PowerShell Development Skill

Conventions and safety patterns for PowerShell scripts in scripts/ and CI.

Style and Linting

• Use pwsh/PowerShell Core syntax where possible and Set-StrictMode -Version Latest.
• Use Write-Host sparingly; prefer Write-Output and Write-Error for correct streams.
• Use -ErrorAction Stop in helper functions when errors should abort execution.
• No Unicode icons or emojis in output messages (e.g., ✓, ✗, ⚠, 🔧). Use plain ASCII text like [OK], [FAIL], [WARN], ERROR: instead. Unicode causes encoding issues in CI logs.

Security

• Avoid embedding secrets in scripts; read from env vars and prefer platform secret stores.
• Do not commit credential tokens in any scripts or docs.

Testing and Execution

• Use pwsh -NoProfile -ExecutionPolicy Bypass -File in CI wrappers.
