feat(labels): estate label tooling + auto-triage for new issues - #21
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a generated label taxonomy, a jq classifier, an issue triage workflow, and a label synchronisation workflow. The classifier parses title signals, respects existing and frozen labels, and enforces tier limits. The workflows fetch repository data and apply additive labels or reconcile label definitions. ChangesLabel automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new triage workflow can add conflicting labels when existing labels cannot be read or when another label change occurs concurrently, and failures may leave labels unsynchronised while appearing successful. This is a bounded correctness risk that should have explicit owner follow-up before or immediately after merge. Sequence Diagram(s)sequenceDiagram

Make synchronisation failures fail the job.
Because the step does not use set -e, || true masks fetch and decode failures, and the && branches mask failed gh label create and gh label edit calls. The job can therefore succeed with missing or stale labels. Handle an expected missing file separately, but exit non-zero for other fetch, decode, and write failures.

Pull Request Overview
This PR introduces a canonical label taxonomy and an automated triage system. While the implementation follows the 'additive-only' requirement and avoids external actions to maintain drift-resistance, there are key operational concerns. Codacy results indicate the PR is up to standards, but internal analysis reveals that the most complex logic in the triage system—the jq-based classifier—is entirely uncovered by tests. There is also an implementation gap regarding the protection of 'frozen' labels, as the current diff does not explicitly show the exclusion logic described in the requirements. Most importantly, the absence of changes to .github/workflows/actions.lock may block these new workflows from running if repository security policies are strictly enforced.
About this PR
- The PR description states that
.github/workflows/actions.lockwas updated to include the new workflows, but these changes are not present in the PR. If the repository enforces workflow locking, this will cause a 'startup_failure' upon merge. - The PR introduces a complex jq-based regex engine for classification in
.github/scripts/classify-issue.jqwithout including the parity test suite (tests/test-classifier-parity.py) mentioned in the script's comments. This makes the system difficult to validate safely.
Test suggestions
- Conventional commit prefixes (e.g., 'fix:', 'feat:') result in correct 'type' and 'area' labels.
- Bracket tags (e.g., '[p0]') are correctly mapped to priority labels.
- Classifier identifies and respects existing tier labels (e.g., existing 'bug' label prevents adding 'enhancement').
- kwrx regex logic correctly handles alphanumeric keyword suffixes like 'tests' or 'implementing'.
- Label sync workflow correctly identifies color/description drift and updates labels without touching frozen ones.
- Unit tests for complex regex logic in .github/scripts/classify-issue.jq to address coverage gaps.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Conventional commit prefixes (e.g., 'fix:', 'feat:') result in correct 'type' and 'area' labels.
2. Bracket tags (e.g., '[p0]') are correctly mapped to priority labels.
3. Classifier identifies and respects existing tier labels (e.g., existing 'bug' label prevents adding 'enhancement').
4. kwrx regex logic correctly handles alphanumeric keyword suffixes like 'tests' or 'implementing'.
5. Label sync workflow correctly identifies color/description drift and updates labels without touching frozen ones.
6. Unit tests for complex regex logic in .github/scripts/classify-issue.jq to address coverage gaps.

🟡 MEDIUM RISK
Add an error check to the existing label fetch to prevent the sync from attempting to recreate the entire taxonomy if the API call fails. If the gh api call at line 51 fails, the script should exit or skip the loop rather than proceeding with an empty list.

⚪ LOW RISK
Nitpick: This logic ensures taxonomy integrity by preventing 'orphaned' area labels. Ensure users are encouraged to use conventional commit prefixes (e.g., fix:, feat:) to maximize the auto-triage hit rate, as issues without a clear type will remain untriaged.

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.

Fail closed when reading existing labels.
If gh issue view --json labels fails, HAVE='[]' prevents .github/scripts/classify-issue.jq from locking the issue’s existing max-one tier. The workflow can then add a conflicting label with gh issue edit --add-label, which violates the additive-only contract. Exit before classification when the label read fails.

GitHub CLI gh issue edit --add-label implementation REST API conditional If-Match issue labels endpoint
💡 Result:
The GitHub CLI (gh) command gh issue edit --add-label [label_name] is a high-level wrapper that automates the process of updating issue labels via the GitHub REST API [1][2]. Implementation Details: 1. REST API Endpoint: When you execute gh issue edit --add-label, the CLI typically interacts with the Add labels to an issue endpoint (POST /repos/{owner}/{repo}/issues/{issue_number}/labels) [3][4]. This specific endpoint is designed to append new labels to an issue's existing collection rather than replacing the entire set [5][3]. 2. Conditional If-Match: The GitHub REST API's issue and label endpoints generally do not require the If-Match header for standard label additions, as this operation is designed as an additive update [5][3]. The If-Match header is typically reserved for conditional requests where you want to ensure an update only occurs if the resource's ETag matches a specific version (often used to prevent mid-air collisions on content-heavy resources like the main issue body) [6][7]. 3. CLI Abstraction: The gh CLI manages the API authentication, request formation, and handling of responses automatically [1]. Users do not need to manually specify headers like If-Match when using the CLI; it handles the necessary API calls to add or remove labels as requested by the flags [1][8]. In summary, the gh issue edit command simplifies the interaction with the underlying REST API. For adding labels specifically, it utilizes the appropriate POST endpoint, and the requirement for conditional logic like If-Match is not applicable or required for this specific label-management operation [5][3].

GitHub REST API issues add labels conditional requests If-Match ETag atomic update
💡 Result:
The GitHub REST API provides conditional request support primarily for GET requests using ETag and Last-Modified headers to optimize polling and save rate limits [1][2][3]. When a client uses the If-None-Match header with a previously received ETag, the API may return a 304 Not Modified response if the resource has not changed [1][3]. Regarding "atomic updates" for operations such as adding or setting labels on an issue, the GitHub REST API does not generally support conditional requests (e.g., If-Match for concurrency control) for unsafe methods like POST, PUT, or PATCH, unless explicitly noted in the documentation for a specific endpoint [3]. Official GitHub API documentation for issue label management does not list conditional request headers (like If-Match) as supported parameters for the Add labels (POST) or Set labels (PUT) endpoints [4][5]. Consequently, these operations are not designed to provide atomic concurrency control via ETag headers, and developers have reported that attempts to use If-Match headers with PATCH/PUT requests do not prevent concurrent updates [6]. Developers requiring strict consistency or atomic updates on GitHub resources should be aware of these API limitations [6][3].

Serialise label classification and handle the remaining race.
classify-issue.jq excludes a max-one tier only when $have already contains a label from that tier. label-triage.yml reads HAVE before it calls gh issue edit --add-label, so an intervening label change can create two labels in one tier.
Add per-issue concurrency and perform a final label read before the edit. Discard or recalculate ADD when the state changed. GitHub's add-label endpoint is additive and has no compare-and-set or If-Match update, so this reduces the race but cannot make the invariant atomic. Treat max-one enforcement as best-effort unless a reconciliation step may remove conflicts.
