multisim-debug-circuit

multisim-debug-circuit is a skill for Claude Code, Codex from yxy050208/multisim-mcp. It costs 49 tokens per session (536 once invoked), scanned A, original, MIT.

A troubleshooting workflow for Multisim, an application used to design and simulate electronic circuits. It checks circuit files, simulation settings, measurements, and the software environment before making a small reversible fix.

In plain words
What is it for?
Use it for invalid circuit descriptions, simulation convergence failures, incorrect waveforms or bias values, missing outputs, and related Multisim faults.
Why use it?
It separates installation or setup problems from actual circuit faults and avoids changing the original design. It also prevents claiming a problem is fixed without rerunning the simulation and comparing results.

Written for no agent in particular: nothing here depends on one.

Good fit Use it for invalid circuit descriptions, simulation convergence failures, incorrect waveforms or bias values, missing outputs, and related Multisim faults.

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

multisim-debug-circuit 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 5d 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

调试 Multisim 电路

本 skill 引用 Multisim MCP 原始工具名;Harness 默认前缀为 mcp__multisim__

  1. 保存问题描述、原始网表、分析命令、错误日志和已有实验 ID,不覆盖原始设计。
  2. 调用 runtime_status,把安装/COM/模板故障与电路故障分开。
  3. 对结构化设计先调用 diagnose_design;若已有同一设计的完成实验目录,把它作为 experiment_dir 附加。按顺序复核:网表语法、地节点、悬空节点、短路、极性、单位、 偏置、模型、分析命令、采样范围、饱和以及收敛条件。
  4. 若只有实验 ID,先用 get_experiment_summary,再按需读取 lognetlistcommandsreport;不要把二进制文件送入模型上下文。
  5. 提出能够解释故障的最小修改,明确修改前值、修改后值、理由和回滚方法。
  6. 把该最小修改写成明确 DesignPatch,调用 evaluate_design_patch 在同一硬性验收规范 下复测原设计和内存候选。若设计带权威 source_netlist,只有确认需要时才显式允许 候选内存网表再生。不要把 adoption_eligible 当作提交授权。
  7. 检查前后诊断、两次实验和递归 manifest;失败或证据不足时保留“失败/未验证”。
  8. 只有用户另行批准时,才把通过候选交给本机审批绑定的持久化流程。

输出采用“症状—证据—根因—最小修改—复测结果—剩余风险”结构。不要在没有 复测数据时宣称问题已经解决。

English summary

Separate environment failures from circuit defects, inspect bounded evidence, apply the smallest reversible change, rerun into a new output directory, and compare measured results before declaring the issue fixed.

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.
