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 | $0.00174 | $0.02552 |
| Opus 5 | $0.00087 | $0.01276 |
| Sonnet 5 | $0.00035 | $0.00510 |
| Haiku 4.5 | $0.00017 | $0.00255 |
Grade A, and why
nano-banana-2 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 2 — Pro Pack on RunComfy
runcomfy.com · Model page · GitHub
Google Nano Banana 2 — the flash-tier text-to-image model in the Gemini family — hosted on the RunComfy Model API. Optimized for ideation, social-thumbnail batches, and rapid drafts with strong in-image typography.

When to pick this model (vs siblings)
Nano Banana 2 is the flash-tier of the Google image-gen line. Pick it when iteration speed and predictable framing matter more than maximum detail.
| You want | Use |
|---|---|
| Rapid drafts, social thumbnails, batch variants | Nano Banana 2 |
| In-image typography with predictable rendering | Nano Banana 2 |
| Web-grounded image (current events / real entities) | Nano Banana 2 + enable_web_search |
| Image edit (preserve subject, swap background) | Nano Banana Edit (sibling skill) |
| Heavy stylization, painterly look | Flux 2 |
| Maximum prompt adherence + multilingual text | GPT Image 2 |
| 2K–4K hero shots, max realism | Seedream 5 |
| Hyperrealistic portrait | Nano Banana Pro |
If the user said "Nano Banana" / "nano-banana-2" / "Gemini image" explicitly, route here regardless. If they said "Nano Banana" without specifying 2 vs Pro, default to Pro for portraits and 2 for everything else.

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-2 is a skill published in the GitHub repository prime-skills/runcomfy-agent-skills (44 stars, last pushed 4mo ago), licensed MIT. It adds 174 tokens to every session and 2,552 once invoked, about $0.0009 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.
