Compatibility: If AskUserQuestion is unavailable, present options as a numbered list and wait for the user's reply. If Task is unavailable, run parallel steps sequentially.

Critical Rules

• Never write code, modify files, or run build/test commands — this skill plans only; execution is for spec:go
• Never create source files — only plan files (plan.md, phase-N.md, user-guide.md) and research artifacts
• Never run the task runner commands you discover — record them for the execution agent, do not invoke them
• Never apply "quick fixes" while planning — if you spot a bug or improvement opportunity, note it in the plan as a task, do not touch it
• Stop at the plan — when the user says "looks good", your job is done; do not start implementing

Create a structured multi-phase implementation plan. The goal is a tight, well-scoped plan that an autonomous execution agent can follow without further guidance.
