What it does
Pwsh is an agent skill from BiFangKNT/mtga. 在 Windows PowerShell 5.1 与 PowerShell 7 中编写和执行稳定命令，重点处理引号、管道符、原生命令参数传递与跨版本兼容。遇到 --jq/过滤表达式被 PowerShell 误解析、同一命令在 pwsh5 与 pwsh7 行为不一致、或需要为 pwsh7.3+ 增加参数传递适配时使用此 skill。
Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `agents/openai.yaml`, `references/pwsh5-baseline.md` and `references/pwsh7-adaptation.md`).
It works with PowerShell. The repository describes itself as: 基于本地代理的方式，绕过 IDE 的固定模型服务商限制. The licence is AGPL-3.0.
Example prompts
- “/pwsh”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 确认目标解释器：先读取 $PSVersionTable.PSVersion，判断是 5.1 还是 7.x。
- 选兼容级别：默认按 pwsh5 语法生成；仅在确认 7.x 时使用 7 专属语法。
- 组装参数：优先用变量或数组传参，避免在命令行内堆叠转义。
- 处理原生命令：当参数被误解析时，先改写引号；必要时使用 --% 或 pwsh7 参数传递设置。
- 输出结果：明确命令、兼容前提、以及可能影响行为的版本差异。
What it can do on your machine
Read from SKILL.md and the folder at commit 72669fb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pwsh loads about 338 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 101 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- 在 Windows PowerShell 5.1 与 PowerShell 7 中编写和执行稳定命令，重点处理引号、管道符、原生命令参数传递与跨版本兼容。遇到 `--jq`/过滤表达式被 PowerShell 误解析、同一命令在 pwsh5 与 pwsh7 行为不一致、或需要为 pwsh7.3+ 增加参数传递适配时使用此 skill。
Pwsh
Overview
以“先兼容、后增强”为原则生成 PowerShell 命令。默认先满足 pwsh5 可运行，再按需启用 pwsh7 专属能力。
Workflow
- 确认目标解释器：先读取
$PSVersionTable.PSVersion，判断是 5.1 还是 7.x。 - 选兼容级别：默认按 pwsh5 语法生成；仅在确认 7.x 时使用 7 专属语法。
- 组装参数：优先用变量或数组传参，避免在命令行内堆叠转义。
- 处理原生命令：当参数被误解析时，先改写引号；必要时使用
--%或 pwsh7 参数传递设置。 - 输出结果：明确命令、兼容前提、以及可能影响行为的版本差异。
Baseline Rules
- 将 pwsh5 视为最低兼容基线。
- 在 PowerShell 中向
--jq或类似参数传入含|的表达式时，必须使用单引号字符串。 - 需要变量拼接时，先构造变量再传参，不在命令行直接拼复杂引号。
- 文件读写显式指定编码，避免依赖不同版本默认值。
pwsh7 Adaptation
- 仅在确认
PowerShell 7.3+时考虑$PSNativeCommandArgumentPassing影响。 - 旧脚本因参数传递行为变化失败时，按需临时切换
Legacy，任务完成后恢复原值。 - 使用 pwsh7 专属语法（如
??、||、&&、ForEach-Object -Parallel）前先做版本判断。
Failure Handling
- 出现
|被吃掉：检查表达式是否被单引号包裹。 - 原生命令参数异常：先改为变量传参，再评估
--%或$PSNativeCommandArgumentPassing。 - 跨版本结果不同：回显版本号与关键变量值后，再给出兼容改写命令。
Output Format
Plan: 要解决的 PowerShell 兼容问题。Commands: 可直接执行的命令（必要时分 5.1 与 7.x 两套）。Result: 关键输出与版本信息。Compat: 是否依赖 pwsh7 特性，及回退方案。

Questions about Pwsh
What does Pwsh do?
在 Windows PowerShell 5.1 与 PowerShell 7 中编写和执行稳定命令，重点处理引号、管道符、原生命令参数传递与跨版本兼容。遇到 --jq/过滤表达式被 PowerShell 误解析、同一命令在 pwsh5 与 pwsh7 行为不一致、或需要为 pwsh7.3+ 增加参数传递适配时使用此 skill。. Pwsh is an agent skill from BiFangKNT/mtga.
How do I install Pwsh in Claude Code?
Run `npx skills add BiFangKNT/mtga --skill pwsh -a claude-code`. Or copy the skill folder (.codex/skills/pwsh in BiFangKNT/mtga) into .claude/skills/pwsh in your project. Claude Code loads it when a task matches its description.
How do I install Pwsh in Codex?
Run `npx skills add BiFangKNT/mtga --skill pwsh -a codex`. Or copy the skill folder (.codex/skills/pwsh in BiFangKNT/mtga) into .agents/skills/pwsh in your project. Codex loads it when a task matches its description.
Can I use Pwsh in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add BiFangKNT/mtga --skill pwsh -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pwsh, .gemini/skills/pwsh, .github/skills/pwsh and .opencode/skills/pwsh in your project.
What does Pwsh need to run?
SKILL.md names no scripts, command-line tools or credentials: Pwsh is instructions for the agent only.
Does Pwsh access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Pwsh safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Pwsh use?
Pwsh is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Pwsh use?
About 338 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 854 tokens, read only when the agent opens those files.
What are the alternatives to Pwsh?
Skills that share tags, products or a category with Pwsh: Pester Failure Analysis (PowerShell/PowerShell, 56k stars), Copilot Session Failure Analysis (dotnet/maui, 23k stars), Windows App SDK Issue Triage Report (microsoft/WindowsAppSDK, 4.7k stars) and Evaluate PR Tests (dotnet/maui, 23k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Pwsh?
BiFangKNT (a GitHub user) maintains it in BiFangKNT/mtga, which has 1,170 GitHub stars. The repository holds 6 skills in this directory. The repository was last updated on June 18, 2026.
