Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00068 | $0.00373 |
| Opus 5 | $0.00034 | $0.00187 |
| Sonnet 5 | $0.00014 | $0.00075 |
| Haiku 4.5 | $0.00007 | $0.00037 |
Grade A, and why
illustration 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.
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.
What it actually says
Illustration
Generate explanatory illustrations starring Popa as intricate hand-drawn sketchnotes. This bare skill is an alias for illustration:popa — hand it straight there.
illustration:popa— Popa, a cute pink blob with a green sprout and a notepad. Intricate hand-drawn sketchnotes: a banner, many linked boxes/notes/arrows/icons on a soft pastel scene — busy but legible. Best for dev/product/system explainers, how-it-works, architecture, walkthroughs, friendly social.
Engine
Popa follows ${CLAUDE_PLUGIN_ROOT}/references/workflow-engine.md (digest → shot list → per-image generation → QA → deliver) and ${CLAUDE_PLUGIN_ROOT}/references/composition-patterns.md (structure types, format presets, the likeness rule). The popa sub-skill supplies the visual DNA, IP anchors, and reference images.
Adding a mascot
To add another character later, create skills/<mascot>/ with SKILL.md (name illustration:<mascot>), references/ (<mascot>-ip.md, <mascot>-style-dna.md, prompt-template.md, qa-checklist.md), and assets/<mascot>-ref/ + assets/examples/. The plugin exposes it automatically.
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.

illustration is a skill published in the GitHub repository stevengonsalvez/agents-in-a-box (23 stars, last pushed today), licensed MIT. It adds 68 tokens to every session and 373 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.
