feat(labels): estate label tooling + auto-triage for new issues - #82
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a canonical label taxonomy, a jq-based issue classifier, an issue triage workflow, and a label synchronisation workflow. The automation applies additive labels and preserves frozen labels. ChangesLabel automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new automation is mergeable with explicit owner awareness: concurrent runs may leave an issue with multiple type labels or make label synchronization report a false failure. Adding per-issue and repository-wide serialization would bound this risk. 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 Actions concurrency groups workflow runs official documentation and gh issue edit --add-label official manual
💡 Result:
GitHub Actions concurrency groups allow you to manage and limit the execution of workflow runs or jobs that share a specific concurrency key, ensuring that only a defined number of jobs or workflows in that group run simultaneously [1][2]. Key details regarding concurrency groups: - Configuration: You can define concurrency at the workflow level or within a specific job [1][2]. - Behavior: By default, if a new workflow run or job starts with the same concurrency key as one already running, GitHub Actions cancels the existing one [1][2]. You can opt to queue jobs instead by setting queue: max, which allows up to 100 jobs to wait in the concurrency group [1][2]. - Dynamic Keys: The concurrency key can be a static string or a dynamic expression utilizing various contexts such as github, inputs, vars, needs, strategy, or matrix [1][2]. Regarding the GitHub CLI command gh issue edit --add-label: The gh issue edit subcommand is used to modify existing issues. To add a label, use the --add-label flag followed by the label name [3][4]. You can also apply changes to multiple issues simultaneously by providing multiple issue numbers [5][6]. Example usage: gh issue edit ISSUE-NUMBER --add-label "label-name" gh issue edit ISSUE-NUMBER-1 ISSUE-NUMBER-2 --add-label "label-name" [5][7] For further reference, the official documentation for controlling workflow concurrency is available on the GitHub Docs site [1], and the manual for the GitHub CLI issue edit command can be found in the GitHub CLI manual [3].
