multisim-create-experiment

multisim-create-experiment is a skill for Claude Code, Codex from yxy050208/multisim-mcp. It costs 45 tokens per session (1,258 once invoked), scanned A, original, MIT.

Instructions for creating reproducible Multisim circuit experiments and checking their simulated results against theory. Multisim is software for drawing and testing electronic circuits.

In plain words
What is it for?
Building schematics, running SPICE-based simulations, comparing theory with measurements, and producing experiment reports and approved artifacts.
Why use it?
They set clear requirements for circuit assumptions, supported analyses, measurements, and evidence before calling a result verified.

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-create-experiment 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 6d 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.

创建 Multisim 电路实验

本 skill 使用 Multisim MCP 工具。下文写原始工具名;DeepSeek Harness 默认会将其 显示为 mcp__multisim__<工具名>,如果配置使用了不同 serverName,请采用实际前缀。

  1. 收集电路功能、输入输出、供电、频率、容差、分析类型、输出目录和验收指标。 对会改变设计结论的缺失条件先向用户确认。
  2. 调用 runtime_status。完整工作流未就绪时,报告具体缺口,不要反复尝试 COM。
  3. 在生成网表前调用 plan_design_options。展示 2--4 个取舍不同的技术方案,说明 默认推荐、假设、风险和实现路径;规划结果是只读的,不会生成文件或启动仿真。 等用户明确选择 plan_idoption_id 后,调用 select_design_option 锁定摘要。
  4. 调用 prepare_design_specification,展示并补齐电气参数、模块、分析计划和验证门槛。 只有 ready_for_netlist_draft=true 且用户审阅规格后,才能进入下一步;不要把参数完整 表述为拓扑、额定值或仿真已经通过。
  5. 用户明确确认当前规格摘要后调用 prepare_netlist_draft,先展示逻辑模块、网络、待选 器件与派生约束。该结果不是 SPICE;不得把 ready_for_component_resolution 解释为 已可成图或仿真。
  6. 调用 resolve_component_requirements 展示候选器件族、额定值计算依据和模型来源状态。 用户提交具体型号、额定值和模型摘要后,调用 approve_component_resolution 绑定人工 审阅。只有审批凭证的 ready_for_executable_netlist=true 时,才可调用 compile_executable_netlist。当前编译器只支持 signal-passive 的明确器件族组合;其他 方案应报告支持缺口,不得自行拼接引脚。编译结果仍需向用户展示 SPICE、计算值、假设和 门禁,并停在 approve_executable_netlist;没有新的明确审批前不得成图或仿真。外部模型 只允许来自服务端受限模型根目录,并必须重新哈希。
  7. 得到另行批准的完整网表和分析计划后,成图阶段将编译预览、网表审批凭证和其中的原样 spice_netlist 传给 create_schematic_from_netlist;该工具会重新校验绑定关系,只写入 获批原理图而不启动仿真。随后调用 approve_simulation_plan,把同一网表审批绑定到 ExperimentSpec 的安全命令、测量信号和验收限制;再将三份凭证传给 run_verified_circuit_experiment,由入口在成图和仿真前重新校验。有明确验收指标时优先调用 run_verified_circuit_experiment;长任务可将同三份凭证传给 submit_circuit_experiment,凭证会随作业保存并在隔离 worker 中再次校验;普通实验仍可调用 run_circuit_experiment,长任务则查询提交作业的状态。 如果用户从工作台下载了 multisim-approved-experiment-handoff.json,可以先在可信终端 执行 multisim-mcp execute-handoff --handoff <file> --root <project> --json 做一致性校验; 只有用户明确确认后才加 --confirm,命令会严格先成图、再仿真,且默认不覆盖已有产物。 时间较长时可使用 --submit --confirm:先成图,再将仿真计划排入 durable worker,并把返回 的 job 句柄交给工作台队列观察。
  8. 成功后调用 get_experiment_summarylist_experiment_artifacts。只有需要更多 文本证据时才分页调用 read_experiment_artifact,不要读取二进制内容。 受控审批运行还应通过 inspect-project 或工作台回读目录 manifest,确认 approval_provenance 与当前 simulation-plan/netlist/compiled/spec 摘要一致; 旧实验或直接执行结果若显示未记录归属,不得冒充本次审批结果。
  9. 核对理论值、仿真测量、容差和验证结论。任何缺少数据支持的指标标记为“未验证”。
  10. 仅在用户要求导出时调用 export_experiment_artifact;导出目录必须已由服务端批准。

最终答复应列出电路假设、网表/分析、关键测量、PASS/FAIL/未验证结论和产物清单。 不要把“最接近要求”写成“通过”,也不要声称自动生成的设计已可直接生产。

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.

multisim-create-experiment is a skill published in the GitHub repository yxy050208/multisim-mcp (9 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 1,258 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.
