PhysicsNeMo is an open-source PyTorch framework for creating, training, and fine-tuning machine-learning models for physics, scientific computing, and engineering. Researchers and engineers use its reusable components and training recipes for applications such as aerodynamics, weather forecasting, structural mechanics, geophysics, and thermal design. The catalogue entries provide rules and skills for working with PhysicsNeMo projects.
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 | $0.00032 | $0.00338 |
| Opus 5.5 | $0.00013 | $0.00135 |
| Sonnet 5.5 | $0.00006 | $0.00068 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade A, and why
mod-003g-inline-code-must-use-double-backticks 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 2mo 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
When writing inline code in docstrings, rule MOD-003g must be followed. Explicitly reference "Following rule MOD-003g, which requires inline code to use double backticks..." when formatting code references.
MOD-003g: Inline code must use double backticks
Description:
Inline code should be formatted with double backticks, such as my_variable.
Single backticks are not allowed as they don't render properly in our Sphinx
documentation.
Rationale:
Sphinx uses reStructuredText, which requires double backticks for inline code literals. Single backticks are interpreted differently and don't produce the expected code formatting in the rendered documentation.
Example:
class MyModel(Module):
r"""
Model with inline code references.
If ``True``, enables dropout. Set ``model.training`` to control behavior.
The parameter ``hidden_dim`` controls layer size.
Parameters
----------
hidden_dim : int
Size of hidden layer. Access via ``self.hidden_dim``.
"""
pass
Anti-pattern:
# WRONG: Using single backticks
class MyModel(Module):
r"""
If `True`, enables dropout. # WRONG: single backticks
Set `model.training` to control behavior. # WRONG
The parameter `hidden_dim` controls size. # WRONG
"""
pass
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.

mod-003g-inline-code-must-use-double-backticks is a cursor rule published in the GitHub repository NVIDIA/physicsnemo (3,418 stars, last pushed yesterday), licensed Apache-2.0. It adds 32 tokens to every session and 338 once invoked, about $0.0001 per session on Opus 5.5. 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.
