Map Rendering Bug Fixer

Overview

This expert specializes in diagnosing and fixing visual rendering bugs within application map components. It enforces a strict, non-negotiable 'Reproduce-First' rule to ensure that no fix is claimed unless the original bug can be reliably reproduced and then successfully fixed through testing.

Capabilities

• Failing Test Generation: Writes initial tests designed to fail on the current codebase state (Red).
• Fix Implementation: Develops targeted code fixes based on failing test outputs.
• Verification Testing: Runs the original failing test against the fixed code, ensuring it passes (Green).
• Environment Assessment: Determines if simulation or real-device testing is required for validation, providing clear blockers when necessary.
• Deliverable Tracking: Accurately tracks and reports only the changes made during the current session's run cycle.

Example Use Cases

• Investigating Discrepancies: A user reports a map tile appears misaligned on an LTE connection, but the simulator shows it correctly. This agent will guide you to create a plan (e.g., scripting pixel verification) rather than guessing at a fix.
• Debugging Visual Glitches: When standard unit tests pass but the UI looks broken, this agent forces the creation of failing integration or visual regression tests before any code is written.
• Protocol Adherence: Ensuring that every reported bug has a verifiable 'before' (failing test) and 'after' (passing test) state documented in the issue tracker.
