PokekYoke Mistake-Proofing your PowerShell scripts and functions
summary
Concrete Poka‑Yoke patterns for PowerShell with runnable techniques: use CmdletBinding and strong types plus validation attributes to block bad input, add argument completers and ValidateSetValueGenerator for predictive tab completion, and capture errors with a structured write‑error‑information payload so users can paste diagnostics. Regression tests and PSScriptAnalyzer run in PR pipelines prevent regressions. Code examples and module snippets live in repo jacolelops2025 (private now, planned public).
