The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Tool 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
8/8 tools missing one or more hints — list_categories (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_post (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_recent_posts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 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.
Descriptions match behaviour
2 tools describe read intent but their handlers mutate — get_recent_posts (line 226: /[?&]p=(\d+)/.exec(item.guid)); get_big_deals (line 226: /[?&]p=(\d+)/.exec(item.guid))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
