jx-test

jx-test is a skill for Claude Code, Codex from 1072636071/win-shell-mcp. It costs 94 tokens per session (3,065 once invoked), scanned A, a copy of jx-mode, Apache-2.0.

An extended JX test work mode that combines JX’s cross-platform file and command rules with a requirement to record discovered bugs in the JXK knowledge base.

In plain words
What is it for?
It is for testing win-shell-mcp or JXK, registering their bugs, and using the same standardized tools for file and command operations.
Why use it?
It gives testing sessions a defined way to work and ensures problems found in the supporting tools are captured for follow-up.

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

jx-test scanned grade A with 1 finding 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.

JX Test 模式细则

JX Test 模式 = JX 模式(标准能力 + 规则一、二)+ 规则三(bug 登记)。规则要点已写在 persona 里,本文件是执行细则。

规则一:工具优先 win-shell-mcp

win-shell-mcp 0.2.0 起全量 58 个工具,下表按操作类型全覆盖。

要做的事 绕开 优先调用
读文件 内置 read / cat / Get-Content fs_read(带行号);要原始全文用 cat
写/覆盖文件 内置 write / 重定向 fs_write(默认 utf-8,支持 gbk 与追加)
定点修改 内置 edit text_replace(pattern 默认字面量、/正则/ 启用正则;字面量模式 $1 原样插入,正则模式才 $1 回引用;多命中须表态——all:true 全量 / maxReplace:N 限量 / 正则尾 g;0 命中报 EINVAL)
找文件路径 内置 glob / find search_glob;按名字递归找用 find;找 PATH 里可执行文件用 search_which
搜内容 内置 grep / grep search_content(跨文件);单文件带上下文用 text_grep;两者的 pattern 与 text_replace 同一套双模语义
列目录 ls / 内置列目录 fs_list(glob 过滤、recursive、sort)
文本切片与统计 head / tail / wc text_head / text_tail / text_wc
文本对比 diff text_diff(行级 unified diff)
复制/移动/删除/建目录 cp mv rm mkdir fs_cp / fs_mv / fs_rm / fs_mkdir
元数据 stat touch du fs_stat / fs_touch / fs_du
当前目录与回显 pwd / echo pwd / echo
执行外部程序 直调 pwsh/bash/cmd run_command(argv 直执行,不经 shell 解析);确需 shell 语法时 shell_exec
环境变量 $env: / export env_get / env_set / env_unset
进程 tasklist / kill process_list / process_kill
包管理 直调 npm/pip pkg_detect 探测 → pkg_run 执行
git 手敲 git 命令 git_status git_add git_commit git_diff git_log git_branch git_checkout git_clone git_pull git_push git_stash(stash 的 push/pop/list/drop 都走它的 action 参数)
HTTP curl / fetch net_get / net_post;下载落盘用 net_download
网络诊断 ping/nslookup/netstat ping / net_dns / net_tcp / net_listen
归档 tar / zip archive_create / archive_extract
校验和 sha256sum hash_file
JSON 取值 jq json_get
系统信息 uname / df / free system_info / system_disk / system_memory / system_path

回退规则

win-shell-mcp 是首选,不是枷锁。以下情况允许回退到内置工具:

  • MCP 未连接或工具不存在:直接用内置工具,无需解释。
  • 调用失败且换内置确实能成:回退一次即可,并在回复中注明「<工具名> 失败(错误码),已回退」。禁止反复重试同一失败调用。
  • 交互式/TUI 场景(需要人实时输入的程序):win-shell-mcp 覆盖不了,改用内置方案并告知局限。
  • 需要沙箱审批语义的场景:DSH 内置 pwsh/write/edit 自带沙箱与审批策略;涉及越权重试时以内置通道为准。

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.
