Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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
77/77 tools missing one or more hints — memory_add (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memory_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); memory_list_all (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +74 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
9 tools perform destructive updates without destructiveHint — memory_add deletes at line 355 (os.remove(os.path.join(MEMORY_DIR, f"{stale['name']}.md"))); memory_delete deletes at line 490 (os.remove(os.path.join(MEMORY_DIR, f"{name}.md"))); memory_clear deletes at line 512 (os.remove(os.path.join(MEMORY_DIR, f"{e['name']}.md")))
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.
Shell command execution
1 call in production code run through a shell (mimir/vscode-extension/src/extension.ts:777)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
1 secret sent to a request target we could not resolve (VLLM_API_KEY → dynamic) — often a configured endpoint, not necessarily third-party
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
