XDG_STATE_HOMETool 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
61/61 tools missing one or more hints — pt_list_devices (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); pt_list_templates (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); pt_get_device_details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +58 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 inputs are validated
55/61 tool handlers declare input schemas (90%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 20/61 tool handlers wrap calls in try/catch (33%)
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.
No eval / new Function
1 eval() or new Function() call — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Readable source code
1 file appear obfuscated
Ship unminified, readable source.
