elephant-goldfish-model vs hyperresearch

elephant-goldfish-model: Elephant-Goldfish Model (EGM) is a Google plugin of skills for drafting design specs with a context-rich agent and stress-testing them with fresh zero-context subagents before any code is written. It installs into Antigravity, Claude Code and Codex, and walks through brainstorm, draft and review steps while you approve the trade-offs.; hyperresearch: Hyperresearch is a deep research harness installed into Claude Code or OpenAI Codex, running a tier-adaptive 16-step pipeline that turns one prompt into an adversarially audited report with full source provenance. Every source it reads is stored in a searchable markdown-plus-SQLite vault that later sessions reuse.
