# HVE Builder Skill

## Goal

Deliver a usable prompt, instruction, agent, subagent, or skill that meets the requirements catalog, or a credible read-only report, with the fewest lifecycle turns that preserve an independent review pass and final-state evidence.

Read [references/workflow-contract.md](references/workflow-contract.md) first; it owns mode routing, candidate convergence, the review pass, and overall outcomes. Apply [references/requirements-catalog.md](references/requirements-catalog.md) as the quality standard. The References section maps the remaining on-demand references.
