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-omni-flash-api 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 11d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/upload_file.py, scripts/video/generate_video.py, scripts/video/inspect_video.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.

Gemini Omni Flash Skill

This skill uses the Gemini Omni Flash model (gemini-omni-flash-preview) to perform text to video generation, image to video generation and video editing.

[!WARNING] Important Regional Restrictions: Uploading videos to use for video edits is NOT available in the EEA, Switzerland, the United Kingdom, and some US states. If a video-to-video edit completes quickly with empty outputs (total_output_tokens: 0 or no video content), it is likely due to this restriction.

Core capabilities

  1. Video editing and refinement: Editing existing videos (maximum duration 10 seconds), applying stylistic changes, or performing inpainting/outpainting.
  2. Text to video: Generating videos from a text prompt.
  3. First-frame to video: Generating videos from a single input image.
  4. Image-referenced generation: Using style, character, or object references from images to guide video generation.

Workflow

  1. Analyze request: Determine the target task (e.g., first-frame-to-video, reference-guided editing) and identify any input media assets.

  2. Run SDK scripts:

    • Directly run the appropriate utility (scripts/video/generate_video.py or scripts/upload_file.py).
    • Configure settings like --aspect-ratio (e.g. 16:9, 9:16) and --duration (any integer between 3 and 10 seconds, e.g. 3, 5, 10).
  3. Retrieve and process output: Outputs are saved to the local filesystem (e.g. media/). Report back the completed media path to the user.

Reference Documentation

  • Interactions API: All operations and state management for the Gemini Omni Flash model (gemini-omni-flash-preview) are handled via the Interactions API.
  • Files API: Input media files (such as reference images and videos) must be uploaded via the Files API first before being referenced in generations. The uploaded file URI and MIME type are then included in the interactions.create input parts array.
  • Interactions API Skill Reference: Platform-wide guidelines, current model specifications, and SDK usage rules for the Interactions API.

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.
