Design Context

The foundational skill for all design work. Every other design skill checks this context first. This skill gathers, stores, and serves brand identity, color systems, typography, and design preferences so that all generated visuals are cohesive and on-brand.

Context is saved to .agents/design-context.md for reuse across sessions.

Step 1: Check for Existing Context

Before gathering new information, check for existing design context.

Auto-Detection Sources

Scan the codebase for existing design tokens in this priority order:

1. .agents/design-context.md -- previously saved context (highest priority)
2. tailwind.config.js / tailwind.config.ts -- theme.extend.colors, fontFamily, spacing
3. CSS custom properties -- --color-primary, --font-heading, etc. in :root or globals.css
4. package.json -- project name, description
5. Design token files -- tokens.json, theme.js, design-system.*
6. Existing components -- scan for recurring color values, font stacks, spacing patterns
7. manifest.json / site.webmanifest -- theme_color, name
8. Figma variables -- if Figma MCP is available, pull variables from connected files

Auto-Detection Logic

When scanning Tailwind config, extract:

colors.primary -> Brand primary color
colors.secondary -> Brand secondary color
colors.accent -> Accent color
fontFamily.sans -> Body font
fontFamily.heading or fontFamily.display -> Heading font

When scanning CSS variables, map:

--color-primary, --primary -> Primary color
--color-secondary, --secondary -> Secondary color
--color-accent, --accent -> Accent color
--font-heading, --font-display -> Heading font
--font-body, --font-sans -> Body font
--radius, --border-radius -> Border radius preference

If context is found, present it to the user for confirmation before proceeding.

Step 2: Gather Brand Identity

If no existing context is found, gather the following conversationally. Ask in natural groupings, not as a checklist dump.

Brand Core

Color System

Gather a minimum of 4 color groups. Store as hex codes.

Typography

Type Scale Reference

Use this scale system (base 16px, ratio 1.25):

xs:   12px / 0.75rem
sm:   14px / 0.875rem
base: 16px / 1rem
lg:   18px / 1.125rem
xl:   20px / 1.25rem
2xl:  24px / 1.5rem
3xl:  30px / 1.875rem
4xl:  36px / 2.25rem
5xl:  48px / 3rem
6xl:  60px / 3.75rem
7xl:  72px / 4.5rem

Design Style

Identify the primary style from these archetypes:

Audience and Tone

Brand Marks

Platform Preferences

Step 3: Save Context

Save the gathered context to .agents/design-context.md using this template:

# Design Context

## Brand Identity
- **Name:** [Brand Name]
- **Tagline:** [Tagline]
- **Mission:** [Mission]
- **Industry:** [Industry]

## Color System
| Role | Hex | Usage |

| Primary | #XXXXXX | CTAs, key elements |
| Primary Light | #XXXXXX | Hover, backgrounds |
| Primary Dark | #XXXXXX | Active, dark text |
| Secondary | #XXXXXX | Supporting elements |
| Accent | #XXXXXX | Highlights, badges |
| Neutral 50 | #XXXXXX | Light backgrounds |
| Neutral 100 | #XXXXXX | Card backgrounds |
| Neutral 200 | #XXXXXX | Borders |

- **Icon Style:** [Description]

## Platform Priority
- Web: [priority]
- Mobile: [priority]
- Social: [priority]
- Print: [priority]

Step 4: Using Context in Other Skills

When any other design skill activates, it must:

1. Read .agents/design-context.md first
2. Apply the color system -- never use arbitrary colors
3. Use the specified typography -- load Google Fonts if needed via <link> tag
4. Match the design style archetype
5. Respect the tone and audience preferences

Quick Context Snippet for Other Skills

Other skills should include this check at the top of their workflow:

Before generating any visual:
1. Read .agents/design-context.md
2. Extract: primary color, secondary color, accent, heading font, body font, style archetype
3. If no context file exists, ask the user to run the design-context skill first,
   or use sensible defaults and note that output may not be on-brand

Step 5: Context Updates

When the user wants to update context:

1. Read the existing .agents/design-context.md
2. Ask what they want to change
3. Update only the changed fields
4. Confirm the changes
5. Save the updated file

Never overwrite the entire file for a single field change.

Default Fallbacks

If no context is set and the user wants to proceed anyway, use these defaults:

Primary: #2563EB (blue-600)
Secondary: #7C3AED (violet-600)
Accent: #F59E0B (amber-500)
Neutral: Tailwind gray scale
Heading Font: Inter
Body Font: Inter
Style: Minimal
Tone: Professional

Always note in the output that defaults were used and recommend setting up proper design context.
