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 | $0.00085 | $0.00830 |
| Opus 5 | $0.00043 | $0.00415 |
| Sonnet 5 | $0.00017 | $0.00166 |
| Haiku 4.5 | $0.00009 | $0.00083 |
Grade A, and why
illustration:popa 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.
How it starts
The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
illustration:popa — intricate sketchnote blob
Generate intricate hand-drawn sketchnotes starring Popa: a pink round blob with a green sprout and a notepad. Popa turns a concept, flow, or system into one busy, packed, readable sketchnote on a soft pastel scene — a banner, many linked boxes/notes/arrows/icons, Popa scribbling in the middle — lots of scribblings in the same note, but every word legible.

Core positioning
The goal is to turn a topic — a process, system, argument, or set of features — into one intricate hand-drawn sketchnote: a banner, many small linked ideas in boxes/clouds/tags, arrows and spot icons, with Popa hosting the action. Busy and packed ("lots of scribblings in the same note"), but with clear hierarchy and legible text — no gibberish, ever. Popa is earnest and deadpan; the cuteness is the setup, the situation is the punchline. Popa hosts the note, never just decorates it.
Workflow (engine + Popa specifics)
Follow the five shared steps. Popa specifics:
- Likeness is mandatory: pass
assets/popa-ref/popa_square.png(andtiny_popa2.pngfor the notepad pose) into the backend with "this is Popa; draw THIS exact character — chubby pear body, green sprout, glossy eyes, rosy cheeks — translated into crude hand-drawn pen line art; do not copy the reference's 3D style or background." - Intricate density: pack the page with many linked boxes, notes, arrows and icons — busy, not sparse. Big topics can also become a multi-frame series (see composition-patterns).
- Text integrity (hard rule): decide the exact short labels first and allow ONLY those words in the image; never let the model invent text. If a finished frame has a garbled label, fix it with a text-only edit, not a regenerate. See
references/prompt-template.md. - The notepad gag: when there's room, one tiny legible line on the notepad. Max one per image.
- Pastel background: cream by default (or mint / lavender / blush); for a series keep one tone across frames so they tile. Popa is the only saturated element.

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:popa is a skill published in the GitHub repository stevengonsalvez/agents-in-a-box (23 stars, last pushed today), licensed MIT. It adds 85 tokens to every session and 830 once invoked, about $0.0004 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.
