Vela Slides — Compact Format

Write the deck as compact JSON. The validator auto-expands compact to full format.

Format

{"n":"Deck Title","C":{color palette},"T":{themes},"S":[slides]}

Color Palette C

Define ALL colors used 2+ times. Include warning/semantic colors alongside brand:

"C":{"$A":"#3B82F6","$B":"#E6F1FF","$C":"#8892B0","$D":"#0A0F1C","$E":"#1e293b","$F":"#3B82F620","$G":"#10B981","$H":"#F59E0B","$I":"#EF4444","$J":"#8B5CF6"}

$A=accent, $G=green, $H=amber, $I=red, $J=purple — use these for per-item color differentiation.

Themes T

"T":{"d":{"b":"$D","c":"$B","a":"$A","p":"60px 72px"},"a":{"b":"$E","c":"$B","a":"$A","p":"36px 48px"}}

Slides S

{"t":"d","n":"Slide Title","d":60,"B":[...blocks...]}

Cover/CTA: add "bgGradient":"linear-gradient(135deg, $D 0%, $E 100%)","align":"center","verticalAlign":"center" Spacers: bare integer. Vary spacer heights: 8 between tight elements, 12 standard, 16 before main block, 24 for major section gaps.

Block Reference

heading — vary s by slide role:

• Cover: {"_":"heading","x":"Assertion Title Here","s":"4xl","w":700}
• Body: {"_":"heading","x":"Specific Claim With Data","s":"2xl"}
• CTA: {"_":"heading","x":"Action-Oriented Closing","s":"3xl","w":700}

text: {"_":"text","x":"Supporting detail.","s":"lg","c":"$C"}

badge — vary c by section context:

• {"_":"badge","x":"THE PROBLEM","c":"$I","b":"#EF444420","i":"AlertTriangle"} (problem=red)
• {"_":"badge","x":"SOLUTION","c":"$G","b":"#10B98120","i":"CheckCircle"} (solution=green)
• {"_":"badge","x":"FEATURES","c":"$A","b":"$F","i":"Layers"} (neutral=blue)

icon-row — each item MUST have a different ic (use $A,$G,$H,$J etc): {"_":"icon-row","I":[{"icon":"...","title":"...","x":"...","ic":"$H","ib":"#F59E0B20"}, ...]}

grid + metric — each metric card gets a distinct color + tinted bg. For problems use warning colors ($I=red, $H=amber): {"_":"grid","cols":3,"g":16,"I":[{"blocks":[{"_":"metric","value":"N%","lb":"Label","s":"3xl","c":"$I"}],"style":{"padding":"20px","background":"rgba(239,68,68,0.08)","borderRadius":"12px"}}, ...]}

flow — 3-5 items with icon + label + sublabel: {"_":"flow","I":[{"i":"Icon","lb":"Step","sublabel":"Detail"}, ...],"arrowColor":"$A","direction":"horizontal"}

callout — use green border for positive insights, amber for warnings: {"_":"callout","x":"Key stat or insight here.","i":"TrendingUp","b":"rgba(16,185,129,0.1)","border":"$G"}

table — include concrete data, not just labels. Use striped + styled header: {"_":"table","H":["Capability","Col2","Col3"],"R":[["row","data","here"]],"striped":true,"headerBg":"$E","headerColor":"$B","cellColor":"$C"}

tag-group — use distinct c per tag, include icons: {"_":"tag-group","I":[{"x":"Action 1","c":"$G","i":"Play"},{"x":"Action 2","c":"$A","i":"Calendar"}],"v":"outline"}

icon: {"_":"icon","name":"Rocket","s":"xl","c":"$A","b":"$F","circle":true} steps: {"_":"steps","I":[{"title":"Step 1","x":"Description"}],"lineColor":"$A","numberColor":"$A"} timeline: {"_":"timeline","I":[{"date":"Q1","title":"Milestone","x":"Detail"}],"lineColor":"$A"} code: {"_":"code","x":"code here","lb":"Language","b":"$E"} quote: {"_":"quote","x":"Quote text.","author":"Name, Title","s":"xl","c":"$B"} progress: {"_":"progress","I":[{"lb":"Metric","value":85,"c":"$A"}],"showValue":true}

Design Rules

• Canvas 960×540. Max 5-7 blocks per slide (spacers don't count).
• Heading sizes MUST vary: 4xl cover, 2xl body slides, 3xl CTA. Never uniform.
• Spacer heights MUST vary: 8, 12, 16, 24. Never all the same value.
• Headlines: specific assertions with data ("AI Resolves 73% of Tickets Automatically"), never labels.
• Semantic colors: red/amber for problems, green for solutions, blue for neutral, purple for features.
• Background: alternate "t":"d" and "t":"a". Cover + CTA use bgGradient.
• Every content slide starts with badge (vary badge color by context).
• Duration: cover/CTA 20-30s, content 60-90s.
• Icons: PascalCase Lucide.

Workflow

1. Write compact JSON to the requested file path
2. Validate: python3 /path/to/vela.py deck validate <file>
3. Brief quality report (5-8 lines): slide count, block types, warnings, 1-2 improvement tips.
