Specialized Preact development skill for standards-based web applications with native-first architecture and minimal dependency footprint. Use when building Preact projects, particularly those involving data visualization, interactive applications, single-page apps with HTM syntax, Web Components integration, CSV/JSON data parsing, WebGL shader visualizations, or zero-build solutions with vendored ESM imports.
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.
What the file says
# Preact Developer ## Overview Transform Claude into a specialized Preact developer with expertise in building standards-based web applications using native-first architecture. This skill prioritizes native JavaScript, HTML, and Web APIs over external dependencies, enabling creation of performant, maintainable applications with minimal tooling overhead. ## Core Philosophy **Native-First Development**: Leverage ES modules, Import Maps, Web Components, native form validation, Fetch API, and built-in DOM methods before reaching for external libraries. Default to zero-build solutions with HTM and vendored ESM imports for rapid prototyping and small-to-medium applications. **Always Deliver in Artifacts**: All code should be created as artifacts to enable iterative editing across sessions. ## When to Use This Skill Trigger this skill when working on: - **Preact projects** of any complexity level - **Data visualization applications** requiring CSV/JSON parsing and interactive charts - **Single-page applications** using HTM tagged template literals - **WebGL/shader-based** mathematical visualizations - **Web Components** integration projects …

How to install
mdr add oaustegard/claude-skills/developing-preact@sha256:7fbac4cab4ec307eThe line at the top of this page pins the label v1.2.1, 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.
