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 or reopened issues based on their titles and existing labels.
    • Added scheduled and manually triggered synchronisation for standard repository labels.
    • Added support for creating missing labels and updating non-protected label details.
  • Improvements

    • Label management now reports labels that were created, updated, or skipped.
    • Classification avoids overwriting existing labels and remains silent when confidence is low.

Walkthrough

Added a versioned label taxonomy, a jq issue classifier, and two GitHub Actions workflows. One workflow synchronises repository labels. The other classifies opened, reopened, or manually selected issues and applies valid labels without removing existing labels.

Changes

Label automation

Layer / File(s) Summary
Label taxonomy and classification rules
.github/labels.json, .github/label-classifier.json
Defines categorised labels, frozen labels, title prefixes, bracket tags, keyword signals, supported types, tier limits, and precedence.
Issue title classifier
.github/scripts/classify-issue.jq
Parses title tags and prefixes, matches keywords, selects one type, enforces tier limits, protects existing labels, and emits canonical suggestions.
Repository label synchronisation
.github/workflows/labels.yml
Creates missing labels, preserves frozen labels, updates non-frozen metadata, and reports operation counts.
Automated issue triage
.github/workflows/label-triage.yml
Fetches classification inputs, runs the jq classifier, filters suggestions to defined labels, and applies labels additively.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to ceeda

The new automation can currently apply repository-wide label changes from unmerged branches, misclassify issues when existing labels cannot be read, silently skip synchronization failures, and leave issues untriaged after labels are created. Merge should wait for these bounded correctness and integrity risks to be addressed or explicitly accepted.

Pull Request Overview

The PR implements a custom label triage system using canonical taxonomies and JQ-based logic. While the implementation meets the repository's strict environmental constraints, it is currently incomplete as it references scripts and test suites in code headers that were not included in the changeset. This gap, combined with the high complexity and zero test coverage for the JQ classifier, represents a significant maintainability and regression risk.

A medium-severity issue was identified in the label synchronization workflow regarding the handling of multi-line descriptions which could lead to corrupted label states. Several performance optimizations for the CI workflows were also identified to reduce execution time and API overhead. These items should be addressed to ensure the reliability of the automated triage system.

About this PR

  • The PR code headers reference several supporting files that are not present in the current changeset: scripts/gen-classifier-json.py, scripts/gen-labels-json.py, and tests/test-classifier-parity.py. These are essential for the maintenance and verification of the label taxonomy and should be included.
  • The reliance on gh api to fetch configuration via $GITHUB_SHA prevents easy local execution and debugging of the classification logic. Consider a fallback mechanism for local testing environments.

Test suggestions

  • Missing recommended test scenario: Verify classifier matches conventional commit prefixes (e.g., 'feat:') to the 'enhancement' type.
  • Missing recommended test scenario: Verify classifier matches bracket tags (e.g., '[gov]') to the 'governance' area.
  • Missing recommended test scenario: Verify keyword matches (e.g., 'guix' in the title) assign the 'packaging' area.
  • Missing recommended test scenario: Verify classifier respects human input by refusing to add a 'type' label if the issue already has one.
  • Missing recommended test scenario: Verify classifier returns an empty list when no prefix, bracket, or type rule is triggered (silent when unsure).
  • Missing recommended test scenario: Verify label sync workflow creates missing labels even if they are in the 'frozen' list.
  • Missing recommended test scenario: Verify label sync workflow skips updates to color/description for existing 'frozen' labels.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing recommended test scenario: Verify classifier matches conventional commit prefixes (e.g., 'feat:') to the 'enhancement' type.
2. Missing recommended test scenario: Verify classifier matches bracket tags (e.g., '[gov]') to the 'governance' area.
3. Missing recommended test scenario: Verify keyword matches (e.g., 'guix' in the title) assign the 'packaging' area.
4. Missing recommended test scenario: Verify classifier respects human input by refusing to add a 'type' label if the issue already has one.
5. Missing recommended test scenario: Verify classifier returns an empty list when no prefix, bracket, or type rule is triggered (silent when unsure).
6. Missing recommended test scenario: Verify label sync workflow creates missing labels even if they are in the 'frozen' list.
7. Missing recommended test scenario: Verify label sync workflow skips updates to color/description for existing 'frozen' labels.

🟡 MEDIUM RISK

The @tsv format used in the while read loop is vulnerable to literal newlines in label descriptions. If a description contains a newline, jq outputs it literally, causing the shell to incorrectly parse subsequent lines as new records, leading to corrupted labels.

