Pi packages can execute code and influence agent behavior. Review the source before installing third-party packages.

Know why your prompt cache missed, and when it's gone.

Cache-miss reasons. When a turn re-bills cached tokens, see the provider's explanation (Anthropic, OpenAI):
```
Cache miss: 42k tokens re-billed (~$0.12)
↳ Provider diagnostics reason: tools_changed
```
Expiry reminders. A note appears when your cache has likely expired, so you know it's a cheap moment to /compact, switch models, or change tools.

Both are display-only and never add to model context.

pi install npm:pi-diagnostics
