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

email 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 10d 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.

Email

Run the external himalaya binary via blue exec when the task is about a real mailbox.

Himalaya is a CLI email client that supports IMAP, SMTP, Notmuch, and Sendmail backends. It can list folders, search envelopes, read full messages, compose drafts, send replies, move/archive mail, manage flags, and download attachments.

Prefer This Skill When

  • The user explicitly mentions himalaya
  • The user explicitly mentions email
  • The task is about a real inbox, IMAP/SMTP account, or terminal email workflow
  • The user wants a CLI path for listing, reading, replying to, archiving, or sending emails
  • The user is using multiple mail accounts and wants account-aware commands

Do not prefer this skill for benchmark-local email fixtures already stored in the workspace like inbox/ unless the user explicitly asks for Himalaya or a real mail backend.

Prerequisites

  1. Verify the CLI exists:
blue exec command="himalaya --version"
  1. Configure an account interactively:
blue exec command="himalaya account configure"
  1. 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"

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"

Task Routing

User Intent Action
List folders/accounts blue exec command='himalaya folder list' / blue exec command='himalaya account list'
Search inbox or unread mail blue exec command='himalaya envelope list --output json ...'
Read a message body blue exec command='himalaya message read <id>'
Export raw MIME blue exec command='himalaya message export <id> --full'
Reply, forward, or compose blue exec command='himalaya message reply <id>' / blue exec command='himalaya message forward <id>' / blue exec command='himalaya message write'
Send a prepared message blue exec command='himalaya template send'
Archive or move mail blue exec command='himalaya message move <id> \"Archive\"'
Download attachments blue exec command='himalaya attachment download <id>'

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.
