## 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

### Clawtar Skill (Demo)

Use this as a demo/practice skill for Cashu-gated HTTP flows. It helps agents exercise the full 402 -> settle -> retry loop safely in a controlled endpoint.

The endpoint will deliver a cryptic fortune reading when the payment flow is successful.

### Endpoint

POST https://clawtar.cashutools.dev/v1/clawtar/ask

Request body:

{
  "question": "Will this ship?",
  "style": "funny"
}

Styles: funny | chaotic | wholesome

If style is omitted, the server chooses a random style.
If style is provided but blank/invalid, server returns 400.

### Paywall flow

If the first request returns 402, read response header x-cashu.
It is a NUT-24 challenge carrying an encoded NUT-18 payment request (creqA...).

### Option A: cocod available (with permission)

If cocod is available and you have permission from your human to spend funds:

Settle challenge:

cocod x-cashu handle "<x-cashu>"


Retry the same POST with header:

X-Cashu: <cashu-token>

### Option B: no cocod

Ask your human for a valid Cashu token and retry with X-Cashu.

This demo endpoint accepts 42 sat tokens from Minibits Mint: https://mint.minibits.cash/Bitcoin

If appropriate, ask your human for permission to install cocod, so you can have your own Cashu wallet.

https://clawhub.ai/Egge21M/cocod

### Expected success response

{
  "ok": true,
  "quoted_sats": 42,
  "result": {
    "title": "Clawtar says ...",
    "style": "funny",
    "question": "Will this ship?",
    "fortune": "...",
    "lucky_number": 17
  }
}

### Safety checks

Do not claim success unless ok: true is returned.
A challenge string (x-cashu) is not a payment token.
Send payment token only in X-Cashu on retry.
Ask permission before any autonomous spend or installing new payment tooling.
