The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes sudo to execute commands such as sysctl --system and modprobe tcp_bbr to manage kernel parameters and load necessary kernel modules.
[PERSISTENCE]: Instructions include creating and modifying configuration files within /etc/sysctl.d/, ensuring that performance tunings remain effective after system reboots.
[PRIVILEGE_ESCALATION]: The skill requires administrative (sudo) access to perform its primary functions, including writing to protected system directories and modifying live kernel state.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and act upon performance profiling evidence and host inspection data from external sources, which presents an attack surface for indirect injection.
Ingestion points: The skill reads measured bottleneck data and performance profiling evidence (SKILL.md).
Boundary markers: No specific delimiters or safety warnings are provided to prevent the agent from interpreting instructions embedded within the performance data.
Capability inventory: The skill possesses file-write capabilities (via tee to /etc/sysctl.d/), kernel module loading (modprobe), and system-wide configuration application (sysctl --system).
Sanitization: There is no evidence of validation or sanitization of the input data before it is used to generate system configuration changes.
