The Agent Skills Directory

[SAFE]: The skill serves as a technical debugging guide for SGLang distributed inference, providing actionable instructions for identifying and resolving deadlocks in multi-GPU environments.
[COMMAND_EXECUTION]: Includes standard command-line instructions for system diagnostics, such as using py-spy, cuda-gdb, grep, and diff. These commands are standard for the described debugging workflow and do not exhibit malicious intent.
[EXTERNAL_DOWNLOADS]: Mentions pip install py-spy. py-spy is a well-known, legitimate sampling profiler for Python programs. Following the trusted source guidance, this is documented neutrally as a standard prerequisite for the task.
[PRIVILEGE_ESCALATION]: Notes that py-spy requires root or CAP_SYS_PTRACE to attach to running processes. This is a factual statement regarding the tool's operational requirements for process inspection and does not constitute a malicious attempt to acquire unauthorized permissions.
[DATA_EXFILTRATION]: Recommends implementing per-rank logging to the local /tmp directory and hashing tensors with hashlib.md5 to facilitate comparison. These are standard debugging practices to ensure data consistency across distributed nodes and do not involve transmitting data to external or untrusted destinations.
