🔐
You'll be asked for 5 credentials: ENCRYPTION_KEY, LF_ADMIN_PASSWORD, LF_API_KEY, LF_JWT_SECRET, LF_WEBHOOK_SECRET
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

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

24/24 tools missing one or more hints — libreflow_list_node_types (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); libreflow_list_workflows (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); libreflow_get_workflow (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +21 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.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tool test coverage

18/24 tools referenced in tests (75%)

Write tests that reference each tool by name so every tool has at least one test.
