The plugin, installable via 'grok plugin install malakhov-dmitrii/grok-ultracode --trust', requires a Grok Build version that ships the create-workflow bundled skill and is not affiliated with xAI or Anthropic. It is not a native '/effort ultracode' flag but a skill plus optional home rule, with a default run cap of 24 agents.", "body_md": "Standing [Claude Code ultracode](https://code.claude.com/docs/en/workflows) for [Grok Build CLI](https://x.ai/news/grok-build-cli).\n\nGrok already has the runtime: deterministic workflow scripts via the `workflow`\n\ntool and `/workflows`\n\n. This plugin is the missing `/effort ultracode`\n\nlayer — on every substantive task the agent authors a workflow and launches it, instead of orchestrating turn by turn.\n\nNot affiliated with xAI or Anthropic. Claude Code already has this natively; do not install this plugin there.\n\nPlugin (skill + `/ultracode`\n\n):\n\n```\ngrok plugin install malakhov-dmitrii/grok-ultracode --trust\n```\n\nEnable it in `/plugins`\n\nif it stays off (Grok plugins start disabled). Then install the standing rule — plugins cannot write `~/.grok/rules/`\n\n:\n\n```\ngit clone https://github.com/malakhov-dmitrii/grok-ultracode.git\ncd grok-ultracode\n./scripts/install-rule.sh\n```\n\nNo-plugin path (skill + rule into user dirs):\n\n```\n./scripts/install.sh\n```\n\nRequires a Grok Build that ships `~/.grok/bundled/skills/create-workflow/SKILL.md`\n\n(the workflow dialect). Too-old builds will not run authored scripts.\n\nNew Grok session:\n\n```\n/ultracode\n```\n\nReply should be `ULTRACODE ON`\n\n. After that, bugfixes, reviews, migrations, and research become workflows. Watch `/workflows`\n\n. Stop with `/ultracode off`\n\n.\n\nOne-shot, no standing mode:\n\n```\nultracode: audit src/routes for missing auth\n```\n\nor `use a workflow to …`\n\n.\n\n- Not a Grok harness patch. No native\n`/effort ultracode`\n\nflag exists; this is a skill + optional home rule. - Not\n`ultrawork`\n\n/`ralph`\n\n. Those still use the model as orchestrator. Ultracode puts the loop in a script. - Not cheap. Default run cap is 24 agents (medium). Skip status questions and one-file answers; those stay in the conversation.\n\n```\nskills/ultracode/SKILL.md   # standing protocol + author/launch loop\nrules/ultracode.md          # always-loaded opt-in pointer (copy to ~/.grok/rules)\nplugin.json                 # Grok plugin manifest\n.grok-plugin/               # marketplace index + manifest\n```\n\nDialect and host API live in Grok Build itself (`create-workflow`\n\nbundled skill). This repo does not vendor that file.\n\nMIT", "url": "https://wpnews.pro/news/show-hn-grok-ultracode-standing-ultracode-for-grok-build-cli", "canonical_source": "https://github.com/malakhov-dmitrii/grok-ultracode", "published_at": "2026-08-21 08:50:48+00:00", "updated_at": "2026-08-21 09:14:07.191284+00:00", "lang": "en", "topics": ["developer-tools", "ai-agents", "ai-tools"], "entities": ["Dmitrii Malakhov", "Grok Build CLI", "Claude Code", "xAI", "Anthropic", "grok-ultracode"], "alternates": {"html": "https://wpnews.pro/news/show-hn-grok-ultracode-standing-ultracode-for-grok-build-cli", "markdown": "https://wpnews.pro/news/show-hn-grok-ultracode-standing-ultracode-for-grok-build-cli.md", "text": "https://wpnews.pro/news/show-hn-grok-ultracode-standing-ultracode-for-grok-build-cli.txt", "jsonld": "https://wpnews.pro/news/show-hn-grok-ultracode-standing-ultracode-for-grok-build-cli.jsonld"}}
