All four hints declared on every tool

12/12 tools missing one or more hints — register_ucp_profile (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_ucp_profile (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); shopping_product_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any hint is missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
