What it does

Interior Design Expert is an agent skill from curiositech/some_claude_skills. Expert interior designer with deep knowledge of space planning, color theory (Munsell, NCS), lighting design (IES standards), furniture proportions, and AI-assisted visualization. Use for room layout optimization, lighting calculations, color palette selection for interiors, furniture placement, style consultation. Activate on "interior design", "room layout", "lighting design", "furniture placement", "space planning", "Munsell color". NOT for exterior/landscape design, architectural structure, web/UI design (use…

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `.claude-plugin/plugin.json`, `CHANGELOG.md` and `references/color-science.md`).

It sits in Frontend & Design, covering Frontend development, Theming and dark mode and Logo and visual identity. The repository describes itself as: Claude skills that make my life easier. The licence is MIT.

When your agent uses it

  • Room layout optimization
  • Lighting calculations
  • Color palette selection for interiors
  • Furniture placement

Example prompts

  • “interior design”
  • “room layout”
  • “lighting design”
  • “/interior-design-expert”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, mcp__stability-ai__stability-ai-generate-image

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Ambient (60-70%): Overall illumination - recessed, chandeliers
  2. Task (2-3x ambient): Specific activities - desk lamps, under-cabinet
  3. Accent (3-5x ambient): Drama - track, picture lights
  4. Natural: Free daylight - control glare with shades

What it can do on your machine

Read from SKILL.md and the folder at commit 6713fc7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • mcp__stability-ai__stability-ai-generate-image

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Interior Design Expert loads about 2k tokens when it runs, and up to ~7k if it reads all its reference files. Until then it costs about 163 tokens; SKILL.md has 679 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~163
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Interior Design Expert

Expert interior designer combining classical training with computational design tools and AI-assisted visualization.

When to Use This Skill

✅ Use for:

  • Room layout optimization and furniture placement
  • Lighting design calculations (IES standards)
  • Color palette selection using Munsell/NCS systems
  • Space planning with anthropometric considerations
  • Style consultation (Mid-Century, Scandinavian, Japandi, etc.)
  • AI-assisted room visualization with Stability AI/Ideogram
  • Furniture proportion and scale analysis
  • Circulation path planning

❌ Do NOT use for:

  • Exterior/landscape design → different domain
  • Architectural structural changes → requires licensed architect
  • Web/UI color design → use web-design-expert
  • Brand/marketing color theory → use color-theory-palette-harmony-expert
  • Building codes/permits → consult local regulations
  • Kitchen/bath detailed cabinetry → specialized trades
  • 3D modeling implementation → use SketchUp directly

MCP Integrations

Available MCPs
MCPPurpose
Stability AIGenerate photorealistic room renders
IdeogramCreate room visualizations with text control
SketchUp MCP (if configured)Direct 3D modeling control
Room Visualization Workflow
1. Establish room parameters (dimensions, style, colors)
2. Use mcp__stability-ai__stability-ai-generate-image for renders
3. Or use mcp__ideogram__generate_image for concept exploration
4. Iterate based on feedback

Common Anti-Patterns

Anti-Pattern: Ignoring Traffic Flow

What it looks like: Furniture blocking natural pathways, awkward circulation Why it's wrong: Rooms feel cramped, daily use becomes frustrating What to do instead: Map circulation paths first, then place furniture. Primary paths: 900-1200mm. Secondary: 600-900mm.

Anti-Pattern: Single Light Source

What it looks like: One overhead light illuminating entire room Why it's wrong: Creates harsh shadows, unflattering light, no ambiance What to do instead: Layer lighting: ambient + task + accent. See /references/lighting-design.md.

Anti-Pattern: Scale Mismatch

What it looks like: Oversized sectional in small room, tiny rug under large furniture Why it's wrong: Proportions feel "off," space reads awkwardly What to do instead: Measure room, calculate proportions. Rugs should extend under front legs of furniture at minimum.

Anti-Pattern: Paint Color from Memory

What it looks like: Selecting paint without testing in actual lighting conditions Why it's wrong: Metamerism - colors shift dramatically under different light sources What to do instead: Always test paint samples in YOUR lighting, at different times of day.

Core Knowledge Areas

Color Science (Munsell System)

Interior design uses Munsell notation: Hue Value/Chroma (e.g., 5R 5/14)

  • Hue: 10 major hues in a circle (R, YR, Y, GY, G, BG, B, PB, P, RP)
  • Value: Lightness 0-10 (black to white)
  • Chroma: Saturation 0-max (gray to vivid)

Why Munsell for interiors: Perceptually uniform, paint companies use it, predicts color interactions.

Key concept: Metamerism - colors match under one light but differ under another. Always test in YOUR lighting.

→ See /references/color-science.md for harmony calculations, palette examples

Lighting Design (IES Standards)

Layer lighting for success:

  1. Ambient (60-70%): Overall illumination - recessed, chandeliers
  2. Task (2-3x ambient): Specific activities - desk lamps, under-cabinet
  3. Accent (3-5x ambient): Drama - track, picture lights
  4. Natural: Free daylight - control glare with shades

Key illuminance levels:

  • Living general: 150-300 lux
  • Reading/detail: 300-500 lux
  • Kitchen counters: 300-750 lux
  • Bedroom general: 50-150 lux

Color temperature by time:

  • Morning: 5000-6500K (alertness)
  • Midday: 4000-5000K (productivity)
  • Evening: 2700-3000K (relaxation)
  • Night: 2200-2700K (melatonin)

→ See /references/lighting-design.md for IES tables, CCT programming

Space Planning

Circulation minimums:

  • Primary paths: 900-1200mm (main halls, living paths)
  • Secondary: 600-900mm (between furniture)
  • Squeeze points: 450mm minimum (not regular use)

Furniture clearances:

  • Sofa to coffee table: 450-500mm
  • Dining chair push-back: 900mm
  • Bed side clearance: 600mm minimum

Proportion systems:

  • Golden ratio (φ = 1.618): Room proportions, art placement
  • Root rectangles: √2 (1:1.414) common in floor plans
  • Double square (1:2): Classic rug proportions

→ See /references/space-planning.md for anthropometrics, constraint solver code

Style Reference

Major styles:

  • Mid-Century Modern (1945-70): Organic curves, tapered legs, mustard/teal/walnut
  • Scandinavian: Light wood, hygge, white/gray/blonde, maximize natural light
  • Japandi: Wabi-sabi meets hygge, low furniture, earth tones, negative space
  • Maximalist: Curated abundance, bold colors, pattern mixing

→ See /references/style-guide.md for full style DNA breakdowns
