CODERABBIT_API_TOKENGITHUB_PERSONAL_ACCESS_TOKENNOTION_API_TOKENSLACK_BOT_TOKENSST_LIVETool 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
18/18 tools missing one or more hints — Generate-CodeRabbit-Report (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_repositories (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_file_contents (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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.
Tool inputs are validated
Only 0/5 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
3/5 tool handlers wrap calls in try/catch (60%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets stay with their owner
1 secret/sensitive value flow into network calls (NOTION_API_TOKEN → 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.
