gemini-batch

gemini-batch is a skill for Claude Code, Codex from iofold/ainative-claude-plugins. It costs 33 tokens per session (2,421 once invoked), scanned A, original, MIT.

A command-line tool for sending prompts and files to Google Gemini models, including groups of files processed together.

In plain words
What is it for?
Use it to analyse text, images, or PDFs; process folders of files; or generate images with Google's image models.
Why use it?
It avoids handling many files one by one and includes retries, result checks, and cached outputs for batch work.

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

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.

The scan reads SKILL.md. This mod also ships 1 executable file (gemini-batch.ts), 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.

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/

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.
