What is gws-gmail-reply-all?

A Gmail command for replying to a message, while keeping the response in the same conversation thread. It can send the reply or save it as a draft.

Reply to Gmail messages from an automated workflow or command line, with plain-text or HTML content and optional files.

It avoids manually finding the right conversation and preserving its recipients. You can also add recipients, attachments, or exclude people from the reply.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.00847
Opus 5	$0.00010	$0.00424
Sonnet 5	$0.00004	$0.00169
Haiku 4.5	$0.00002	$0.00085

Security

Grade A, and why

gws-gmail-reply-all 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.

gws gmail +reply-all --message-id 18f1a2b3c4d --body 'Draft reply' --draft

Tips

Replies to the sender and all original To/CC recipients.
Use --to to add extra recipients to the To field.
Use --cc to add new CC recipients.
Use --bcc for recipients who should not be visible to others.
Use --remove to exclude recipients from the outgoing reply, including the sender or Reply-To target.
The command fails if no To recipient remains after exclusions and --to additions.
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.

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.
