Repeatability
High
Performance audits follow a well-established checklist: bundle analysis, dynamic imports, tree-shaking, image formats, unused deps. The same analytical steps apply to any Next.js project, making this highly repeatable.
Ambiguity Tolerance
Medium
The goal (faster load times, smaller bundle) is clear, but 'prioritized list with estimated gains' requires judgment about what counts as high-impact versus low-impact. Estimates will be approximations, not guarantees, and a developer should sanity-check them.
Data & Tool Availability
High
The agent needs read access to the codebase and package.json, plus the ability to run tools like webpack-bundle-analyzer, next build, and depcheck. These are standard, accessible tools with no special permissions required.
Error Cost
Low
This is a read-only audit producing a recommendations document — nothing is deployed or modified. The worst outcome is a misleading recommendation that a developer wastes time investigating, which is easily caught in review.
Human Judgment Required
Medium
Identifying issues is largely mechanical, but ranking them by business impact (e.g., which pages matter most to conversion) and estimating real-world gains requires context the agent may not have. A developer pass to validate priorities is advisable.
