Standing [Claude Code ultracode](https://code.claude.com/docs/en/workflows) for [Grok Build CLI](https://x.ai/news/grok-build-cli).

Grok already has the runtime: deterministic workflow scripts via the `workflow`

tool and `/workflows`

. This plugin is the missing `/effort ultracode`

layer — on every substantive task the agent authors a workflow and launches it, instead of orchestrating turn by turn.

Not affiliated with xAI or Anthropic. Claude Code already has this natively; do not install this plugin there.

Plugin (skill + `/ultracode`

):

```
grok plugin install malakhov-dmitrii/grok-ultracode --trust
```

Enable it in `/plugins`

if it stays off (Grok plugins start disabled). Then install the standing rule — plugins cannot write `~/.grok/rules/`

:

```
git clone https://github.com/malakhov-dmitrii/grok-ultracode.git
cd grok-ultracode
./scripts/install-rule.sh
```

No-plugin path (skill + rule into user dirs):

```
./scripts/install.sh
```

Requires a Grok Build that ships `~/.grok/bundled/skills/create-workflow/SKILL.md`

(the workflow dialect). Too-old builds will not run authored scripts.

New Grok session:

```
/ultracode
```

Reply should be `ULTRACODE ON`

. After that, bugfixes, reviews, migrations, and research become workflows. Watch `/workflows`

. Stop with `/ultracode off`

.

One-shot, no standing mode:

```
ultracode: audit src/routes for missing auth
```

or `use a workflow to …`

.

- Not a Grok harness patch. No native
`/effort ultracode`

flag exists; this is a skill + optional home rule. - Not
`ultrawork`

/`ralph`

. 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.

```
skills/ultracode/SKILL.md   # standing protocol + author/launch loop
rules/ultracode.md          # always-loaded opt-in pointer (copy to ~/.grok/rules)
plugin.json                 # Grok plugin manifest
.grok-plugin/               # marketplace index + manifest
```

Dialect and host API live in Grok Build itself (`create-workflow`

bundled skill). This repo does not vendor that file.
