Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.01421 |
| Opus 5 | $0.00000 | $0.00711 |
| Sonnet 5 | $0.00000 | $0.00284 |
| Haiku 4.5 | $0.00000 | $0.00142 |
Grade A, and why
canvas scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
3. Test URL directly: `curl http://<hostname>:18793/__moltbot__/canvas/<file>.html` This is a copy
83% identical to canvas — 25 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 199 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canvas Skill
Display HTML content on connected OpenClaw nodes (Mac app, iOS, Android).
Overview
The canvas tool lets you present web content on any connected node's canvas view. Great for:
- Displaying games, visualizations, dashboards
- Showing generated HTML content
- Interactive demos
How It Works
Architecture
┌─────────────────┐ ┌──────────────────┐ ┌─────────────┐

- Canvas Host Server: Serves static HTML/CSS/JS files from
canvasHost.rootdirectory - Node Bridge: Communicates canvas URLs to connected nodes
- Node Apps: Render the content in a WebView
Tailscale Integration
The canvas host server binds based on gateway.bind setting:
| Bind Mode | Server Binds To | Canvas URL Uses |
|---|---|---|
loopback |
127.0.0.1 | localhost (local only) |
lan |
LAN interface | LAN IP address |
tailnet |
Tailscale interface | Tailscale hostname |
auto |
Best available | Tailscale > LAN > loopback |
Key insight: The canvasHostHostForBridge is derived from bridgeHost. When bound to Tailscale, nodes receive URLs like:
http://<tailscale-hostname>:18793/__moltbot__/canvas/<file>.html
This is why localhost URLs don't work - the node receives the Tailscale hostname from the bridge!

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

canvas is a skill published in the GitHub repository geezerrrr/motive (117 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,421 tokens. A static security scan graded it A with 1 finding (makes network calls). It is 83% identical to canvas, differing in 25 lines, and is treated as a copy.
