Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00025 | $0.00308 |
| Opus 5 | $0.00013 | $0.00154 |
| Sonnet 5 | $0.00005 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
17-canvas-first scanned grade A with 0 findings 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 7d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Canvas-first (entregas visuales)
Usá canvas (Cursor .canvas.tsx, o artifact equivalente del IDE) para artefactos analíticos grandes — no para cada respuesta estructurada.
Cuándo usar canvas
- Auditorías, métricas, billing, comparativas con tablas o charts.
- Planes de
/orquestaro roadmaps con muchas fases. - Propuestas A/B con trade-offs extensos.
- Señal: vas a poner 2+ tablas o 4+ secciones con headers en el chat.
Cuándo NO
- Fixes de código, diffs, preguntas cortas, validación no-cómplice.
- Entregables canónicos que viven en
docs/o PR.
Cursor
Leer ~/.cursor/skills-cursor/canvas/SKILL.md antes de escribir .canvas.tsx. Ubicación: canvases/ del workspace Cursor. Chat: 2–5 líneas + link al canvas.
Fallback
Sin canvas: markdown liviano (máx. 1 tabla, headers solo si 3+ secciones).
Delegación
Si el subagente entrega análisis grande y hay canvas: pedir .canvas.tsx (Cursor) o artifact nativo; chat solo resumen.
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.
