsing. Use jq to join the local labels.json and the gh api output to identify which labels require creation or updates.

🟡 MEDIUM RISK
Suggestion: Consolidate the retrieval of the issue title and existing labels into a single gh issue view call to improve efficiency and consistency. This avoids potential race conditions where labels change between the two API requests.
Try running the following prompt in your coding agent:
In the triage workflow, replace the separate gh issue view calls for TITLE and HAVE with a single call that fetches both fields in JSON format, then use jq to parse the results into their respective variables.

⚪ LOW RISK
Nitpick: The sleep 0.4 is unnecessarily long and significantly increases workflow duration. GitHub's API rate limits and the CLI's built-in retry mechanisms are sufficient to handle these edits at much higher speeds.

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.

GitHub Actions concurrency group cancel-in-progress false queued workflow runs same repository documentation; GitHub REST create label existing name 422
💡 Result:
GitHub Actions Concurrency and Queued Runs When you configure a concurrency group with cancel-in-progress: false, GitHub Actions protects the job or workflow currently in progress from being cancelled [1][2][3]. However, this setting does not prevent newer workflow runs from cancelling existing pending (queued) runs [2]. By default, GitHub Actions concurrency groups are limited to one in-progress run and one pending run [1][4]. If a new run is triggered while another is already queued in that same group, the older pending run is cancelled to make room for the newer one, even if cancel-in-progress is false [2]. To allow more than one run to wait in line without being cancelled, you can now use the queue property (e.g., queue: max) to support up to 100 queued runs [1][5]. GitHub REST API 422 Error for Existing Labels Receiving a 422 Unprocessable Entity error when attempting to create a label that already exists is standard behavior for the GitHub REST API [6][7]. The API enforces unique label names within a repository [6]; if a label with the specified name already exists, the server returns an already_exists error code [8][7]. To handle this programmatically, you should implement an existence check (e.g., calling the Get a label endpoint) before attempting to create the label, or use an update/edit operation if the label is already present [8]. Tools like the GitHub CLI or Terraform providers have historically managed this by attempting a get-first or catch-the-error strategy to maintain idempotency [9][8].

Serialise label synchronisation runs.
If concurrent runs read the same label snapshot before either creates a missing label, the later run can receive duplicate-name failures for every create attempt and exit 1 at lines 101–103. Add a repository-scoped concurrency group with cancel-in-progress: false.
