Guide for implementing Obsidian knowledge management - vault operations, plugin development, URI scheme automation, markdown extensions, and Local REST API integration. Use when working with Obsidian vaults, creating plugins, automating note workflows, querying notes via API, or implementing knowledge graph features.

Helps turn app ideas into shippable MVPs with opinionated guidance on scoping, tech stack (Next.js, Supabase, Vercel), and avoiding feature creep. Use when the user wants to plan an MVP, create a PRD, generate Claude Code prompts, scope features, make product decisions, or needs help staying focused on shipping. Triggers include "plan this app", "help me scope this", "create a PRD", "what should I build first", "generate a Claude Code prompt", or any request to turn an idea into something shippable.
