prototype-feature

What problem does it solve?

Prototype-feature turns an approved OpenSpec proposal into multiple competing working skeletons, then drives a structured convergence using lightweight validation and human selection instead of expensive full implementations.

Core Features & Use Cases

• Parallel variant dispatch: Runs N angle-steered variant agents (default 3) against the approved proposal using isolated worktrees and branches to prevent cross-contamination.
• Cheap multi-phase scoring: Applies existing validation phases (smoke + spec) to each skeleton and records outcomes as data, not hard-fail exceptions.
• Human pick-and-choose feedback: Lets operators select per-aspect winners (data model, API, tests, layout) so iteration can synthesize a best-combination plan.
• Convergence handoff artifact: Writes a single prototype-findings.md file containing human picks plus per-variant machine-readable JSON for /iterate-on-plan.

Quick Start

Invoke the skill for an approved change id by running prototype-feature with the operator-approved change-id, optionally overriding angles and variant count to generate competing skeletons and produce prototype-findings.md for convergence.
