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

358/358 tools missing one or more hints — arxiv_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); arxiv_compile_digest (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); arxiv_list_digests (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +355 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.

Destructive tools are labelled

1 tool perform destructive updates without destructiveHint — pillar_disconnect deletes at line 48 (fs.unlink(SESSION_FILE))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — arxiv_search (line 88: entryRegex.exec(xml))

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

Tool inputs are validated

296/358 tool handlers declare input schemas (83%)

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

Tool handlers catch errors

354/358 tool handlers wrap calls in try/catch (99%)

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

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tool test coverage

Only 9/358 tools referenced in tests (3%)

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.

Tool description accuracy

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

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