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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00066 | $0.01568 |
| Opus 5 | $0.00033 | $0.00784 |
| Sonnet 5 | $0.00013 | $0.00314 |
| Haiku 4.5 | $0.00007 | $0.00157 |
Grade A, and why
featool-multiphysics 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 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.
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.
How it starts

Supported Physics Domains
| Domain | Examples |
|---|---|
| Heat & Mass Transfer | conduction, convection, diffusion |
| Fluid Dynamics (CFD) | laminar/turbulent flow, Navier-Stokes |
| Structural Mechanics | stress, strain, deformation |
| Electromagnetics | electrostatics, magnetostatics |
| Custom PDEs | user-defined equations in natural math notation |
Solver Integrations
| Solver | Type | Notes |
|---|---|---|
| OpenFOAM | CFD | Open-source, industry-grade CFD |
| FEniCS | FEA/Multiphysics | Python-based FEM framework |
| SU2 | CFD | Aerospace-grade solver |
| Built-in | General FEM | Default solver, no external deps |
Standard Modeling Workflow (6 Steps)
1. Geometry → define 1D/2D/3D shapes (CAD primitives or import)
2. Grid → automatic mesh generation (structured/unstructured)
3. Equation → select physics mode or enter custom PDEs
4. Boundary → assign boundary conditions (Dirichlet, Neumann, Robin)
5. Solve → run solver (built-in or external: OpenFOAM/FEniCS/SU2)
6. Post → visualize results (ParaView, Plotly web plots, export)
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.

featool-multiphysics is a skill published in the GitHub repository mahmoud20138/Tradecraft (15 stars, last pushed 4mo ago), licensed MIT. It adds 66 tokens to every session and 1,568 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.
