Server Ops Troubleshooter
Example session with this skill installed
My docker container keeps crashing with an exit code 137 on the production server. I need to find out why and fix it.
- Read your context and instructions
- Compiled the server ops troubleshooter
🔍 Diagnosis
The container is likely being terminated by the Linux Out-Of-Memory (OOM) killer.
📋 Diagnostic commands
docker inspect <container_id> --format='{{.State.OomKilled}}'
dmesg | grep -i "oom-killer"
free -h
🛠️ Remediation
[Production] 1. Limit container memory in docker-compose.yml:
deploy:
resources:
limits:
memory: 512M
- Restart service...

About this skill
The problem
Server failures and Docker deployment errors often lead to hours of "guess-and-check" troubleshooting. Blindly running remediation commands on production systems risks data loss and extended downtime.
What it does
- Executes a systematic 6-step diagnostic workflow to find the root cause before suggesting fixes.
- Generates copy-pasteable bash commands for Docker logs, system resource checks, and container status.
- Provides specialized remediation for Java JAR boot failures, PostgreSQL connection errors, and Jenkins pipeline blocks.
- Calculates risk levels and enforces mandatory warnings for destructive actions like volume deletion or service restarts.
- Automates remote server inspection using Python-based SSH clients when local tools are unavailable.
Frameworks & tools
Docker, Linux (Ubuntu/Debian/CentOS), Java (Spring Boot/JAR), PostgreSQL, Jenkins, and Paramiko for SSH automation.
Why this beats prompting it yourself
Standard LLMs often suggest dangerous commands without checking your environment first. This skill enforces a "diagnose-first" posture, distinguishes between local and production contexts, and includes a pre-built library of verified sysadmin commands that prevent common operator errors.
Use cases
- Troubleshooting "OOMKilled" or "Exit 137" errors in Docker containers.
- Fixing "Connection Refused" errors between application services and databases.
- Resolving disk-full or permission-denied issues on Linux production servers.
- Debugging failed Jenkins builds or Docker-in-Docker socket mounting issues.
Known limitations
Standard SSH binaries may require a custom Python script for non-interactive password authentication on Windows hosts.
