gws-gmail-forward

A command-line skill for forwarding an existing Gmail message to one or more recipients. It can include a note, attachments, copies, and the original message's attachments.

In plain words
What is it for?
Use it to forward messages, add an explanation above the original, attach extra files, save the result as a draft, or omit the original attachments.
Why use it?
It avoids manually finding and forwarding email in Gmail when forwarding is part of an automated workflow.

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

gws-gmail-forward 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 2d 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.

gws gmail +forward --message-id 18f1a2b3c4d --to [email protected] --cc [email protected]
gws gmail +forward --message-id 18f1a2b3c4d --to [email protected] --body '<p>FYI</p>' --html
gws gmail +forward --message-id 18f1a2b3c4d --to [email protected] -a notes.pdf
gws gmail +forward --message-id 18f1a2b3c4d --to [email protected] --no-original-attachments
gws gmail +forward --message-id 18f1a2b3c4d --to [email protected] --draft

Tips

  • Includes the original message with sender, date, subject, and recipients.
  • Original attachments are included by default (matching Gmail web behavior).
  • With --html, inline images are also preserved via cid: references.
  • In plain-text mode, inline images are not included (matching Gmail web).
  • Use --no-original-attachments to forward without the original message's files.
  • Use -a/--attach to add extra file attachments. Can be specified multiple times.
  • Combined size of original and user attachments is limited to 25MB.
  • With --html, the forwarded block uses Gmail's gmail_quote CSS classes and preserves HTML formatting. Use fragment tags (, , , etc.) — no / wrapper needed.
  • Use --draft to save the forward as a draft instead of sending it immediately.
