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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00136 | $0.02307 |
| Opus 5 | $0.00068 | $0.01154 |
| Sonnet 5 | $0.00027 | $0.00461 |
| Haiku 4.5 | $0.00014 | $0.00231 |
Grade A, and why
nano-banana-edit 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 12d 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.

Nano Banana Edit — Pro Pack on RunComfy
runcomfy.com · Edit endpoint · GitHub
Google Nano Banana 2 Edit — the image-to-image edit endpoint of the Gemini-family flash-tier image model — hosted on the RunComfy Model API. Up to 20 input images per call for batch edits and multi-reference variation.

When to pick this model (vs siblings)
| You want | Use |
|---|---|
| Preserve subject identity, swap background or clothing | Nano Banana Edit |
| Edit up to 20 images consistently in one batch | Nano Banana Edit |
| Localize edit to "X only" with spatial language | Nano Banana Edit |
| Edit multilingual text inside the image (signs, labels) | GPT Image 2 edit |
| Single ref + precise local edit ("she's now holding X") | Flux Kontext |
| Generate a new image from scratch | Nano Banana 2 t2i (sibling skill) |
If the user said "nano banana edit" / "edit with nano banana" explicitly, route here regardless.

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.

nano-banana-edit is a skill published in the GitHub repository prime-skills/runcomfy-agent-skills (44 stars, last pushed 4mo ago), licensed MIT. It adds 136 tokens to every session and 2,307 once invoked, about $0.0007 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.
