## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Port Check Skill

Quickly verify if services are up and responding on specific ports.

### Usage

# Basic TCP check
bash scripts/port-check.sh localhost:8080 localhost:5432

# Multiple targets with HTTP status check
bash scripts/port-check.sh localhost:80 api.example.com:443 --http

# Custom timeout (default 3s)
bash scripts/port-check.sh 192.168.1.1:22 --timeout 5

### Output

✅ host:port — open (TCP connected)
✅ host:port — open (HTTP 200) (with --http flag)
⚠️ host:port — open but HTTP 500 (port open, bad HTTP status)
❌ host:port — closed/timeout (no response)

### Exit Codes

0 — all targets up
1 — one or more targets down

### Common Checks

# OpenClaw gateway
bash scripts/port-check.sh localhost:18789 --http

# Database + web stack
bash scripts/port-check.sh localhost:5432 localhost:6379 localhost:3000

# Home network devices
bash scripts/port-check.sh 192.168.1.1:80 192.168.1.50:22 --timeout 2
