Individual skill
kernel-debugging-advanced
Use when tracing kernel functions with ftrace or trace-cmd, profiling with perf, kprobes, or dyndbg, or analyzing a vmcore with crash. Not for QEMU GDB stubs: use qemu-for-kernel-development.

# Advanced kernel debugging
## Contract
| Field | Bound contract |
|---|---|
| Trigger | Production-grade kernel tracing and post-mortem work: ftrace function graph, `trace-cmd`, kernel `perf` probes, dynamic `kprobes`, `dyndbg`, breaking into kgdb/kdb, or analyzing a vmcore after a panic. |
| Authority | Read-only. Writes nothing. Chat output only. No remote mutation. |
| Side effect | Returns commands and analysis procedures the caller runs on their target. No source files are modified. |
| Done | The trace, probe, or vmcore analysis plan is delivered with the config and mount prerequisites named. |
## Inputs
1. Symptom (required): the latency spike, wrong behavior, or panic to explain.
