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

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 2mo 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.

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.
