knowledge-catalog is a Gemini CLI extension (plugin) that provides a set of agent skills for interacting with Knowledge Catalog (formerly known as Dataplex) instances. It lets AI agents such as Antigravity, Claude Code, and Codex discover, manage, monitor, and govern data and AI artifacts across a data platform using natural language prompts. The README states the project is currently in beta (pre-v1.0) and may see breaking changes before the first stable release. It requires a Google Cloud project with the Dataplex API enabled, Application Default Credentials, and specific IAM roles (Dataplex Data Reader and Service Usage Consumer). The repository currently offers one skill, 'Knowledge Catalog Discovery', for searching and exploring catalog metadata.

Overview

According to the README, Knowledge Catalog (formerly Dataplex) is a Google Cloud service for cataloging and governing data and AI assets; this repository provides agent skills that connect AI coding/agent tools to that service so users can query and explore catalog metadata via natural language instead of complex commands.

What you can do with knowledge-catalog

  • Explore catalog entries and metadata by describing requests in plain English (e.g., "Find all catalog entries related to 'customer orders'")
  • Look up descriptions and owners for specific catalog entries (e.g., 'customer_pii')
  • Compare columns across datasets (e.g., find similar columns across marketing and sales datasets)
  • Perform ad-hoc analysis such as calculating totals over a time period
  • Use the 'Knowledge Catalog Discovery' skill to search entries, look up metadata, and explore aspect types
  • Install the skills into Antigravity, Claude Code, Codex, or via the npx skills tool
  • Generate data classes or code snippets based on table schemas (per the README's stated benefits)
