Definition
JSON reliability combines syntax validity, required-key coverage, stable value formatting, and honest missing-field handling. It is stricter than simply returning something that looks like JSON.
AI Agent term
JSON Reliability
The ability to return valid, complete, and schema-aligned JSON across repeated runs.
Why it matters
Automation pipelines fail when structured outputs are inconsistent. Reliable JSON is essential for routing, extraction, CRM updates, and downstream workflow tools.
Example
A purchase-order extraction agent returns the same required keys with valid dates and nulls for missing values.
