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

nano-banana-pro 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate_image.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Nano Banana Pro (Gemini 3 Pro Image)

Use the bundled script to generate or edit images.

Generate

uv run {baseDir}/scripts/generate_image.py --prompt "your image description" --filename "output.png" --resolution 1K

Edit

uv run {baseDir}/scripts/generate_image.py --prompt "edit instructions" --filename "output.png" --input-image "/path/in.png" --resolution 2K

API key

  • GEMINI_API_KEY env var
  • Or set skills."nano-banana-pro".apiKey / skills."nano-banana-pro".env.GEMINI_API_KEY in ~/.clawdbot/clawdbot.json

Notes

  • Resolutions: 1K (default), 2K, 4K.
  • Use timestamps in filenames: yyyy-mm-dd-hh-mm-ss-name.png.
  • The script prints a MEDIA: line for Clawdbot to auto-attach on supported chat providers.
  • Do not read the image back; report the saved path only.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
