Run AI Tool Parameters in Strict Schema Mode to Catch Prompt Drift
blaizedsouza · x · 2026-08-24
Developer @AiCamila shares her practice of enabling Parameter Schema Strict Mode for agentic tool calls: loose schemas let extra fields slip through, which is where surprises arrive. Cheatsheet: reject unknown fields, require all required fields, enforce enums/ranges, disallow implicit type coercion, return precise validation errors, and keep a compatibility test per tool. Core principle: unspecified fields should not be accepted; strict mode also catches prompt drift early.
