What problem does it solve? Plans for developer-facing products (APIs, CLIs, SDKs, libraries, docs) often ship with onboarding friction, weak error messages, and missing upgrade paths that silently kill adoption. This Skill audits a plan against proven developer experience standards before implementation begins. ## Core Features & Use Cases - Eight scored DX passes: Evaluates getting started, API/CLI/SDK design, error messages, documentation, upgrade paths, dev environment, community, and DX measurement, each rated 0-10. - Three review modes: DX EXPANSION for competitive advantage, DX POLISH for hardening every touchpoint, and DX TRIAGE for critical gaps only. - Persona-driven analysis: Builds developer personas, competitive benchmarks, magical moment specs, journey maps, and friction traces before scoring. - Outside voice check: Runs an independent cross-model review (Codex CLI or a Claude subagent) and surfaces cross-model disagreements for user decision. - Use Case: Before building a new public SDK, run a DX review on the plan to catch a 15-minute time-to-hello-world, undocumented breaking changes, and error messages that lack fixes, then walk through each finding interactively. ## Quick Start Ask the agent to run a DX review on my developer-facing product plan and score each dimension.
