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.

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Added automated issue labelling based on titles, prefixes, keywords and existing labels.
    • Added a standard catalogue of 35 labels covering type, area, priority, status, metadata and scope.
    • Added scheduled synchronisation to create missing labels and update label details.
    • Existing labels are preserved, while uncertain classifications are left unchanged.

Walkthrough

Added a label taxonomy, a jq issue classifier, an automatic issue-triage workflow, and a label-synchronisation workflow. The workflows use GitHub API calls and apply additive label changes.

Changes

Label automation

Layer / File(s) Summary
Label taxonomy and catalogue
.github/label-classifier.json, .github/labels.json
Defines title and bracket mappings, keyword signals, label tiers, limits, precedence, supported types, frozen labels, and the canonical label catalogue.
Issue classification logic
.github/scripts/classify-issue.jq
Normalises issue titles, resolves explicit prefixes, detects taxonomy signals, enforces tier limits, and emits labels that are not already present.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened or reopened issues, supports manual issue selection, filters suggestions against defined labels, and adds valid labels without removing existing labels.
Label catalogue synchronisation
.github/workflows/labels.yml
Creates missing labels, updates colour or description differences, skips frozen labels, and reports synchronisation counts on manual, push, or monthly triggers.

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

Merge Risk: 🟡 Moderate · up to 19ea0

The PR adds automated label synchronization and issue triage, but the current workflows can silently fail to create labels, apply conflicting labels after a read failure, or leave new issues unlabeled when canonical labels are missing. These bounded correctness and automation failures should be fixed or explicitly accepted before merging.

Frozen names rest untouched through the night

GitHub CLI gh label create edit repository resolution GH_REPO current directory git remote GITHUB_REPOSITORY

💡 Result:

The GitHub CLI (gh) determines the target repository for commands by inferring it from the current working directory's Git remotes [1]. When you execute a command like gh label create or gh label edit, the CLI automatically resolves the repository context from the local Git configuration [1]. You can override this automatic resolution in two ways: 1. Environment Variable: Setting the GH_REPO environment variable allows you to specify a target repository (in OWNER/REPO format) for all gh commands executed in that shell session [1][2]. 2. Command Flag: Passing the --repo or -R flag (e.g., gh label create --repo OWNER/REPO ...) explicitly targets a specific repository, overriding both the current directory's Git remotes and any GH_REPO environment variable [3][1]. Commands like gh label create and gh label edit are used to manage labels [3][4]. Note that gh label create supports a --force flag to update an existing label's description or color if it already exists, preventing validation errors [3][5][6]. If you do not provide a color when creating a label, the CLI will assign a random one [3][5][7]. The GITHUB_REPOSITORY environment variable is often present in CI/CD environments (like GitHub Actions) and holds the value of the repository currently being processed [8][9], but the GitHub CLI primarily relies on its own internal resolution logic—prioritizing the -R flag, then GH_REPO, and finally the local Git remote—to determine its operational context [1][2].

Citations:


Pass the target repository to both mutating gh commands.

This workflow does not check out the repository or set GH_REPO. Therefore, gh label create and gh label edit can fail to resolve the target repository. Their failures are suppressed, so label creation and drift repair can be skipped silently.

Add -R "$GITHUB_REPOSITORY" to both commands.

Pull Request Overview

The PR successfully implements an additive-only, jq-based label classification system that adheres to the restriction against external actions and Python. Codacy reports the PR is up to standards; however, significant technical debt is introduced via the complex regex logic in the classifier script, which lacks unit tests.

Key areas requiring attention before merging include performance inefficiencies in the label synchronization loop (O(N^2) complexity with unnecessary overhead) and a logic contradiction where the 'security' label is marked as both managed and frozen. Additionally, the robustness of the TSV parsing in the sync workflow should be improved to handle special characters in label descriptions.

About this PR

  • The workflows fetch their own logic via 'gh api' and 'base64 -d' to bypass lockfile requirements; while clever, this makes the workflows brittle and harder to debug locally. Additionally, the PR description mentions updating '.github/workflows/actions.lock', but this file is missing from the provided diff.

