Developer handoff

Run only on an explicit handoff, transfer or prepare-a-brief request. Document the agreed concept, not a production implementation package. Do not invoke this skill automatically after building a prototype.

Required reads

Read the complete handoff template and shared context resolution before drafting. Install product-design alongside this skill for that shared reference. If either installed file is missing, name its exact path and stop. Do not auto-install dependencies or invoke product-design to redesign the concept.

Use the shared resolver's first-existing-root selection, precedence, owner links and evidence rules. Read available relevant PRODUCT-DESIGN.md, DESIGN-SYSTEM.md, REPOSITORY.md, SEED-DATA.md and BROWSER-VALIDATION.md directly in that root. No manifest or handoff-specific context file is required. Never use drafts as approved context or copy shared policy into the handoff.
