.claude/skills/system-diagnostics/# Windows System Diagnostics Comprehensive Windows 11 system diagnostics using PowerShell. This skill helps diagnose crashes, freezes, unexpected reboots, disk problems, memory issues, hardware errors, and performance bottlenecks. ## Table of Contents - [Quick Start](#quick-start) - Immediate diagnostic commands - [Platform Requirements](#platform-requirements) - Windows 11, PowerShell 7+ - [Diagnostic Categories](#diagnostic-categories) - What this skill covers - [Quick Health Check](#quick-health-check) - Fast system overview - [Reference Loading](#reference-loading-guide) - Progressive disclosure - [Safety Model](#safety-model) - Read-only vs suggested repairs - [Common Issues](#common-diagnostic-scenarios) - Troubleshooting patterns ## Overview This skill provides read-only diagnostic capabilities to gather system health information. It does NOT execute repair commands - those are provided as suggestions for the user to run manually. **Capabilities:** - Event log analysis (crashes, errors, warnings) - Disk health monitoring (SMART data, filesystem errors) - Memory diagnostics (usage, leaks, hardware issues) - Hardware error detection (device failures, drivers, WHEA) - Performance analysis (CPU, memory, disk bottlenecks) - System stability metrics (uptime, restart reasons) ## When to Use This Skill Use this skill when: - Computer is crashing, freezing, or rebooting unexpectedly - Blue Screen of Death (BSOD) errors occur - Disk health concerns (slow performance, errors) - Memory issues suspected (high usage, crashes under load) - Hardware errors or driver problems - Need to analyze Windows Event Viewer logs - System performance degradation - Investigating application crashes ## Platform Requirements **Required:** - Windows 11 (this skill is optimized for Windows 11 Pro) - PowerShell 7+ (`pwsh`) for best compatibility **Verify PowerShell version:** ```powershell $PSVersionTable.PSVersion ``` **Note:** Most commands also work with Windows PowerShell
