Grok Build reads Claude Code marketplaces, plugins, skills, MCPs, agents, hooks and instruction files natively (per xAI’s own compatibility contract), so the Nika kit installs unported. Binary first (brew install supernovae-st/tap/nika · other paths):
--trust is load-bearing, not ceremony: without it grok refuses the install outright (plugins can run hooks, MCP servers and skills on your machine), and even a later trust grant is what activates the plugin’s hooks and MCP.

​
Zero-config on a Claude Code machine

If the machine already runs the Nika plugin in Claude Code, grok picks up the marketplace and the components from the Claude surfaces on its own · components dedup by name and a grok-side install takes priority. Verified live: adding the marketplace answered already configured before we ever taught grok about it.

​
What loads (verified live 2026-08-02 · grok 0.2.117 · nika 0.107.0)

  • the 4 skills (authoring · debugging · operating · migration)
  • the 6 /nika:* commands (check · explain · new · trace · permits · doctor)
  • the 3 subagents (nika:nika-author · nika:nika-debugger · nika:nika-migrator)
  • the hook file (session map · check-on-edit · guard-run · claude dialect, registered as a unit)
  • the read-only MCP oracle (9 tools · no execution by design)

​
Prove it (deterministic · no model call · CI-able)

Trust those two outputs, not a model’s enumeration · inspect names each loaded skill, agent, hook and MCP server with the file it came from.

​
Optional native presence

The project .mcp.json that ships with the kit is read natively. For a machine-level stanza in grok’s own dialect:

​
Caveats worth knowing

  • Plugins stay OFF until enabled, and a plugin’s hooks and MCP stay inactive until trusted · the refusal message teaches the exact re-run.
  • Enterprise deployments can require pinned-commit installs (require_sha) · release tags satisfy it.
  • Grok enforces version floors at startup · pin deliberately in CI.
Then nika init in the repo · the agent-teaching surface (AGENTS.md, the .agents/skills authoring skill, editor wiring) is read natively and is what makes the oracle useful (agents guide).
