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, tags and keywords.
    • Added synchronisation for creating and updating repository labels.
    • Added safeguards to preserve existing and protected labels.
    • Added manual and scheduled options for maintaining labels.
    • Added support for processing newly opened, reopened, or manually selected issues.

Walkthrough

Adds generated label taxonomy files, a jq issue classifier, an additive issue-triage workflow, and a workflow that synchronises repository labels while preserving frozen labels.

Changes

Issue label automation

Layer / File(s) Summary
Label taxonomy and registry
.github/label-classifier.json, .github/labels.json
Adds generated classification rules, label definitions, tier limits, precedence values, and frozen-label metadata.
Issue classification logic
.github/scripts/classify-issue.jq
Normalises issue titles, matches prefix, bracket, keyword, status, meta, and scope signals, enforces tier limits, and returns canonical labels not already present.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies newly opened or reopened issues, filters suggestions to repository labels, and applies them without removing existing labels.
Label synchronisation workflow
.github/workflows/labels.yml
Creates missing labels and updates mutable colours or descriptions on manual, push, and monthly scheduled runs. Frozen labels are skipped.

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

Merge Risk: 🟡 Moderate · up to 8288a

The new workflows can apply label changes from non-default branch content, silently complete without synchronizing labels, overwrite newer label metadata during concurrent runs, and modify issues that opted out of automation. These bounded repository-control and correctness risks should be fixed or explicitly accepted before merge.

A rabbit sorts labels in rows,
jq checks each title as it goes.
Frozen marks stay where they lie,
New labels hop into the sky,
And tidy workflows watch the flows.

Respect status:do-not-automate before classification.

The registry defines this label as a control that prevents bot and sweep changes. A reopened issue or manual run with this label still reaches gh issue edit and receives automatic labels. Exit after reading HAVE when it contains status:do-not-automate.

Proposed fix
           HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \

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

💡 Result:

The GitHub CLI command to create a label is gh label create <name> [flags] [1][2]. By default, the gh label create command operates on the repository located in the current directory [3]. If you are not in the directory of the desired repository, or if you wish to target a different repository, you can use the -R or --repo flag [1][4]. The syntax for specifying a repository is: gh label create <name> --repo <[HOST/]OWNER/REPO> [1][5] For example: gh label create "bug" --repo "owner/my-repository" Key options available for the command include: - -c, --color: Sets the label color using a 6-character hex value [1][2]. - -d, --description: Adds a description to the label [1][2]. - -f, --force: Updates the label's color and description if the label name already exists in the repository [1][2][6]. If you do not specify a color, the CLI will assign a random one [1][5]. [1][4][2][3][5]

GitHub Actions default bash shell -e pipefail documentation

💡 Result:

In GitHub Actions, the pipefail option is automatically enabled when you explicitly specify shell: bash for a step or job [1][2]. When you use shell: bash, GitHub Actions executes your script using the command: bash --noprofile --norc -eo pipefail {0} [1][3]. The inclusion of -o pipefail ensures that if any command in a pipeline fails (returns a non-zero exit status), the entire pipeline returns a non-zero exit status, causing the GitHub Actions step to fail [2][4]. Important distinctions to note: 1. Explicit vs. Unspecified Shell: If you do not specify a shell (i.e., you omit the shell keyword), the default behavior on Linux and macOS is bash -e {0} [1][5]. This default behavior includes set -e (errexit) but does not include pipefail [6][7]. Therefore, if you require pipefail behavior, you must explicitly set shell: bash [8][9]. 2. Customization: You can override these defaults by providing a custom string to the shell keyword [1][2]. For example, if you need to use pipefail with a different configuration or ensure strict error handling, you can define your own shell command, such as shell: bash -Eueo pipefail -x {0} [3][10]. In summary, to guarantee that pipe failures cause your GitHub Actions step to fail, always explicitly declare shell: bash in your workflow YAML [9][11].

Pass the target repository to each label mutation and make mutation failures fatal.

This job does not check out the repository. gh label create and gh label edit can therefore fail without --repo "$GITHUB_REPOSITORY". The runner enables errexit, but a failed command before && is exempt. The redirected error output then hides the failure. Run each mutation as a standalone command before incrementing its counter.

Pull Request Overview

The implementation successfully adheres to the technical constraints of avoiding Python and external GitHub Actions by utilizing a custom jq-based engine. While Codacy reports the codebase is up to standards, two critical issues remain: a logic flaw in how labels are applied via shell commands which will fail for labels containing spaces (e.g., 'good first issue'), and a lack of unit tests for the 160-line classification logic. Furthermore, the PR description mentions updating actions.lock to prevent startup failures, but these changes are absent from the file diff.

About this PR

  • The classification engine in jq is quite complex (~160 lines). Please provide unit tests or automated verification scenarios to ensure the rules correctly handle various issue payloads and edge cases.

Test suggestions

  • Classification of issue via conventional commit prefix (e.g., 'fix:' mapping to 'bug')
  • Classification of issue via bracket tags (e.g., '[estate]' mapping to 'scope:estate')
  • Keyword-based area labeling (e.g., 'workflow' mapping to 'cicd')
  • Enforcement of tier limits (e.g., ensuring only one 'type' label is suggested)
  • Preservation of existing human-applied labels (non-override logic)
  • Inflection-tolerant keyword matching (e.g., 'test' matching 'tests' or 'testing')
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classification of issue via conventional commit prefix (e.g., 'fix:' mapping to 'bug')
2. Classification of issue via bracket tags (e.g., '[estate]' mapping to 'scope:estate')
3. Keyword-based area labeling (e.g., 'workflow' mapping to 'cicd')
4. Enforcement of tier limits (e.g., ensuring only one 'type' label is suggested)
5. Preservation of existing human-applied labels (non-override logic)
6. Inflection-tolerant keyword matching (e.g., 'test' matching 'tests' or 'testing')
Low confidence findings
  • The PR description mentions updating actions.lock to avoid startup_failure, but these changes are not included in the diff. Please ensure all intended files are committed.

🔴 HIGH RISK

This command substitution breaks on labels containing spaces because shell word splitting occurs after expansion without interpreting the escapes from printf %q. Use Bash parameter expansion to safely prefix the array elements.

⚪ LOW RISK

Suggestion: This logic correctly enforces that every auto-classification must result in a valid 'type' while respecting the 'max: 1' constraint for the type tier, ensuring no human classification is overridden.

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 Actions documentation push event workflow runs branch github.ref GITHUB_SHA workflow_dispatch default branch permissions GITHUB_TOKEN issues write

💡 Result:

In GitHub Actions, workflow behavior regarding references, triggers, and permissions is governed by the following rules: Push Events and Contexts When a workflow is triggered by a push, the github.ref context provides the fully-formed reference of the branch or tag that was pushed (e.g., refs/heads/branch-name or refs/tags/tag-name) [1][2][3]. The GITHUB_SHA environment variable (or github.sha context) represents the specific commit SHA that triggered the workflow run [1][2]. workflow_dispatch Behavior The workflow_dispatch trigger allows for manual workflow execution [4]. A critical requirement for this trigger is that the workflow file must exist on the repository's default branch to be available for manual execution [5][6][7]. If the file exists on the default branch, you may trigger the workflow against any branch or tag [4][6]. GITHUB_TOKEN and Permissions By default, the GITHUB_TOKEN is often configured with read-only permissions for security [8][9]. If a workflow step attempts to perform a write operation—such as creating an issue, pushing content, or updating a package—and receives a 403 "Resource not accessible by integration" error, it is likely because the required permissions were not explicitly granted [8][9]. To resolve permission issues, you must explicitly define the necessary scope in the workflow or job configuration using the permissions key [10][8][11]: jobs: job_name: runs-on: ubuntu-latest permissions: issues: write contents: write steps: - name: Perform write operation run:... This approach follows the principle of least privilege by granting only the specific access required for the task [10][8][9]. Permissions can be set at the workflow level or scoped to specific jobs [10][8].

Citations:


Restrict label synchronisation to the default branch.

The push trigger has no branch filter. A push to a non-default branch can therefore run sync, fetch .github/labels.json at GITHUB_SHA, and use its contents with issues: write to create or edit repository labels. Apply the job condition to workflow_dispatch and push runs:

if: github.ref == format('refs/heads/{0}', github.event.repository.default_branch)

Serialise repository-level label updates.

GitHub Actions permits concurrent workflow runs by default. Two runs can fetch different payload SHAs and write the same mutable label. An older run can finish last and restore stale colour or description metadata. (docs.github.com)

Add one workflow-level concurrency group so a newer synchronisation supersedes an older run.
