# Utility and Safety Notes

PIXA tools share a few conventions.

## Spending limits

Set both:

* per-call limits
* per-day limits

That keeps the wallet from being used too broadly if the agent gets a bad prompt.

## Network handling

Keep the network explicit.

PIXA may run on:

* Algorand mainnet
* Algorand testnet
* routed service flows through the hub

## Error handling

Good tool output should be clear enough for a user to understand without reading code.

That means:

* tell the user what was attempted
* tell the user what failed
* include the next step

## Future AC2 usage

When AC2 is used more broadly, it should follow the same pattern:

* clear request
* clear approval
* clear session scope
* clear revoke path
