What problem does it solve? Developer experience is usually reviewed on paper, not tested in reality. This Skill runs a live DX audit: it navigates your docs, attempts the getting started flow, times time-to-hello-world (TTHW), screenshots error messages, and evaluates CLI help text, then produces an evidence-backed DX scorecard. ## Core Features & Use Cases - Live DX Testing: Uses a browse tool and bash to actually walk the onboarding flow instead of reading about it, capturing screenshots as evidence. - Eight-Dimension Scorecard: Scores Getting Started, API/CLI/SDK ergonomics, Error Messages, Documentation, Upgrade Path, Dev Environment, Community, and DX Measurement on a calibrated 0-10 rubric. - Boomerang Comparison: Compares live audit scores against prior /plan-devex-review plan-stage scores to flag where reality fell short of the plan. - Use Case: After shipping a developer-facing feature, run a DX audit to measure actual TTHW, catch confusing error messages, and verify docs search works before users bounce. ## Quick Start Ask the assistant to run a DX audit of your product's getting started flow and produce a scored report with evidence.
