Design Canvas

design/canvas — skill payload

Machine-readable contract: ../canvas-design.manifest.json.

What this skill does

Renders a one-canvas visual (poster, social card, hero image, conference slide) from a structured brief: background colour or image, headline, body copy, optional imagery placement, palette. Emits SVG (source) and PNG (preview).

When to use it

• You need a single graphic — a launch announcement, an internal poster, a social card.
• The brief is closed (you know the copy and rough layout); you want consistent output without designer time.

When not to use it

• The output is a multi-slide deck — use office/pptx-toolkit.
• The output is a brand system (logo, typeface, full guidelines) — this is a render, not a brand exercise.
• The visual needs to be editable in Figma — emit a frontend-design React preview or hand off to a designer.

Determinism and risk

Determinism: medium — small style variations are possible. Risk: low — visual output only.

How it composes

Often downstream of design/theme-factory (uses its palette + type scale) and content/research-writer (uses its headline / body copy).
