How does this skill improve my OS development workflow?

It provides systematic diagnostic procedures and decodes cryptic error codes, reducing the time spent on low-level debugging by pinpointing issues in frame allocators, page tables, and kernel stacks.

What specific capabilities does it provide for memory errors?

It offers detailed decoding for page fault error codes, provides patterns for identifying shared page table conflicts, and implements checkpoint logging to isolate elusive memory corruption bugs.

What does the Breenix Memory Debugging skill do?

This skill equips Claude with specialized knowledge to diagnose and resolve complex memory issues in the Breenix kernel, including page faults, allocator failures, and page table conflicts.

When should I use this skill?

Activate this skill when debugging kernel-level exceptions, handling 'Out of Memory' (OOM) errors, verifying virtual memory mappings, or troubleshooting stack overflows in Breenix.

Can it help with Rust-specific memory issues in Breenix?

Yes, it includes specialized guidance for Breenix's Rust-based subsystems, such as the global heap allocator, frame allocation logic, and kernel stack layout.

セキュリティとテスト

Diagnoses and resolves complex kernel memory issues including page faults, double faults, and allocator failures within the Breenix operating system.

概要

This skill provides a systematic framework for debugging intricate memory-related bugs in kernel development. It guides users through the intricacies of Breenix memory subsystems—physical frame allocation, virtual page tables, heap management, and kernel stacks—offering specific diagnostic patterns for common errors like page faults and double faults. By integrating checkpoint logging and state verification, it helps developers isolate failures in the memory management lifecycle, ensuring stable kernel-space and user-space transitions.
