What problem does it solve? Teams often jump from brainstorming straight into implementation planning without validating whether a feature is actually buildable, leading to wasted planning effort on blocked or premature work. This Skill inserts a lightweight feasibility gate that produces a clear verdict in under five minutes. ## Core Features & Use Cases - Single-agent feasibility assessment: Dispatches one Sonnet agent with the feature spec to answer four targeted questions about assumptions, dependencies, MVP scope, and verdict. - Structured decision output: Saves a standardized Markdown report with a GO, CONDITIONAL GO, or DEFER verdict to docs/superpowers/feasibility/. - Clear next-step routing: Each verdict maps to an explicit action, such as proceeding to writing-plans or resolving blocking dependencies first. - Use Case: After brainstorming a new API integration feature, run this gate to discover that a third-party OAuth permission is missing, yielding a DEFER verdict before any planning time is spent. ## Quick Start Run a feasibility check on the feature spec we just brainstormed and tell me whether to proceed to planning.
