Triage and resolve Fedora issues with dnf, systemd, and SELinux-aware guidance.
Triage and resolve Debian Linux issues with apt, systemd, and AppArmor-aware guidance.
Triage and resolve Arch Linux issues with pacman, systemd, and rolling-release best practices.
Use this skill when managing Linux servers, writing shell scripts, configuring systemd services, debugging networking, or hardening security. Triggers on bash scripting, systemd units, iptables, firewall, SSH configuration, file permissions, process management, cron jobs, disk management, and any task requiring Linux system administration.
Use the local `5dive` CLI on a 5dive runtime VM to spawn, inspect, send to, and tear down sibling agents. Trigger this skill whenever the user asks for a worker, sub-agent, side task, parallel run, "another agent", "fan out", "delegate", or anything that needs more than one Claude/Codex/Gemini process running at once on the host. Also trigger when the user asks to inspect, restart, or pair an existing agent, when they mention `/var/lib/5dive/`, or when they need a machine-readable health check (`5dive doctor --json`). Always prefer `5dive` over running coding CLIs by hand — it is the only sanctioned way to keep agents under systemd.
Create and harden systemd service unit files following modern best practices. Use when writing new systemd units for web applications, background workers, or daemons, or when hardening existing services with security sandboxing and isolation features. Covers service types, dependencies, restart policies, security options, and filesystem restrictions.
· Administer Debian/Ubuntu/Mint/Pop: apt, dpkg, PPAs, snaps, systemd, GRUB, HWE, desktop. Triggers: 'debian', 'ubuntu', 'mint', 'popos', 'apt', 'dpkg', 'ppa'. Not for Arch/Fedora/NixOS.
Manage Linux systems covering systemd services, process management, filesystems, networking, performance tuning, and troubleshooting. Use when deploying applications, optimizing server performance, diagnosing production issues, or managing users and security on Linux servers.
Concurrency safety patterns for distributed pueue + mise + systemd-run job pipelines. TRIGGERS - queue pueue jobs, deploy to remote host, concurrent job collisions, checkpoint races, resource guards, cgroup memory limits, systemd-run, autoscale, batch processing safety, job parameter isolation.
Create and manage systemd services and timers. Configure service dependencies and resource limits. Use when managing system services.
Linux server administration expert. Ubuntu/Debian, Nginx, Apache, SSL, firewall, systemd, server hardening. Use for server setup and config.
Linux (Ubuntu/Debian) server initial setup and ongoing administration skill. Covers new server hardening, user management, package management, file permissions, resource limits, log rotation, cron scheduling, and disk management. USE WHEN: - Performing initial setup of a fresh Ubuntu/Debian server (VPS, bare metal, cloud VM) - Hardening SSH, disabling root login, configuring sudo - Configuring system-level resource limits (ulimits, sysctl) for high-concurrency workloads - Managing users, groups, file permissions, and ACLs - Setting up log rotation, journald retention, swap, and NTP - Troubleshooting disk full, FD exhaustion, locale errors, or time drift DO NOT USE FOR: - Container-level administration (use docker or kubernetes skill) - Application deployment pipelines (use deployment-strategies or ci-cd skill) - Firewall/fail2ban configuration (use firewall skill) - Nginx or service configuration (use nginx or systemd skill)
