claude-office: Skill for Claude Code

.claude/skills/office-sprite/SKILL.md

office-sprite is a skill for Claude Code from paulrobello/claude-office. It costs 57 tokens per session (2,023 once invoked), scanned A, original, MIT.

A skill for creating game-ready office object sprites in retro 16-bit pixel art. It generates the image and prepares it for use in the Claude Office Visualizer, including removing the temporary background.

In plain words
What is it for?
Use it to create furniture, equipment, and other isolated office-game assets in a front-facing, slightly top-down perspective.
Why use it?
It provides a repeatable visual style and viewpoint so newly created objects fit the existing office simulation.

This is paulrobello/claude-office's own configuration. It tells Claude Code how to work on claude-office itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-office configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/probello/Repos/claude-office/frontend/public/sprites/[NAME]_raw.png.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

office-sprite scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/process_sprite.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Office Sprite Generator

Create game-ready sprites for the Claude Office Visualizer using Nano Banana MCP and ImageMagick.

Project Context

The Claude Office Visualizer uses a 45-degree front/top-down perspective (NOT isometric). This means:

  • Objects are viewed primarily from the front
  • Slight top-down angle shows a bit of the top surface
  • You do NOT see multiple side faces like in isometric views
  • Similar to classic 2D RPGs or top-down office games

Art Style: Retro 16-bit pixel art with clean edges and limited anti-aliasing.

Workflow

Step 1: Generate with Nano Banana

Use mcpl to call Nano Banana with this prompt template:

mcpl call nanobanana generate_image '{
  "prompt": "[OBJECT DESCRIPTION], front view with slight top-down angle, NOT isometric, pixel art style, retro 16-bit game sprite, isolated on solid magenta background #FF00FF, clean edges, no shadows on background, game sprite asset, centered composition, no text, no watermarks, simple design",
  "output_path": "/Users/probello/Repos/claude-office/frontend/public/sprites/[NAME]_raw.png"
}'

Prompt Variables:

  • [OBJECT DESCRIPTION]: Detailed description of the object (e.g., "Office water cooler dispenser with blue water bottle jug on top of white dispenser stand with hot and cold taps")
  • [NAME]: Sprite filename (e.g., "watercooler", "desk", "plant")

Step 2: VALIDATE THE IMAGE

CRITICAL: Before proceeding with ImageMagick processing, you MUST:

  1. Copy the generated image to the raw location:

    cp "/Users/probello/nanobanana-images/temp_images/[UUID].png" \
       "/Users/probello/Repos/claude-office/frontend/public/sprites/[NAME]_raw.png"
    
  2. View the image using the Read tool to verify:

    • Perspective is correct (front view, NOT isometric/3D cube view)
    • Subject is centered and fully visible
    • Background is solid magenta (may have black letterboxing on sides)
    • Art style matches retro pixel art aesthetic

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
