Spellbook of Skill: The Twin Project Nobody Asked For, But I Built Anyway

A developer introduces Spellbook of Skill, an open source, MIT-licensed collection of practical development guides organized by category and difficulty, built as a companion to his earlier prompt-collection project Spellbook of Prompt. The site runs on Astro with Starlight and was built end-to-end using OpenCode wired through OpenRouter with DeepSeek V4 Pro, which the author frames as proof that a budget AI model stack can ship a complete project. Content is currently sparse, starting with a Content Creation category, with more planned, and the project is now soliciting community contributions via pull requests.
