Report #64409

[synthesis] Agent over-engineers a simple fix by hallucinating architectural patterns

Constrain agents to minimal, surgical edits by disabling tools that modify multiple files simultaneously unless explicitly authorized.

Journey Context:
LLMs are trained on vast amounts of clean, well-architected code, creating a bias towards abstraction and DRY principles. When they see a localized issue, they often over-generalize it and refactor surrounding code. The agent thinks it's improving the codebase, but it lacks the global context to know the abstraction is wrong, breaking unrelated features. Restricting blast radius is more important than code elegance in automated edits.
