Conversational GDB debugging for Breenix kernel. Use for interactive debugging sessions - set breakpoints, inspect registers, examine memory, step through code, investigate crashes.
This skill should be used when analyzing failed GitHub Actions CI/CD runs for Breenix kernel development. Use for diagnosing test failures, parsing QEMU logs, identifying kernel panics or faults, understanding timeout issues, and determining root causes of CI failures.
This skill should be used when creating or improving GitHub Actions CI/CD workflows for Breenix kernel development. Use for authoring new test workflows, optimizing existing CI pipelines, adding new test types, fixing workflow configuration issues, or adapting workflows for new kernel features.
This skill should be used when creating new integration tests for Breenix kernel features. Use for writing shared QEMU tests with checkpoint signals, creating xtask test commands, adding test workflows, and following Breenix testing patterns.
This skill should be used when migrating features from src.legacy/ to the new kernel implementation or removing legacy code after reaching feature parity. Use for systematic legacy code removal, updating FEATURE_COMPARISON.md, verifying feature equivalence, and ensuring safe code retirement.
OS kernel research specialist. Use when researching operating system best practices, comparing implementations to Linux/FreeBSD/XNU, evaluating kernel design patterns, or ensuring Breenix follows production kernel conventions.
Enforce pristine interrupt/syscall paths with no logging, diagnostics, or heavy operations. Use when developing interrupt handlers, syscall entry/exit, context switches, or timer code.
Use when debugging the Breenix kernel at assembly or C-level using GDB - investigating CPU exceptions, page faults, triple faults, examining register state during interrupt handling, stepping through boot sequence, analyzing syscall entry/exit paths, debugging context switches, or inspecting memory layout and page tables.
