description: External-adapter sub-skill; a governed subprocess adapter that echoes its inputs.

---

A minimal external adapter (`runx.external_adapter.v1`). The runtime resolves the

- manifest, spawns the declared subprocess under the governed sandbox, hands it the

- invocation over stdio, and seals the adapter's reported result. Run it as a step

- in a graph (the external-adapter source is a graph-step front, not a top-level

+ manifest, spawns the declared trusted host subprocess, delivers its resolved

+ grant, hands it the invocation over stdio, and seals the adapter's reported

+ result. The process is not an OS confinement boundary. Run it as a step in a

+ graph (the external-adapter source is a graph-step front, not a top-level

runner).
