Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
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.

- NVIDIA SkillSpector warn
SkillSpector: 2 findings, up to high
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 →
- high Privilege Escalation · line 71 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Rogue Agent · line 57 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00017 | $0.01835 |
| Opus 5 | $0.00009 | $0.00918 |
| Sonnet 5 | $0.00003 | $0.00367 |
| Haiku 4.5 | $0.00002 | $0.00184 |
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 6d 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.

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
- Himalaya CLI installed (
himalaya --versionto verify) - A configuration file at
~/.config/himalaya/config.toml - 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.
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.
- 6d ago First seen · 305 lines · 17 tokens per session scan A 0f6c9bb4c0a5
himalaya is a skill published in the GitHub repository NousResearch/hermes-agent (243,598 stars, last pushed today), licensed MIT. It adds 17 tokens to every session and 1,835 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
