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, prefixes, keywords and existing labels.
    • Added a standardised label set covering types, areas, priorities, statuses, metadata and scopes.
    • Added workflows to apply and maintain the repository’s canonical labels.
    • Added manual and scheduled options for label synchronisation.
  • Improvements

    • Label triage preserves human-applied labels and fails safely when classification is uncertain.

Walkthrough

Adds a canonical GitHub label taxonomy, a jq issue-title classifier, an additive issue-triage workflow, and a workflow that synchronises mutable labels while preserving frozen labels.

Changes

Label automation

Layer / File(s) Summary
Label taxonomy and classifier rules
.github/labels.json, .github/label-classifier.json
Defines 41 labels, frozen labels, title-prefix rules, bracket-tag rules, keyword signals, tier limits, allowed types, and precedence.
jq issue classification
.github/scripts/classify-issue.jq
Normalises titles, extracts classification signals, enforces tier limits, preserves existing labels, and emits valid new labels.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened or reopened issues, filters suggestions against repository labels, and applies labels additively.
Canonical label synchronisation
.github/workflows/labels.yml
Creates missing labels, updates colour or description drift, skips frozen labels, and reports operation counts.

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

Merge Risk: 🟡 Moderate · up to a1c0b

The new automation can apply labels despite a do-not-automate opt-out, conflict with human label changes, or silently leave canonical labels missing or stale after workflow failures. The PR is not merge-ready until these bounded correctness and synchronization risks are fixed or explicitly accepted.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Honour status:do-not-automate as a global opt-out.

The locked-tier filter at Line 157 prevents only another status label. It does not prevent type, area, meta, or scope labels. For example, an issue with status:do-not-automate and a fix: title still emits bug.

Return no suggestions when $have contains status:do-not-automate. This preserves the taxonomy contract that bots and sweeps must not touch that issue.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Create frozen canonical labels when they are absent.

Line 256 freezes security. The synchroniser skips frozen labels before it tests whether they exist. A repository without security will never create it. The classifier can then suggest security, but triage filters it out because the repository does not define it.

Change the synchroniser to create missing frozen labels, but skip edits to frozen labels that already exist.

Read the canonical payload from the default branch.

This workflow reads .github/labels.json at GITHUB_SHA and applies it to repository labels. A push from another branch or a manual run on another ref can apply unmerged or stale definitions. Restrict push to the default branch and read the payload from github.event.repository.default_branch for every write path.

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

💡 Result:

To use the GitHub CLI (gh) to manage labels in the repository located in your current directory, you do not need to provide any special repository flag; the CLI automatically targets the repository associated with your current directory [1][2]. To create a new label, use the following syntax [3][1]: gh label create --description "" --color <hex_code> Example: gh label create bug --description "Something isn't working" --color E99695 [3][4] Key details for this command include: - Repository Selection: By default, gh commands target the repository in your current directory [1][2]. You only need to use the -R or --repo flag if you wish to target a different repository using the [HOST/]OWNER/REPO format [3][5]. - Color: The color must be a 6-character hexadecimal value (e.g., E99695 or #E99695) [3][6]. If omitted, a random color is assigned [3][4]. - Force: You can use the --force flag to update an existing label's color and description if it already exists, preventing errors [3][6]. For editing existing labels, use the gh label edit command [5][1]: gh label edit --name "<new_name>" --description "<new_description>" --color <new_hex_code> [1][2]

Citations:


Target the repository explicitly for gh label commands.

This step does not check out the repository. Therefore, gh label create and gh label edit cannot infer the repository from the current directory. Their failures are suppressed, so the workflow can report success without synchronising labels. Set GH_REPO: ${{ github.repository }} or pass --repo "$GITHUB_REPOSITORY" to both commands.

Pull Request Overview

The PR successfully implements the required label tooling using jq and shell scripts, adhering to the constraints of avoiding Python and external actions. However, two significant logic bugs and a configuration omission must be addressed.

First, a shell word-splitting bug in the triage workflow will cause failures when applying labels with spaces (e.g., 'good first issue'). Second, the pluralization logic in the classification script is flawed for keywords ending in 'y', leading to missed matches for common pluralized terms.

Additionally, the script .github/scripts/classify-issue.jq is flagged as complex and lacks automated coverage, which likely contributed to the pluralization error. Finally, while the PR description mentions updating .github/workflows/actions.lock, the file is missing from the diff; this is a critical omission for repositories that enforce strict action locking.

About this PR

  • The classification logic is implemented entirely in jq to satisfy the 'no Python' constraint. While effective, this introduces significant complexity. Future maintenance or expansion of these rules will require specialized jq knowledge to avoid regressions.

Test suggestions

  • Classify issue via title prefix (e.g., 'feat: ...' maps to enhancement)
  • Classify issue via bracket tag (e.g., '[p0] ...' maps to priority:p0)
  • Prevent overriding human-applied labels in the same tier (e.g., don't add 'bug' if 'enhancement' exists)
  • Label synchronization skips 'frozen' labels defined in the payload
  • Triage workflow exits silently when no classification is confident
  • Verify correct regex matching for plural forms of keywords ending in 'y' (e.g., 'policies')
  • Verify successful application of labels containing spaces (e.g., 'good first issue')
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify correct regex matching for plural forms of keywords ending in 'y' (e.g., 'policies')
2. Verify successful application of labels containing spaces (e.g., 'good first issue')

🔴 HIGH RISK

The command substitution used to generate flags will break when label names contain spaces because the shell performs word splitting on the result. Use a Bash array to safely collect and pass these dynamic arguments.

Try running the following prompt in your coding agent:

In the Label Triage workflow, fix the shell word splitting bug in the gh issue edit command. Instead of using command substitution to generate --add-label flags, initialize a Bash array to build the command and execute it using the "${cmd[@]}" pattern to preserve spaces in label names.

🟡 MEDIUM RISK

The changes to '.github/workflows/actions.lock' mentioned in the PR description are missing. In repositories enforcing action locking, these workflows will fail to start without a corresponding entry in the lockfile.

🟡 MEDIUM RISK

The pluralization logic for keywords ending in 'y' is incorrect. It appends 'ies' to the full word (e.g., 'theoryies') instead of replacing the 'y'. This file is identified as complex and currently lacks test coverage, which increases the risk of such logic errors remaining undetected.

Try running the following prompt in your IDE agent:

Modify the kwrx function in .github/scripts/classify-issue.jq so that if a keyword ends in 'y', the generated regex matches both the singular form (e.g., 'theory') and the correct 'ies' plural form (e.g., 'theories') by optionally replacing the trailing 'y'.

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.

661-665: Retain status:do-not-automate as a global opt-out.

Lines [661]-[665] declare this label in the status tier, but the supplied classify function in .github/scripts/classify-issue.jq only locks the status tier. It can still emit type, area, meta, or scope labels for an issue that already has status:do-not-automate. Return no suggestions when $have contains this label.

Do not flag label-registry drift.

All 39 labels in .github/labels.json are present in the classifier registry. The 17 frozen labels match exactly between both top-level frozen arrays. The proposed check reports false positives because it compares frozen labels with .labels[], although frozen labels are stored separately.

.github/workflows/labels.yml (3)

20-26: Read label definitions from the default branch.

push has no branch filter, and the fetch uses $GITHUB_SHA. A push or manual run on a non-default ref can apply unmerged or stale .github/labels.json content to the repository. Restrict synchronisation to the default branch and fetch ${{ github.event.repository.default_branch }} for every write path.

Also applies to: 51-53


20-26: Serialise label synchronisation runs.

push, workflow_dispatch, and schedule can overlap. An older run can write stale colour or description values after a newer run. Add workflow-level concurrency for repository label synchronisation.

47-55: Propagate fetch and parse failures.

|| true at Line [52] converts API, decoding, and malformed-payload failures into the successful no-file path. The jq process substitutions at Lines [55] and [94] do not propagate their exit status to the step. Handle only an expected 404 as a no-op and fail on other fetch and parse errors.

Also applies to: 94-94

# Labels already present; a human's work is never overridden. Read
# HERE rather than earlier: every API call between this read and the
# edit below widens a window in which someone could add a type label
# and get a second one back from us. Only the local jq call is inside it.

Revalidate labels before applying suggestions.

The HAVE snapshot is read before classification and the final write. If a human adds a max-1 label after that read, the stale ADD array can add a conflicting label at Line [114].

Re-read the labels immediately before the edit and re-run classification and filtering against the new snapshot. Serialise triage runs for the same issue to reduce automation races.

Fail closed when the label read fails.

|| HAVE='[]' treats an API error as a successful empty-label response. If the read fails but the later gh issue edit succeeds, the classifier can add a type label beside a human-selected type.

Exit without applying labels when gh issue view fails. Use [] only after a successful response with no labels.

Proposed fix
-          HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \
-                   --json labels --jq '[.labels[].name]' 2>/dev/null) || HAVE='[]'
+          if ! HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \
+                   --json labels --jq '[.labels[].name]' 2>/dev/null); then
+            echo "could not read existing labels - leaving for a human"
+            exit 0
+          fi

Do not report an incomplete synchronisation as successful.

When one gh label create or gh label edit operation fails and another succeeds, the condition at Lines [101]-[104] is false. The job then exits 0 with failed > 0, leaving missing or stale canonical labels without a failed check to trigger action. Retry failed mutations and exit non-zero if any failure remains.

Minimal failure-status fix
-          if [ "$failed" -gt 0 ] && [ "$((created + updated))" -eq 0 ]; then
+          if [ "$failed" -gt 0 ]; then
