feat(labels): estate label tooling + auto-triage for new issues - #21
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThis change adds a generated GitHub label taxonomy, a jq-based issue classifier, and two GitHub Actions workflows. One workflow synchronises labels. The other applies additive labels to newly opened or reopened issues. ChangesIssue label automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new automatic labeling can still modify issues that opt out of automation and may add conflicting or duplicate labels when label reads fail or existing names differ only by case. These are bounded correctness risks that should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Honour status:do-not-automate before classification.
An issue that already has status:do-not-automate still reaches gh issue edit. This conflicts with the canonical label description, which says bots and sweeps must not touch that issue. Exit successfully before classification when HAVE contains this label.

Pull Request Overview
The PR implements a custom label taxonomy and an automated triage system using jq and GitHub CLI, avoiding external actions or Python as per requirements. While the overall structure is sound and Codacy grades are up to standards, there is a critical functional bug in the shell-scripting logic regarding label names containing spaces; the current printf %q approach will cause gh issue edit to fail when applying labels like 'area: design'.
Furthermore, the core classification logic in .github/scripts/classify-issue.jq is highly complex (164 lines) and currently lacks any unit tests. All defined acceptance criteria for classification behavior (tier-locking, prefix matching, keyword inflection) remain unverified within the PR scope. Given the density of the regex-based engine, this represents a high risk for regressions. It is recommended to implement a test harness for the JQ script before merging.
About this PR
- The implementation of the classification engine in JQ is logic-dense and lacks a verification suite. Without tests for the keyword inflection and tier-locking logic, future changes to the taxonomy or classifier are likely to introduce bugs.
- The triage workflow's dependency on fetching script content via API using $GITHUB_SHA makes the core functionality vulnerable to GitHub API availability or rate limiting during issue events. Consider if a local checkout is feasible given the workflow environment.
Test suggestions
- Verify that 'feat: ...' titles correctly result in the 'enhancement' label being added.
- Verify that existing labels on an issue prevent the bot from adding a conflicting label in the same tier (e.g., existing 'bug' prevents adding 'enhancement').
- Verify that bracketed tags like '[p0]' correctly map to priority labels.
- Verify that the labels sync workflow updates descriptions and colors but skips 'frozen' labels.
- Verify the classifier is silent when no confident match is found or no type label is determined.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify that 'feat: ...' titles correctly result in the 'enhancement' label being added.
2. Verify that existing labels on an issue prevent the bot from adding a conflicting label in the same tier (e.g., existing 'bug' prevents adding 'enhancement').
3. Verify that bracketed tags like '[p0]' correctly map to priority labels.
4. Verify that the labels sync workflow updates descriptions and colors but skips 'frozen' labels.
5. Verify the classifier is silent when no confident match is found or no type label is determined.

🔴 HIGH RISK
The kwrx function implements a sophisticated inflection engine for keyword matching using lookarounds. This manual approach to stem handling (e.g., handling 'ing', 'ation', 'ies') is logic-dense and represents a high risk for regressions. Create a comprehensive test suite for this JQ script using a Bash script that asserts output labels against a range of input titles and edge cases.

🟡 MEDIUM RISK
The printf %q approach fails to handle labels with spaces correctly. Use a Bash array to safely collect and pass the --add-label arguments.
Example refactor:
apply_args=()
for label in "${apply[@]}"; do
apply_args+=("--add-label" "$label")
done
gh issue edit "$ISSUE_NUMBER" "${apply_args[@]}"| exit 0 | ||

| TITLE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" --json title --jq .title) || exit 0 |

⚪ LOW RISK
Suggestion: Combine the multiple gh issue view calls into a single call using --json title,labels to improve performance and ensure consistency.

⚪ LOW RISK
Nitpick: Parsing GitHub labels using TSV and 'read' may fail if label names contain tab characters. While unlikely in this taxonomy, it is a point of fragility in the sync logic.

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.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Stop when the existing-label read fails.
If the gh issue view call at Line [83] fails, HAVE becomes [] and classification continues. The classifier then treats the issue as unlabelled. It can add a second label from a max-1 tier beside a human or issue-template label. The conflicting label remains because this workflow never removes labels.
Exit successfully before classification when the read fails. Do not convert an API error into an empty label set.

GitHub REST API repository labels name case insensitive duplicate label create behaviour
💡 Result:
GitHub repository labels are effectively case-insensitive [1][2]. You cannot create two labels in the same repository that differ only by their casing (e.g., if a label named "bug" exists, you cannot create a new label named "BUG") [2]. If you attempt to use the GitHub REST API POST /repos/{owner}/{repo}/labels endpoint to create a label with a name that already exists in the repository—regardless of case—the API will return a 422 Unprocessable Entity error because the label name is already taken [3]. When building integrations that interact with GitHub labels, this behavior is a common source of friction. Because the API does not automatically "adopt" or link to the existing label if you attempt a duplicate creation, many developers and tool maintainers (such as those for the Terraform GitHub provider) implement a "check-first" pattern [3]. This pattern involves: 1. Fetching the list of existing labels in the repository. 2. Checking if a label with the desired name (case-insensitive) already exists. 3. If it exists, using the PATCH endpoint to update it or simply proceeding with the existing label. 4. If it does not exist, using the POST endpoint to create it [3]. Note that while the creation and existence check are effectively case-insensitive, some other GitHub services or search queries might exhibit inconsistent behavior regarding case sensitivity, requiring developers to normalize casing (e.g., to lowercase) before performing operations [2][4].

site:docs.github.com REST create a label 422 name already exists case insensitive repository labels
💡 Result:
When using the GitHub REST API to create a label in a repository, the API returns a 422 Unprocessable Entity status code if a label with the same name already exists [1][2]. GitHub repository label names are case-insensitive [1][3]. Consequently, attempting to create a new label with a name that is identical to an existing label—ignoring case—will trigger this 422 validation error [1][2]. For example, if a label named "Bug" already exists, any attempt to create a label named "bug" or "BUG" will be rejected by the API [1].

Match label names case-insensitively across sync and triage.
If the repository has Security and the taxonomy requires security, the exact lookup leaves cur empty. GitHub rejects the duplicate create request with HTTP 422, so the sync does not adopt the existing label. Triage then compares security with Security using exact Bash equality and does not apply the label.
Use case-insensitive comparisons in both workflows. Add the matching repository name to apply, and preserve the frozen-label rule.
