An Agent Skill for Claude Code that makes the agent look outside before it builds. When you choose a library, look for a prior implementation, check what a paper or an official spec actually says, or are about to write custom code, the agent searches registries, code, papers and official docs, then writes a dated, sourced report. You (or the session that asked) pick from it: adopt a candidate (Adopt), adopt one piece of it (Adopt-part), or build what no candidate covers (Build).
