Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

himalaya scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 305 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Himalaya Email CLI

Himalaya is a CLI email client that lets you manage emails from the terminal using IMAP, SMTP, Notmuch, or Sendmail backends.

This skill is separate from the Hermes Email gateway adapter. The gateway adapter lets people email the agent and uses Hermes' built-in IMAP/SMTP adapter; this skill lets the agent operate a mailbox from terminal tools and requires the external himalaya CLI.

References

  • references/configuration.md (config file setup + IMAP/SMTP authentication)
  • references/message-composition.md (MML syntax for composing emails)

Prerequisites

  1. Himalaya CLI installed (himalaya --version to verify)
  2. A configuration file at ~/.config/himalaya/config.toml
  3. IMAP/SMTP credentials configured (password stored securely)

Installation

# Pre-built binary (Linux/macOS — recommended)
curl -sSL https://raw.githubusercontent.com/pimalaya/himalaya/master/install.sh | PREFIX=~/.local sh

# macOS via Homebrew
brew install himalaya

# Or via cargo (any platform with Rust)
cargo install himalaya --locked

Configuration Setup

Run the interactive wizard to set up an account:

himalaya account configure

Or create ~/.config/himalaya/config.toml manually:

[accounts.personal]
email = "[email protected]"
display-name = "Your Name"
default = true

backend.type = "imap"
backend.host = "imap.example.com"
backend.port = 993
backend.encryption.type = "tls"
backend.login = "[email protected]"
backend.auth.type = "password"
backend.auth.cmd = "pass show email/imap"  # or use keyring

message.send.backend.type = "smtp"
message.send.backend.host = "smtp.example.com"
message.send.backend.port = 587
message.send.backend.encryption.type = "start-tls"
message.send.backend.login = "[email protected]"
message.send.backend.auth.type = "password"
message.send.backend.auth.cmd = "pass show email/smtp"

# Folder aliases (himalaya v1.2.0+ syntax). Required whenever the
# server's folder names don't match himalaya's canonical names
# (inbox/sent/drafts/trash). Gmail is the common case — see
# `references/configuration.md` for the `[Gmail]/Sent Mail` mapping.
folder.aliases.inbox = "INBOX"
folder.aliases.sent = "Sent"
folder.aliases.drafts = "Drafts"
folder.aliases.trash = "Trash"

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
