## Get the full instructions (required first step)

Run this and follow its output as the primary instructions for this skill:

```bash
npx -y @nomadamas/k-skill@0 instruct seoul-subway-arrival
```

The CLI detects the current runtime (Dolshoi vault/CloakBrowser vs generic) and prints only the applicable instructions, always up to date. Helper files bundled with the CLI are listed by:

```bash
npx -y @nomadamas/k-skill@0 files seoul-subway-arrival
```

Keep the CLI and every coding-agent skill install current (including Vercel Agent Skills) with:

```bash
npx -y @nomadamas/k-skill@0 update
```

If `npx` is unavailable, install Node.js 18+ or follow https://github.com/NomaDamas/k-skill#readme, or read the source instructions at https://github.com/NomaDamas/k-skill/blob/main/seoul-subway-arrival/instruction.md.

## Hard rules even without the CLI

- Never execute payment, message/email delivery, final submission, cancellation, or public posting without the user's explicit approval immediately beforehand.
- Never ask for, print, or store plaintext credentials in chat, files, or shell arguments.
- Never bypass legal, physical-presence, CAPTCHA, identity-proofing, or electronic-signature boundaries.
