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

32/32 tools missing one or more hints — get_kimchi_premium (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_exchange_fees (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); compare_exchange_prices (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +29 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.

Tool handlers catch errors

Only 11/32 tool handlers wrap calls in try/catch (34%)

Wrap each tool handler body in try/catch and return a structured error response.

Tool test coverage

Only 2/32 tools referenced in tests (6%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

8 child_process calls — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Domain consistency

npm scope @crossfin doesn't match GitHub owner bubilife1202

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