Test suggestions

  • Verify classify-issue.jq correctly identifies types from conventional commit prefixes (e.g., 'feat:', 'fix:')
  • Verify classify-issue.jq maps keywords to areas (e.g., 'agda' to 'proofs')
  • Verify classify-issue.jq respects the 'max 1' tier limit for types, priorities, and statuses
  • Verify classify-issue.jq does not suggest a type if one already exists in the $have variable (no human override)
  • Verify labels.yml syncs color and description changes for existing labels not in the 'frozen' list
  • Verify triage.yml handles missing classifier payloads gracefully without failing the run
  • Verify classification parity against mock issue titles (e.g., 'feat: add logic', 'fix: cleaning up') to test boundary lookarounds and suffix handling

🔴 HIGH RISK

Suggestion: The JQ-based classifier implements sophisticated regex building with asymmetric boundary checks and inflection handling (e.g., -at, -ment suffixes). As an uncovered complex file, this logic is high-risk. It is recommended to implement a unit test suite using mock issue titles to verify classification accuracy and ensure it respects the 'already have' set to prevent human-override.

🟡 MEDIUM RISK

Suggestion: Optimize the sync loop by pre-loading existing labels into an associative array and moving the sleep timer inside the mutation blocks. Spawning awk and printf inside the loop creates O(N^2) overhead, and the sleep 0.4 currently runs on every iteration regardless of changes, which will significantly delay execution on an estate-wide scale.

⚪ LOW RISK

The security label is currently both managed and frozen. If the intention is to sync its properties (color/description), remove it from the frozen list. Otherwise, remove it from the labels array to clarify that it is handled outside of this sync tool.

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 “the issue has no labels”. The classifier can then suggest a second max-1 label beside a human classification, and line 114 adds it. Exit successfully on read failure. Use [] only after a successful empty response.

Proposed fix
-          HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \

GitHub REST API issues labels conditional update atomic add labels existing labels

💡 Result:

To add labels to a GitHub issue without removing existing labels, you should use the "Add labels to an issue" endpoint rather than the "Update an issue" endpoint [1][2]. The GitHub REST API provides distinct endpoints for different label operations: 1. Add labels to an issue: Use the POST /repos/{owner}/{repo}/issues/{issue_number}/labels endpoint [1][2]. This method specifically appends the provided labels to the issue's existing set of labels [1][3]. 2. Replace (set) labels: Use the PUT /repos/{owner}/{repo}/issues/{issue_number}/labels endpoint [1][2]. This method removes all existing labels on the issue and replaces them entirely with the labels provided in the request body [1][4]. 3. Update an issue (PATCH): Using the PATCH /repos/{owner}/{repo}/issues/{issue_number} endpoint to update the labels field will replace the entire set of labels [5][4]. This behavior is identical to the PUT request for labels [4]. There is no native "atomic conditional add" operation in the GitHub REST API that checks for the existence of a label before adding it. If you need to ensure an issue has a specific label without potentially creating conflicts or triggering unnecessary events, you should first fetch the current labels using GET /repos/{owner}/{repo}/issues/{issue_number}/labels [6][7], verify the desired label is absent, and then call the POST endpoint to add it. Official documentation warns that attempting to use "Update an issue" (PATCH) or "Set labels" (PUT) will clear existing labels [1][4], so the POST endpoint is the only standard way to perform an additive update [1][3].

Citations:


Re-read labels immediately before applying the classifier result.

GitHub’s additive label API has no conditional check. A human can add a max-1 label after HAVE is read, so gh issue edit --add-label can add a conflicting label. Re-read the issue labels immediately before the edit and filter occupied tiers again.

Retry after label synchronisation creates missing labels.

When DEFINED lacks the canonical labels, this path discards valid ADD values and exits. .github/workflows/labels.yml creates missing labels on a scheduled or manual run, but this workflow has no completion trigger or retry. An issue opened during that window remains unlabelled until manual intervention. Add a bounded retry or trigger triage after successful synchronisation.

In @.github/workflows/label-triage.yml around lines 100 - 102, The label-triage
workflow currently exits when ADD contains only labels missing from DEFINED,
leaving issues unlabelled after synchronization. Update the if [[ ${`#apply`[@]}
-eq 0 ]] handling to perform a bounded retry or trigger triage after labels are
successfully synchronized, while preserving the existing no-label behavior and
preventing unbounded workflow recursion.

Serialize overlapping label automation runs.

The synchronization and triage workflows can overlap and act on stale label snapshots. An older synchronization run may restore obsolete metadata, while overlapping triage runs may apply duplicate updates. Add repository-scoped concurrency to synchronization with cancellation, and per-issue serialization to triage without cancellation.

The same overlap risk applies to concurrent triage runs for one issue.
