First point of contact for all substantial code work — routes to the right sub-protocol and supplies the shared discipline. Use whenever the task says "implement", "build", "add", "fix", "debug", "why does this happen", "review", "verify", "check this agent's work", "write a brief", "spec this for delegation", or "hand over / wrap up the session" — and whenever a code change spans more than one file or layer, even if it looks simple. For non-code work (design, art, writing, strategy, general problem solving) use the sibling skill wide-lens instead.
