What problem does it solve? Developer experience is often planned but never actually tested. This Skill runs a live DX audit in a real browser: 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: Actually walks the onboarding path in the Aside browser instead of reviewing docs on paper. - TTHW Measurement: Times how long a new developer takes to reach a working hello-world, with screenshots as evidence. - Plan-vs-Reality Boomerang: Compares measured results against /plan-devex-review scores (e.g. plan said 3 minutes, reality says 8). - Use Case: After shipping a new CLI or SDK, ask for a DX audit to verify the getting-started flow works end to end and to catch confusing error messages before users do. ## Quick Start Ask the assistant to run a live DX audit of the getting-started flow and produce a scorecard with TTHW timing and screenshots.
