Print and mail a real postcard or letter to a US address with Sendpaper, including USPS Certified Mail with tracking and a return receipt. Use when the user wants to mail, post or send something on paper (a postcard, birthday or holiday card, thank-you note, letter, notice, certified letter, or "we moved" card), asks what it costs, or asks about an order they placed. Not for email, texts, packages or non-US addresses.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'send-mail' ] || [ -L ~/.agents/skills/'send-mail' ]; then echo 'A skill folder named send-mail already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '6d2e63f73f845eb5dd94c1debba627d4b6e32fba' -- 'plugins/ryan-tish/sendpaper-plugin/skills/send-mail' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/ryan-tish/sendpaper-plugin/skills/send-mail' ~/.agents/skills/'send-mail' && 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/'send-mail' ~/.claude/skills/'send-mail' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
