What problem does it solve? Developer onboarding quality is usually judged by intuition rather than evidence. This Skill performs a live developer experience audit: it actually walks through your documentation, getting-started flow, and CLI help text like a new user would, measures time-to-hello-world (TTHW), captures screenshots of errors, and produces a scored DX report with evidence. ## Core Features & Use Cases - Live DX Testing: Uses a browse tool to navigate docs, attempt the getting-started flow, and evaluate CLI help output as a real developer would. - Evidence-Based Scorecard: Times TTHW, screenshots error messages, and produces a DX scorecard backed by concrete artifacts rather than opinions. - Plan-vs-Reality Comparison: Compares results against prior /plan-devex-review scores (the boomerang: plan said 3 minutes, reality says 8). - Use Case: After shipping a developer-facing feature or SDK, ask for a DX audit to discover that the README's install command fails on a clean machine before your users do. ## Quick Start Ask the assistant to run a DX audit that tests the onboarding flow and times how long it takes a new developer to reach hello world.
