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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.01115 |
| Opus 5 | $0.00000 | $0.00558 |
| Sonnet 5 | $0.00000 | $0.00223 |
| Haiku 4.5 | $0.00000 | $0.00112 |
Grade A, and why
cst-simulation-workflow 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
The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CST Simulation Workflow
Use this skill as the workflow and decision layer. Use the CST MCP as the execution layer.
Prefer the repository CST MCP native tools for live session control. Use the vendored cst_runtime_* or cst_toolbox_* wrappers for larger command catalogs, workspace pipelines, result export, parameter sweeps, and optimization helpers.
Operating Modes
First classify the request:
| Mode | Use when | Action |
|---|---|---|
| Plan only | User asks for a scheme, script outline, or workflow | Do not run CST; produce the setup plan and assumptions |
| New project | User wants a new CST case | Select a template, resolve inputs, create a run project |
| Existing project | User provides a .cst path or asks to modify an open project |
Inspect first, then work on a copy unless explicitly told otherwise |
| Parameter sweep | User asks for ranges, cases, or comparison | Use sweep preview before running cases |
| Optimization | User asks to improve S11, gain, bandwidth, coupling, etc. | Hand off to runtime optimization workflow after confirming objective and bounds |
Standard Workflow
- Detect CST MCP availability and CST Design Environment status.
- Determine whether to create a new project, open a copy of an existing
.cst, or only generate a plan. - Identify the simulation class and select a template when appropriate.
- Resolve missing inputs using the parameter policy.
- Present a compact defaults card before expensive solves unless the user already said to use defaults or run directly.
- Build or modify geometry, materials, coordinate system, ports/excitations, boundaries, mesh, solver, and monitors.
- Save the working project before running a solver.
- Run the solver only when the user requested execution or accepted the defaults.
- Extract result tree items and export requested data.
- Validate results against the objective and evidence requirements.
- Generate a concise report with assumptions, files, commands/tools used, result paths, and validation status.
- Close/cleanup the CST project/session and report any nonblocking residual locks or access-denied cleanup messages.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cst-simulation-workflow is a skill published in the GitHub repository Cai-aa/CAE-Agent-Hub (852 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,115 tokens. 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.
