What is ck:ai-multimodal?

A tool for analyzing images, audio, video, and documents through Google’s Gemini service, and for generating images with Imagen 4 or videos with Veo 3. It requires a Gemini API key and can process files from the command line.

Use it to analyze media, transcribe recordings, extract text from documents or images, read image text with OCR, and create images or videos.

It gives a coding agent access to visual and audio information that text-only tools cannot inspect, including transcription, text extraction, and OCR. It can also rotate among configured API keys after rate-limit errors.

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	$0.00052	$0.01639
Opus 5.5	$0.00021	$0.00656
Sonnet 5.5	$0.00010	$0.00328
Haiku 4.5	$0.00005	$0.00164

Security

Grade A, and why

ck:ai-multimodal 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 1mo ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/check_setup.py, scripts/document_converter.py, scripts/gemini_batch_process.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.

AI Multimodal

Process audio, images, videos, documents, and generate images/videos using Google Gemini's multimodal API.

Setup

export GEMINI_API_KEY="your-key"  # Get from https://aistudio.google.com/apikey
pip install google-genai python-dotenv pillow

API Key Rotation (Optional)

For high-volume usage or when hitting rate limits, configure multiple API keys:

# Primary key (required)
export GEMINI_API_KEY="key1"

# Additional keys for rotation (optional)
export GEMINI_API_KEY_2="key2"
export GEMINI_API_KEY_3="key3"

Or in your .env file:

GEMINI_API_KEY=key1
GEMINI_API_KEY_2=key2
GEMINI_API_KEY_3=key3

Features:

Auto-rotates on rate limit (429/RESOURCE_EXHAUSTED) errors
60-second cooldown per key after rate limit
Logs rotation events with --verbose flag
Backward compatible: single key still works

Quick Start

Verify setup: python scripts/check_setup.py Analyze media: python scripts/gemini_batch_process.py --files <file> --task <analyze|transcribe|extract>

TIP: When you're asked to analyze an image, check if gemini command is available, then use echo "<prompt to analyze image>" | gemini -y -m <gemini.model> command (read model from .codex/.ck.json: gemini.model). If gemini command is not available, use python scripts/gemini_batch_process.py --files <file> --task analyze command. Generate content: python scripts/gemini_batch_process.py --task <generate|generate-video> --prompt "description"

Stdin support: You can pipe files directly via stdin (auto-detects PNG/JPG/PDF/WAV/MP3).

cat image.png | python scripts/gemini_batch_process.py --task analyze --prompt "Describe this"

python scripts/gemini_batch_process.py --files image.png --task analyze (traditional)

Models

Image generation: imagen-4.0-generate-001 (standard), imagen-4.0-ultra-generate-001 (quality), imagen-4.0-fast-generate-001 (speed)
Video generation: veo-3.1-generate-preview (8s clips with audio)
Analysis: gemini-2.5-flash (recommended), gemini-2.5-pro (advanced)

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.
