Do Not Guess At Performance
When an app feels slow, measure render time, network time, query time, and bundle size before asking the agent to optimize.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
Profile /dashboard. List largest network request, slowest query, heaviest component, and largest bundle chunk. Optimize only the biggest measured issue.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?
