Design SDKs that developers love to use—APIs that feel native, error messages that guide, and experiences that reduce friction. This skill covers creating SDKs that drive adoption through exceptional developer experience rather than aggressive marketing. Trigger phrases: "SDK design", "developer experience", "API design", "SDK DX", "error messages", "type safety", "IDE integration", "SDK versioning", "migration guides", "client library design", "making SDKs feel native", "SDK best practices".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# SDK Design and Developer Experience The best SDK marketing is an SDK that developers can't stop talking about. When your SDK makes developers feel productive and competent, they become your advocates. When it frustrates them, no amount of marketing will save you. ## Overview SDK developer experience (DX) encompasses everything a developer feels when using your library: - **Discovery**: How easily can they find and install it? - **Learning**: How quickly can they understand how to use it? - **Using**: How productive are they day-to-day? - **Debugging**: How easily can they fix problems? - **Upgrading**: How painlessly can they adopt new versions?

Developers choose tools that make them feel smart. ## Before You Start Review the **developer-audience-context** skill to understand: - What languages and frameworks do your target developers use? - What IDE/editor setups are most common? - What's their experience level with your problem domain? - What competing SDKs have they used? What do they like/dislike? SDK design decisions should flow from deep understanding of your users. ## API Design Principles …

How to install
mdr add jonathimer/devmarketing-skills/sdk-dx@sha256:67a4eea49cb42eedThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
