send-email

send-email is a skill for Claude Code, Codex from flameOnYou/callx. It costs 71 tokens per session (617 once invoked), scanned A, original, GPL-3.0.

A tool for creating email messages with Python and sending them through msmtp, a command-line mail-sending program. It uses a default recipient unless another address is explicitly provided.

In plain words
What is it for?
Use it to send a supplied message as the email body, generate the message in the standard MIME format, and retry the same sending method if delivery fails.
Why use it?
It provides a defined way to turn text into an email and send it, while reducing the risk of accidentally choosing a different recipient without specifying one.

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

send-email scanned grade A with 1 finding 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 4d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/email_sender.py, scripts/send_email_stable.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

Changes

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.
