feat(labels): estate label tooling + auto-triage for new issues - #143
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a versioned label taxonomy, a jq classifier, an issue triage workflow, and a label synchronisation workflow. The classifier uses title rules, bracket tags, keywords, and signals while preserving existing max-one classifications. ChangesGitHub label automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new label automation can apply unmerged branch definitions, edit protected labels when required data is missing, and add conflicting type labels during concurrent runs. Merge should wait for these bounded correctness and repository-integrity risks to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Pull Request Overview
The pull request successfully implements an estate-wide label management and triage system using JQ and Shell, adhering to the requirement of avoiding Python dependencies. While Codacy reports the PR is up to standards, the review has identified critical logic flaws in the issue classification engine and shell argument handling that will cause the automation to fail or produce incorrect results.
Specifically, the JQ-based classifier lacks error handling for regular expression captures, which will cause the script to terminate early on standard issue titles. Additionally, the label application logic is vulnerable to word-splitting, which will fail for any label containing spaces. These issues, combined with the omission of the referenced test suite (tests/test-classifier-parity.py), represent a significant reliability risk that must be addressed before merging.
About this PR
- The codebase references 'tests/test-classifier-parity.py' as the verification source for the jq logic, but this file was not included in the PR. Given the complexity of the regex logic and the high-risk nature of the uncovered scripts, please include the test suite to ensure long-term maintainability.
- There is a conflict between the triage goal of 'never overriding human classification' and the sync workflow's behavior of reverting manual color/description changes. A systemic 'frozen' list is a good mitigation, but ensure this trade-off is acceptable for the estate.
Test suggestions
- Found recommended test scenario: Classifier correctly maps title prefixes (e.g., 'feat:') to type labels (e.g., 'enhancement').
- Found recommended test scenario: Classifier correctly maps bracket tags (e.g., '[p0]') to priority labels.
- Found recommended test scenario: Classifier detects keywords (e.g., 'security') and adds area labels.
- Found recommended test scenario: Classifier respects existing human labels by refusing to add a second label in a 'max: 1' tier (e.g., type, priority).
- Found recommended test scenario: Classifier returns an empty set when no confident 'type' label can be determined.
- Found recommended test scenario: Label sync workflow updates color and description for existing labels unless they are in the 'frozen' list.
- Found recommended test scenario: Label sync workflow creates missing canonical labels even if they are marked as 'frozen'.
- Missing: Integration test for issue titles containing spaces to verify fix for shell word-splitting.
- Missing: Unit test for JQ script with non-matching titles to verify
try/catcherror handling.

🔴 HIGH RISK
The capture for conventional commit prefixes will raise an error if the title doesn't match the pattern, preventing the script from reaching keyword-area and signal detection logic. Wrap this in a try block.

🔴 HIGH RISK
The capture function raises an error if the input string does not match the provided regular expression. This causes the entire filter to fail and terminate, breaking triage for issues without bracketed tags. Wrap this logic in a try ... catch or use test before capture to ensure the script proceeds to keyword-based classification.

🟡 MEDIUM RISK
Command substitution $(...) combined with printf %q does not safely handle word splitting for arguments containing spaces (e.g., 'good first issue'). This will cause the gh command to interpret parts of the label as separate arguments. Use a Bash array to build the arguments instead.

Suggestion: Suppressing stderr with 2>/dev/null in the jq call prevents the workflow from logging syntax errors or logic failures. If the ruleset or script is corrupted, the triage will fail silently. Remove the suppression to allow for easier debugging.

⚪ LOW RISK
Suggestion: The sync workflow will overwrite manual color/description customizations for canonical labels. Ensure that any labels requiring human-managed aesthetics are added to the 'frozen' array in .github/labels.json to prevent monthly drift repair from overriding them.

⚪ LOW RISK
Nitpick: The classification engine enforces a mandatory 'type' label (e.g., bug, enhancement) as a gate for applying any labels. This might lead to missed automated tagging (like 'area: security') for issues with non-standard prefixing. Consider allowing 'area' or 'priority' labels to be applied even when a 'type' isn't confidently identified.
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.

Serialise triage runs for each issue.
Without per-issue concurrency, two runs can read an empty HAVE, classify different titles as different type labels, and add both with gh issue edit. This violates the type tier maximum of one. Add a concurrency group keyed by repository and issue number, with cancel-in-progress: false.

🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win
Add a concurrency group.
Three triggers feed this workflow. A push and the monthly schedule can overlap, and two runs then call gh label create for the same missing label. One run records a create failure for a label that already exists, which pollutes the failed count and can mask a real misconfiguration. A concurrency group serialises the runs.

Limit the push trigger to the default branch.
The push trigger has no branches filter. A push to any branch that touches .github/labels.json runs the sync, and line 51 reads the payload at $GITHUB_SHA. Label definitions from an unmerged branch are then applied to the live repository. Restrict the trigger to the default branch.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Fail loudly when .frozen is missing from the payload.
jq -r '.frozen[]' exits non-zero when .frozen is absent, but mapfile reads from a process substitution and the step does not use set -e. FROZEN then stays empty, the check at line 64 never matches, and the block at line 83 never runs. Every frozen label becomes eligible for gh label edit, which is the exact behaviour the header comment at lines 7-9 promises to prevent. .github/labels.json is generated, so a change to the generator can remove or rename the key without any signal.
