template-render

The standard recipe for producing a deliverable from a Template and a Style.

Procedure

1. Pick a Template:
   • If the user names a category ("a poster", "a card"), list candidates: claw template list --category <cat>.
   • If they describe a use-case, match by tags or name.
2. Pick a Style:
   • If they reference a brand or saved style, use that.
   • Otherwise default to the workspace's primary Style (often the first non-builtin or claw).
3. Compose data:
   • Read the template's slots from claw template get <id>.
   • For each slot, write a JSON field with id as the key.
   • Respect maxLength, maxItems, required.
4. Render:

   claw template render <templateId> --style <styleId> --data data.json --format pdf,png --out ./deliverable
   

5. Report back: the paths produced and a sentence describing what is in each.

Formats

Format	Renderer	Notes
html	direct	Canonical, fastest, no deps.
svg	wraps html in <foreignObject>	Use for scalable vector.
pdf	Playwright (Chromium)	Falls back to a minimal Node PDF if Playwright is unavailable.
png	Playwright (Chromium)	2x deviceScaleFactor.
pptx	OpenXML (Node only)	Minimal one-slide PPTX. Best for presentation category.

Constraints

• Never hard-code style values into the data. The Style is the source of truth for color and typography.
• If the template declares outputs and the requested format is not in the list, fail with a clear error.
• Generated outputs go under .claw/templates/<templateId>/outputs/ unless --out is specified.
