Pull Request Overview
This PR implements a standardized label taxonomy and an automated triage system using jq-based classification. The approach is well-aligned with estate security policies by avoiding external GitHub Actions and Python dependencies. However, there is a significant risk regarding the verification of the classification logic: the code references a test suite (tests/test-classifier-parity.py) that is not included in the PR.
While Codacy marks the PR as up to standards, the label synchronization logic in .github/workflows/labels.yml is fragile due to the use of TSV parsing, which may fail on label descriptions containing tabs or newlines. Additionally, the triage logic's reliance on hardcoded SHA references and the missing lockfile updates mentioned in the description should be addressed to ensure long-term maintainability and consistency.
About this PR
- The script
.github/scripts/classify-issue.jqreferences a test suitetests/test-classifier-parity.pywhich is not included in this PR. Given the complexity of the jq logic for tier precedence and human-override protection, this test suite should be committed to ensure the classifier's behavior is verified. - The PR description mentions updating
.github/workflows/actions.lock, but this file is missing from the PR diff. Please ensure all necessary configuration changes are included to maintain consistency with the new workflows.
Test suggestions
- Verify bracket tag extraction (e.g., [docs]) correctly maps to labels
- Verify conventional commit prefix extraction (e.g., 'feat: ') correctly maps to labels
- Verify keyword inflection matching (e.g., 'theorems' matches 'theorem' rule)
- Verify precedence resolution when multiple types or priorities are detected
- Verify human override protection: classifier must skip a tier if the issue already has a label in it
- Verify mandatory type requirement: classifier returns nothing if no Type can be determined
- Verify label sync idempotency: creates missing and updates existing (color/description) without deleting
- Verify 'frozen' label protection in the sync workflow
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify bracket tag extraction (e.g., [docs]) correctly maps to labels
2. Verify conventional commit prefix extraction (e.g., 'feat: ') correctly maps to labels
3. Verify keyword inflection matching (e.g., 'theorems' matches 'theorem' rule)
4. Verify precedence resolution when multiple types or priorities are detected
5. Verify human override protection: classifier must skip a tier if the issue already has a label in it
6. Verify mandatory type requirement: classifier returns nothing if no Type can be determined
7. Verify label sync idempotency: creates missing and updates existing (color/description) without deleting

🟡 MEDIUM RISK
Suggestion: The use of @tsv and awk for parsing label data is fragile. If a label description contains a newline or a tab character, the record will be split incorrectly, potentially causing the sync to fail or create mangled labels. Consider using JSON for the entire pipeline to ensure robustness.
Try running the following prompt in your IDE agent:
Refactor the
syncjob in.github/workflows/labels.ymlto process the existing labels as a JSON object usingjqinstead of TSV andawk. This ensures that label descriptions containing newlines or tabs do not break the parsing logic.

⚪ LOW RISK
Nitpick: Silencing stderr (2>&1) for gh label commands hides potential errors such as permission issues or API limits. It is better to allow stderr to be logged or to provide an explicit error message on failure to aid debugging.

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.

Honour status:do-not-automate before producing labels.
.github/labels.json Lines 199-202 define this label as “Bots and sweeps must not touch this issue”. Line 157 only locks the status tier. If an issue template supplies this label, or a maintainer reopens an opted-out issue, the classifier can still return type and area labels for label-triage.yml to apply.
Return an empty result when $have contains status:do-not-automate.

GitHub Actions documentation github.ref_name workflow_dispatch push event GITHUB_SHA branch default branch
💡 Result:
In GitHub Actions, the context github.ref_name and variables GITHUB_REF and GITHUB_SHA behave differently depending on the trigger event [1][2][3]. github.ref_name and GITHUB_REF The github.ref_name context provides the short name of the branch or tag that triggered the workflow [1][4]. The GITHUB_REF environment variable provides the fully-formed reference (e.g., refs/heads/branch-name or refs/tags/tag-name) [1][3]. For a push event, these values correspond to the specific branch or tag that was pushed [1][5]. For a workflow_dispatch event, these values represent the branch from which the workflow was manually triggered [6][2]. Importantly, if you trigger a workflow via workflow_dispatch from the GitHub UI, it defaults to running against the repository's default branch unless a different branch is selected in the manual trigger menu [6][7]. GITHUB_SHA The GITHUB_SHA environment variable represents the commit SHA that triggered the workflow [3]. For push events, this is the tip commit of the pushed ref [5]. For workflow_dispatch events, GITHUB_SHA is the commit SHA of the branch head at the time the workflow was triggered [7][8]. Default Branch To reliably identify or reference the repository's default branch, use the GITHUB_DEFAULT_BRANCH environment variable [9]. This variable is automatically set by the runner and is preferable to hardcoding branch names like "main" or "master" [9]. Summary Table Event | github.ref_name | GITHUB_SHA --- | --- | --- push | The pushed branch or tag name [1] | The pushed commit SHA [5] workflow_dispatch | The branch name where triggered [6] | The commit SHA of the branch head [8] If your workflow needs to differentiate between the current branch and the default branch, you can compare github.ref_name against env.GITHUB_DEFAULT_BRANCH [9].

Restrict label synchronisation to the default branch.
The push trigger runs for every branch. A push to an unmerged branch can supply that branch’s .github/labels.json at GITHUB_SHA to a job with issues: write, which can modify live repository labels.
Add a job condition that allows synchronisation only when github.ref_name equals github.event.repository.default_branch. Apply the condition to manual dispatches so users cannot select a non-default branch.

GitHub REST API create a label duplicate already exists response 422 official documentation gh label create
💡 Result:
When using the GitHub REST API to create a label via the POST /repos/{owner}/{repo}/labels endpoint, attempting to create a label with a name that already exists in the repository will result in an HTTP 422 Unprocessable Entity response [1][2][3]. The response body will typically include a message indicating a validation failure and a specific error code of already_exists [4][5][2]. A common response structure looks like this: { "message": "Validation Failed", "documentation_url": "https://docs.github.com/rest/issues/labels#create-a-label", "errors": [ { "resource": "Label", "field": "name", "code": "already_exists", "message": "already exists" } ] } Similarly, when using the GitHub CLI (gh label create), the command will fail with an error message reflecting this API response [6], as the command performs a direct API call rather than an idempotent operation [6][7]. If you require idempotent behavior (creating only if it does not exist, or updating if it does), you must implement logic in your client-side code to check for the label's existence first (e.g., via a GET request) and then proceed to create or update it accordingly [4][7].

Serialise concurrent label mutations.
If concurrent runs both read a label as missing, both call gh label create. GitHub rejects the second create with already_exists. That run then meets the failed > 0 and created + updated == 0 condition at lines 101-103 and exits with status 1.
Add a repository-scoped concurrency group with cancel-in-progress: false.
