Create ExecPlan

Create a two-artifact plan package that turns validated context into an executable, update-in-place implementation plan.

• Use this when planning must be deterministic and auditable.
• Use this when implementation will be delegated to a low-reasoning executor that needs explicit, unambiguous steps.
• Use this when the plan must include context discovery output (greenfield or brownfield) and then drive tracked execution as a living document.

Workflow

Use this section for step context only. Use each step reference for detailed execution. Treat the directory containing SKILL.md as the skill root for bundled workflow resources (scripts/, references/, templates/). Resolve artifact output paths from the caller project root instead.

python3 scripts/scaffold_execplan.py --artifact-root ".plan/create-execplan/<timestamp>"
