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 | $0.00712 |
| Opus 5 | $0.00000 | $0.00356 |
| Sonnet 5 | $0.00000 | $0.00142 |
| Haiku 4.5 | $0.00000 | $0.00071 |
Grade A, and why
extract-frames 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 yesterday.
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.
This is a copy
100% identical to extract-frames — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Extract Frames Command
Extract and describe key frames from video files using Gemini's multimodal video capabilities.
Target: {{args}}
Supported Formats
MP4, MOV, AVI, MKV, WEBM
Workflow
1. Detect Video File
Verify the target video file exists and identify its format:
!{file {{args}} 2>/dev/null || echo "File not found"}
2. Identify Key Frames
Analyze the video to identify significant frames based on:
- Scene changes: Major visual transitions between scenes
- Significant moments: Key actions, reactions, or events
- Composition shifts: Notable changes in framing or camera angle
- Text appearances: Title cards, lower thirds, captions
- Subject changes: New people or objects entering frame
3. Describe Each Frame
For each key frame, provide:
- Precise timestamp
- Detailed visual description
- Subjects and objects present
- Composition and framing notes
- Relevance to the overall narrative
4. Generate Report
Markdown Storyboard:

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.
