100 systems and hardware engineering skills for requirements, interfaces, budgets and verification.

已验证STDIO仅桌面文件与存储开发者工具

概览

AI 生成的概览

本地 MCP 服务器，提供 100 项系统与硬件工程技能，覆盖需求、接口、预算、验证与评审。

可以做什么
清理、提取、派生、比对和评审需求，包括对照 ECSS 版本和招标条款，并保留页码引用与待定问题。评审电气与机械接口，找出缺失或不一致的参数与图纸细节。按工作模式构建功率与质量预算，标出余量和未确定负载。评估验证矩阵、测试结果、环境鉴定覆盖、FMEA 遗漏和 DO-254 保证证据。比对规格版本并生成变更登记表。
适用场景
适合处理需求表格、规格 PDF、接口图纸、预算或验证证据的系统与硬件工程师，用于生成保留原文的结构化评审草稿。更适合 Codex、Claude Desktop 等本地 MCP 客户端，而非仅网页版对话。
运行要求
通过 uvx 从 arc-free-skills 的 PyPI 包以 stdio 在本地运行，需要 Python 3.11+ 和 uv。环境变量 ARC_FREE_SKILLS_WORKSPACE 必须指向一个已存在的专用文件夹，用于输入和新输出，不能使用主目录。无需模型 API 密钥。仅限桌面端。
安装前请注意
工作区文件在本地处理，但对话中使用的内容仍会发送给 AI 提供商，ChatGPT 上传遵循其自身政策。ECSS 等标准未随附，需自行提供授权副本。工程修改只是供审阅的建议，并非已批准的变更。AI 助手本身可能产生费用。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Arc Free Skills，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

🚀 Get started

Download this repo using Code → Download ZIP. Open the unzipped folder in Codex, or attach the ZIP to a ChatGPT conversation that supports file analysis.

Copy and paste this setup prompt:

text
Set up Arc Skills from:https://github.com/ArcHelps/systems-engineering-skillsUse the repository or ZIP I provided, or fetch the public repository if your tools allow it.Read README.md and docs/SETUP.md, then choose the route this client supports.If you can run local commands, install the locked dependencies, connect the localMCP to Codex using the documented configuration, and check skill discovery.Use a dedicated arc-engineering-work folder for inputs and new outputs.Keep my existing settings and source files intact. Do not publish or upload my files.If you cannot run a local MCP, read the attached catalogue and load only theselected skill and its references for this conversation. Explain any unavailable tools.Show me five relevant skills and run the synthetic requirements example if possible.Say which route actually worked and whether I need to restart or enable anything.
Where you use itWhat works
Codex on your computerLocal MCP with all 100 skills and file tools. Recommended.
ChatGPT webAttached skill instructions + ChatGPT's available file tools. This does not install the MCP.
Claude Desktop / other local MCP clientsThe same local MCP; connection instructions.

Local setup needs Python 3.11+ and uv. No model API key needed.

💬 Try it

Attach a file or place it in your configured work folder, then paste a prompt:

Clean requirements

text
Use Arc Skills to clean and map customer-requirements.xlsx.Preserve every source ID and original statement. Show the field mapping,duplicate IDs, TBDs/TBCs, missing information and unresolved links.Give me a cleaned workbook and an import proposal. Reconcile all row counts.

Review a specification

text
Use Arc Skills to extract and review this requirements PDF.Keep page references, notes, figures and deleted requirements visible.Give me a requirements table and the most consequential issues first:contradictions, broken references, unclear limits and unverifiable statements.Separate confirmed problems from ambiguities. Don't invent missing values.

Review against ECSS

text
Use Arc Skills to review REQ-014 against the ECSS-E-ST-10-06 editionI attached. Cite the inspected criteria, explain each finding and proposethe smallest correction. Preserve the original wording beside the proposal.If you cannot inspect the applicable standard, label the review advisory.

Build a power budget

text
Use Arc Skills to build a system power budget from component-loads.xlsx.Separate standby, nominal and peak demand by operating mode. Preserve units,quantities, duty cycles and source values. Show demand against the suppliedpower limits, conversion losses, missing loads and remaining margin.Don't assume every peak load operates simultaneously or invent missing values.

No file yet?

text
Use Arc Skills to review this requirement:"The unit shall provide an appropriate warning quickly."Explain what is missing and propose clearer wording without inventing a latency.

🔒 Your files

The local MCP processes files in your chosen folder without uploading them to an external server. Your assistant and its AI provider still process the content used in the conversation. ChatGPT uploads follow ChatGPT's policies. Data flow →

The skills and code are free under the MIT license. Your AI assistant may have its own charges. Standards are not bundled; provide authorized copies when needed. Engineering edits are proposals for your review, with source wording preserved.
