SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Documentation and onboarding flows often look fine on paper but fail in practice. This Skill actually tests the developer experience hands-on instead of guessing, producing an evidence-backed DX scorecard. ## Core Features & Use Cases - Live DX Testing: Navigates docs, runs the getting-started flow, and times time-to-hello-world (TTHW) using a browser tool. - Evidence Capture: Screenshots error messages and evaluates CLI help text to document real friction points. - Plan-vs-Reality Comparison: Compares measured results against /plan-devex-review scores (the boomerang: plan said 3 minutes, reality says 8). - Use Case: After shipping a new CLI or developer-facing feature, run a DX audit to verify a new user can actually get started, and get a scored report showing where they get stuck. ## Quick Start Ask the agent to run a live DX audit of the project's onboarding flow and produce a scorecard with TTHW measurements.

Frequently Asked Questions about devex-review

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I audit developer experience for my project?▼

Run a live DX audit that navigates your docs, attempts the getting-started flow, and times how long onboarding takes. The result is a scorecard with screenshots and evidence rather than subjective impressions.

How to measure time to hello world for onboarding?▼

Time-to-hello-world (TTHW) is measured by actually executing the getting-started flow from a fresh state and recording elapsed time. This skill automates that measurement and compares it against any previously planned estimate.

What is the difference between plan-devex-review and devex-review?▼

plan-devex-review produces predicted DX scores before shipping, while devex-review tests the real experience after shipping. Comparing the two reveals the gap between planned and actual onboarding time.

When should I run a developer experience audit?▼

Run it after shipping any developer-facing feature such as a CLI, SDK, or new documentation. It is also useful before launches to catch onboarding friction that internal testing missed.

Does the DX audit work in headless or CI environments?▼

The skill detects session kind (interactive, spawned, or headless) via its preamble and adapts behavior accordingly. In headless runs it blocks on interactive questions rather than prompting a nonexistent user.
