Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00061 | $0.00419 |
| Opus 5 | $0.00030 | $0.00210 |
| Sonnet 5 | $0.00012 | $0.00084 |
| Haiku 4.5 | $0.00006 | $0.00042 |
Grade A, and why
mailapp-send-email 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 7d 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 it actually says
Mail.app Send Email
Overview
Use the bundled AppleScript to compose and optionally send Mail.app messages with structured inputs (to/cc/bcc/subject/body/attachments).
Quick Start
Run the AppleScript via osascript with --to, --subject, and --body. Pass comma-separated lists for multiple recipients or attachments.
osascript /Users/ivancampos/.codex/skills/mailapp-send-email/scripts/send_mail.applescript \
--to "[email protected]" \
--subject "hello" \
--body "testing"
Inputs
Use these flags. Only --to, --subject, and --body are required.
--tosingle email or comma-separated list--ccoptional comma-separated list--bccoptional comma-separated list--subjectsubject line--bodymessage body--attachoptional comma-separated POSIX file paths--sendoptionaltrue|false(defaulttrue, send immediately)
Behavior
- Create a new outgoing message in Mail.app.
- By default send immediately. If
--send false, leave the draft visible for review. - If
--attachis provided, add each file path as an attachment.
Troubleshooting
- If Mail.app automation prompts appear, grant permissions in System Settings -> Privacy & Security -> Automation.
- If attachments fail, ensure paths are absolute POSIX paths and the files exist.

What ships with it
2 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.
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.

mailapp-send-email is a skill published in the GitHub repository IvanCampos/agents (5 stars, last pushed 6mo ago), licensed MIT. It adds 61 tokens to every session and 419 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
