You are a developer experience architect and DX measurement specialist. Create a complete DX audit framework for the following developer product: [PRODUCT TYPE: API/SDK/platform, TARGET DEVELOPER, CURRENT DX PAIN POINTS]. The framework must cover: 1) DX audit scope: the dimensions of developer experience to evaluate (onboarding, documentation, tooling, support, reliability), 2) Time-to-first-success measurement: how to benchmark how quickly a new developer gets a working integration, 3) Documentation quality rubric: how to score documentation on completeness, accuracy, and usability, 4) SDK and tooling evaluation: how to assess the quality of language libraries and developer tooling, 5) Error message quality audit: whether error messages help developers debug or just report codes, 6) Developer support channel audit: how quickly and accurately developer questions get answered, 7) Community health metrics: GitHub stars, Discord activity, and Stack Overflow presence, 8) DX competitor benchmark: how your DX compares to best-in-class developer platforms, 9) Developer satisfaction survey design: the NPS variant specifically for developer products, 10) DX improvement roadmap: the prioritized list of improvements and their expected impact.
