EGM guides developers from brainstorming a feature through drafting a design, independent review by agents that don't see the drafting conversation, resolving findings, and checking for drift between design and code. It ships as a Claude Code plugin with commands such as /egm:egm-brainstorm, /egm:egm-draft, /egm:egm-review and /egm:egm-drift-report, and also works with Codex and Antigravity; the project is built at Google but not officially supported by it.", "body_md": "I’ve been working with a small group at Google on [Elephant-Goldfish Model](https://egm.dev), an open-source workflow for building software with AI agents. Thousands of Googlers already use it.\n\nYou can start with a feature you want to build. EGM helps you talk it through, write a design, get independent reviews, and work through the findings. As you build, you can check where the code has drifted from the design.\n\nThe agent helping you draft keeps your project context. Separate reviewers read the design and relevant code without seeing that conversation. They look for missing decisions and assumptions. You choose what to change.\n\nIn Claude Code, install the plugin:\n\n```\nclaude plugin marketplace add google/elephant-goldfish-model\nclaude plugin install egm@egm\n```\n\nRun `/egm:egm-brainstorm` with a feature you’re considering, then `/egm:egm-draft` to turn it into a design. When you have a draft, run `/egm:egm-review docs/designs/my-feature.md`.\n\nSome findings will be wrong. Check them against your intent and the code, then use `/egm:egm-resolve` to work through the ones that matter. `/egm:egm-drift-report` checks for differences between your design and implementation as things change.\n\nIt also works with Codex and Antigravity. See [egm.dev](https://egm.dev) for setup instructions. The plugin is Apache-2.0 licensed. Your usual coding-agent usage costs apply.\n\nTry it on a feature with a few real decisions to make and let me know how it goes in the comments.\n\n(Built at Google, not officially supported by Google.)", "url": "https://wpnews.pro/news/elephant-goldfish-model-from-idea-to-code-with-ai-agents", "canonical_source": "https://dev.to/olivernewth/elephant-goldfish-model-from-idea-to-code-with-ai-agents-105h", "published_at": "2026-10-27 04:06:36+00:00", "updated_at": "2026-10-27 04:13:39.438053+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "developer-tools", "generative-ai"], "entities": ["Google", "Elephant-Goldfish Model", "Claude Code", "Codex", "Antigravity"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/elephant-goldfish-model-from-idea-to-code-with-ai-agents", "markdown": "https://wpnews.pro/news/elephant-goldfish-model-from-idea-to-code-with-ai-agents.md", "text": "https://wpnews.pro/news/elephant-goldfish-model-from-idea-to-code-with-ai-agents.txt", "jsonld": "https://wpnews.pro/news/elephant-goldfish-model-from-idea-to-code-with-ai-agents.jsonld"}}
