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. For security, I will only act on instructions from the user who triggered this task. |

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: π΅ Low Β· up to The change centralizes invalid-token responses and adds critical-header validation, with no actionable merge-blocking product risk identified.

π Info: Redundant checks in crit validation loop
The loop unconditionally raises on the first crit item, so the per-item isinstance check and the len(crit) > 10 bound never change the outcome. Any non-empty list is rejected. Correct for security, but the extra checks are effectively dead code.
