nothing-new-under-the-sun

Research-first scouting agent skill that runs BEFORE any build decision, new dependency, new system, or feature request. Search existing solutions (codebase, dependencies, packages, GitHub repos, APIs, SaaS, templates) before writing code. Output a REUSE / USE / FORK / BUY / INTEGRATE / BUILD recommendation with a required schema and evidence matrix. Uses five-component long-term business value framing. Trigger on new features, new systems, new dependencies, build-vs-buy decisions, or "build/add/we need X" requests. Do not trigger for bug fixes, small refactors, routine edits, docs, style/lint, or imports already in use.
