grok-runtime skillA
grok-runtime is agent-read markdown (skill) from vasihemanth/grok-build-plugin: Internal helper contract for calling the grok-companion runtime from Claude Code or Codex. Reference when invoking the Grok companion script or the grok_search MCP tool..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Grok companion runtime
The Grok plugin wraps the local `grok` CLI's **headless mode** (`grok -p "<prompt>" --output-format json`). Grok manages its own session store under `~/.grok/sessions`, so the plugin does not run a separate server or broker.
Always invoke through the companion script so job tracking, prompt shaping, and tool filtering stay consistent:
```bash
node "${CLAUDE_PLUGIN_ROOT}/scripts/grok-companion.mjs" <subcommand> [flags] [text]
```
Or, for live search from any MCP-capable agent, call the `grok_search` tool (auto-wired when the plugin is installed; otherwise `npx -y grok-build-x-search-mcp`).
## When to use Grok (routing guidance for host agents)
| Need | Prefer |
| --- | --- |
| Live X sentiment, breaking news, "what are people saying" | `grok_search` / `/grok:search` |
| Current package/version/docs facts beyond training cutoff | `grok_search` / `/grok:search` |
| Second opinion code review on a diff | `/grok:review` |
| Substantial implement/debug pass with write access | `/grok:rescue` or `grok:grok-rescue` subagent |
| Trivial local edit the host can do in one step | **Do not** delegate — handle inline |

How to install
mdr add vasihemanth/grok-build-plugin/grok-runtime@git:20260711.00eb3c9mdr add vasihemanth/grok-build-plugin/grok-runtime@sha256:b4ce7a339d80d16bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
