add-gmail

add-gmail is a skill for Claude Code, Codex from sbusso/claudeclaw. It costs 60 tokens per session (1,999 once invoked), scanned A, original, MIT.

An integration guide that adds Gmail to ClaudeClaw, an agent that can work through messaging channels. Gmail can be available as tools for reading, sending, searching, and drafting email, or as a channel that receives emails and sends replies.

In plain words
What is it for?
Use it to connect Gmail, configure Google authentication, and choose between tool-only access and an email-triggered agent channel.
Why use it?
It avoids building the Gmail connection and OAuth setup by hand. You can choose whether email only gives the agent tools or can also trigger it automatically.

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

add-gmail 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 5d 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.

Add Gmail Integration

This skill adds Gmail support to ClaudeClaw — either as a tool (read, send, search, draft) or as a full channel that polls the inbox.

Phase 1: Pre-flight

Check if already applied

Check if src/channels/gmail.ts exists. If it does, skip to Phase 3 (Setup). The code changes are already in place.

Ask the user

Use AskUserQuestion:

AskUserQuestion: Should incoming emails be able to trigger the agent?

  • Yes — Full channel mode: the agent listens on Gmail and responds to incoming emails automatically
  • No — Tool-only: the agent gets full Gmail tools (read, send, search, draft) but won't monitor the inbox. No channel code is added.

Phase 2: Apply Code Changes

Ensure channel remote

git remote -v

If gmail is missing, add it:

git remote add gmail https://github.com/qwibitai/claudeclaw-gmail.git

Merge the skill branch

git fetch gmail main
git merge gmail/main || {
  git checkout --theirs package-lock.json
  git add package-lock.json
  git merge --continue
}

This merges in:

  • src/channels/gmail.ts (GmailChannel class with self-registration via registerChannel)
  • src/channels/gmail.test.ts (unit tests)
  • import './gmail.js' appended to the channel barrel file src/channels/index.ts
  • Gmail credentials mount (~/.gmail-mcp) in src/orchestrator/container-runner.ts
  • Gmail MCP server (@gongrzhe/server-gmail-autoauth-mcp) and mcp__gmail__* allowed tool in agent/runner/src/index.ts
  • googleapis npm dependency in package.json

If the merge reports conflicts, resolve them by reading the conflicted files and understanding the intent of both sides.

Add email handling instructions (Channel mode only)

If the user chose channel mode, append the following to groups/main/CLAUDE.md (before the formatting section):

## Email Notifications

When you receive an email notification (messages starting with `[Email from ...`), inform the user about it but do NOT reply to the email unless specifically asked. You have Gmail tools available — use them only when the user explicitly asks you to reply, forward, or take action on an email.

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.