# A rule must actually have FIRED: keyword-area hits alone are not enough.
| if ($matched | not) then []
# a type is mandatory
elif ((($out + $have) | any(. as $x | $types | index($x))) | not) then []

🟡 MEDIUM RISK

Suggestion: This file is flagged as highly complex and currently lacks automated test coverage. The current logic strictly requires a 'type' label to be identified before applying any others. Consider allowing 'area' or 'status' labels to be applied independently if they meet a high confidence threshold, while maintaining existing 'enforce' tier constraints.

Suggestion: The sleep 0.4 safeguard should only trigger when a write operation (gh label create or gh label edit) is actually performed. Moving the sleep inside the conditional update blocks will optimize performance for the frequent 'no-op' runs.

⚪ LOW RISK

Suggestion: Performing an awk lookup inside the loop is inefficient ($O(N^2)$). Refactor the workflow to use a single jq command to compare the local payload with existing labels and generate the necessary gh commands in bulk.

Add a recovery path after label synchronisation.

If this repository does not yet define a suggested label, this path exits successfully and discards the classification. A later scheduled or manual label synchronisation creates that label, but it does not re-trigger this issues workflow. The issue then remains unlabelled until a user manually dispatches or reopens it.

Run a bounded reclassification backfill after label synchronisation, or ensure canonical labels exist before this workflow can process issues.

GitHub CLI gh label create gh label edit --repo GH_REPO environment variable repository resolution documentation

💡 Result:

The GitHub CLI (gh) resolves the target repository for commands like gh label create and gh label edit using a specific order of precedence [1][2]. Repository Resolution Precedence: 1. --repo flag: When provided, the --repo (or -R) flag explicitly overrides all other methods [3][4][2]. 2. GH_REPO environment variable: If the flag is not used, gh checks the GH_REPO environment variable [2][5]. This variable must be in the [HOST/]OWNER/REPO format [2][6]. 3. Local Git repository: If neither the flag nor the environment variable is set, gh attempts to resolve the repository by inspecting the remotes configured in the current local Git repository [2][5]. Important Notes: - The GITHUB_REPOSITORY environment variable (commonly used in GitHub Actions) is not automatically read by the GitHub CLI [1]. To use it, you must explicitly map it to the GH_REPO environment variable in your workflow configuration [1][7]: env: GH_REPO: ${{ github.repository }} - The GH_REPO variable is highly useful in environments where a local Git repository is not present or when you need to perform operations on a repository other than the current one [5][6]. Top Results: [3][1][2]

Set the repository for both label mutations.

This workflow does not check out the repository and sets GITHUB_REPOSITORY, not GH_REPO. Therefore, gh label create and gh label edit may not resolve a repository. Their failures are suppressed, so the job can report success without synchronising labels. Pass -R "$GITHUB_REPOSITORY" to both commands.

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.

Do not treat a failed label read as an empty label set.

Line 82 assigns HAVE='[]' when gh issue view fails. The classifier uses have to protect max-1 taxonomy tiers. The workflow can therefore add a canonical label beside a human classification that the failed read did not return.

If the label read fails, exit successfully without applying labels. Only use [] when the command succeeds and returns an empty array.

Proposed safe fallback
-          HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \
-                   --json labels --jq '[.labels[].name]' 2>/dev/null) || HAVE='[]'

Restrict automatic synchronisation to the canonical branch.

The push trigger matches every branch. A push to an in-repository PR branch can fetch its unmerged .github/labels.json and immediately create or edit global repository labels. Restrict automatic runs to the protected default branch. For manual runs, use or validate the default-branch configuration before mutation.

Serialise label mutations and triage runs.

Scheduled, dispatched, push-triggered, issue-triggered, and manual runs can overlap. Each run may read a stale label snapshot before writing, allowing delayed metadata to overwrite newer state or causing concurrent edits to race. Add repository-scoped workflow concurrency, keyed per issue for triage runs and repository-wide for label synchronisation.

Fail when the canonical payload is invalid or cannot be fetched.

|| true hides fetch and decode failures. Also, jq failures in the later process substitutions do not fail this shell. A malformed .github/labels.json therefore produces created=0 updated=0 and exits successfully without synchronising labels. Validate the downloaded JSON shape before reading .frozen or .labels, and fail on retrieval, decode, or validation errors.

workflow payload retrieval and parsing around PAYLOAD and the FROZEN mapfile so
fetch, base64 decode, and jq failures propagate instead of being suppressed.
Enable reliable failure handling for process substitutions, then validate that
the downloaded payload is valid JSON with the expected frozen and labels
structure before reading either field; retain the no-file early exit only when
the payload is genuinely absent.
