How do I install the Powershell Windows skill?

Run npx skillmds@latest add comol/powershell-windows in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Powershell Windows safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Powershell Windows?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Powershell Windows free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

PowerShell Windows — Scripting Rules

Core Principles

1. Command Separation

Windows PowerShell 5.1 does not support &&; PowerShell 7 does.
For independent commands use ;: Set-Location "path"; Get-ChildItem.
For dependent native commands preserve short-circuit semantics explicitly:
```
git add .
if ($LASTEXITCODE -eq 0) { git commit -m "message" }
```

2. Path Quoting

Always use double quotes for paths with spaces:
```
cd "D:\My Projects\MyApp"
```

3. Script Execution

For .bat/.cmd files:

./gradlew clean build
.\gradlew.bat clean build

4. Docker Commands

Specify full path to docker-compose files:

docker-compose -f "D:\My Projects\app\docker-compose.yml" up -d

5. HTTP Requests

Prefer PowerShell-native HTTP so behavior does not depend on whether curl resolves to an alias or curl.exe:
```
Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
```

6. Waiting/Delays

Wrong: timeout 10
Correct:
```
Start-Sleep -Seconds 10
```

7. JSON Handling

JSON parsing:

$response = Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
$json = $response.Content | ConvertFrom-Json
$json | ConvertTo-Json -Depth 3

8. Process Checking

Process search:

Get-Process -Name "java" -ErrorAction SilentlyContinue

9. Docker Operations

Stop containers:

docker-compose -f "path\to\file.yml" down

Build images:

docker-compose -f "path\to\file.yml" build --no-cache

10. Error Handling

Ignore errors:

Get-Process -Name "java" -ErrorAction SilentlyContinue

Common Errors and Fixes

Error	Cause	Fix
`&& is not recognized`	Running Windows PowerShell 5.1	Use `;` only for independent commands; use `$LASTEXITCODE` for conditional chaining
`curl` behaves unexpectedly	Windows PowerShell alias / executable resolution differs	Use `Invoke-WebRequest`, or call `curl.exe` explicitly when its CLI semantics are required
`timeout` behaves unexpectedly	Console utility semantics differ from shell sleep	Use `Start-Sleep`
`Path not found`	Missing quotes on spaced path	Wrap path in double quotes

Correct Command Examples

# Change directory and execute command
cd "D:\My Projects\MyApp"; ./gradlew clean build -x test

# Wait and make HTTP request
Start-Sleep -Seconds 10; Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing

# Docker operations
docker-compose -f "D:\My Projects\MyApp\docker-compose.yml" down
docker-compose -f "D:\My Projects\MyApp\docker-compose.yml" build --no-cache
docker-compose -f "D:\My Projects\MyApp\docker-compose.yml" up -d

# Check server status
$response = Invoke-WebRequest -Uri "http://localhost:9090/status" -UseBasicParsing
$json = $response.Content | ConvertFrom-Json
Write-Host "Transport: $($json.mcp.transport)"
