@open-pencil/harness
Private Node runtime for coding-agent harness sessions. It owns the backend-neutral session lifecycle, opaque resume-state persistence, and the JSONL sidecar protocol used by host applications.
The first backend uses AI SDK HarnessAgent, Pi, and local just-bash. Pi runs in the Node host process; just-bash provides an isolated in-memory workspace and shell without requiring cloud infrastructure.
Current scope
- Backend-neutral, streaming session service.
- Atomic, bounded persistence of opaque harness resume state.
- JSONL stdio sidecar transport.
- Pi +
just-bashbackend.
The package is not wired into the desktop application yet. Credentials are supplied to the sidecar process at runtime and are never written to resume-state storage.
Local sandbox limitation
just-bash is process-local and in-memory. Multi-turn sessions work while the sidecar remains alive, but its sandbox cannot be reattached after a process restart. Persisted opaque state establishes the session contract; durable restart recovery requires a persistent sandbox provider in a later integration.
