Owner

Ships the canonical label set and the classifier that labels newly-filed issues.

Additive only — never removes a label, never overrides a human's classification, silent when unsure, 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 none.

See docs/LABELS.adoc in hyperpolymath/.git-private-farm.

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • New Features

    • Added automatic issue labelling based on issue titles, existing labels, and configured classification rules.
    • Added support for synchronising the repository’s label set, including preserving protected labels.
    • Added a comprehensive label taxonomy covering type, area, priority, status, metadata, and scope.
  • Improvements

    • Issue labelling is additive-only and remains silent when classification is inconclusive.
    • Label synchronisation can run manually, monthly, or when label configuration changes.

Walkthrough

The change adds a canonical label taxonomy, a jq issue classifier, and workflows that apply issue labels and synchronise repository label metadata.

Changes

Issue label automation

Layer / File(s) Summary
Label taxonomy and classification rules
.github/labels.json, .github/label-classifier.json
Defines 39 labels, frozen labels, title-prefix and bracket-tag rules, keyword signals, tier limits, supported types, and precedence rules.
Issue title classifier
.github/scripts/classify-issue.jq
Normalises issue titles, matches classification rules and signals, enforces tier limits, and emits canonical labels that are not already assigned.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened, reopened, or manually selected issues. It filters suggestions against repository labels and applies labels without removing existing labels.
Label synchronisation workflow
.github/workflows/labels.yml
Creates missing labels, updates non-frozen drift, preserves existing frozen labels, reports mutation results, and handles partial failures.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to ba411

The new label automation may silently skip synchronization for invalid configuration, fail when runs overlap, and label issues that explicitly opt out of automation. These are bounded merge-readiness risks that should have explicit owner awareness or follow-up.

Pull Request Overview

This PR implements a canonical labeling system and automated triage using JQ-based logic, successfully avoiding external dependencies as required. However, several functional and reliability issues must be addressed before merging.

Most critically, the triage workflow contains a shell word-splitting bug that will cause the automation to fail when handling label names with spaces (e.g., 'good first issue'). Furthermore, while the system is designed to be additive-only and respectful of human classification, there are no automated tests provided to verify the complex JQ logic against the intended classification rules. The Codacy analysis indicates the project is up to standards, but these logic and execution risks are not captured by static analysis.

About this PR

  • The classifier logic implemented in JQ is complex but lacks associated tests. It is recommended to include a test suite or a mock corpus to verify that bracket tags, prefixes, and keyword inflections match as expected before deployment.

Test suggestions

  • Classification via bracket tags (e.g., [p0], [estate])
  • Classification via conventional commit prefixes (e.g., feat:, fix:)
  • Classification via keyword detection with inflection support (e.g., 'tests' matching 'test')
  • Prevention of multiple type labels (max-1 tier enforcement)
  • Label sync workflow correctly creates missing labels and updates drifting colors/descriptions
  • Label sync workflow ignores labels listed in the 'frozen' array
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classification via bracket tags (e.g., [p0], [estate])
2. Classification via conventional commit prefixes (e.g., feat:, fix:)
3. Classification via keyword detection with inflection support (e.g., 'tests' matching 'test')
4. Prevention of multiple type labels (max-1 tier enforcement)
5. Label sync workflow correctly creates missing labels and updates drifting colors/descriptions
6. Label sync workflow ignores labels listed in the 'frozen' array
Low confidence findings
  • The automated triage workflow fetches rules via the GitHub API and pipes them to base64 -d. Be aware that this approach may fail if the JSON configuration files eventually exceed the 1MB API limit for single-file content.
  • The PR description mentions updates to .github/workflows/actions.lock, but this file is missing from the current diff. Ensure the lock state is updated to maintain security posture.

🟡 MEDIUM RISK

The unquoted subshell expansion $(printf ...) for the gh issue edit command will fail if a label name contains spaces (e.g., 'good first issue'). Bash performs word splitting on the result, breaking the escaped label names into separate arguments. Replace the unquoted subshell expansion in the gh issue edit command with a robust bash array-building loop (using apply_args+=('--add-label' "$label")) to correctly handle label names containing spaces.

⚪ LOW RISK

Suggestion: The migration keyword uses a Unicode arrow (→), but common developer input and the description in labels.json use ->. Consider adding an ASCII variant to the keyword list to improve match rates.

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.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Respect status:do-not-automate before emitting labels.

If $have contains status:do-not-automate, classify can still emit type and area labels. The triage workflow then changes an issue that explicitly opts out of bot and sweep changes. Return an empty result before the normal output gate.

Proposed fix

Serialise label synchronisation runs.

A manual run can overlap with a push or scheduled run. Both runs can read the same missing label, then one gh label create succeeds and the other fails because the label now exists. The second run exits with status 1 when it made no other mutation.

Add workflow-level concurrency and retain queued runs.

Fail when the payload has an invalid shape.

jq runs in process substitutions on Lines 55 and 94. Its failure does not fail this script. If .github/labels.json is malformed or lacks the expected arrays, the workflow can report created=0 updated=0 and exit successfully without synchronising labels.

Validate the payload with jq -e before these reads. Exit non-zero when validation fails.

Proposed fix
           [ -s "$PAYLOAD" ] || { echo "no .github/labels.json - nothing to do"; exit 0; }
+          jq -e '(.frozen | type == "array") and (.labels | type == "array")' \
+            "$PAYLOAD" >/dev/null \
