Lilarch

Use this skill for contained feature work that is too small for the full arch flow but still benefits from a real doc-backed plan.

When to use

• The change is a small feature or improvement.
• The work should fit in 1-3 phases.
• The user wants the "little arch" workflow rather than the full arch plan.

When not to use

• The task is a migration, a broad refactor, or clearly larger than 3 phases.
• The user wants a compressed one-pass arch plan instead of a start/plan/finish flow. Use arch-mini-plan.
• Investigation dominates because the root cause is unknown. Use bugs-flow or north-star-investigation.
