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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.03667
Opus 5.5	$0.00000	$0.01467
Sonnet 5.5	$0.00000	$0.00733
Haiku 4.5	$0.00000	$0.00367

Security

Grade A, and why

nanobana-image-generator 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.

The scan reads SKILL.md. This mod also ships 6 executable files (__init__.py, scripts/generator.py, scripts/run.sh, …), 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.

Nano Banana Image Generator

Google Gemini 2.5 Flash Image (Nano Banana) model for generating, editing, and creating AI-powered visual content including infographics, product photos, illustrations, and more.

Purpose

Provide farmers and agricultural content creators with AI-powered image generation capabilities using Google's Nano Banana model. This skill enables creation of professional infographics, product mockups, educational visuals, and marketing assets for agricultural documentation, presentations, and promotional materials.

Problem Solved

Creating high-quality agricultural visual content is expensive and time-consuming. Hiring designers for infographics, product photos, and illustrations costs thousands annually. Farmers need professional visuals for grant applications, market materials, educational content, and social media, but lack design skills and budgets. This skill provides free AI-powered image generation for agricultural contexts.

Capabilities

Generate text-to-image visuals from natural language descriptions
Create multi-panel infographics with data visualizations
Generate product mockups and commercial photography
Edit existing images with text prompts (add, remove, modify elements)
Style transfer and artistic transformation
Character consistency across multiple images (up to 14 reference images)
Support for aspect ratios (1:1, 16:9, 21:9, 9:16, etc.)
Multiple resolution options (1K, 2K, 4K)
Google Search integration for real-time data grounding
Batch image generation for multiple concepts
Multi-turn conversation for iterative refinement
SynthID watermark included on all generated images

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.
