A local replacement for Google login and selected Google services during development. It imitates Google OAuth and OpenID Connect sign-in, Gmail, Calendar, and Drive APIs without contacting Google.

Use it to test Google login, token exchange and refresh flows, Gmail messages and drafts, Calendar events, or Drive API requests in a local app.

It lets developers test sign-in and Google integrations without real accounts, network calls, or live Google data. Tests can run against predictable local services.

google — Skill for Claude Code by pleaseai/claude-code-plugins

Install

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.

Any agent

npx skills add pleaseai/claude-code-plugins --skill google

Clone the repo

git clone --depth 1 https://github.com/pleaseai/claude-code-plugins

Made for: Claude Code.

Or install emulate, the plugin that ships this one along with the rest of its 11 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00147	$0.05961
Opus 5.5	$0.00059	$0.02384
Sonnet 5.5	$0.00029	$0.01192
Haiku 4.5	$0.00015	$0.00596

Security

Grade A, and why

google scanned grade A with 1 finding 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 today.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 617 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Google OAuth 2.0 / OIDC + Gmail, Calendar & Drive Emulator

OAuth 2.0 and OpenID Connect emulation with authorization code flow, PKCE support, ID tokens, OIDC discovery, refresh tokens, plus Gmail, Google Calendar, and Google Drive REST API surfaces.

Start

Local listeners bind to 127.0.0.1 by default. For access from containers or other machines, pass --host 0.0.0.0 to the CLI or hostname: '0.0.0.0' to createEmulator. Configure --base-url or baseUrl for advertised URLs reachable by those clients.

# Google only
npx emulate --service google

# Default port
# http://localhost:4002

Or programmatically:

import { createEmulator } from 'emulate'

const google = await createEmulator({ service: 'google', port: 4002 })
// google.url === 'http://localhost:4002'
