Skill UI

This skill automates the hardening of Linux endpoints (Ubuntu, RHEL, CentOS) by implementing industry-standard security best practices guided by CIS Benchmarks. It systematically secures various layers, including filesystem permissions, network parameters (sysctl), SSH configuration, user access controls (PAM), and integrates deep auditing using auditd and OpenSCAP. It is essential for achieving compliance with standards like PCI DSS, HIPAA, and SOC 2.

This comprehensive guide details how to implement robust privileged session monitoring and recording using advanced PAM solutions like CyberArk PSM. It covers critical aspects including architecting network controls (routing all access through proxies), configuring keystroke logging and session recording for RDP/SSH, and establishing real-time monitoring rules. Essential for meeting strict compliance requirements (e.g., PCI-DSS, SOX, HIPAA) and generating non-repudiable audit trails.

Provides a detailed, multi-platform workflow to monitor long-running computational experiments. It checks the status of jobs across various environments (SSH, vast.ai, Modal), collects screen logs, fetches structured JSON results, and pulls detailed training metrics (loss curves, accuracy) from Weights & Biases (W&B). Essential for MLOps and automated result review.

This skill covers performing comprehensive vulnerability assessments across diverse environments, including on-premises infrastructure, cloud VMs, and container registries. It leverages standard network protocols like SSH (Linux) and WMI (Windows), coupled with advanced cloud provider APIs for analyzing disk snapshots without requiring local endpoint agents. Ideal for security auditing and compliance checks.

This guide details how to configure and execute deep, authenticated vulnerability scans using OpenVAS/Greenbone Vulnerability Management (GVM). By utilizing valid credentials (SSH, SMB, or ESXi), users can log into target systems to detect local vulnerabilities, missing security patches, and misconfigurations, which are typically missed by unauthenticated scans. Essential for professional security auditing and penetration testing.

This guide details how to perform authenticated (credentialed) vulnerability scans using industry-leading tools like Nessus, Qualys, and OpenVAS. By utilizing service credentials (SSH, SMB, WinRM, SNMPv3), the scan moves beyond superficial banner checks to deeply inspect installed patches, configurations, and local system settings on Linux, Windows, and network devices. This is crucial for detecting vulnerabilities that unauthenticated scans often miss, significantly improving security assessment accuracy.

Tmux is a powerful terminal multiplexer that enables users to manage multiple sessions, windows, and panes within a single terminal connection. It is essential for maintaining persistent connections on remote servers (surviving SSH disconnects), running long-term background jobs, and automating complex, multi-pane workflows directly from shell scripts, significantly enhancing remote development efficiency.

Utilize Modal, a serverless GPU cloud, for running complex machine learning workloads, including training, fine-tuning, and inference. This tool provides a zero-config environment, eliminating the need for SSH setup or Docker management. It features automatic scale-to-zero billing and local-first execution, making high-powered GPU compute accessible for debugging and small-scale experiments.

A robust orchestration skill designed for managing large-scale, complex machine learning experiments on remote GPU clusters via SSH. It handles multi-seed sweeps, sequential wave transitions, and deep learning pipelines requiring state management. Features include OOM-aware automatic retries, cleanup of stale terminal sessions, and deterministic scheduling to prevent race conditions, making it ideal for grid computing and staged training.

This guide details how to manage and structure credentials within KubeSphere DevOps using Kubernetes Secrets. It covers various types (SSH keys, basic auth, API tokens, kubeconfig) and emphasizes the critical resource structure, specific labels, and API endpoints required for integrating credentials into automated CI/CD pipelines (e.g., Jenkins, ArgoCD).

The Desktop Commander MCP grants agents deep reach across the user's entire operating environment, extending far beyond the typical IDE sandbox. Key capabilities include maintaining persistent shell sessions, managing long-running background processes, accessing arbitrary filesystems, and natively handling structured data formats (Excel, PDF, DOCX). It also enables remote operations via SSH and large-scale content search, making it ideal for complex, multi-turn development, DevOps, and data analysis workflows.

An expert playbook detailing advanced techniques for pivoting across compromised Linux hosts. Techniques cover SSH agent hijacking, credential harvesting from common system files, key extraction, and abusing internal services via D-Bus and systemd exploitation, crucial for post-exploitation stages.
