All four hints declared on every tool

8/9 tools missing one or more hints — sf_check (missing: destructiveHint, idempotentHint); crawl_site (missing: idempotentHint); crawl_status (missing: destructiveHint, idempotentHint), +5 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 annotations match behaviour

2 read-only tools perform write/delete/exec — sf_check (line 301: result = subprocess.run(); list_crawls (line 597: result = subprocess.run()

Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — list_crawls (line 597: result = subprocess.run()

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

6/9 tool handlers declare input schemas (67%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

8/9 tool handlers wrap calls in try/catch (89%)

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

Tests exist

No test files found

Add tests that exercise each declared tool.

Tool description accuracy

list_crawls: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
