📝 Additional Notes (optional)

What this skill does

This skill teaches an AI agent how to operate eppie-console — a cross-platform console mail client — in a deterministic, automation-friendly way.

Covered workflows:

Initialize, unlock, and reset the local vault
Add email accounts (IMAP/SMTP, Proton Mail, decentralized Eppie)
List accounts, folders, contacts, and messages
Sync folders and read messages (with pagination support)
Send messages
Delete messages

Design approach

The skill is structured around normative contracts (exact command lines, stdin shapes, and error codes) that an agent can follow mechanically, plus reference sections (scenarios, examples, decision guides) for context. All sensitive inputs (passwords, account credentials) are passed through stdin, never as command-line arguments.

Files included

Intended audience

Any AI agent (Goose, Claude Desktop, or similar) that needs to automate email operations through a CLI without browser-based OAuth flows.
