The Python deepagent process starts inside OpenShell, and every subprocess it spawns inherits the sandbox boundary. + +If your local OpenShell CLI uses a slightly different subcommand shape, treat [launch_in_openshell.sh](/Users/namrataghadi/code/agentcontrol/agent-control/examples/openshell_incident_responder/launch_in_openshell.sh) as the place to adapt the final command while keeping the rest of the demo unchanged. + +## Demo flow + +1. Phase 1 begins with a short preflight step that intentionally triggers an Agent Control `steer` for unpinned semgrep installation. +2. The autonomous agent then inspects the failing CI log and PR context with `deepagents` file tools. +3. Agent Control denies secret access, `curl | bash`, generic package installs, and out-of-workspace file reads if the agent attempts them. +4. A short deterministic validation phase summarizes the hostile runbook and reuses the approved internal handoff path. +5. OpenShell remains the outer safety boundary for unapproved binaries and hosts. +6. A deterministic walkthrough phase then forces one `steer`, two different `deny` cases, and one `block` so the security layers are visible every time. + +## Output legend + +The script now prints explicit layer ownership in the logs: + +- `[security][L1 Runtime Boundary]`: OpenShell policy decided the outcome +- `[security][L2 Semantic Policy]`: Agent Control decided the outcome +- `[security][L3 Approved Workflow]`: an approved business handoff path was used +- `[tool]`: the agent attempted or executed a tool action + +The leadership-friendly part is the deterministic guardrail walkthrough at the end: + +- `Scenario A: AgentControl steer` +- `Scenario B: AgentControl deny` +- `Scenario C: AgentControl deny destructive command` +- `Scenario D: OpenShell block` + +That makes it obvious where semantic policy ends and where runtime sandbox policy begins. + +To keep the demo fast, only the first investigation phase is open-ended. It is also wrapped in a timeout via `DEMO_PHASE_TIMEOUT_SECONDS` and defaults to 45 seconds. + +## Leadership takeaway + +This example demonstrates why the two layers matter together: + +- OpenShell answers "can this process reach this binary, path, or host at all?" +- Agent Control answers "should this specific command, with this intent and these arguments, be allowed?" + +That is the compelling operating model for daily autonomous work: keep the agent productive for normal CI triage, but constrain both infrastructure reach and semantic intent before the agent can turn a hostile repo
