Iron Law

NO AGENT DISPATCH WITHOUT A COMMITTED PLAN FILE IN docs/plans/ — agents without a written plan produce unreviewed, unverifiable output

Subagent-Driven Development (SDD)

Turns an approved plan into working, reviewed code using a 3-role pipeline: Implementer → Spec Reviewer → Quality Reviewer.

Works in two dispatch modes: subagent (Agent tool, sequential) and team (TeamCreate, concurrent).

When to Use

Prerequisites — both must be true:

• A plan file exists at docs/plans/YYYY-MM-DD-<feature>.md (created via /plan-review)
• The plan has 3 or more distinct implementation tasks
