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.

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 | $0.00033 | $0.02421 |
| Opus 5 | $0.00016 | $0.01210 |
| Sonnet 5 | $0.00007 | $0.00484 |
| Haiku 4.5 | $0.00003 | $0.00242 |
Grade A, and why
gemini-batch 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 3d 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 — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gemini CLI
A flexible standalone CLI tool for Google Vertex AI Gemini models. Supports single prompts, file attachments (images, PDFs, text), batch processing with parallel execution, and image generation with Nano Banana 2 (Gemini's image generation family).
Script location: skills/gemini-batch/gemini-batch.ts
Quick Start
# Simple prompt
skills/gemini-batch/gemini-batch.ts "Explain quantum computing"
# Analyze an image
skills/gemini-batch/gemini-batch.ts -f screenshot.png "Describe this UI"
# Multiple files
skills/gemini-batch/gemini-batch.ts -f before.png -f after.png "Compare these"
# Batch process directory of images
skills/gemini-batch/gemini-batch.ts \
--batch ./screenshots/ \
--out ./analysis/ \
-p prompt.txt
# Generate images with Imagen
skills/gemini-batch/gemini-batch.ts \
--image "A serene mountain landscape at sunset" \
--out ./generated-images/
Configuration
Create a .env file in the skill directory or set environment variables:
VERTEXAI_PROJECT=your-project-id
VERTEXAI_LOCATION=us-central1
GOOGLE_APPLICATION_CREDENTIALS=./your-credentials.json
Usage Modes
1. Single Prompt Mode
# Inline prompt
gemini-batch.ts "Your prompt here"
# Prompt from file
gemini-batch.ts -p system-prompt.txt
# Prompt from file with additional context
gemini-batch.ts -p system-prompt.txt "Additional instructions"
# From stdin
echo "Your prompt" | gemini-batch.ts --stdin
2. With File Attachments
# Single image
gemini-batch.ts -f image.png "Analyze this screenshot"
# Multiple files
gemini-batch.ts -f doc.pdf -f data.json -f image.png "Process these"
# Prompt from file + attachments
gemini-batch.ts -p analysis-prompt.txt -f screenshot.png
Supported file types:
- Images:
.png,.jpg,.jpeg,.gif,.webp - Documents:
.pdf - Text:
.txt,.md,.json,.csv,.html,.xml
3. Batch Mode
Process multiple items in parallel:
# Directory of files with shared prompt
gemini-batch.ts --batch ./images/ --out ./results/ -p "Analyze this UI"
# Directory with subdirectories (each has its own prompt.txt)
gemini-batch.ts --batch ./tasks/ --out ./results/
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.
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.
- 3d ago First seen · 308 lines · 33 tokens per session scan A 96e4c9da1266
gemini-batch is a skill published in the GitHub repository iofold/ainative-claude-plugins (3 stars, last pushed 15d ago), licensed MIT. It adds 33 tokens to every session and 2,421 once invoked, about $0.0002 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 2026-08-31.
