feat(labels): estate label tooling + auto-triage for new issues - #65
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe PR adds a generated GitHub label taxonomy, a jq-based issue classifier, an issue triage workflow, and a label synchronisation workflow. The automation is additive-only, preserves frozen labels, and exits successfully when inputs or classifications are unavailable. ChangesLabel automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds automatic label synchronization and issue triage, but the current head still has bounded correctness and integration risks: synchronization may fail, opted-out issues may receive labels, overlapping runs can race, and some issues may remain unclassified. These items should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

GitHub CLI manual gh label create edit --repo repository context
💡 Result:
The GitHub CLI (gh) provides commands for managing repository labels. Both gh label create and gh label edit support the --repo flag to specify the target repository [1][2]. gh label create Used to create a new label or update an existing one if the --force flag is used [1]. Usage: gh label create [flags] Common Flags: -c, --color : Hex color code for the label (e.g., E99695) [1]. -d, --description : Description of the label [1]. -f, --force: Update the label's color and description if it already exists [1]. -R, --repo <[HOST/]OWNER/REPO>: Select a specific repository (e.g., owner/repo) [1][3]. gh label edit Used to update an existing label, including renaming it [2]. Usage: gh label edit [flags] Common Flags: -c, --color : New hex color code [2]. -d, --description : New description [2]. -n, --name : New name for the label [2]. -R, --repo <[HOST/]OWNER/REPO>: Select a specific repository [2]. Example for creating a label in a specific repository: gh label create "bug" --description "Fixes needed" --color FF0000 --repo owner/repo Example for editing a label in a specific repository: gh label edit "bug" --name "critical-bug" --color 000000 --repo owner/repo

Set the repository for the gh label commands.
The workflow has no checkout step and does not set GH_REPO. Pass --repo "$GITHUB_REPOSITORY" to both commands, or set GH_REPO. Without repository context, the commands can fail. Their errors are discarded, so the workflow can report incomplete synchronisation as successful.

Pull Request Overview
While the PR is technically up to standards according to Codacy, several critical gaps must be addressed before merging. Specifically, the PR description mentions the inclusion of .github/workflows/actions.lock and a test suite (tests/test-classifier-parity.py), yet neither are present in the provided diff.
Furthermore, the core classification logic in .github/scripts/classify-issue.jq is highly complex and currently lacks any unit tests. This is a significant risk given the sophisticated regex boundaries used for keyword inflection matching. There is also a critical shell-scripting issue where unquoted command substitutions for label names will fail if those names contain spaces. The 'Human override protection' and 'Sync idempotency' acceptance criteria currently lack evidence of implementation or validation.
About this PR
- The PR description explicitly references updates to
.github/workflows/actions.lockand the existence oftests/test-classifier-parity.py, but these files are missing from the PR. Please ensure all intended files are committed.
Test suggestions
- Prefix classification: 'feat: something' results in the 'enhancement' label.
- Bracket classification: '[p0] critical bug' results in the 'priority:p0' label.
- Keyword inflection: 'failing' or 'crashes' matches the 'bug' type via the kwrx regex logic.
- Human override protection: An issue already labeled 'enhancement' is not re-labeled 'bug' by a 'fix:' prefix.
- Sync idempotency: Running the labels workflow updates the color of 'tech-debt' if it differs from the canonical JSON.
- Frozen protection: Labels in the 'frozen' list (e.g., 'security') are not modified even if their definition in JSON differs.
- Regex boundary validation: Verify 'lean' does not match 'clean' but matches 'leans' in
.github/scripts/classify-issue.jq.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Prefix classification: 'feat: something' results in the 'enhancement' label.
2. Bracket classification: '[p0] critical bug' results in the 'priority:p0' label.
3. Keyword inflection: 'failing' or 'crashes' matches the 'bug' type via the kwrx regex logic.
4. Human override protection: An issue already labeled 'enhancement' is not re-labeled 'bug' by a 'fix:' prefix.
5. Sync idempotency: Running the labels workflow updates the color of 'tech-debt' if it differs from the canonical JSON.
6. Frozen protection: Labels in the 'frozen' list (e.g., 'security') are not modified even if their definition in JSON differs.
7. Regex boundary validation: Verify 'lean' does not match 'clean' but matches 'leans' in `.github/scripts/classify-issue.jq`.
Low confidence findings
- The triage workflow relies on piping
gh apiandbase64output directly into files to bypass checkout restrictions. While this satisfies environment constraints, it introduces a dependency on the runner's pre-installed tools and stable API connectivity for every event.

🟡 MEDIUM RISK
The unquoted printf %q expansion will break if label names contain spaces (e.g., 'good first issue'). Use a quoted, comma-separated join for the --add-label argument instead.

🟡 MEDIUM RISK
The regex construction for inflection-tolerant matching is dense and difficult to maintain without unit tests. As this file is identified as complex and currently lacks coverage, please consider adding a shell-based test script to validate boundary conditions (e.g., ensuring 'lean' doesn't match 'clean').

🟡 MEDIUM RISK
Suggestion: Search the label list using jq instead of awk and cut. The current TSV-based approach is brittle if label names or descriptions contain tabs or special characters.

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.

site:docs.github.com GitHub Actions concurrency group allowed contexts workflow_dispatch inputs github.event issue number cancel-in-progress false
💡 Result:
In GitHub Actions, you can manage the execution of workflow runs using the concurrency group configuration [1][2][3]. For a concurrency group key, you are limited to using specific contexts: github, inputs, and vars [4][3]. While the github context is available, the github.event.issue.number property is not supported within the concurrency key expression because the concurrency key can only be evaluated against limited contexts (github, inputs, vars) [4][3]. Even if the workflow is triggered by an event that contains an issue (such as issue_comment), the concurrency evaluation context does not support nested event properties like github.event.issue [4][3]. To set cancel-in-progress to false, you define the concurrency key and explicitly set cancel-in-progress: false within the concurrency configuration [1][2][3]. This allows multiple runs to queue and execute sequentially rather than canceling existing runs [5]. Example configuration: concurrency: group: my-group-name-${{ inputs.my_input }} cancel-in-progress: false In this example, the concurrency group uses an input from a workflow_dispatch trigger [6][4]. Because the concurrency expression is limited to the allowed contexts (github, inputs, vars), you can dynamically group runs based on user-provided inputs or repository variables [4][3].

🌐 Web query:
site:docs.github.com GitHub Actions concurrency one running one pending queued runs
💡 Result:
In GitHub Actions, the concurrency keyword is used to ensure that only a single job or workflow in a specific concurrency group runs at any given time [1][2]. The behavior regarding queued runs depends on the configuration of the queue property [1][3]. By default, the queue property is set to single [1][4]. In this default mode: - Only one running job or workflow is allowed in the concurrency group [1][2]. - At most one additional job or workflow can be pending (queued) at any time [1][5]. - If a new job or workflow is triggered while another is already pending, the existing pending run is canceled, and the new one takes its place [1][3]. If you wish to allow more runs to queue instead of being automatically canceled, you can set the queue property to max [1][2]. When queue: max is used: - Up to 100 jobs or workflow runs can be pending in the concurrency group [1][4]. - Once this queue limit is reached, any additional triggered runs are canceled [1][2]. Additionally, you can control whether the currently running job is interrupted by setting cancel-in-progress: true [6]. When this is enabled, any currently running job or workflow in the same concurrency group will be canceled when a new job or workflow is triggered [6]. If cancel-in-progress is set to false (the default), the new run will wait until the current one completes [1][5].

🌐 Web query:
site:docs.github.com/en/actions "concurrency" "github.event" "group" "inputs"
💡 Result:
In GitHub Actions, you can use the inputs context to dynamically define a concurrency group [1][2]. This allows you to control concurrency based on specific parameters provided when a workflow is triggered (such as through a workflow_dispatch event) [3]. When configuring the concurrency key in your workflow file, you can reference input values using the standard expression syntax, for example: concurrency: group: ${{ github.workflow }}-${{ inputs.environment_name }} cancel-in-progress: true Key points regarding concurrency and inputs: - Availability: The inputs context is available for use in the concurrency group when the workflow is triggered by an event that supports inputs, such as workflow_dispatch [3]. - Dynamic Groups: By using a dynamic expression like ${{ inputs.some_input }}, you create a unique concurrency group for each distinct input value. Only jobs or workflows sharing the exact same evaluated string will be subject to concurrency limits [1][2]. - Behavior: When a concurrency group is defined, GitHub Actions ensures that only one workflow run or job using that specific key runs at a time [1][2]. By default, if a new run with the same key starts, it will cancel any currently pending runs [1][4]. You can also enable queuing by setting queue: max to allow up to 100 runs to wait in line instead of being canceled [1][5]. - Scoping: Concurrency can be defined at the workflow level (top-level) or the job level (jobs.<job_id>.concurrency) [1][6]. Job-level concurrency allows other jobs within the same workflow to continue running while a specific job is limited by the concurrency group [6].

Serialise triage runs per issue.
The triggers can overlap. Each run reads HAVE before gh issue edit, so a stale run may apply labels without seeing a newer classification and bypass the max-1 safeguard. Add a per-issue concurrency group keyed by the resolved issue number with cancel-in-progress: false.

Add a retry after label synchronisation
When .github/workflows/labels.yml creates labels after the empty-apply branch runs, no event starts triage again. The issue remains unlabelled until manual dispatch or reopening. Add a post-synchronisation trigger or an equivalent retry.

GitHub CLI gh label create existing label --force documentation
💡 Result:
To use the GitHub CLI to create or update a label named "documentation," use the following command [1]: gh label create documentation --force The --force flag is essential when working with existing labels [1][2]. Without it, the command will fail with an error if the label already exists [2]. When --force is included, the GitHub CLI will update the existing label's description and color to match the parameters provided in your command [1][2]. If you wish to specify a color or description while creating or updating the label, you can add those flags as well [1]: gh label create documentation --color "0075ca" --description "Documentation related issues" --force In this command: --color: Sets the label's color using a 6-character hex value (the # prefix is optional) [1][2]. --description: Provides a text description for the label [1][2]. --force: Ensures the command succeeds by updating the label if it already exists [1][2].

GitHub Actions concurrency workflow runs group cancel-in-progress false documentation
💡 Result:
In GitHub Actions, setting cancel-in-progress: false (which is the default) does not mean that no jobs will ever be canceled [1][2]. A concurrency group is designed to maintain a strict limit on execution: at any given time, a group can have at most one job or workflow run in progress and at most one job or workflow run in a pending (queued) state [3][4][5]. The cancel-in-progress setting specifically controls what happens to the currently running job when a new run is triggered [4][2]: 1. When cancel-in-progress: true: If a run is already in progress in the group, GitHub Actions cancels the in-progress run, allowing the new run to proceed [3][2]. 2. When cancel-in-progress: false: The currently running job is protected and allowed to finish [1][2]. However, if a new run arrives while another run is already pending (waiting in the queue), the existing pending run will be canceled to make room for the newest run [3][4][5]. In summary, cancel-in-progress: false prevents the interruption of the currently running job, but it does not prevent the cancellation of a job that is currently queued [1]. The system always ensures that only the most recent queued run occupies the single available "pending" slot [4][1].

Serialise label synchronisation runs.
Concurrent runs can both read the same missing label. One run can create it while the other receives a gh label create failure. If no other mutation succeeds, Lines 101–103 can fail the second workflow even though the label exists.
Add a repository-scoped concurrency group with cancel-in-progress: false.

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.lockas[]. That lock is keyed by workflow path and refuses any workflow it does not list — astartup_failure, which produces no check run and is therefore silent.gh actions-lockcannot add these: it records action versions, and both workflows deliberately use none.See
