Overview
An installable agent skill that lets your AI coding agent print and physically mail a document (PDF, HTML, Markdown, text, DOCX, or image) to a US postal address via the PostAgent API. Each send is paid per-call in USDC on Base using the x402 payment protocol, then handled by PostAgent's print-and-mail workflow. > Sending mail spends real money and is irreversible once submitted. The > skill always quotes first and requires explicit user confirmation before > paying. Claude Code (global) — always pass -a claude-code so it lands in ~/.claude/skills/, the only place Claude Code reads skills from:
