name	log-analysis
description	This skill should be used when analyzing Breenix kernel logs for debugging, testing verification, or understanding kernel behavior. Use for searching timestamped logs, finding checkpoint signals, tracing execution flow, identifying errors or panics, and extracting diagnostic information.

Kernel Log Analysis for Breenix

Search, analyze, and extract information from Breenix kernel logs for debugging and testing.

Purpose

Breenix logs all kernel runs to logs/breenix_YYYYMMDD_HHMMSS.log. This skill provides patterns for searching these logs efficiently, finding checkpoint signals, tracing execution, and diagnosing issues.

When to Use

• Finding test signals: Locate checkpoint markers like 🎯 KERNEL_POST_TESTS_COMPLETE 🎯
• Tracing execution: Follow kernel boot sequence or specific subsystem initialization
• Debugging failures: Find panics, faults, or error messages
• Verifying behavior: Confirm expected operations occurred
• Performance analysis: Check timing of operations via log timestamps
