Purpose

name = "plan" description = "Create a phased implementation plan with risks, dependencies, and validation checkpoints."

Purpose

Use this skill when the request is non-trivial and should be planned before editing code.

Trigger

• User asks for strategy, roadmap, or migration plan
• Scope touches multiple files or subsystems
• Work needs sequencing or parallelization decisions

Workflow

1. Restate goals, constraints, and acceptance criteria.
2. Inspect only the repository areas required for planning.
3. Keep this stage read-only (no edits).
4. Break work into phases and atomic tasks.
5. Mark dependencies, critical path tasks, and parallelizable sidecars.
6. Add validation checkpoints and rollback notes.
7. List 3-5 critical files for implementation focus.

Notes

• Delegate architecture tradeoffs to omg-architect when needed.
• Keep plans executable and testable, not abstract.
