概覽

AI 產生的概覽

本機 MCP 伺服器，內建 100 項系統與硬體工程技能，涵蓋需求、介面、預算與驗證工作。

可以做什麼
  • 清理、擷取並對應試算表與 PDF 中的需求，衍生或比對父階與子階需求
  • 依 ECSS 版本審查需求、找出衝突，並建立驗證矩陣或評估測試結果
  • 審查電氣與機械介面，建立含餘裕的功率與質量預算
  • 審查環境鑑定涵蓋範圍、FMEA 遺漏項目、DO-254 保證證據以及招標符合性矩陣
  • 比較規格書版本，產出變更登錄與驗證影響
適用情境
適合系統與硬體工程師，讓助理在專用的本機資料夾中處理需求登錄表、介面規格、預算、驗證證據與標準審查。
執行需求
透過 uvx 從 arc-engineering-mcp 這個 PyPI 套件以 stdio 在本機執行，需要 Python 3.11+ 與 uv。環境變數 ARC_ENGINEERING_WORKSPACE 必須指向一個既有的專用資料夾，用來存放輸入與輸出。不需要模型 API 金鑰。
安裝前請注意
伺服器會讀寫所設定工作區資料夾中的檔案，應指向專用目錄而非家目錄。對話內容仍會由你的 AI 供應商處理，ChatGPT 上傳則依該服務的政策。ECSS 等標準未隨附，需自行提供授權副本。工程修改僅為供審閱的建議，助理本身可能產生費用。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Arc Skills，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

🚀 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 Do not publish or upload my files.If you cannot run a local MCP, read the attached catalogue and load only theselected skill and its references for this conversation.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.
