Vizoid Interior Rendering Prompt Builder

vizoid-prompt-builder

A Claude skill that assembles AI rendering prompts for Vizoid from uploaded architectural wireframes or line drawings.

What It Does

Vizoid is an AI tool that generates photorealistic interior renders from text prompts. Writing those prompts well requires precise, consistent language about materials, fixtures, and spatial relationships — language that needs to stay coherent across every camera angle of a project.

This skill automates that prompt assembly. When you upload a wireframe or line drawing of a room and identify the view, it:

1. Reads the project library — blocks.txt, fixtures.txt, and materials.txt
2. Parses your image — determines which elements are fully visible, partially visible, or out of frame
3. Assembles a prompt — pulls the right modular blocks, resolves fixture slots to full descriptions, and adds explicit exclusions for what's not in frame
4. Saves the view — writes the assembled prompt to views/ with a calibration status flag
5. Outputs a paste-ready prompt — plus a 3-line manifest of what's included, excluded, and flagged

Library Architecture

The skill is built around three library files that serve as a single source of truth for the project's design language:

blocks.txt — Prompt Blocks

Modular prompt fragments organized by tier:

• T1 (Tier 1 — Home-wide): Always-include blocks for style anchor, walls, ceiling, beams, windows, doors, and flooring. Applied to every view regardless of room.
• T2 (Tier 2 — Room-specific): Kitchen (or other room) blocks for cabinets, countertops, backsplash, open shelving, hood, appliances, island, pendants, and dining. Included only when the element is visible in the image.

Each block has a visual trigger (e.g. "trigger: any cabinet face or drawer visible") and named fixture slots that reference fixtures.txt by ID rather than embedding inline descriptions.

fixtures.txt — Fixture Descriptions

Full prose descriptions for every fixture in the project: pendant styles, faucets, appliances, seating. Each entry has:

• A unique ID used in block slots
• Active/alternate/retired status
• Calibration status from Vizoid render testing
• Exclusion language telling the renderer what not to produce

To swap a fixture in a view, change the slot reference — no block edits needed.

materials.txt — Material Specs

Surface material definitions for countertops, flooring, and other finishes. Same structure as fixtures — default, alternates, calibration status. Countertop swap points are flagged in assembled prompts.

views/ — Saved Assembled Prompts

One file per camera angle. Each view file stores the full assembled prompt, the list of active blocks, spatial orientation (room-direction → camera-relative mapping), island mode, and calibration status (PENDING CALIBRATION → CALIBRATED ✓).

Calibration Loop

After submitting a prompt to Vizoid:

• Good render → update the view file status to CALIBRATED ✓
• Bad render → identify which block caused the issue, revise it in blocks.txt so all future views benefit
• New fixture found → add it to fixtures.txt and drop a reference image in the folder

Skill Trigger

The skill activates when you:

• Upload a wireframe, line drawing, or shaded view of a room and identify the room or view angle
• Mention Vizoid, rendering, or interior prompt building

Adding New Rooms

1. Append a TIER 2 — [ROOM NAME] section to blocks.txt
2. Add relevant fixtures to fixtures.txt under a new category header
3. Add any new materials to materials.txt
4. No changes to SKILL.md needed — it reads the library files dynamically
