Generated tests are often problematic. The fix raised in the community sync is to require a plan first: state what behavior needs verifying and why, before any test is written. The remaining rules scope what belongs in a test, like behavior this change adds or modifies, one behavior per method, nothing for unreachable states, and nothing whose failure would not indicate a user-visible regression. --- **AI Disclosure** - Model: Claude Opus 5 - Platform/Tool: GitHub Copilot CLI - Human Oversight: Iteratated multiple times and Fully reviewed - Prompt Summary: Add the test plan requirement and test scope rules raised in a community discussion on AI-generated contributions.

| - Test the behavior in the plan. Coverage is not a target. | ||
| - Test the behavior this change adds or modifies. Don't assert the correctness of components this code merely calls. | ||
| - One behavior per test method. No omnibus tests asserting several unrelated things. | ||
| - Don't add a test whose failure would not indicate a user-visible regression. | ||
| - Don't add tests for unreachable states, or tests that only restate the implementation. |

There was a problem hiding this comment.
This is a good set of instructions. I would add this.
- Do not add excessive comments in tests when the intention is clear from the test method name.
