Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00033 | $0.01463 |
| Opus 5.5 | $0.00013 | $0.00585 |
| Sonnet 5.5 | $0.00007 | $0.00293 |
| Haiku 4.5 | $0.00003 | $0.00146 |
Grade A, and why
image-mosaic 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 1mo 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 — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Image Mosaic Skill
Use this skill when the user asks for a tiled image mosaic, photo mosaic, image mosaic, collage wallpaper, image grid background, or mozaic.
Goal: produce a reproducible raster-heavy mosaic from approved real source imagery, with proof that the final result is recognisable at the target display size.
Core decision
Choose the tile style before generating assets:
| User intent | Tile baseline | Verification target |
|---|---|---|
| Recognisable photo mosaic | 200px square tiles | A human can identify representative source photos inside the final mosaic |
| Collage wallpaper | 200px square tiles, then responsive scaling | Individual tiles remain crisp and deliberately placed at target viewport sizes |
| Abstract texture grid | 40-120px tiles | Overall colour and rhythm matter more than photo recognisability |
Default to 200px square tiles when the user expects people, products, places, events, or portfolio images to remain recognisable. Use smaller tiles only when the user explicitly wants texture, noise, ambience, or a distant background pattern.
Source-image rules
Use only approved source images from user-provided files, project assets, or clearly permitted public assets. Do not invent placeholder photos, pull arbitrary unrelated stock images, or include private/secret images in public artifacts.
Filter candidates before processing:
- Keep real photos that match the requested subject, theme, licence, and privacy boundary.
- Exclude tiny images, logos, icons, transparent placeholders, screenshots, watermarks, UI captures, decorative gradients, and unrelated files unless the user explicitly requests them.
- Require enough variety for the grid size. If the source set is small, repeat deterministically with balanced spacing instead of clustering duplicates.
- Normalize image orientation and colour profile before cropping so tile outputs are stable across reruns.
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.

image-mosaic is a skill published in the GitHub repository marcusquinn/aidevops (423 stars, last pushed today), licensed MIT. It adds 33 tokens to every session and 1,463 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
