JSON schema scenarios — CCA-F Exam Prep

Three schemas. One is bulletproof. Two will break in production.

JSON schemas define the contract between systems. When Claude calls a tool, the input must match a schema. When Claude returns structured output, it must match a schema. When your API responds, it must match a schema.

The CCA-F tests whether you can design schemas that handle edge cases -- not just the happy path. Today you will design three schemas and stress-test them.
