OpenAI: Honest Tool Annotations Mean Less Screening and Faster MCP Calls
bibryam · x · 2026-10-23
From bibryam's keynote takeaways (13/16): accurate tool annotations matter. OpenAI's slide links verified read-only tools to less screening and faster calls; 61% of tools declare read-only, 21% open-world, 17% destructive. Describe side effects honestly—an annotation is a claim about behavior, not a substitute for checking it—and note that annotations are required for public apps.
