Quick Review

Well-structured reference for PowerShell pitfalls with excellent comparative tables showing wrong vs. correct patterns. The skill provides strong task knowledge through actionable examples covering operators, Unicode restrictions, null checks, error handling, and JSON operations. Description is adequate but could be more specific about what types of tasks this skill helps with (e.g., 'scripting', 'debugging', 'file operations'). Novelty is moderate—while the content is valuable for avoiding common mistakes, much of it represents documentation consolidation rather than complex procedural knowledge. The tabular format and critical warnings make it immediately actionable for a CLI agent. Structure is clean with numbered sections and a useful script template. Minor improvement needed: the description could better convey the skill's breadth (covers 10 distinct pattern categories).
