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 titles, keywords, prefixes and status indicators.
    • Added synchronisation for standard repository labels, including protection for frozen labels.
    • Added support for processing newly opened, reopened or manually selected issues.
  • Chores

    • Added centrally managed label definitions and classification rules.
    • Added scheduled and change-triggered label maintenance workflows.

Walkthrough

Adds canonical label definitions, a jq issue classifier, an issue-triage workflow, and a label-synchronisation workflow. The automation uses repository-hosted files, preserves existing and frozen labels, filters unknown labels, and handles unavailable data without failing.

Changes

Issue Label Automation

Layer / File(s) Summary
Label contracts
.github/label-classifier.json, .github/labels.json
Defines label mappings, keyword rules, signals, tiers, precedence, canonical metadata, and frozen labels.
Issue title classifier
.github/scripts/classify-issue.jq
Classifies titles from explicit tags, prefixes, keywords, and signals. It preserves existing labels, enforces tier limits, and emits only confident canonical suggestions.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened, reopened, or manually selected issues. It filters suggestions against repository labels and applies them with safe argument arrays.
Label synchronisation
.github/workflows/labels.yml
Creates and updates canonical labels on configured triggers. It preserves frozen labels and reports mutation failures.

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

Merge Risk: 🟡 Moderate · up to 1671f

The PR adds automated label synchronization and issue triage, but the synchronization can act on malformed runtime data without failing, potentially removing frozen-label protection or falsely reporting success. Overlapping runs can also produce spurious failures, and non-frozen label updates may not converge. Merge should wait for these handling fixes.

A rabbit sorts labels in a neat little row
Prefixes and keywords tell workflows where to go
Frozen marks stay safe, untouched in their place
jq finds clear signals with careful grace
GitHub receives labels, one safe hop at a time

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.

🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Add a concurrency group.

Three triggers can overlap: workflow_dispatch, a push that touches .github/labels.json, and the monthly cron. Two concurrent runs read the same label set and then both try to create the same missing label. One create fails, failed increases, and the run reports a failure that is not real drift.

     - cron: "23 4 1 * *"   # monthly drift repair

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Validate the fetched payload before you act on it. The step reads frozen and labels from a file fetched at runtime and never checks the jq exit status. A payload that lacks either key does not stop the run: it removes frozen protection or turns the sync into the silent no-op described at Lines 42-44.

  • .github/workflows/labels.yml#L55-L59: use .frozen // [] | .[] with jq -e, fail when the list is malformed, and check the exit status of the gh api .../labels call before you treat existing as complete.
  • .github/workflows/labels.yml#L94-L105: count (.labels // []) | length and exit non-zero when the payload defines no labels, so a missing labels array cannot report success.

gh label create --force flag GitHub CLI documentation

💡 Result:

The --force flag for the gh label create command in the GitHub CLI is used to update an existing label instead of failing if the label already exists [1][2]. When you use --force, the command will update the label's color and description if a label with the specified name is already present in the repository [1][3]. Without this flag, the command will typically return an error (HTTP 422: Validation Failed) if you attempt to create a label that already exists [4]. This functionality makes the command idempotent, which is particularly useful in automation scripts or CI/CD pipelines where you want to ensure labels exist with specific configurations without triggering errors upon re-runs [4]. Usage example: gh label create --color --description --force [1][4]

Citations:


Use gh label create --force for non-frozen labels.

gh label create --force updates an existing label's colour and description instead of failing. For non-frozen labels, this can replace the create/compare/edit branches and remove reliance on the existing snapshot. Keep plain create for frozen labels because --force can overwrite them. Update the created and updated counters in the report.
