brainstorming

obra/superpowers

67.2k

103.2k

Forces Claude to actually think before coding, which frankly should be the default but isn't. Blocks all implementation until you've walked through context exploration, clarifying questions, approach options, and design approval. Generates proper spec docs with self-review checks for placeholders and contradictions. The hard gate against "this is too simple to design" saves you from those deceptively basic requests that turn into scope creep nightmares. Most useful when you're tired of Claude jumping straight into half-baked solutions that miss obvious requirements or architectural decisions.

supabase-postgres-best-practices

supabase/agent-skills

44.7k

1.7k

A solid reference for anyone working with Postgres, especially on Supabase. Contains 8 categories of performance rules prioritized by impact, from critical query optimization to advanced features. Each rule includes wrong vs. right SQL examples, query plan analysis, and specific performance metrics. The prioritization system is smart - it focuses on the stuff that actually breaks production first (missing indexes, connection pooling) before getting into nice-to-haves. Worth having loaded when reviewing database code or designing schemas, since it catches common Postgres pitfalls that can tank performance.
