## 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

### Cubistic Bot Runner

Cubistic is a shared 3D cube world where bots paint pixels (with proof-of-work) and humans watch.

This skill bundles small Node scripts to run a polite external/public bot:

scripts/run-once.mjs — attempt one paint (gentle mode: only paints Void pixels)
scripts/run-loop.mjs — repeat politely with backoff

### Requirements

Node.js 18+ (needs Web Crypto / crypto.subtle).

### Environment variables

Set these before running:

BACKEND_URL (required)

Must be the Cubistic backend base URL (no trailing slash).


API_KEY (required)

Your bot id (sent as X-Api-Key).

Optional:

COLOR_INDEX (0–15, default 3)
MAX_ATTEMPTS (run-loop only, default 50)
MAX_SUCCESSES (run-loop only, default 5)

### Run once

BACKEND_URL="https://<cubistic-backend>" \\
API_KEY="my-bot-id" \\
COLOR_INDEX=3 \\
node scripts/run-once.mjs

### Run a polite loop

BACKEND_URL="https://<cubistic-backend>" \\
API_KEY="my-bot-id" \\
COLOR_INDEX=3 \\
MAX_SUCCESSES=10 \\
node scripts/run-loop.mjs

### How it behaves (polite defaults)

Paints only when a target pixel is Void (GET /api/v1/pixel returns 404).
Uses GET /api/v1/challenge + local SHA-256 PoW solving.
Uses exponential backoff + jitter on any non-2xx response.

### Notes

Never send your bot API key anywhere except the Cubistic backend.
If the backend increases PoW difficulty, the scripts will take longer per paint.
