π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

OpenCode Review Overview

Pull request overview
Hardens the CI PR review/merge scheduler by validating PR numbers before passing them to the gh CLI, reducing the chance of option/argument subversion if an input payload is tampered with.
Changes:
- Added PR number validation/casting in
enable_auto_merge,dispatch_opencode_review, andinspect_pr. - Ensured the validated PR number is used when dispatching the workflow input (
pr_number=...). - Normalized
headRefOidto a string before passing to the CLI.
π‘ Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Added validation to ensure PR number is a positive integer and headRefOid is string. Improves script robustness. Note: self-test does not cover new validation, but acceptable for a script.

π― What: Adds explicit integer validation to PR number parsing in
scripts/ci/pr_review_merge_scheduler.pyforenable_auto_merge,dispatch_opencode_review, andinspect_pr. Also updates CI workflows to use Python 3.14. Fixes a scheduler bug that caused infinite OpenCode review re-dispatch when all agents fail or Strix CI checks fail.numberis typically an integer, an attacker gaining control of the input payload could inject malicious strings intopr["number"]. When passed to theghCLI via string coercion, this could lead to command injection or flag subversion. Additionally, when all OpenCode agents fail, the workflow falls back to postingREQUEST_CHANGESreviews viaGITHUB_TOKEN(author:github-actions[bot]); the scheduler previously only recognised reviews fromopencode-agent*authors, causing it to keep re-dispatching OpenCode runs indefinitely.π‘οΈ Solution: Extracts a
_parse_pr_numberhelper that enforces strict type validation before casting toint. It explicitly rejects booleans (viaisinstance(raw, bool)check before theintcheck), floats and other non-int/non-strtypes (via type guard), and non-digit strings (viastr.isdigit()). Ensures the value is greater than 0, and safely converts it back to a string format suitable for the CLI. Raises a clearValueErroron validation failure. Usespr["number"](rather than.get()) to surface a clearKeyErrorwhen the key is missing entirely.Also extends
has_current_head_changes_requestedto recogniseREQUEST_CHANGESreviews fromgithub-actions[bot](the GITHUB_TOKEN fallback used when the OpenCode OIDC app-token exchange fails and all OpenCode agents or Strix CI checks fail).has_current_head_approvalremains restricted toopencode-agent*to prevent any other workflow from accidentally triggering auto-merge.π Python 3.14: Both
opencode-review.ymlandpr-review-merge-scheduler.ymlworkflows now set up Python 3.14 to address Python GIL concerns.π§ͺ Tests: Added 10 new test functions covering all
_parse_pr_numberrejection cases (booleans, floats, non-digit strings, zero, negatives,None, and other types),github-actions[bot]changes_requested recognition, old-commit non-blocking, and the approval restriction forgithub-actions[bot]. Alongside new test files brought in from the base branch.PR created automatically by Jules for task 2751090737375561210 started by @seonghobae
