What problem does it solve? Maintainers often cannot see the friction their own library or tool creates for new users — broken quickstarts, unstructured errors, missing machine-readable output, and unclear onboarding go unnoticed until support costs rise. This Skill audits a repository's developer experience across up to four surfaces and produces a scored, evidence-backed remediation plan. ## Core Features & Use Cases - Four-surface audit: Detects and audits CLI, programmatic library/API, server/service, and GitHub Action surfaces using prioritized P0/P1/P2 checklists. - Deterministic scoring: Scores each check 0/1/3/5 (with na renormalization) and rolls up category, surface, and overall scores via a dependency-free Node scorer. - Two audit tiers: A static tier for docs/source inspection and a fixture tier that runs clean-room consumer installs for real TTFS, success-rate, and example-reliability metrics. - Use Case: Run /dx-audit in a repo you maintain to get a report.md, scorecard.json, and prioritized remediation plan written to a temp directory, with quick wins ranked by impact and effort. ## Quick Start Ask the agent to run a DX audit on the current repository, for example by saying "audit the developer experience of this repo across all detected surfaces and give me the scored report."
