ClimaCoupler.jl AGENTS.md

ClimaCoupler.jl AGENTS.md is an instructions file for Codex, OpenCode from CliMA/ClimaCoupler.jl. It costs 336 tokens per session, scanned A, original, Apache-2.0.

A set of project instructions for ClimaCoupler.jl, a Julia software project for coupling climate models. It points agents to shared engineering guidance and project-specific rules.

In plain words
What is it for?
Use it when working on ClimaCoupler.jl, its shared developer guides, tests, public APIs, or scientifically important configuration.
Why use it?
It helps agents follow the project’s approval boundaries, architecture, performance, testing, and review expectations before changing code.

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

ClimaCoupler.jl AGENTS.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 4d 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.

What it actually says

ClimaCoupler.jl — Agent Guide

Read these documents in the order listed when starting work on this repository.

Before you act: agent autonomy

Before making changes that are externally visible or scientifically consequential (git push, version bumps, reproducibility-test edits, CI config changes, public API renames), check docs/dev-guides/workflow/agent_autonomy.md. The boundaries listed there require explicit user approval.

Shared guides (via DeveloperGuides subtree)

The shared engineering guidelines are vendored as a Git subtree at docs/dev-guides/. Julia's Pkg does not resolve git submodules, so subtree is the standard mechanism across the CliMA ecosystem. The full index lives at docs/dev-guides/AGENTS.md. Start there for:

  • Architecture, design patterns, and cross-repo contracts
  • GPU performance, type stability, and AD compatibility
  • Code style, testing, and PR review

Edits to shared guidelines belong in CliMA/DeveloperGuides, not in the vendored copy here. A scheduled workflow (.github/workflows/update_dev_guides.yml) syncs the subtree monthly.

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.
