Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/sanjay3290/ai-skills --skill google-chat
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads google-chat automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

SKILL.md

The instructions your agent reads when the skill is triggered.

Google Chat

Lightweight Google Chat integration with standalone OAuth authentication. No MCP server required.

⚠️ Requires Google Workspace account. Personal Gmail accounts are not supported.

Everything is sent as the authenticated user, so treat write commands as outward-facing: confirm the exact text with the user before posting to a space, and never send to a channel the user did not name.

First-Time Setup

pip install -r requirements.txt
python scripts/auth.py login     # opens browser
python scripts/auth.py status    # verify
python scripts/auth.py logout

Commands

All operations via scripts/chat.py. Auto-authenticates on first use if not logged in.

Reading

python scripts/chat.py get-messages spaces/AAAA123 --limit 10
python scripts/chat.py get-messages spaces/AAAA123 --limit 10 --raw   # full JSON
python scripts/chat.py get-message spaces/AAAA123/messages/XYZ
python scripts/chat.py list-threads spaces/AAAA123
python scripts/chat.py list-spaces
python scripts/chat.py find-space "Project Alpha"    # ignores punctuation/spacing
python scripts/chat.py list-members spaces/AAAA123

Read output is compact by default — one block per message with its timestamp, sender, text and resource name. That is roughly 14x smaller than the raw API payload, which matters when an agent is paying for every token it reads. Use --raw when you need the full JSON.

Writing

python scripts/chat.py send-message spaces/AAAA123 "Hello team!"
python scripts/chat.py send-dm user@example.com "Hey, quick question..."
python scripts/chat.py reply-in-thread spaces/AAAA123 spaces/AAAA123/threads/T "Following up."
python scripts/chat.py send-media spaces/AAAA123 "Latest mocks" --file a.png --file b.png
python scripts/chat.py edit-message spaces/AAAA123/messages/XYZ "Corrected text."
python scripts/chat.py delete-message spaces/AAAA123/messages/XYZ
python scripts/chat.py delete-message spaces/AAAA123/messages/XYZ --force   # has thread replies
python scripts/chat.py add-reaction spaces/AAAA123/messages/XYZ 👍
python scripts/chat.py setup-space "New Project" user1@example.com user2@example.com
python scripts/chat.py find-dm user@example.com

Add --dry-run to any write command to print the request instead of sending it. Use it when wiring up or testing a flow so nothing lands in a real channel. (For send-dm it reports the resolved recipient rather than the DM space, since resolving that needs a live call.)

Editing and deleting

send-message, send-dm and send-media return the created message's name (spaces/X/messages/Y) — that is what edit-message, delete-message and add-reaction take. You can only edit or delete messages you sent. To fix an older message, find its name with get-messages first.

Attachments

send-media takes a repeatable --file. Google Chat accepts several attachments on one message only when every attachment is media (image or video); a mixed batch is split automatically into one message per file, with the caption on the first. --attachment is still accepted as an alias for a single --file.

Optional aliases

Typing full email addresses and spaces/AAAA... IDs is tedious, and having an agent call list-spaces to find a channel it uses daily is slow. Copy directory.example.json to directory.json and map short names:

{
  "users":  { "alex": "alex@example.com" },
  "spaces": { "team": { "id": "spaces/AAAAxxxxxxx", "name": "My Team" } }
}

Then send-message team "Deploying now" and send-dm alex "..." both resolve locally, with no API call. Full emails and spaces/... names keep working everywhere.

directory.json is personal and gitignored. It is entirely optional — without it every command still works, and an unresolvable alias fails immediately with the list of valid ones rather than silently falling back to a scan.

Message formatting

Chat supports *bold*, _italic_, ~strike~, `code`, triple-backtick code blocks, and <url|label> links. It does not support Markdown headings, tables, or []( ) links — they render literally.

Token Management

Tokens stored securely using the system keyring:

  • macOS: Keychain
  • Windows: Windows Credential Locker
  • Linux: Secret Service API (GNOME Keyring, KDE Wallet, etc.)

Service name: google-chat-skill-oauth. Expired tokens refresh automatically.
