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
427/427 tools missing one or more hints — mcp_start (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mcp_stop (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mcp_restart (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +424 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 — snapshot_delete deletes at line 506 (os.remove(path)); snapshot_compare_live deletes at line 617 (os.remove(path_live)); stamp_delete deletes at line 404 (os.remove(fp))
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
2 tools describe read intent but their handlers mutate — device_catalog_scan (line 662: with open(out_path, "w", encoding="utf-8") as f:); text_export_manifest (line 69: with open(out_path, "w", newline="", encoding="utf-8") as f:)
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool test coverage
221/427 tools referenced in tests (52%)
Write tests that reference each tool by name so every tool has at least one test.
Tool description accuracy
device_catalog_scan: description implies read-only but handler writes/deletes/executes; text_export_manifest: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
