What
The in-REPL haiku, opus, sonnet and fable sampling helpers emit their start progress event before validating arguments, so bad input shows up as a visible error rather than a throw with nothing recorded.
Details
"prompt must be a string" and "schema must be an object" now arrive as a repl_tool_call progress event with phase "error"
a non-string prompt is recorded in progress as an assembled placeholder naming its typeof
Evidence
schema must be JSON-serializable
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
