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.

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 | $0.00073 | $0.00558 |
| Opus 5 | $0.00036 | $0.00279 |
| Sonnet 5 | $0.00015 | $0.00112 |
| Haiku 4.5 | $0.00007 | $0.00056 |
Grade A, and why
google-chat 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 10d 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.
This is a copy
100% identical to google-chat — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Google Chat
Lightweight Google Chat integration with standalone OAuth authentication. No MCP server required.
⚠️ Requires Google Workspace account. Personal Gmail accounts are not supported.
First-Time Setup
Authenticate with Google (opens browser):
python scripts/auth.py login
Check authentication status:
python scripts/auth.py status
Logout when needed:
python scripts/auth.py logout
Commands
All operations via scripts/chat.py. Auto-authenticates on first use if not logged in.
# List all spaces you're a member of
python scripts/chat.py list-spaces
# Find a space by name
python scripts/chat.py find-space "Project Alpha"
# Get messages from a space
python scripts/chat.py get-messages spaces/AAAA123 --limit 10
# Send a message to a space
python scripts/chat.py send-message spaces/AAAA123 "Hello team!"
# Send a message with file attachment
python scripts/chat.py send-message spaces/AAAA123 "Here's the report" --attachment /path/to/file.pdf
# Send a direct message
python scripts/chat.py send-dm [email protected] "Hey, quick question..."

# Create a new space with members
python scripts/chat.py setup-space "New Project" [email protected] [email protected]
Space Name Format
Google Chat uses spaces/AAAA123 format. Get space names from list-spaces or find-space.
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
Automatically refreshes expired tokens using Google's cloud function.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
