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 0 findings 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 9d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

86% identical to himalaya — 36 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Himalaya Email CLI

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

Use this only for explicit Himalaya or local IMAP/SMTP mailbox workflows. For Google Workspace or Microsoft 365 accounts, prefer the native managed-provider skills instead.

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)

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"

What ships with it

4 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.
