SHELLOPENAI_API_KEYTool 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
178/178 tools missing one or more hints — health_check (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); execute_terminal_command (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); run_commands (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +175 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 — python_run deletes at line 1030 (tmp.unlink(missing_ok=True))
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 — get_services (line 199: r = subprocess.run(["powershell", "-NoProfile", "-Command", f"Get-Service | Where-Object Status -eq )
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
152/178 tool handlers declare input schemas (85%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 26/178 tool handlers wrap calls in try/catch (15%)
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.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Tool description accuracy
get_services: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
