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 | $0.00053 | $0.05386 |
| Opus 5 | $0.00026 | $0.02693 |
| Sonnet 5 | $0.00011 | $0.01077 |
| Haiku 4.5 | $0.00005 | $0.00539 |
Grade A, and why
canvas-actions 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Agent Canvas
Create visual, interactive HTML pages that users see in the AI Maestro dashboard. Embed live data, receive structured actions when users interact, and update pages in response.
When to use this skill
Use canvas whenever the output is better experienced visually than as terminal text.
Proactive triggers -- create a canvas when:
- User asks to see data visually: "show me", "display", "visualize", "report on", "dashboard for", "chart of", "table of", "summary of"
- User asks for a form or config UI: "let me configure", "settings for", "create a form", "let me pick", "I want to choose"
- User asks for an approval or review flow: "let me approve", "review these", "I need to decide", "show me the options"
- User asks you to build something interactive: "build me a", "create a page", "make a UI", "wizard for", "control panel"
- Your output has structured data: test results, API responses, file listings, metrics, logs, comparisons -- anything that would benefit from sorting, filtering, or visual hierarchy
- Your output has actions the user should take: approve/reject, select from options, configure settings, trigger operations
- You are presenting a status or progress report: build status, deployment state, system health, task progress
Do NOT use canvas for:
- Quick one-line answers
- Code that should go in a file
- Terminal commands the user should run
- Simple text responses
Default behavior: When in doubt, create a canvas. A visual, interactive page is almost always more useful than a wall of terminal text. The user can always read it in the Canvas tab of the dashboard.
Architecture: Data-Driven Interactive Pages
CRITICAL: Canvas pages must be data-driven, not static HTML.
Never hardcode data into HTML elements. Always embed data as JSON in a <script> block and render it with JavaScript. This makes pages interactive (sortable, filterable, searchable) instead of dead static text.
The pattern: Embedded JSON + JS rendering
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-actions is a skill published in the GitHub repository 23blocks-OS/ai-maestro-plugins (9 stars, last pushed 5d ago), licensed MIT. It adds 53 tokens to every session and 5,386 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
