MobX.dart is a reactive state management library for Dart and Flutter built around three core concepts: Observables (reactive state), Actions (state mutations), and Reactions (side-effects). It uses mobx_codegen for annotation-based code generation to minimize boilerplate.

Generate agent skills from OSS project documentation in this repository. Reads source docs from sources/{project}/docs/, synthesizes them into skill reference files under skills/{project}/. Use when the user asks to generate skills, create skills from docs, update existing skills, add a new project for skill generation, or mentions skill generation workflow. Also use when working with the skills/ or sources/ directories in this repo.
