Module validation 

Tool argument validation: coerce what models commonly get wrong, then check the JSON schema with TypeBox’s error messages.

Port of packages/ai/src/utils/validation.ts in pi v1.0.0. The checker covers the JSON Schema keywords tool schemas use. $ref, format and pattern are accepted without checking.

Functions

validate_tool_arguments

Validated, coerced arguments for call, or the error pi reports to the model.
