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 classification and labelling for newly opened or reopened issues.
    • Added a standardised label catalogue covering type, area, priority, status, metadata and scope.
    • Added scheduled and manual synchronisation to create or update repository labels.
    • Classification remains additive-only and avoids applying labels when confidence is insufficient.
    • Added support for manually triggering label triage and label synchronisation.

Walkthrough

The change adds a canonical GitHub label taxonomy, a jq issue-title classifier, and workflows that synchronise labels and apply classification results to new or reopened issues.

Changes

Label automation

Layer / File(s) Summary
Label taxonomy and rules
.github/label-classifier.json, .github/labels.json
Defines title, bracket-tag, keyword, signal, tier, precedence, type, and frozen-label data. Defines 35 canonical labels with colours, descriptions, and tiers.
Canonical label synchronisation
.github/workflows/labels.yml
Fetches the canonical label configuration, creates missing labels, updates colour and description drift, skips present frozen labels, and reports mutation results.
Issue title classification
.github/scripts/classify-issue.jq, .github/label-classifier.json
Parses title prefixes and bracket tags, matches bounded keywords and signals, enforces tier maxima, and returns valid labels not already present.
Issue triage workflow
.github/workflows/label-triage.yml, .github/scripts/classify-issue.jq, .github/label-classifier.json
Fetches issue data and classifier inputs, filters suggestions against repository labels, and adds labels without failing on missing data or API errors.

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

Merge Risk: 🟡 Moderate · up to 0ab38

The new automation can misclassify issues or alter protected labels when label data is invalid, unavailable, differently cased, or processed concurrently. The change is not merge-ready until these bounded correctness and synchronization risks are addressed or explicitly accepted.

Prevent stale synchronisation runs from writing after newer runs.

Two push runs can use different GITHUB_SHA values. The older run can finish after the newer run and restore stale label colours or descriptions. Add a workflow-level concurrency group with cancel-in-progress: true.

Pull Request Overview

This PR establishes a standardized label taxonomy and automated triage system. While the implementation adheres to environment constraints (using 'jq' and 'gh' CLI), there is a significant validation gap. All core classification requirements—such as priority-based precedence, human-override protection, and keyword matching—lack automated test coverage in the current diff.

Furthermore, the label synchronization workflow contains fragile shell processing that could fail when encountering labels with special characters (tabs/newlines). Although Codacy reports the PR as up to standards, the complexity of the classification script without test coverage constitutes a medium-level risk for future regressions.

About this PR

  • The PR introduces complex classification logic in jq but lacks an accompanying test suite or test data. Given the nuanced rules for tier limits and human-override protection, automated verification is essential to prevent misclassification.

Test suggestions

  • Classification of issues via Conventional Commit title prefixes (e.g., 'feat:', 'fix:')
  • Classification of issues via bracketed tags (e.g., '[gov]', '[p1]')
  • Keyword-based area detection (e.g., 'workflow' mapped to 'cicd')
  • Keyword-based type detection with priority-based precedence (e.g., 'crash' over 'cleanup')
  • Prevention of label assignment to tiers (type, priority, etc.) already containing a human-assigned label
  • Enforcement of tier limits (e.g., strictly ensuring maximum of one 'type' label)
  • Additive-only label synchronization to ensure existing repo-specific labels are not deleted
  • Protection of 'frozen' labels from automated color or description updates
  • Automatable unit tests for .github/scripts/classify-issue.jq logic
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classification of issues via Conventional Commit title prefixes (e.g., 'feat:', 'fix:')
2. Classification of issues via bracketed tags (e.g., '[gov]', '[p1]')
3. Keyword-based area detection (e.g., 'workflow' mapped to 'cicd')
4. Keyword-based type detection with priority-based precedence (e.g., 'crash' over 'cleanup')
5. Prevention of label assignment to tiers (type, priority, etc.) already containing a human-assigned label
6. Enforcement of tier limits (e.g., strictly ensuring maximum of one 'type' label)
7. Additive-only label synchronization to ensure existing repo-specific labels are not deleted
8. Protection of 'frozen' labels from automated color or description updates
9. Automatable unit tests for `.github/scripts/classify-issue.jq` logic
Low confidence findings
  • The label configuration and classifier JSON files are marked as generated from an external private repository. This opaque generation process hinders manual audits and makes it difficult for contributors to propose logic adjustments directly.

🟡 MEDIUM RISK

Suggestion: This jq script contains critical logic for inflection-tolerant matching and label tier enforcement. The kwrx function's handling of word boundaries and the stem-based suffix logic are particularly prone to edge cases. To ensure maintainability, consider adding a shell-based test suite that runs jq against sample issue titles and asserts expected label outputs.

🟡 MEDIUM RISK

Suggestion: The loop-based 'awk' lookup is inefficient and fragile if label names or descriptions contain tabs or newlines. Consider loading the existing labels into a Bash associative array for better reliability and performance.

Try running the following prompt in your coding agent:

In .github/workflows/labels.yml, replace the 'existing' label lookup loop (lines 51-72) with a pattern that fetches existing labels into a Bash associative array first, then iterates the payload labels to check for creation or updates.

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.

GitHub CLI official documentation gh issue edit --add-label adds labels GitHub Actions concurrency default concurrent runs

💡 Result:

The GitHub CLI command gh issue edit --add-label is used to append one or more labels to a specified issue or set of issues [1][2]. You can provide multiple labels as a comma-separated string [1][2]. Regarding GitHub Actions concurrency, the default behavior allows multiple workflows and jobs to run concurrently [3][4]. When you use the concurrency keyword to define a concurrency group, GitHub Actions ensures that only one job or workflow in that group runs at a time [3][5]. If a new job or workflow is triggered while another is already in progress within the same group, the new one will enter a pending state [3][6]. By default, if another run is already pending, that pending run will be canceled to allow the latest one to proceed [3][6]. You can modify this behavior by setting the group's queueing strategy (e.g., using queue: max) to allow up to 100 pending runs instead of canceling them [3][6].

Citations:


Serialise classification runs per issue and revalidate before editing.

The classifier enforces max-one tiers only against the labels in its snapshot. gh issue edit --add-label then applies the result additively. A label added after the snapshot can therefore leave the issue with conflicting type, priority, status, meta, or scope labels. Add a per-repository/per-issue concurrency group with cancel-in-progress: false, then re-read the labels and recompute immediately before editing.

site:docs.github.com REST API issue labels label names case insensitive GitHub

💡 Result:

In the context of the GitHub REST API and repository management, label names are considered case-sensitive [1][2]. While repository names and owner names are explicitly documented as not case-sensitive [1][3], label names themselves behave as unique, case-sensitive identifiers [1][2]. When using the API to create, update, or reference labels, you must provide the exact string matching the case of the label [4]. Attempting to reference a label with a different case (e.g., using "Bug" when the label is defined as "bug") will typically result in an error or the inability to locate the specified label [1][4].

classify-issue.jq matches HAVE against $RULES.tier_of with exact string comparison. If the repository defines Enhancement but the taxonomy key is enhancement, the classifier ignores the existing type and can add bug for a fix: title. The case-sensitive DEFINED comparison can also discard a canonical result.

Enforce the taxonomy’s exact-casing invariant in .github/workflows/labels.yml, or map each result to its exact repository label name before building apply.

Do not classify or edit when reading existing labels fails.

When gh issue view ... --json labels fails, HAVE='[]' reaches the classifier. A fix: title can then produce bug even when the issue already has enhancement, and execution reaches gh issue edit. Exit 0 before classification and add a regression test that confirms gh issue edit is not called.

Validate the payload shape before reading FROZEN.

If .frozen is missing or invalid, jq fails inside the process substitution but mapfile still succeeds with an empty array. The workflow then treats every existing label as non-frozen and can change protected label colours or descriptions. Validate both required arrays and stop before any mutation.

Proposed fix
+          if ! jq -e '(.frozen | type == "array") and (.labels | type == "array")' \
+            "$PAYLOAD" >/dev/null; then
+            echo "invalid canonical label payload"
+            exit 1
+          fi
+
           mapfile -t FROZEN < <(jq -r '.frozen[]' "$PAYLOAD")
