/**
|
||||
* Unit tests for MCP prompts: token_auth_notice, trip-summary, packing-list, budget-overview.
|
||||
*
|
||||
* Note: MCP prompt arguments must be Record<string, string> per protocol spec.
|
||||
* The prompts.ts argsSchema uses z.number() for tripId, which is incompatible
|
||||
* with the MCP client's type-safe getPrompt. We therefore test prompt callbacks
|
||||
* directly via the registered prompt handlers on the server instance.
