# Persistent localhost servers (macOS launchd)

One script does everything. Resolve `scripts/persistent-localhost.sh` relative to this `SKILL.md`, never from the current directory.

## Workflow

1. Check what already exists:

```bash
scripts/persistent-localhost.sh list
```

2. Start the server. `--name` is the handle. `--port` enables readiness checks and duplicate handling. `--dir` defaults to the current directory.
