Include file attachments in emails

Example prompts

“/send-email”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Run the Skill and Get Run ID
Open Workflow in Browser and Wait for Completion
Confirm Action Status

What it can do on your machine

Read from SKILL.md and the folder at commit 5a546d2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- jq
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- refly.ai
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Send Email loads about 540 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 90 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~45
When it runs · the whole SKILL.md, loaded when a task matches: ~540

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 90 words (~540 tokens).

“Send emails with HTML content. Use when you need to: (1) send emails to recipients, (2) compose HTML formatted email content, or (3) include file attachments in emails.”
