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
13/13 tools missing one or more hints — check_environment (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); setup_netease_login (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_song (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +10 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
3 tools perform destructive updates without destructiveHint — stop deletes at line 141 (fs.unlink(statePath)); shutdown deletes at line 141 (fs.unlink(statePath)); open_web_player deletes at line 141 (fs.unlink(statePath))
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 — play_song (line 136: fs.writeFile(statePath, JSON.stringify(state, null, 2), "utf8"))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
7/13 tool handlers declare input schemas (54%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Tool description accuracy
play_song: description implies read-only but handler writes/deletes/executes; open_web_player: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
