feat(labels): estate label tooling + auto-triage for new issues - #149
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds generated label definitions, a jq issue classifier, an issue-triage workflow, and a repository label-synchronisation workflow. The workflows fetch repository files through the GitHub API and apply labels without removing existing labels. ChangesLabel automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds automatic label synchronization and issue triage, but malformed configuration, concurrent sync runs, or failed label reads could silently skip updates, fail workflow checks, or apply an incorrect label. It is mergeable with explicit owner awareness and follow-up on these bounded workflow risks. Sequence Diagram(s)sequenceDiagram

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 gh issue view exit status when the API request fails official documentation
💡 Result:
The GitHub CLI (gh) follows standard conventions for exit codes across its commands, including gh issue view [1]. When an API request fails—for instance, due to network issues, invalid parameters, or server-side errors—the command typically returns an exit code of 1 [1]. The general exit code scheme for GitHub CLI is as follows [1]: 0: Successful execution 1: Error (general failure, including API errors) 2: Command canceled 4: Authentication required While 1 is the standard exit code for command failures, the official documentation notes that specific commands may implement additional, command-specific exit codes [2][3][1]. Users relying on exit codes for script automation should be aware of this, though for gh issue view, 1 is the expected result when the underlying API call fails [1]. You can also verify the general exit code documentation by running gh help exit-codes in your terminal [1].

Do not treat a failed label read as an empty label set.
When gh issue view "$NUM" --json labels fails, its non-zero status sets HAVE to []. The classifier can then add bug to an issue already labelled enhancement. Exit successfully before classification when the label read fails or produces no payload.

GitHub Actions concurrency overlapping runs cancel-in-progress false gh label create existing label exit failure official documentation
💡 Result:
Regarding GitHub Actions concurrency and the GitHub CLI (gh) label creation behavior: GitHub Actions Concurrency When using the concurrency key with cancel-in-progress: false, GitHub Actions does not cancel currently running jobs [1][2]. Instead, it ensures that at most one job is running and one job is pending per concurrency group [2]. If a new workflow run is triggered while a job is already running and another is already in the pending state, the previously pending run is canceled, and the newest run takes its place in the pending queue [2]. This behavior prevents excessive queuing while ensuring the most recent requested action is eventually performed [2]. GitHub CLI (gh) Label Creation By default, the gh label create command will fail if the specified label name already exists, typically returning a 422 error (Validation Failed) [3][4]. To make this command idempotent and avoid failure in CI/CD pipelines when the label is already present, you should use the --force flag (or -f) [5][6][4]. When --force is provided, the command will update the existing label's color and description instead of exiting with an error [7][6][4]. Top results: [1][2][6][4]

Serialise repository label mutations.
Two sync jobs can read the same label snapshot because .github/workflows/labels.yml defines no concurrency group. Both jobs can then classify a label as missing and call gh label create. After one job creates the label, the other job's create can fail. If that job performs no other successful mutation, the final failure check exits with status 1 even though the label exists.
Add a repository-scoped concurrency group and retain active runs.

Fail when the canonical payload cannot be read or validated.
|| true masks API and Base64 errors, and [ -s "$PAYLOAD" ] treats them as an intentional missing file. The jq process substitutions also hide validation errors, so invalid frozen or labels values can produce a successful zero-mutation run. Distinguish a missing file from fetch, decode, and schema errors before mutating labels.
