sac and orochi

scitex-agent-container (sac) and scitex-orochi are two separate packages with a one-way dependency: orochi reads from sac; sac never imports orochi.

Responsibility split

Concern	Owner
Agent process (SDK + session.jsonl)	sac
Per-host control plane (start/stop/send/tail/list)	sac
Container runtime (apptainer)	sac
Cross-host message routing	orochi
Human chatops UI (Slack-like web interface)	orochi
In-session push (MCP channel server)	orochi ships MCP; sac runs the agent
SSH mesh / tunnel layer (cloudflared + autossh)	orochi
Peer registry	orochi (`~/.scitex/orochi/peers.yaml`)

Rule: sac knows containers + sessions on one host; orochi knows messages + people across hosts.

How orochi consumes sac

orochi reads ~/.scitex/agent-container/runtime/<name>/heartbeat.json and session.jsonl from each host it manages. It never calls sac CLI commands directly — the contract is the on-disk state files.

Agents push heartbeats and alerts to orochi via the server:orochi-push MCP channel, configured in spec.claude.channels:

spec:
  claude:
    channels:
      - server:orochi-push

Standalone use

sac works fully without orochi. If you don’t need cross-host chatops, just omit server:orochi-push from spec.claude.channels and skip the orochi install entirely.
