+# yatai
+
+Gaijin Entertainment's plugin marketplace for AI coding tools.
+
+Plugins built for internal workflows — code review pipelines, development automation, quality enforcement — published
+for anyone to use.
+
+## Installation
+
+Add the marketplace, then install any plugin:
+
+```
+/plugin marketplace add GaijinEntertainment/yatai
+/plugin install <plugin-name>

+
+Multi-agent code review with adversarial falsification. Parallel reviewers surface issues; a prover applies
+falsification gates to filter false positives. Orchestrated by a stateful MCP server
+([`@gaijin/kensai-review-mcp`](https://www.npmjs.com/package/@gaijin/kensai-review-mcp)).
+
+Requires Node.js 26+ and agent teams (`CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1`).
+
+```
+/plugin install kensai
