ClimaAtmos.jl CLAUDE.md

ClimaAtmos.jl CLAUDE.md is an instructions file for Claude Code from CliMA/ClimaAtmos.jl. It costs 5 tokens per session, scanned A, a copy of deepseek-harness CLAUDE.md, Apache-2.0.

Project instructions for ClimaAtmos.jl, a GPU-capable computer model of the atmosphere around the whole Earth. It is built to be calibrated using observations and machine-learning methods.

In plain words
What is it for?
Working on global-atmosphere simulations, calibration against data, and machine-learning workflows in the CliMA Earth System Model.
Why use it?
It provides project guidance for a technical scientific codebase that combines atmosphere modelling, data assimilation, and machine learning.

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

ClimaAtmos.jl CLAUDE.md 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 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.

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

100% identical to deepseek-harness CLAUDE.md — 3 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.

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.
