Automated summary

Runs a full health audit of the newna.ai VPS, checking PM2, Docker, nginx, SSL, databases, disk, memory, firewall, Fail2ban, systemd, and backups.

Strengths

  • Comprehensive coverage of server infrastructure across 11 categories.
  • Proactive warning thresholds (e.g., SSL expiry, disk usage).
  • Report structured by severity for quick triage.

Limitations

  • Tied to the newna.ai VPS; not a generic server health check.
  • Requires a dedicated health-agent to be spawned.
  • Does not include application-level logs or custom business metrics.
When to use it

Use this skill for a quick server health overview or when investigating performance issues or errors.

When not to use it

Do not use for configuration changes, deployments, or on servers other than newna.ai.

Security analysis

Caution
Quality score88/100

The skill performs read-only health checks using Bash, which is necessary for its purpose but poses risk if the spawned health-agent executes unintended commands. The described actions are legitimate and non-destructive.

Findings
  • •Requires Bash access with potential elevated privileges for checking system services and firewall.
  • •Interacts with critical services (PM2, Docker, nginx) which, if mishandled, could cause disruption.
How this analysis is made

Examples

Basic health check
Check server health on newna.ai.
Investigating slow responses
Is the server ok? It's been slow lately. Run a full health check.
Proactive audit
Run server status and tell me if anything is wrong.

name: server-health description: Comprehensive health check of the newna.ai VPS. Checks PM2, Docker, nginx, SSL, databases, disk, firewall, backups, and system resources. Use when the user says "check server health", "is the server ok", "server status", "what's running", "health check", or invokes /server-health. Also use proactively when something seems wrong (high restart counts, errors, slow responses). allowed-tools: [Bash, Read, Grep, Agent]

/server-health

Run a full health audit of the newna.ai VPS by spawning the health-agent.

What it checks

  1. PM2 — process status, restart counts, memory usage
  2. Docker — container health (deploy-api-1, gitea, filebrowser, portainer)
  3. Nginx — config validity, service status
  4. SSL — certificate expiry (warns at 30 days)
  5. Databases — SQLite integrity, WAL sizes (admin.db, chat.db)
  6. Disk — partition usage (warns at 80%)
  7. Memory — available RAM (warns below 1GB)
  8. Firewall — UFW status, expected ports
  9. Fail2ban — SSH jail status, banned IPs
  10. Systemd — failed units, backup timer status
  11. Backups — last backup run, any errors

Spawn the health-agent and present its report organized by severity.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/server-health-mryiqgrb/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/server-health-mryiqgrb' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/server-health-mryiqgrb/download' --output '.skill-downloads/server-health-mryiqgrb/SKILL.md.part' && mv '.skill-downloads/server-health-mryiqgrb/SKILL.md.part' '.skill-downloads/server-health-mryiqgrb/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/server-health-mryiqgrb/SKILL.md' && test -s '.skill-downloads/server-health-mryiqgrb/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/server-health' && cp -R '.skill-downloads/server-health-mryiqgrb' '.claude/skills/server-health'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/server-health-mryiqgrb'

openskills read 'server-health-mryiqgrb'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/server-health-mryiqgrb/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
