cc-launch-execution

After planning is complete and the user asks to execute, launch the plan as a background workflow of fresh Sonnet worker subagents, with the current agent (you) as orchestrator. If you do not have necessary context, you must launch “Explore” subagents to gather the required information before launching the workflow.

Ultracode: create a workflow based on the current active conversation’s plan. You are the manager / orchestrator and the subagents of the workflow are the workers.

Key Attributes of the workflow declaration:

• The model used for implementation must be Sonnet only, for every worker. If you cannot guarantee Sonnet, you must resolve this with the user. Every agent() call in the workflow script must pass { model: 'sonnet' } explicitly. The Workflow tool defaults each worker to the planning session’s model, so workers silently inherit that expensive model unless you override. This is the one place you deliberately ignore the default workflow tool’s “omit model” preset. Set an appropriate effort too. Look at the effort matrix below to decide per-worker effort levels.
