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 scheduled and on-demand synchronisation of the repository’s standard labels.
    • Preserves existing labels while applying confident classifications only.
  • Improvements

    • Standardised label categories, priorities, scopes and descriptions.
    • Added safeguards to prevent unwanted label deletion or modification.

Walkthrough

The change adds generated GitHub label definitions and classifier rules. A jq script classifies issue titles. Two GitHub Actions workflows apply issue labels and synchronise the repository label set.

Changes

GitHub label automation

Layer / File(s) Summary
Label taxonomy and generated data
.github/label-classifier.json, .github/labels.json
Defines title prefixes, bracket tags, keyword signals, label tiers, precedence, valid types, frozen labels, and 39 canonical labels.
jq issue classifier
.github/scripts/classify-issue.jq
Normalises titles, resolves rules and signals, enforces tier limits, preserves existing labels, and emits canonical labels.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened, reopened, or manually selected issues and adds matching repository labels without removing existing labels.
Label synchronisation workflow
.github/workflows/labels.yml
Creates missing labels, updates non-frozen metadata, skips frozen labels, and reports operation counts.

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

Merge Risk: 🟡 Moderate · up to 5e79f

This PR adds automated label creation and issue triage, but the current implementation can silently fail to synchronize labels, miss labels created concurrently, apply classifications based on stale state, and modify issues that opted out of automation. Merge should wait for these bounded correctness and policy risks to be fixed or explicitly accepted.

Pull Request Overview

The PR successfully implements a canonical label taxonomy and an automated triage system using a jq-based classifier. While the PR is overall 'up to standards' according to Codacy, there is a significant discrepancy: the PR description mentions updating .github/workflows/actions.lock, but this file is missing from the diff. This omission will cause workflow failures in environments where lockfile enforcement is enabled.

Additionally, the triage logic resides in a high-complexity JQ script (.github/scripts/classify-issue.jq) which currently lacks in-repo tests, posing a maintainability risk. There is also a potential technical debt regarding the GitHub Contents API 1MB limit for file retrieval which may affect future scalability.

About this PR

  • Discrepancy: The PR description explicitly mentions updating .github/workflows/actions.lock to prevent startup failures, but this file is missing from the diff. This must be corrected to ensure the new workflows can execute.

Test suggestions

  • Verify prefix-based classification (e.g., 'feat: ...' maps to 'enhancement')
  • Verify bracket-tag classification (e.g., '[p0] ...' maps to 'priority:p0')
  • Verify keyword-based area mapping (e.g., 'workflow' in title adds 'cicd' label)
  • Confirm existing human labels prevent the classifier from adding a second label in the same tier (e.g., existing 'bug' prevents adding 'enhancement')
  • Ensure the triage workflow exits gracefully when labels.json or the jq script are missing
  • Automate unit tests for .github/scripts/classify-issue.jq to address complexity risk
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify prefix-based classification (e.g., 'feat: ...' maps to 'enhancement')
2. Verify bracket-tag classification (e.g., '[p0] ...' maps to 'priority:p0')
3. Verify keyword-based area mapping (e.g., 'workflow' in title adds 'cicd' label)
4. Confirm existing human labels prevent the classifier from adding a second label in the same tier (e.g., existing 'bug' prevents adding 'enhancement')
5. Ensure the triage workflow exits gracefully when labels.json or the jq script are missing
6. Automate unit tests for .github/scripts/classify-issue.jq to address complexity risk
Low confidence findings
  • The triage workflow depends on fetching files via the GitHub API using GITHUB_SHA. If the workflow runs on an issue event before the PR is merged, it may fetch the version from the default branch instead of the PR version, potentially leading to inconsistent triage results during the testing phase.

🟡 MEDIUM RISK

This script implements complex classification logic, including custom regex boundary handling and precedence sorting. Its high logic density and lack of in-repo tests make it a risk for maintainability. Ensure that any changes are verified against the external parity tests mentioned in the file header.

Try running the following prompt in your IDE agent:

Create a comprehensive set of test cases for the classify function in this JQ script, covering: 1. Prefix matches (fix:), 2. Bracket tags ([estate]), 3. Keyword-based area detection, 4. Type precedence (bug vs enhancement), and 5. Handling of existing labels ($have).

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Stop mutation when automation is disabled.

If HAVE contains status:do-not-automate, the classifier only locks the status tier. It can still emit labels such as bug for a fix: title. Lines 105-108 then modify an issue that the canonical label definition excludes from bots and sweeps.

Exit successfully before classification when this label is present.

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

💡 Result:

The GitHub CLI (gh) allows you to manage repository labels using the gh label create and gh label edit commands [1][2]. Repository Selection By default, the GitHub CLI infers the target repository from the current working directory's Git remotes [3][4]. You can override this behavior and specify a different repository using the following methods: 1. --repo Flag: Use the --repo (or -R) flag followed by the [HOST/]OWNER/REPO format to explicitly target a specific repository [1][5][6]. This flag overrides any repository detected from the current directory [3]. 2. GH_REPO Environment Variable: You can set the GH_REPO environment variable to a repository name in the [HOST/]OWNER/REPO format [7][8]. The GitHub CLI will use this value if the --repo flag is not provided [7]. Command Manuals gh label create Creates a new label on GitHub [9][5]. Synopsis: gh label create [flags] Key Flags: --color : Sets the 6-character hex color code [9][10]. --description : Adds a description to the label [9][11]. --force: Updates the label if it already exists [9][5]. gh label edit Updates an existing label [6][12]. Synopsis: gh label edit [flags] Key Flags: --name : Renames the label [6][12]. --color : Changes the label's color [6][12]. --description : Changes the label's description [6][12]. For example, to update the color of a "bug" label in a specific repository, you can run: gh label edit bug --color FF0000 --repo owner/repository

Set the repository for both label mutations.

This workflow does not check out the repository or set GH_REPO. Without -R or GH_REPO, gh resolves the repository from local Git remotes, so both mutations can fail before changing GitHub. The suppressed failures allow the workflow to succeed with label drift. Add -R "$GITHUB_REPOSITORY" to both commands.

Re-check labels before applying the classification.

The workflow reads HAVE on Lines 82-83, classifies on Lines 87-88, and writes on Lines 112-114. A human or another workflow can add a max-1 label during this interval. The classifier in .github/scripts/classify-issue.jq Lines 119-162 then uses stale state and can add a conflicting label beside the human label.

Add per-issue workflow concurrency and re-read and re-run the classifier immediately before the write. A strict guarantee also needs a server-side conditional operation; this read-then-add sequence cannot provide it.

Also applies to: 112-114

Retry when labels are not yet defined.

.github/workflows/label-triage.yml reads DEFINED once and filters ADD against it. If .github/workflows/labels.yml creates labels during this window, missing labels are discarded and only the remaining labels are applied. The workflows have no ordering or completion dependency. Re-fetch and retry missing labels, or hand off triage after synchronisation.

application flow around DEFINED and the apply array to handle labels created
after the initial fetch: re-fetch the defined labels and retry unresolved ADD
entries before discarding them, or defer triage until label synchronization
completes. Ensure labels newly created by the synchronization workflow are
included in the eventual application.

Serialise repository label mutations.

GitHub Actions permits concurrent workflow runs by default. Two runs can read the same missing label at Line 58, then both create it at Line 75. One run succeeds, while the other records a failure and can exit unsuccessfully at Lines 101-103. Add a repository-wide concurrency group. Do not cancel an active synchronisation. (docs.github.com)

Fail when the canonical payload cannot be fetched.

If gh api or base64 -d fails at Line 52, || true hides the failure. Line 53 then exits successfully without synchronising any labels. Propagate the fetch or decode failure instead of treating it as an absent optional file.

Proposed fix

-            --jq '.content' 2>/dev/null | base64 -d > "$PAYLOAD" || true
