Architecture plan

Derive an actionable, incremental implementation/refactoring plan from an approved design, with review findings as supporting context when present. The artifact is executable by an engineer, mutator agent, or task runner; the architect writes the plan and stops.

When to use

Use after an architecture design, when the user wants approved target architecture implemented. For existing-code remediation, the default chain is architecture-review → architecture-design → architecture-plan. Plan one hotspot, boundary, module, or flow per plan unless a roadmap is explicitly requested.

If there is no approved design artifact, recommend architecture-design first. If there is no review report for existing-code remediation, recommend architecture-review before design unless the user explicitly wants greenfield target-state design.
