feat(labels): estate label tooling + auto-triage for new issues - #37
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a canonical GitHub label taxonomy, a jq issue classifier, an automatic issue-triage workflow, and an additive label-synchronisation workflow. ChangesLabel automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change adds repository-wide label synchronization and automatic issue labeling, but the current implementation can apply unmerged definitions, fail to maintain canonical labels, ignore explicit opt-outs, duplicate classifications after read failures, and overwrite newer label settings during concurrent runs. The PR is not merge-ready until these bounded correctness and operational risks are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

GitHub REST API issue labels conditional update If-Match ETag gh issue edit --add-label atomic
💡 Result:
The GitHub REST API does not provide a native mechanism to perform atomic "add-label" operations using ETag headers (If-Match) to prevent race conditions during updates [1][2][3]. While GitHub supports ETag-based conditional requests using the If-None-Match header, this feature is designed for optimizing read operations and rate-limit management (returning a 304 Not Modified status if the resource has not changed) [4][5][6]. It is not intended for enabling conditional state-changing writes (atomic patches) [4]. To manage labels on an issue, the API provides the following distinct endpoints: 1. Add labels: POST /repos/{owner}/{repo}/issues/{issue_number}/labels [2][3]. 2. Set (replace) labels: PUT /repos/{owner}/{repo}/issues/{issue_number}/labels [2][3]. Because there is no atomic "add if current labels match X" functionality, applications requiring strict consistency to prevent race conditions typically implement custom locking mechanisms (e.g., in a database or distributed lock service) or use a "read-modify-write" pattern. Note that the "read-modify-write" pattern remains susceptible to race conditions between the read and the update unless managed externally, as the GitHub API does not support optimistic locking (using If-Match) for issue modification endpoints.

GitHub CLI gh label create repository context GH_REPO --repo local git repository manual
💡 Result:
To create a label using the GitHub CLI (gh), you use the gh label create command [1][2]. Repository Context The GitHub CLI automatically infers the repository context from the Git remotes configured in your current working directory [3]. If you are running the command inside a local Git repository, gh will target that repository by default [4]. To target a different repository—or if you are not in a directory with a linked repository—you can explicitly specify the target using the --repo (or -R) flag [1][3]. Command Syntax The general syntax for creating a label is [1][5]: gh label create [flags] Flags: -c, --color : Sets the label color as a 6-character hexadecimal value [1][5]. If omitted, a random color is assigned [1][6]. -d, --description : Adds an optional description for the label [1][7]. -f, --force: Updates the label's color and description if the label already exists (making the command idempotent) [1][7]. -R, --repo <[HOST/]OWNER/REPO>: Specifies the target repository [1][8]. Example To create a label named bug in your current repository with a description and a custom color: gh label create bug --description "Something isn't working" --color E99695 [1][6] To target a specific repository explicitly: gh label create bug --repo OWNER/REPO --color FF0000 [7][3]

Set the repository for the gh label commands and fail on mutation errors.
This job does not check out the repository, so gh label create and gh label edit need GH_REPO or --repo. Without either option, label mutations can fail.
The && commands do not stop the loop, and their errors are redirected. The workflow can therefore succeed without creating or updating labels. Set GH_REPO: ${{ github.repository }} and exit when a mutation fails.

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.

Stop when the existing-label read fails.
If the label read fails, HAVE becomes []. The classifier can then add a second type label, such as bug beside an existing enhancement label. Exit successfully without classification when the read fails.

GitHub Actions events that trigger workflows push GITHUB_SHA workflow_dispatch selected ref GITHUB_SHA official documentation
💡 Result:
In GitHub Actions, the value of GITHUB_SHA and the behavior of workflow triggers depend on the specific event that initiated the run [1][2]. For the push event, GITHUB_SHA represents the commit SHA that was pushed to the repository [1]. For the workflow_dispatch event, GITHUB_SHA is the SHA of the last commit on the specific branch or tag selected when the workflow is manually triggered [3]. The workflow_dispatch event allows users to manually trigger a workflow via the GitHub UI, CLI, or API, provided the workflow file exists on the default branch [4][5][3]. When triggering the workflow, you can select the target branch or tag [3], and GITHUB_SHA will correspond to the most recent commit on that selected reference [3]. In summary: - push: GITHUB_SHA is the specific commit SHA that triggered the push [1]. - workflow_dispatch: GITHUB_SHA is the last commit SHA of the branch or tag selected at the time of manual dispatch [3]. Official documentation emphasizes that GITHUB_SHA behavior is event-dependent [1][2]. You can always refer to the official GitHub Actions documentation on events that trigger workflows for detailed tables mapping events to their respective GITHUB_SHA and GITHUB_REF behaviors [6][7].

Restrict label synchronisation to the default branch.
The push trigger has no branch filter. The job fetches .github/labels.json at $GITHUB_SHA, so a feature-branch push can apply unmerged label definitions to repository-wide labels. workflow_dispatch can also target a selected ref. Restrict the job to the default branch, or fetch the manifest from that branch before mutating labels.

Prevent overlapping label synchronisation runs.
The triggers can start concurrent runs. A run for an older commit can finish later and overwrite newer label colours or descriptions. Add a repository-scoped concurrency group to prevent overlapping mutations.

GitHub REST API issue labels label names case insensitive create duplicate name behaviour
💡 Result:
GitHub issue labels are treated as case-insensitive for the purpose of uniqueness, meaning you cannot create a new label if an existing label already exists with the same name, even if the casing differs [1][2]. When you attempt to create a label via the GitHub REST API (POST /repos/{owner}/{repo}/labels) that conflicts with an existing label name (case-insensitively), the API will return a 422 Unprocessable Entity error with a message indicating that the label already exists (e.g., "Label already exists") [3][2][4]. Key behavioral points regarding this case-insensitive uniqueness: 1. Collision: If you try to create a label named "Bug" when "bug" already exists, the request will fail with a 422 error [3][2]. 2. Storage: While the API enforces case-insensitive uniqueness, GitHub preserves the original casing of the label as it was first created [2]. 3. Client-Side Handling: Because of this behavior, tools and automation scripts that manage labels often need to perform a case-insensitive lookup of existing labels before attempting a creation [1][5][2]. If a label is found but the casing differs, the recommended approach for automation is to use the Update a label endpoint (PATCH /repos/{owner}/{repo}/labels/{name}) to rename the existing label to the desired casing rather than attempting to create a new one [2]. This case-insensitive constraint applies to the API's validation logic to prevent duplicate labels in a repository [2].

Match existing label names case-insensitively.
The case-sensitive $1==n lookup misses labels whose casing differs. The workflow then calls gh label create, which GitHub may reject with 422 because label names are unique case-insensitively. The existing label is not reconciled.
Compare normalised names and retain the existing name for gh label edit.
