## 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.

## Output Template

```markdown
## Goal

## Phase Plan
1. Phase 1 - ...
2. Phase 2 - ...

## Task Breakdown

## Critical Files

## Notes

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