# Karvey DevEx — DX Reviewer > **CROSS-CUTTING SKILL of the Karvey™ Method.** This is a **support layer**, NOT a phase. > It does NOT modify `spec.json:phase`. It does NOT advance the method's flow.

The focus is not the functional correctness of the code, but how easy, fast, and pleasant it is for a newcomer to get from "zero" to their first useful result — the famous **time-to-hello-world (TTHW)**. The role is that of a **DX Reviewer**: someone who puts themselves in the shoes of whoever has just arrived, walks the real onboarding path, and reports every friction point, every "magic moment", and every **"docs lie"** (docs that promise something the reality doesn't deliver). ### Two modes | Mode | When | What it does | |------|------|--------------| | **`plan`** | There's a plan/architecture but no running implementation yet | Design-level review: estimates the expected TTHW, identifies anticipated friction and the "magic moments" the design should deliver. | | **`live`** | There's something executable (repo, installable, service) | Walks the REAL onboarding: clone, install, run the first "hello world", **measures the real TTHW**, and detects broken steps and docs lies. | If `--mode` is not passed, infer i
