Fine to try.

Use Sendmux attachment workflows without wasting model context on base64. Use when uploading, downloading, reading, forwarding, or sending email attachments through Sendmux MCP, CLI, SDKs, or direct HTTP, especially when choosing file_path vs presigned upload URL vs inline base64, reading inbound attachments with mailbox_read_attachment, fetching short-lived download_url links, or attaching local files to outbound mail.

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'sendmux-attachments' ] || [ -L ~/.agents/skills/'sendmux-attachments' ]; then echo 'A skill folder named sendmux-attachments already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Sendmux/skills' "$d" && git -C "$d" checkout --quiet '9d8059b10111943ce08860217a27222f43507686' -- 'skills/sendmux-attachments' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/sendmux-attachments' ~/.agents/skills/'sendmux-attachments' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'sendmux-attachments' ~/.claude/skills/'sendmux-attachments' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
