Create Plan

Hard rules

Plan only — never implement.
Allowed writes: .plans/<kebab-name>.md, and .reviews/*-decomplex.md when needed.
Evidence-backed. Smallest design. No speculative scope.
Ask user on material ambiguity (scope/behavior/architecture/migration/risk/complexity). No shaky assumptions.
Delegate by default for research and review when safe. “Small/easy” ≠ skip subagents.
Leverage subagents — built-in, extensions/plugins, or skills. Follow use-subagents policy; use native subagents, extensions / plugins, or other skills
Main agent owns synthesis, plan writes, dispositions, delivery.
Child/reviewer output = evidence, never acceptance. Findings never auto-enter the plan.
Prefer simpler fixes. Stuck review (2 failed rounds / recurrence / no progress) → ask user.

Before draft: read assets/implementation-plan-template.md.
Before finalize (and after material edits): read references/plan-quality-checklist.md.
Missing resources → stop. Don’t invent substitutes.
