What problem does it solve? Validating whether an idea is technically feasible before committing to a full build is risky and unstructured. This Skill turns an idea into focused, verifiable experiments (spikes) that produce verified knowledge for the real build. ## Core Features & Use Cases - Idea Mode: Describe an idea and the Skill decomposes it into focused experiments, ordered by risk, with research and verification gates. - Frontier Mode: Run without arguments to analyze the existing spike landscape and propose integration and frontier spikes. - Wrap-Up Packaging: Use the --wrap-up flag to package spike findings into a persistent project skill for future build conversations. - Use Case: Before building a new real-time collaboration feature, spike the WebSocket sync approach to validate feasibility, then wrap up the findings so the actual build starts with verified knowledge. ## Quick Start Invoke $gsd-spike followed by a description of the idea you want to validate, or run it with no arguments to get frontier spike proposals.
