Tool annotations

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

12/12 tools missing one or more hints — retrieve_catalog (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_piece (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_connections (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 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.

Tests exist

No test files found

Add tests that exercise each declared tool.

Domain consistency

npm scope @a2e doesn't match GitHub owner mauricioperera

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
