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 labelling for newly opened and reopened issues based on their titles and existing labels.
    • Added tools to keep the repository’s label set aligned with its central label registry.
    • Labels are applied conservatively without removing or overriding existing labels.
  • Improvements

    • Added manual and scheduled options for refreshing repository labels.
    • Protected labels remain unchanged during synchronisation.

Walkthrough

Adds a label taxonomy, generated registry, jq classifier, issue triage workflow, and repository label synchronisation workflow. The classifier derives labels from issue titles and existing labels. The workflows apply additive labels and reconcile repository label metadata.

Changes

Issue labelling automation

Layer / File(s) Summary
Label taxonomy and registry
.github/label-classifier.json, .github/labels.json
Defines title, bracket, keyword, signal, tier, precedence, valid type, frozen-label, colour, and description metadata.
Issue title classification
.github/scripts/classify-issue.jq
Normalises issue titles, matches prefixes, bracket tags, and keywords, enforces tier limits, and excludes existing labels.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened, reopened, or manually selected issues and applies valid suggestions with gh issue edit.
Repository label synchronisation
.github/workflows/labels.yml
Creates missing labels, updates colour or description drift, and skips frozen labels on scheduled or triggered runs.

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

Merge Risk: 🟡 Moderate · up to fd7ed

The PR adds automated label synchronization and issue triage, but the current implementation can misclassify issues when label reads fail and can report synchronization success while labels remain missing or stale. These bounded correctness and integration risks should be fixed or explicitly accepted before merging.

Create missing frozen canonical labels.

Line 256 prevents the label synchronisation workflow from creating security. If a repository does not already define security, triage removes that classifier result before it applies labels. Create frozen labels when absent, but continue to skip metadata edits for existing frozen labels.

Serialise label synchronisation runs.

Two runs can process different revisions of .github/labels.json at the same time. An older run can finish after a newer run and restore stale colour or description metadata. Add a repository-scoped concurrency group.

Fail the workflow when synchronisation cannot complete.

Line 45 suppresses fetch and decoding errors, and the empty-file check treats them as “nothing to do”. Because set -e is absent, failures from the existing-label request and jq process substitutions also do not stop the script. The create and edit branches ignore non-zero statuses.

A rate-limit, permission, malformed JSON, or transient API failure can therefore leave labels unsynchronised while the workflow succeeds. Distinguish an expected missing file from operational errors, then fail on unexpected fetch, parse, list, create, and edit failures.

GitHub CLI gh label create edit repository selection current directory GH_REPO -R documentation

💡 Result:

The GitHub CLI (gh) uses the current directory's local Git configuration to identify the target repository for commands like gh label create [1][2]. When you execute gh label create, the CLI automatically detects the repository by looking at your configured Git remotes [1][3]. If your directory is a Git repository, gh will attempt to use the associated remote as the default [4]. If you have multiple remotes or are in a directory where the repository is not automatically detected, you can explicitly set or manage the default repository using the following methods: 1. Interactive Configuration: Run the command gh repo set-default without arguments [5][2]. This opens an interactive picker allowing you to select which of your configured remotes should be treated as the default for that directory [3][2]. 2. Explicit Setting: Use gh repo set-default owner/repo to bind a specific repository path to the current directory [5][2]. This updates your local.git/config file, adding a gh-resolved setting to the corresponding remote [6]. 3. Environment Variable (GH_REPO): For scenarios where you are not working within a local Git repository, you can override the target repository by setting the GH_REPO environment variable [7]. This variable takes the format [HOST/]OWNER/REPO and forces gh to operate on that specific repository regardless of the current directory [7]. The setting made via gh repo set-default is persistent and local to the repository; it modifies the.git/config file of the directory where it was run [6]. If you encounter errors, ensure that your repository has at least one remote configured that corresponds to a valid GitHub repository [3].

Give gh label an explicit repository.

This workflow does not check out the repository or set GH_REPO. Therefore, gh label create and gh label edit have no repository context and can fail. Add -R "$GITHUB_REPOSITORY" to both commands.

Pull Request Overview

This PR introduces a canonical label taxonomy and an automated triage system. While the implementation aligns with the goal of being additive and avoiding external actions, there are significant gaps in meeting the defined acceptance criteria. Most notably, the requirement to update .github/workflows/actions.lock is unfulfilled despite being mentioned in the PR description.

The technical approach uses jq to bypass Python bans, resulting in complex regex-based logic in .github/scripts/classify-issue.jq. This file is identified as high-risk due to its complexity and a lack of unit tests or validation against the parity suite mentioned in its own documentation. Additionally, the workflows rely on fetching script logic via the GitHub API, which introduces runtime dependencies on the availability of the GITHUB_SHA at execution time.

While Codacy reports the code is up to standards, the missing lockfile and the lack of automated verification for the classification logic are issues that should be addressed prior to merging.

About this PR

  • The PR description states that the two new workflows were added to .github/workflows/actions.lock, but this file is missing from the code changes. This is a requirement for avoiding external action dependency issues.
  • The workflows fetch their own logic via gh api and base64 decoding rather than using standard checkouts. While this bypasses lockfile requirements for external actions, it adds significant complexity and creates a dependency on the GITHUB_SHA being accessible via the API at runtime.

Test suggestions

  • Classification of issue title with conventional commit prefix (e.g., 'feat: something')
  • Classification of issue title with bracketed tag (e.g., '[p1] something')
  • Keyword area detection for specific domains (e.g., 'agda' -> 'proofs')
  • Verification that classifier respects and does not duplicate labels in tiers already populated by humans
  • Label sync workflow correctly updates color and description drift for existing labels
  • Label sync workflow ignores labels explicitly marked as 'frozen'
  • Unit tests for kwrx regex generation logic in .github/scripts/classify-issue.jq (specifically 'at' and 'ment' suffixes)
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classification of issue title with conventional commit prefix (e.g., 'feat: something')
2. Classification of issue title with bracketed tag (e.g., '[p1] something')
3. Keyword area detection for specific domains (e.g., 'agda' -> 'proofs')
4. Verification that classifier respects and does not duplicate labels in tiers already populated by humans
5. Label sync workflow correctly updates color and description drift for existing labels
6. Label sync workflow ignores labels explicitly marked as 'frozen'
7. Unit tests for `kwrx` regex generation logic in `.github/scripts/classify-issue.jq` (specifically 'at' and 'ment' suffixes)

🟡 MEDIUM RISK

This JQ implementation contains complex logic that replaces the original Python classifier. Since this script is used for automated triage across the estate, ensure that any logic changes (such as the inflection handling in kwrx) are validated against the tests/test-classifier-parity.py suite mentioned in the file header to avoid misclassifying issues.

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.

Stop when the existing-label read fails.

HAVE='[]' treats an API failure as proof that the issue has no labels. An issue with enhancement can therefore receive bug when its title matches a fix: rule. This creates conflicting labels in a max-1 tier during an API or rate-limit failure.

Exit successfully when the label read fails. Use [] only after a successful empty response.

Add a retry after label synchronisation

If issue triage runs before label synchronisation creates the labels, DEFINED is empty and the workflow exits successfully without labelling the issue. .github/workflows/labels.yml has no automatic retry trigger. Add a post-synchronisation retry or ensure synchronisation completes before triage runs.

Fail when a label mutation fails.

If one mutation fails after another succeeds, failed is greater than zero but created + updated is also greater than zero. The condition at Line [101] is then false, and Line [105] reports success although the registry is incomplete. The triage workflow filters suggestions against labels returned by gh label list (Lines 50-103 of .github/workflows/label-triage.yml), so a failed label creation can cause that suggestion to be dropped. Exit non-zero when failed > 0, or retry failed mutations before returning success.
