# Function nemo_relay_scope_register_tool_sanitize_request_guardrail

> Register a scope-local tool request sanitization guardrail.

Generated from `cargo doc --no-deps -p nemo-relay -p nemo-relay-adaptive -p nemo-relay-ffi`.

<pre />

Register a scope-local tool request sanitization guardrail.

## Parameters

* `scope_uuid`: UUID of the target scope (null-terminated C string).
* `name`: Unique guardrail name.
* `priority`: Execution priority (lower runs first).
* `cb`: Sanitize callback.
* `user_data`: Opaque pointer passed to `cb`.
* `free_fn`: Optional destructor for `user_data`.

## Safety

`scope_uuid` and `name` must be valid C strings. `cb` must be a valid function pointer.
