workspace GEMINI.md

Instructions for building and extending a Gemini CLI extension that connects to Google Workspace services such as Google Docs. It explains the project's TypeScript layout, sign-in handling, and how tools are registered through the Model Context Protocol.

In plain words
What is it for?
Install dependencies, build the workspace server, add service methods, and register new tools with input validation. Use it when maintaining this Gemini extension.
Why use it?
It gives developers a consistent way to build, run, and extend the extension without guessing where service logic, authentication, or tool definitions belong.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

workspace GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

This is a Gemini extension that provides tools for interacting with Google Workspace services like Google Docs.

Building and Running

  • Install dependencies: npm install
  • Build the project: npm run build --prefix workspace-server

Development Conventions

This project uses TypeScript and the Model Context Protocol (MCP) SDK to create a Gemini extension. The main entry point is src/index.ts, which initializes the MCP server and registers the available tools.

The business logic for each service is separated into its own file in the src/services directory. For example, src/services/DocsService.ts contains the logic for interacting with the Google Docs API.

Authentication is handled by the src/auth/AuthManager.ts file, which uses the @google-cloud/local-auth library to obtain and refresh OAuth 2.0 credentials.

Adding New Tools

To add a new tool, you need to:

  1. Add a new method to the appropriate service file in src/services.
  2. In src/index.ts, register the new tool with the MCP server by calling server.registerTool(). You will need to provide a name for the tool, a description, and the input schema using the zod library.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
