What problem does it solve?
Prompt and tool-description changes in AI products often accumulate bloated, repetitive, or eval-driven instructions that hurt real product behavior. This Skill audits prompt-related diffs in a branch or PR so reviewers can judge whether each change belongs in the prompt layer where it was added.
Core Features & Use Cases
- Prompt Diff Audit: Scans changed files against a base branch (default
main...HEAD) and prioritizes system prompts, prompt builders, tool descriptions, and schema field descriptions.
- Guidance Classification: Buckets findings into behavior changes, product-helpful guidance, heavy or eval-shaped guidance, and repeated instructions across prompt layers.
- Structured Review Output: Produces Findings (ordered by severity with file and line references), a What Changed summary, and a Net Read with trim targets.
- Use Case: Before merging a PR that edits system prompts and tool descriptions in
apps/web/utils/ai/**, run this review to catch duplicated instructions between the main prompt and tool descriptions and flag wording added only to satisfy evals.
