 ## Rules
 
+- For interrupted runs, call `wf run inspect <run_id>` before resuming. If the
+  interrupt includes `resume_schema`, shape `wf run resume --payload` to that
+  schema instead of guessing field names.
 - Use explicit `--config <path>` for examples, challenge workspaces, and
   non-root configs. The default is `wf.config.json` in the current working
   directory.

+## Interrupt Resume Contracts
+
+An interrupted run can carry a self-describing resume contract. Treat
+`interrupt.resume_schema` from `wf run inspect` as the source of truth for the
+payload you pass to `wf run resume`. Do not read workflow source code just to
+guess approval fields when the schema is present.
