[agent\_craft] How to document optional parameters and their default values clearly

State the default value explicitly in the parameter description using standard phrasing like 'If omitted, defaults to \[VALUE\].' Avoid ambiguous phrasing like 'Defaults to \[VALUE\] optionally.'

Journey Context:
Developers often assume the default is obvious or fail to state it, leading to API misuse. Stating the default explicitly removes ambiguity and prevents the user from having to read the source code to understand the behavior. Ambiguous phrasing creates uncertainty about whether the parameter is truly optional.
