Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.04448 |
| Opus 5.5 | $0.00025 | $0.01779 |
| Sonnet 5.5 | $0.00013 | $0.00890 |
| Haiku 4.5 | $0.00006 | $0.00445 |
Grade A, and why
email 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 today.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Email Management
Manage emails using Himalaya CLI - a powerful command-line email client supporting IMAP, SMTP, Maildir, and Notmuch backends.
Config format note (Himalaya v2.x). Himalaya v2 reorganized the config from the old
backend.*/message.send.backend.*schema into per-protocol tables ([accounts.x.imap],[accounts.x.smtp],[accounts.x.jmap]). A v1 config silently loads with zero backends, so every command fails withNo backend matching `auto` is configured. If you see that error, the config is in the wrong format — see references/providers.md for the v2 shape.account listshows the resolved backends per account; use it to confirm.
Agent Usage (Power User Patterns)
When using this skill as an agent, run commands via execute_command. Prefer these patterns:
-
Install and set up if needed. Run Prerequisites Check before the first Himalaya command. If
himalayais missing, fetch the live README and install it. If no account is configured, walk the user through Account Setup, then continue the original request (check mail, etc.). Do not stop at "go install Himalaya". -
Always use
--json(the global flag) when you need to parse results (subject, from, id):himalaya envelope list -m INBOX -s 20 --json | jq '.envelopes[] | {id, subject, from, date}'Note: in v2 the flag is the global
--json, not--output json.envelope listemits{"envelopes":[...]};account listemits{"accounts":[...]}. -
Non-interactive send uses
message writewith flags and--send(no editor):himalaya message write --to "[email protected]" --subject "Subject" --body "Body text" --sendOr feed the body via stdin:
printf 'Body text' | himalaya message write --to "[email protected]" --subject "Subject" --send--save <MAILBOX>appends a copy (e.g. Sent) alongside--send.
What ships with it
1 file 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.
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.

email is a skill published in the GitHub repository lvndry/jazz (54 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 4,448 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
