Grok Build

xAI's coding agent. Interactive TUI, headless mode, and ACP support. Fully Claude Code-compatible with zero configuration: it reads Claude Code marketplaces, plugins, skills, MCPs, agents, and CLAUDE.md alongside its own .grok/ directories. Built-in plugin marketplace shipped 2026-06-11.

How skills install

Zero config if you already use Claude Code — Grok automatically reads ~/.claude/skills/ and Claude marketplaces from ~/.claude/plugins/known_marketplaces.json (xAI Build docs, 2026-06-12). Native: drop a skill folder into ~/.grok/skills/ (personal) or .grok/skills/ (project). Marketplace sources are also configurable via [[marketplace.sources]] in ~/.grok/config.toml. Verify discovery with `grok inspect`.

Add Solid State

In the TUI: /plugins → Marketplace → add source:

Installs the Solid State plugin — 5 voice skills (voice-check, anti-buzzword, contrast-pair, reframe, compress). Verified live in Grok Build 2026-06-14. The full indexed catalog above runs via Claude-compat, no install needed.

Skills in the catalog

317 indexed skills run on this runtime, including spec-compliant runtime-agnostic skills.
