cfd-hypothesis

cfd-hypothesis is a skill for Claude Code, Codex from csml-rpi/AI-CFD-Scientist. It costs 59 tokens per session (3,154 once invoked), scanned A, original, no licence file.

A skill that turns research literature and a topic into testable ideas for computational fluid dynamics simulations. Each idea is written so the OpenFOAM case-generation process can execute it.

In plain words
What is it for?
Use it after the literature stage to create a list of simulation hypotheses saved for later case generation.
Why use it?
It converts general research findings into specific simulation tests instead of leaving them as broad questions.

Skill for Claude CodeCodex

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/stage_gate_audit.py --out-dir <out-dir> --mode preflight --target-stage hypothesis.

Good fit Use it after the literature stage to create a list of simulation hypotheses saved for later case generation.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

cfd-hypothesis 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 10d 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 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.

cfd-hypothesis is a skill published in the GitHub repository csml-rpi/AI-CFD-Scientist (49 stars, last pushed today), with no licence file. It adds 59 tokens to every session and 3,154 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
