che-word-mcp: Instructions file for Claude Code

CLAUDE.md

che-word-mcp CLAUDE.md is an instructions file for Claude Code from PsychQuant/che-word-mcp. It costs 1,295 tokens per session, scanned A, original, MIT.

Project instructions for developing and packaging a Swift server that provides many CheWordMCP tools. They document the project layout, where its compiled program belongs, and where its packaged MCPB file must be stored.

In plain words
What is it for?
Use them when changing the Swift server, building its release binary, copying it to development or package locations, creating an MCPB package, or updating its version files.
Why use it?
They prevent common mistakes in compiling, copying, packaging, and versioning the server. MCPB is a package format for distributing an MCP server to compatible tools.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is PsychQuant/che-word-mcp's own configuration. It tells Claude Code how to work on che-word-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything che-word-mcp configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/che/Developer/macdoc(Word→MD.

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

che-word-mcp CLAUDE.md 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 28d 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.

重要路徑規則

Binary 安裝位置

  • 本地開發: ~/bin/CheWordMCP
  • mcpb 打包: mcpb/server/CheWordMCP

mcpb 打包檔位置

  • 正確: mcpb/che-word-mcp.mcpb
  • 錯誤: 專案根目錄(不要放在這裡!)

編譯與部署流程

# 1. 編譯
swift build -c release

# 2. 複製 binary 到安裝位置
cp .build/release/CheWordMCP ~/bin/
cp .build/release/CheWordMCP mcpb/server/

# 3. 打包 mcpb(在 mcpb/ 目錄內執行)
cd mcpb && zip -r che-word-mcp.mcpb . && mv che-word-mcp.mcpb ../mcpb/
# 或
cd mcpb && zip -r che-word-mcp.mcpb .

版本更新 Checklist

更新版本時需要修改:

  1. mcpb/manifest.json - version 欄位
  2. CHANGELOG.md - 新增版本條目
  3. README.md - 工具數量等資訊(如有變動)
  4. 新增/移除某工具的「目前未實作」註記時,同步更新 README.md 與 README_zh-TW.md 裡對該工具(或該工具所屬能力分類,如 Watermark CRUD) 的敘述——工具數量不變時上面第 3 項不會觸發,但過度宣稱能力(description 誠實、README 卻仍寫成可用 CRUD)是使用者會直接被誤導的落差(#210)。
  5. Sources/CheWordMCP/Server.swift 的 static let serverVersion—— MCP initialize handshake 回報給 client 的版本,單一來源(Server(...) 建構時直接讀這個常數,不要再改回內嵌字面量)。這個常數曾經漏改超過 兩個大版本(#211)。
  6. server.json——version、packages[0].version、 packages[0].identifier(下載網址裡的 vX.Y.Z)三處都要跟著改; packages[0].fileSha256 由 scripts/release.sh 在發版成功後自動寫回, 不要事先手填(見下段)。

以上六項中,第 1、5、6 項(manifest.json/serverVersion/server.json 的 version 與 identifier)由 scripts/release.sh 的 [0.3/7] 步驟在建置前 fail-fast 檢查。server.json 的 fileSha256 是簽章後 binary 的 sha256, 而 codesign --timestamp 每次簽章都會嵌入新的時間戳,同一份 bytes 簽兩次 sha 就不同,所以發版前不可能知道正確值:scripts/release.sh 在 [post] 步驟把這次實際的 sha 寫回 server.json,發版後要 commit 這個變更(下一次 發版的乾淨工作樹檢查會擋住沒 commit 的情況)。第 5 項另有 Issue211VersionConsistencyTests(swift test) 鎖住 serverVersion 與 mcpb/manifest.json 的一致性,每次 swift test 都會跑,不必等到真的要發版才發現漏改(#211)。

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.
