feat(labels): estate label tooling + auto-triage for new issues - #38
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change adds generated label definitions, a jq-based issue classifier, an issue triage workflow, and a label synchronisation workflow. The workflows use GitHub CLI API calls, preserve frozen labels, and handle uncertain or failed operations without failing unnecessarily. ChangesIssue label automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new label synchronization workflow can treat non-404 API or payload-decoding failures as success, leaving repository labels stale without a visible failure. This is a bounded operational correctness risk; the PR is mergeable with explicit owner follow-up to distinguish a missing file from fetch or decoding errors. 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.

Pull Request Overview
The implementation successfully adheres to the 'no-Python' and 'no-external-actions' constraints for the core workflows; however, there are several implementation gaps and risks. Most critically, the logic for generating regex patterns for keywords ending in 'y' is flawed, which will cause silent classification failures for numerous terms. Additionally, the PR description references a Python-based parity test suite and a lockfile update that are entirely missing from the provided changes. While the use of shell and JQ is robust for the environment, the lack of automated validation for the complex classification script and the inefficient label-searching loop in the sync workflow should be addressed before merging.
About this PR
- The PR description mentions updating '.github/workflows/actions.lock' to include the new workflows, but this file is missing from the diff. This may cause startup failures in environments enforcing strict action locking.
- The code references a parity test suite ('tests/test-classifier-parity.py') that is not included in the diff. Without these tests, verifying the complex regex and precedence logic in the JQ script is difficult. Ensure these are either included or the reference is corrected if they belong in a separate repository.
Test suggestions
- Verify that a conventional commit prefix (e.g., 'fix:') correctly assigns the 'bug' type label.
- Verify that 'bracket tags' (e.g., '[p1]') correctly assign priority labels.
- Confirm that the classifier does not add a 'type' label if one is already present on the issue (no override).
- Ensure that a missing 'frozen' label (e.g., 'security') is created by the sync workflow.
- Ensure that an existing 'frozen' label's color/description is not updated even if it differs from the canonical set.
- Verify that the triage workflow exits 0 even if the GitHub API call to fetch rules fails.
- Verify the 'silent when unsure' behavior for titles that do not trigger prefix, bracket, or keyword-type rules.
- Add a validation workflow to unit test the .github/scripts/classify-issue.jq script logic.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify that a conventional commit prefix (e.g., 'fix:') correctly assigns the 'bug' type label.
2. Verify that 'bracket tags' (e.g., '[p1]') correctly assign priority labels.
3. Confirm that the classifier does not add a 'type' label if one is already present on the issue (no override).
4. Ensure that a missing 'frozen' label (e.g., 'security') is created by the sync workflow.
5. Ensure that an existing 'frozen' label's color/description is not updated even if it differs from the canonical set.
6. Verify that the triage workflow exits 0 even if the GitHub API call to fetch rules fails.
7. Verify the 'silent when unsure' behavior for titles that do not trigger prefix, bracket, or keyword-type rules.
8. Add a validation workflow to unit test the .github/scripts/classify-issue.jq script logic.

🟡 MEDIUM RISK
This script contains non-trivial logic for dynamic regex generation and label precedence handling. Given its role as the engine for estate-wide triage, consider adding a validation workflow to ensure that changes to the taxonomy or script logic do not regress on a standard corpus of issue titles.
Try running the following prompt in your IDE agent:
Create a GitHub Action workflow and a test dataset (JSON) to unit test the '.github/scripts/classify-issue.jq' script. The tests should cover conventional commit prefixes, bracket tags, and keyword area hits, ensuring the precedence rules and max-1 tier enforcement work as expected.

🟡 MEDIUM RISK
The keyword taxonomy contains an inconsistency: stem-based keywords (e.g., 'vulnerabilit') correctly match plural forms via the 'kwrx' logic, but full-word keywords ending in 'y' (e.g., 'theory', 'latency', 'memory') will match incorrect forms like 'theoryies' instead of 'theories'. Standardize keywords ending in 'y' to use their stems in the JSON configuration.

⚪ LOW RISK
Suggestion: The temporary directory created for rules and classification scripts should be cleaned up at the end of the run.
This might be a simple fix:
| work=$(mktemp -d); RULES=$work/rules.json; SCRIPT=$work/classify.jq | |
| work=$(mktemp -d); trap 'rm -rf "$work"' EXIT; RULES=$work/rules.json; SCRIPT=$work/classify.jq |

⚪ LOW RISK
Suggestion: The loop performs an external 'awk' call for every label in the canonical set to find matches in the 'existing' list. For better performance and robustness in repositories with many labels, consider loading the 'existing' labels into a Bash associative array once before entering the loop.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Fail when the label payload cannot be fetched or decoded.
Line 52 suppresses all gh api and base64 -d failures. Line 53 then exits successfully as if .github/labels.json were absent. A transient API failure or an invalid payload can therefore silently skip label synchronisation.
Handle a 404 as the only no-op case. Fail for other fetch and decode errors.
