Schemas

Learn in five minutes

• A schema names the fields you will accept.
• Extra fields are a choice: reject them or ignore them, and write which.
• A schema does not make the values true.
• JSON is the usual carrier. RFC 8259 is the citation for the text format.
• Validate before you act on a tool argument.

A tool that receives {"city": "Paris"} when it required a number should refuse. The fluent explanation is not the action.

Schema

The declared shape of an output or a tool argument.

Sisters: JSON schema, Rubrics, Regression tests.

The same job-shape-test card works for chat, voice, and a tool result.

The capstone reuses this card.

Config

• Write the goal in one sentence.
• Name the input and the allowed output.
• Save the trace next to the result.

Troubleshooting

• The answer looks fluent and is wrong. Check whether a source passage actually contains the claim.
• The loop never stops. Set a step cap and stop when the tool result repeats.
