Vela Slides

Vela Slides

Senior presentation designer. Assertion headlines, varied block types, grouped sections, brand-consistent palettes.

Fast Paths

vela server start <folder-or-file> [--port 3030]      # local preview
vela deck ship <deck.json> --output <name.jsx>       # ship existing
vela deck ship --sample --output <name.jsx>           # ship starter deck
vela deck ship --demo --output <name.jsx>             # ship demo deck (all block types)
vela deck extract <source.jsx> <output.json>          # extract from .jsx

When user asks to "load the demo deck", "show the demo", or "show me what Vela can do": use --demo. Do NOT generate a new deck. python3 skills/vela-slides/scripts/vela.py <resource> <action> [args...]

Deck DSL (compact — the ONLY format you write)

Minified, one line. NEVER use "type", "text", "deckTitle", "lanes", "slides", "blocks".

{"n":"Title","C":{palette},"T":{themes},"G":[sections]}

C — Colors used 2+ times as $A-$Z. Frequency order. Hex 6 or 8 chars. T — "d":dark {"b":"#0A0F1C","c":"#E6F1FF","a":"$A","p":"60px 72px"}, "a":alt different shade. Alternate d/a. G — Sections (USE FOR ALL DECKS): [{"g":"Name","S":[slides]}]. 3-5 narrative sections. Slide — {"t":"d","n":"Assertion Headline","d":60,"B":[blocks]}. Cover/CTA: bgGradient,align:"center",verticalAlign:"center". Duration: cover 20, content 60-90, CTA 25. Spacers: bare int.

Keys: _(type) x(text) s(size) c(color) i(icon) b(bg) w(weight) ic(iconColor) ib(iconBg) I(items) g(gap) lb(label) v(variant) H(headers) R(rows) Q(quadrants) val(value) dl(dividerLabel) cl(centerLabel) dr(drop) cp(copy) rv(reveal) hr(href) dw(download) ext(external) lv(level) tm(time) sk(skills) fi(files) desc(description) cd(code)

Study Notes (offline)

Any slide can carry a studyNotes object that renders in the 🎓 student panel with zero API calls. Mirrors the live Vera Teacher output shape so existing renderers are reused. Compact key: sN.

"sN": {
  "text": "Markdown with **bold**, *italic*, [external](https://…), and [X-Ray term](#agent).",
  "diagram": "<svg viewBox='0 0 320 140'>…</svg>",
  "questions": ["What is X?", "How does Y relate to Z?"],
  "glossary": { "agent": { "definition": "A goal-driven loop that plans, acts, observes.", "url": "https://…" } }
}

• text required; everything else optional.
• Inline [label](https://…) renders as a sanitized external link (http/https/mailto only).
• Inline [label](#term) looks up glossary[term] (lowercased) and shows a Kindle-style X-Ray popover with the definition + optional "Learn more" link.
• When an API is reachable, authored questions become clickable Vera prompts + an Ask input appears. Offline, they render as static "QUESTIONS TO PONDER" bullets.
• Slides carrying studyNotes show a 🎓 marker in the TOC, gallery thumbnails, and slide viewer.
• Size limits: text ≤ 4000 chars (warn at 2000), diagram ≤ 8000 chars, ≤ 6 questions, ≤ 24 glossary terms. sanitizeStudyNotes strips unsafe SVG/URL payloads and NULL bytes.
• X-Ray syntax ([term](#key)) only activates inside studyNotes.text — regular text blocks render it as plain label text.
• Authoring is JSON-only in v12.32. A set_study_notes Vera tool is planned for a future release.

Quality

• Sections via G (3-5 groups). Assertion headlines ("Churn Drops to 2.1%", not "Churn")
• 10+ block types, semantically matched. 4xl cover → 2xl body → 3xl CTA
• Badge every content slide. Closing: recap callout/tag-group + gradient. 960×540 canvas.

Workflow (STRICT — exactly 2 tool calls)

You MUST complete the deck in exactly 2 tool calls. No exceptions. No Read. No validate. No commentary between calls.

Call 1 — Write the complete deck JSON to file:

Use the Write tool to write the entire compact deck JSON to the output file.

Call 2 — Ship or serve:

vela deck ship <file> --output <name.jsx>

Or for local preview: vela server start <file> --port 3030

Done. Do not speak before, between, or after tool calls. NEVER read or print .vela.env.
