This extension provides documentation support for using the Agent Development Kit (ADK).

How It Works

This Gemini CLI extension uses the MCP LLMS-TXT Doc Server to provide the Gemini model with up-to-date information about ADK. The documentation content is sourced from the llms.txt file in the official ADK-Docs. This file is effectively a sitemap of the ADK documentation.

The extension's GEMINI.md file provides instructions to the Gemini model, guiding it to use the tools provided by this extension when answering questions about ADK.

Why Is This Useful?

This extension empowers Gemini CLI to provide accurate and current information about ADK, without relying on potentially outdated internal knowledge. This is particularly useful for:

• Answering questions about ADK's features and APIs.
• Assisting with development tasks related to ADK.
• Ensuring that the information provided by the Gemini CLI is consistent with the latest ADK documentation.

Extension Installation into Gemini CLI

The easiest way to install this extension is with this command:

gemini extensions install https://github.com/derailed-dash/adk-docs-ext

The command will respond with:

Extension "adk-docs-ext" installed successfully and enabled.

Alternatively, you can clone this repo directly into your extensions folder.

For global installation:

mkdir -p ~/.gemini/extensions
git clone https://github.com/derailed-dash/adk-docs-ext.git ~/.gemini/extensions/adk-docs-ext

For workspace-level installation:

mkdir -p ./.gemini/extensions
git clone https://github.com/derailed-dash/adk-docs-ext.git ./.gemini/extensions/adk-docs-ext

Gemini CLI will automatically load the extension on startup and will then use the relevant tools to answer any questions relating to ADK.

Using an Alternative llms.txt Path

You may prefer to specify an alternate location for your llms.txt, such as a local copy of the file that you generate using a custom tool.

To use it, amend the gemini-extension.json and replace this:

    "--urls",
    "https://google.github.io/adk-docs/llms.txt",

with this:

    "--urls",
    "Local_ADK_Docs:/path/to/local/llms.txt",

E.g. if you're using the provided sample:

{
  "name": "adk-docs-ext",
  "version": "1.0.2",
  "mcpServers": {
    "adk-docs-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "mcpdoc",
        "mcpdoc",
        "--urls",
        "Local_ADK_Docs:${extensionPath}/sample_llms_txt/local_adk_docs_llms.txt",
        "--allowed-domains",
        "*",
        "--transport",
        "stdio"
      ]
    }
  },
  "contextFileName": "GEMINI.md"
}
