RPC & ACP

Protocol modes adapt the same session lifecycle and capability registry used by the interactive terminal.

NDJSON RPC

$ jeden rpc

RPC serves newline-delimited JSON requests and events over standard input and output. Keep diagnostic logging off the protocol stream.

Agent Client Protocol

$ jeden acp

ACP exposes the runtime through the Agent Client Protocol on standard I/O for compatible editors and hosts.

Shared invariants

• Requests use the same workspace and policy gates as local sessions.
• Capabilities come from the active registry generation.
• Tool calls, approvals, usage, artifacts, and terminal outcomes are durable session events.
• Cancellation and deadlines are operation-scoped.
