Run and monitor
How to run a workflow, watch it execute, pause and resume, stop a runaway, and recover from a crash.
Running a workflow Three ways: Click the Run button in the top-right of the canvas. Press Ctrl/Cmd+R . Click an individual agent's play icon to run just that agent (sandbox mode: runs in isolation). When you click Run, Cerevisor opens the Execution Modal showing a pre-run summary: Total agents. Wave count. Estimated cost (per provider). Permissions the run will need. Skill availability check (preflight). If anything's wrong, missing provider, gated feature, incompatible skill: the modal blocks the run with an actionable error. If everything checks out, click Run in the modal to start. Click Cancel to dismiss. The Execution Modal Once a run starts, the modal shows live status. Top section: overall progress and run cost. Below that: one card per agent, grouped by wave. Each card shows: Status badge: Waiting / Running / Completed / Failed / Skipped . Streaming output preview (the agent's response as it's generated). Tool calls in flight, with the tool name and arguments. Wall-clock time so far. The agent's resolved provider + model. Click any agent card to expand it for full output and full tool-call history. The modal also shows: Current wave indicator at the top. Run cost so far (per provider). Permission prompts as banner toasts when an agent needs your sign-off. Stop, pause, resume Three buttons in the modal: Button Behavior Stop Hard stop. All running agents are cancelled; the run ends. Use for true emergencies. Pause After each agent's current tool call finishes, the orchestrator pauses. Resume picks up where you left off. Resume Continue from a paused state. The Execution Modal can be closed with Escape: the run continues in the background. To reopen, click the status indicator in the status bar. Permission prompts When an agent calls a destructive tool (typically bash , write_file , edit_file ), the Permission Modal opens. Options: Button Scope Allow once This single call. Allow always for this run Every call of this tool for the rest of the run. Allow always for this tool Permanently — writes to WorkflowPermissions . Deny Returns an error to the agent. Permission prompts pause only the agent that asked, other agents in the same wave continue running. Approval gates If a connection has flow type Approval Gate , the workflow pauses when it reaches the gate. The Approval Gate Modal shows: The upstream agent's output preview. The approval prompt you wrote on the connection. The downstream agent that's waiting. Click Approve to proceed or Reject to halt the run. Ask-user prompts If an agent calls the ask_user tool, the User Question Modal opens. It shows the question and either a list of choice buttons or a free-form text input. The agent pauses until you respond. Other agents (in the same or other waves) continue running. Run cost The status bar shows running cost. The Execution Modal breaks it down per provider, per agent. Costs come from the provider's reported usage: Anthropic: reported tokens × per-model pricing. OpenAI-compatible: reported
