What problem does it solve? Developer experience claims are rarely verified against reality. This Skill actually tests the developer journey — navigating documentation, running the getting-started flow, timing time-to-hello-world (TTHW), and screenshotting errors — so teams get measured evidence instead of assumptions about onboarding quality. ## Core Features & Use Cases - Live DX Audit: Uses the browse tool to walk the real onboarding path, evaluate CLI help text, and capture screenshots of error messages. - TTHW Measurement: Times how long it takes a new developer to reach a working result and scores the experience. - Plan-vs-Reality Comparison: Compares live results against /plan-devex-review scores (e.g., plan said 3 minutes, reality says 8). - Use Case: After shipping a developer-facing feature or CLI, run a DX audit to verify the getting-started flow works end-to-end and produce a scorecard with evidence for the team. ## Quick Start Ask the agent to run a live DX audit of your project's onboarding flow and produce a scorecard with TTHW timing and screenshots.
