No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
46/46 tools missing one or more hints — clio_log_time (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); clio_log_expense (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); clio_find_activities (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +43 more. OpenAI's directory rejects tools where any of the four hints are 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.
