3/37 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
37/37 tools missing one or more hints — list_api_nodes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); apps (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); batch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +34 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
1 tool describes read intent but its handler mutates — report_issue (line 446: new RegExp()
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
Only 9/37 tool handlers declare input schemas (24%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Shell command execution
23 child_process/subprocess calls in production code — runs shell commands (src/orchestrator/index.ts:544, src/orchestrator/index.ts:607, src/orchestrator/index.ts:612)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets stay with their owner
2 secret/sensitive values flow into network calls (OPENAI_API_KEY → dynamic, ARENA_API_KEY → dynamic) (1 other flows matched canonical API hosts)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
