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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.06036 |
| Opus 5 | $0.00026 | $0.03018 |
| Sonnet 5 | $0.00010 | $0.01207 |
| Haiku 4.5 | $0.00005 | $0.00604 |
Grade A, and why
character-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 10d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 440 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Character Sprite Generator
Create complete, animated character sprite sheets for Claude Office Visualizer agents using Nano Banana MCP and ImageMagick.
Project Context
Characters are office workers rendered in retro 16-bit pixel art style. Each character requires multiple animation sprite sheets for different actions and directions.
Art Style: Retro 16-bit pixel art (SNES/Genesis era), clean pixels, limited colors.
CRITICAL - NO ANTI-ALIASING: All sprites must have sharp, crisp pixel edges with NO anti-aliasing, NO smoothing, NO blending between pixels. Each pixel should be a solid color with hard edges. Anti-aliased sprites look blurry and muddy in the game.
Character Constraints:
- Max width: 60px (matches current agent radius × 2)
- Max height: 75px (25% taller than width allowed)
- Magenta (#FF00FF) chroma key background
Sprite Sheet Technical Specifications
CRITICAL: Grid Layout Requirements
The game engine parses sprite sheets by dividing the total image into a fixed grid. All cells must be uniform with ZERO padding/spacing between them.
┌──────────────────────────────────────────────────────────────────────────────┐
│ NO gaps, borders, or padding between cells. Cells are calculated as: │
│ cell_width = sheet_width / columns │
│ cell_height = sheet_height / rows │
│ Frame at (col, row) starts at pixel (col × cell_width, row × cell_height) │
└──────────────────────────────────────────────────────────────────────────────┘
DO NOT:
- Add visible grid lines or cell borders
- Add padding or spacing between cells
- Use inconsistent cell sizes
- Leave empty cells (fill with magenta background)
Sheet Dimensions & Frame Specifications
| Sheet Type | Total Size | Grid | Cell Size | Frames |
|---|---|---|---|---|
| Idle | 928 × 1152 px | 8 cols × 8 rows | 116 × 144 px | 64 total |
| Walking | 928 × 1152 px | 8 cols × 8 rows | 116 × 144 px | 64 total |
| Typing | 928 × 144 px | 8 cols × 1 row | 116 × 144 px | 8 frames |
| Handoff | 928 × 1152 px | 4 cols × 1 row | 232 × 411 px* | 4 frames |
| Coffee | 928 × 1152 px | 4 cols × 1 row | 232 × 699 px* | 4 frames |
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.

character-sprite is a skill published in the GitHub repository paulrobello/claude-office (511 stars, last pushed yesterday), licensed MIT. It adds 52 tokens to every session and 6,036 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
