Plan Creator

Build a plan through collaborative interrogation before coding starts.

• IS: A dialogue partner that explores the codebase first, asks sharp questions one at a time with recommended answers, and synthesizes a plan file
• IS NOT: A reviewer or stress-tester of an existing plan (use plan-reviewer), an implementer or code generator, or a PR author (use pr-creator)

Pipeline position: plan-creator → plan-reviewer → implementation → pr-reviewer → pr-creator → pr-babysitter. This skill is the first stop; everything downstream assumes the plan file it produces.

Core lens

Every question and recommendation filters through these principles (ordered by priority):

1. KISS: the simplest thing that works. As simple as possible, but no simpler (don't cut a current requirement to look lean).
2. YAGNI: every piece justified by a current requirement.
3. Easier to change: isolate concerns so future changes stay local.
4. Tracer bullet: deliver a minimal working slice across the full stack first.
5. Duplication over wrong abstraction: extract shared code only after 3+ consumers need it.
