Make an Ambiguous Instruction Specific

Goal

Replace an ambiguous testing instruction with guidance an agent can apply consistently.

Repository Context

This React application uses Vitest for unit tests.

dashboard/
├── src/
│   ├── components/

├── tests/
├── package.json
└── AGENTS.md

The repository follows this testing policy:

• Behavior changes should have relevant tests added or updated.
• Existing unrelated tests do not need to be rewritten.
• Tests run with pnpm test.

Current AGENTS.md

# Project Instructions

## Development

- Use `pnpm`.
- Keep feature-specific code inside `src/features`.

## Testing

- Test things properly.

## Validation

- Run `pnpm test` before completing behavior changes.

Your Task

Rewrite the ambiguous testing instruction so it clearly tells the agent when tests should be added or updated.

Do not introduce requirements to rewrite unrelated tests.
