simubridge

simubridge is a skill for Claude Code, Codex from naaomiur/simubridge-skills. It costs 42 tokens per session (1,598 once invoked), scanned A, original, MIT.

A set of tools for creating, inspecting, changing, and simulating MATLAB Simulink models. Simulink is a visual environment for building and testing systems from connected blocks.

In plain words
What is it for?
Use it to audit model topology, search the Simulink library, add blocks, set block parameters, modify models, and run simulations.
Why use it?
It lets an agent examine a model's structure and connections before making changes, helping reveal unconnected ports and invalid block paths.

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

simubridge 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 11d 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 — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.

以下是 SimuBridge MCP 所有工具的详细说明 / Tool reference. 操作前请先 model_audit 了解模型结构。


model_audit — 模型拓扑读取 / Topology Audit

读取模型或子系统的完整块列表与所有连线,涵盖四种类型:Signal(信号线)、Goto/From(隐式标签连接)、Data Store(数据存储连接)、Power(SPS 功率连接)。同时报告未连接端口。

Read full model topology — all blocks + all connections (Signal, Goto/From, Data Store, Power). Reports unconnected/dangling ports.

参数

  • model_name:模型名或子系统路径 / model or subsystem path, e.g. "mymodel" or "mymodel/Sub"
  • depth(默认 2):展开深度 / hierarchy depth

在 Simulink 库中按关键词搜索模块,返回可直接传给 add_block 的库路径。两阶段搜索:全词匹配 → 自动拆分短语回退。

Search Simulink libraries by keyword, returns paths ready for add_block. Two-stage: exact match → phrase fallback.

参数

  • keyword:搜索词 / case-insensitive keyword, e.g. "Multiport Switch"
  • libraries(可选):逗号分隔的库名 / comma-separated library names

add_block — 添加模块 / Add Block

从库向模型添加模块,支持单个和批量两种模式。添加前逐层验证目标路径是否存在。

Add blocks from library to model. Single or batch mode. Validates paths before adding.

参数

  • destination:目标路径 / e.g. "mymodel/Gain1"
  • source:库路径 / library path, or JSON array for batch
  • params(可选):初始参数 JSON / e.g. '{"Gain":"2.5"}'

批量模式 / Batch

[{"name":"Gain1","source":"simulink/Math Operations/Gain","params":{"Gain":"3"}}]

常用库路径 / Common sources

模块 source
Gain simulink/Math Operations/Gain
Sum simulink/Math Operations/Sum
Constant simulink/Sources/Constant
Inport simulink/Sources/In1
Outport simulink/Sinks/Out1
Subsystem simulink/Ports & Subsystems/Subsystem
MATLAB Function simulink/User-Defined Functions/MATLAB Function
Multiport Switch simulink/Signal Routing/Multiport Switch
Terminator simulink/Sinks/Terminator

connect — 连接端口 / Connect Ports

连接两个模块的端口,支持信号线和 SPS 功率连接。自动处理嵌套子系统作用域。支持单连接和批量连接。

Wire two block ports — signal or power (SPS). Handles nested subsystems. Single or batch.

参数

  • model_name:父系统路径 / parent system path
  • src_block / dst_block:模块名 / block names
  • src_port / dst_port:单连接端口号 / single port numbers
  • src_ports / dst_ports:批量,逗号分隔 / batch: "1,2,3"

What ships with it

2 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.

Changes

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.

simubridge is a skill published in the GitHub repository naaomiur/simubridge-skills (3 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 1,598 once invoked, about $0.0002 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 2026-08-31.
