Spec Plan

Write a proportional plan so clear that any engineer can follow it. The selected planning mode determines whether the plan stays in the conversation or becomes a persisted structured artifact. This skill does not write code or start implementation.

atelier-orchestrator owns automatic classification and the human may override it. When this skill is directly invoked without a selected mode, use Spec-backed Plan. If Inline planning reveals substantial design or coordination needs, ask the human whether to switch to a Spec-backed Plan before presenting the plan.

Terminal boundary

This skill produces exactly one plan output and then stops:

• Inline mode presents the plan in conversation and changes no repository files.
• Spec-backed mode creates or updates only plan.json from an approved design.md.
