+# Planning Skill
+
+## When to use this skill
+- any multi-file change
+- any change that impacts behavior, data, auth, billing, or production workflows
+- any debugging that needs systematic isolation
+
+## Planning rules
+- Steps should be **small** (2–10 minutes each).
+- Every step must include **verification**.
+- Prefer **incremental deliverables** (avoid “big bang” edits).
+- Identify **rollback** and **risk controls** early.
