Skill UI

Optimize Linux system performance by configuring kernel parameters, analyzing bottlenecks, and tuning resources like memory, CPU, and network. Includes monitoring tools and sysctl settings for production environments.

This skill provides expertise in writing strict POSIX-compliant shell scripts for maximum portability across Unix-like systems. It focuses on shell-agnostic scripting compatible with dash, ash, sh, and bash in POSIX mode. Key areas include defensive programming, portable error handling, safe argument parsing, and cross-platform compatibility. It ensures scripts run on Linux, BSD, Solaris, AIX, and macOS without relying on GNU-specific features or bash extensions.

Provides comprehensive techniques for escalating privileges from low-privileged users to root or administrator on Linux and Windows systems, covering sudo, cron, capabilities, token impersonation, and Active Directory attacks for authorized penetration testing.

A workflow for converting known binary vulnerabilities into working exploits. Covers stack/heap/kernel pwn techniques using pwntools, libc-database, and ROP. Suitable for porting CTF solutions to authorized remote targets or developing RCE payloads for Linux kernel drivers.

Create, manage and monitor systemd services and timer units on Linux. Covers unit file authoring, dependencies, socket activation, resource limits, security hardening, journalctl logs and production service debugging.

Comprehensive guide for managing users, groups, permissions, sudo access, and LDAP integration on Linux systems. Includes practical scripts for bulk user operations and access auditing. Ideal for system administrators and DevOps engineers.

Provides step-by-step guidance for deploying the Categraf collector on Linux, Docker, Windows, and Kubernetes. Covers installation, config.toml writers and heartbeat setup, systemd service registration, and verification commands.

Create and manage monitoring alert rules for systems like Prometheus, MySQL, and Linux. Prefer importing validated integration templates before writing custom rules. Supports bulk imports or single metric alerts. Helps configure CPU, memory, and database alerts efficiently within Nightingale.

Guides creation of Nightingale (N9E) monitoring dashboards: prefer importing validated integration templates for Linux, MySQL, Redis, Kafka and more, or build custom panels with PromQL only.

CLI that lets AI agents observe and operate desktop GUIs on macOS, Windows and Linux via native accessibility trees: snapshot UI state, click, type, fill forms, navigate menus, manage windows and take screenshots.

This guide covers the agent-desktop CLI for Linux desktop automation. It details command capabilities on X11 and Wayland, including observation, surface interaction, window control, and capture. It explains AT-SPI accessibility requirements, troubleshooting for GNOME, and specific limitations for pointer gestures and clipboard operations. Essential for automating GUI tasks on Linux systems.
