A dependency guardrail that validates packages before your AI agent installs them. It searches 6,500+ curated developer tools with real compatibility data scraped from 4,500+ GitHub repos, so you can ask "find an auth solution for Next.js" or "check if these two tools work together" and get install commands, health scores, and verified stack combinations. The 23 tools include package validation to catch hallucinations and typosquats, compatibility search with conflict warnings, project scanning for recommendations, and market gap analysis showing what developers search for but can't find. Runs via uvx with zero installation. Useful when your agent wants to add dependencies or when you're architecting features and need to know what already exists in the indie ecosystem.
