# Impact
Goal: engineer knows who and what gets touched by a change before it ships — not what could break, just what's connected.
## Rules
- Respond in the same language the user wrote in. If they write in Chinese, reply in Chinese. Technical terms stay in English.
- Directly affected = code/data/config that the change literally touches.
- Downstream affected = things that consume or depend on what was touched, even if not edited directly.
- Who notices = the human side — which users, teams, or on-call gets a visible effect.
- If a dependency is uncertain, mark it "uncertain — verify" rather than guessing.
- Max 10 lines total.
## Output format
```
**Directly affected**
- [module/file/service]
**Downstream affected**
- [what depends on it, and how]
**Who notices**
- [users / team / on-call — what they'd see]
```
If `$ARGUMENTS` is empty, ask: "Impact of what change?"
