gws is a command-line tool that provides one interface to Google Workspace services such as Drive, Gmail, Calendar, Sheets, Docs, Chat, and Admin. People and AI agents use it to automate Workspace tasks and receive structured JSON results, while its commands are generated dynamically from Google's Discovery Service. The catalogue contains skills and instructions for using gws.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00019 | $0.00779 |
| Opus 5.5 | $0.00008 | $0.00312 |
| Sonnet 5.5 | $0.00004 | $0.00156 |
| Haiku 4.5 | $0.00002 | $0.00078 |
Grade A, and why
gws-gmail-reply 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 1mo 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.

Examples

gws gmail +reply --message-id 18f1a2b3c4d --body 'Looping in Carol' --cc [email protected]
gws gmail +reply --message-id 18f1a2b3c4d --body 'Adding Dave' --to [email protected]

gws gmail +reply --message-id 18f1a2b3c4d --body 'Draft reply' --draft
Tips
- Automatically sets In-Reply-To, References, and threadId headers.
- Quotes the original message in the reply body.
- --to adds extra recipients to the To field.
- Use -a/--attach to add file attachments. Can be specified multiple times.
- With --html, the quoted block uses Gmail's gmail_quote CSS classes and preserves HTML formatting. Use fragment tags (, , , etc.) — no / wrapper needed.
- With --html, inline images in the quoted message are preserved via cid: references.
- Use --draft to save the reply as a draft instead of sending it immediately.
- For reply-all, use +reply-all instead.
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.
