# Register Resolver • AI Agent SDK

> register_resolver: Register a custom resolver for a source name (e.g. ``vault``).

# register\_resolver

Function

> This function is defined in the [**secrets**](https://praison.ai/docs/sdk/reference/praisonaiagents/modules/secrets.md) module.

Register a custom resolver for a source name (e.g. `vault`).

Custom sources extend :data:`SecretRef` beyond the built-in three; the
`SecretRef` validation still applies, so use this together with a
`provider` hint or by resolving `exec`-style commands.
