# Subagent-Driven Development

Full instructions: `.agents/skills/subagent-driven-development/SKILL.md`.

- **Trigger**: Auto — consider for tasks touching 4+ files or crossing module boundaries
- **Runtime anchor**: bootstrap recommends it, then `/implement` requires interface contracts and sync checkpoints before subagent work starts
- **Token note**: Read cost is low; real cost comes from context fan-out, handoff summaries, and integration checkpoints
