linux-agent-skills

Router and index for the Linux/DevOps agent skill library. Load this skill first to find which specialized skill to load. Covers: Linux sysadmin (files, processes, networking, shell, users), Docker (containers, images, compose, Dockerfile), Kubernetes (kubectl, deployments, Helm, ingress, secrets), security (firewall, hardening, SSL/TLS, audit), DevOps (Ansible, Terraform, CI/CD, monitoring, Git), databases (MySQL, PostgreSQL, Redis, MongoDB, Elasticsearch, SQL optimization), backup & recovery (rsync, snapshot, disaster-recovery, cloud-backup), networking (DNS, VPN, load-balancer, proxy, TCP/IP, traffic-analysis), performance (tuning, profiling, benchmarking), server management (Nginx, Apache, systemd, cron, SSH, log-analysis), cloud CLI (AWS, Azure, GCloud, Aliyun). Use when user asks about any infrastructure, server, container, or DevOps task.

description

Router and index for the Linux/DevOps agent skill library. Load this skill first to find which specialized skill to load. Covers: Linux sysadmin (files, processes, networking, shell, users), Docker (containers, images, compose, Dockerfile), Kubernetes (kubectl, deployments, Helm, ingress, secrets), security (firewall, hardening, SSL/TLS, audit), DevOps (Ansible, Terraform, CI/CD, monitoring, Git), databases (MySQL, PostgreSQL, Redis, MongoDB, Elasticsearch, SQL optimization), backup & recovery (rsync, snapshot, disaster-recovery, cloud-backup), networking (DNS, VPN, load-balancer, proxy, TCP/IP, traffic-analysis), performance (tuning, profiling, benchmarking), server management (Nginx, Apache, systemd, cron, SSH, log-analysis), cloud CLI (AWS, Azure, GCloud, Aliyun). Use when user asks about any infrastructure, server, container, or DevOps task.

Linux Agent Skills — Router

This is the first-layer router. Read this file, then load the single most relevant skill path before acting.

How to Load a Skill

Match the user's task to a skill path in the tables below.
Read that SKILL.md file into context.
Follow its instructions.

Do not load more than 2 skills at once unless the task explicitly spans two platforms (e.g., database backup requires both database/<engine> + backup/<method>).

General Q&A (Fallback)

Task / Keywords	Skill Path
Conceptual questions, multi-topic sysadmin Q&A, no clear platform match	`skills/sysadmin-qa/SKILL.md`

Precedence Rules

When keywords overlap, apply these rules in order:

Explicit platform wins — if the user names a specific tool (e.g., nginx, mysql, kubectl, terraform), load that tool's skill directly.
Container > OS — if both Docker/K8s and Linux keywords appear, prefer the container skill; only load linux/network-tools if the issue is on the host network.
Platform-specific troubleshooting — prefer kubernetes/troubleshooting for K8s issues and performance/troubleshooting for OS-level performance issues; don't default to sysadmin-qa.
TLS in K8s context → kubernetes/service-ingress first, then security/ssl-tls if certificate management is needed.
Database backup → load the database skill (database/<engine>) AND the backup skill (backup/<method>) together.
Networking overlap — use context to disambiguate: "Docker network" → docker/networking; "host firewall" → security/firewall; "DNS setup" → network/dns; "K8s service expose" → kubernetes/service-ingress.
sysadmin-qa is the last resort — only use when no specific skill matches and the question is conceptual or spans more than 3 categories.
