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
83/83 tools missing one or more hints — show_config (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); my_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_projects (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +80 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
2 tools perform destructive updates without destructiveHint — delete_file deletes at line 904 (target.unlink()); edit_soul deletes at line 2770 (provenance_path.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 — edit_soul (line 2770: provenance_path.unlink(missing_ok=True))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named 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
12 files are minified or bundled, which is usually build output rather than concealment
Ship unminified, readable source.
Secrets stay with their owner
3 secrets sent to a request target we could not resolve (A2A_AUTH_TOKEN → dynamic, OPENAI_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.
Secrets not logged
2 secret values sent to print
Redact or omit secret values from log output.
Tool description accuracy
edit_soul: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
