OpenGauss is a project-scoped Lean workflow orchestrator that gives coding agents a command-line interface for managing formal proof and formalization tasks. It is used with Lean projects to coordinate agents, tooling, backend sessions, and workflows supplied by lean4-skills. The catalogue add-ons operate these Gauss-native workflows.
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.

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 | $0.00052 | $0.01509 |
| Opus 5 | $0.00026 | $0.00754 |
| Sonnet 5 | $0.00010 | $0.00302 |
| Haiku 4.5 | $0.00005 | $0.00151 |
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 8d 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.

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

80% identical to himalaya — 48 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.
How it starts
The opening of the file, as written. The whole thing — 279 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.
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"
Gauss Integration Notes
- Reading, listing, searching, moving, deleting all work directly through the terminal tool
- Composing/replying/forwarding — piped input (
cat << EOF | himalaya template send) is recommended for reliability. Interactive$EDITORmode works withpty=true+ background + process tool, but requires knowing the editor and its commands - Use
--output jsonfor structured output that's easier to parse programmatically - The
himalaya account configurewizard requires interactive input — use PTY mode:terminal(command="himalaya account configure", pty=true)
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.

himalaya is a skill published in the GitHub repository math-inc/OpenGauss (1,260 stars, last pushed 5mo ago), licensed MIT. It adds 52 tokens to every session and 1,509 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 80% identical to himalaya, differing in 48 lines, and is treated as a copy.
