gws-gmail-watch

gws-gmail-watch is a skill for Claude Code, Codex from cblecker/claude-plugins. It costs 20 tokens per session (539 once invoked), scanned A, a copy of gws-gmail-watch, Apache-2.0.

A Gmail watcher that looks for new messages and streams them as newline-delimited JSON, a text format with one JSON object per line. It uses Google Cloud Pub/Sub, a service that delivers messages between systems.

In plain words
What is it for?
Use it to feed new Gmail messages into scripts or data pipelines. It can output selected message details and optionally save each message as a separate JSON file.
Why use it?
It removes the need to repeatedly check Gmail by hand or build the message-streaming setup yourself. You can filter messages by Gmail labels and either keep watching or fetch once.

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-watch 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.

What this file has done since we first saw it
