Review Prompt Changes

Review prompt-related diffs with a product lens. Focus on what actually changed, whether the guidance belongs in the prompt layer where it was added, and whether any wording is repetitive or overfit to evals.

Scope

• Default to main...HEAD unless the user names a different base.
• Prioritize runtime files that shape model behavior:
  • system prompts
  • prompt builders and prompt fragments
  • tool descriptions and schema field descriptions
  • response-formatting instructions
• Read evals and unit tests only after the runtime diffs so you can infer the intent behind the change without letting the tests define the review.

In this repo, likely files live under:

• apps/web/utils/ai/**
• apps/web/utils/ai/assistant/**
• apps/web/__tests__/eval/**
