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 | $0.00888 |
| Opus 5 | $0.00000 | $0.00444 |
| Sonnet 5 | $0.00000 | $0.00178 |
| Haiku 4.5 | $0.00000 | $0.00089 |
Grade A, and why
scene-detect 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.

Scene Detect Command
Detect scene changes and transitions in 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. Analyze for Transitions
Scan the video for scene boundaries:
- Monitor for significant visual changes between frames
- Detect changes in color palette, composition, and content
- Identify both hard cuts and gradual transitions
- Track audio changes that coincide with visual transitions
3. Classify Transition Types
Categorize each detected transition:
- Cut: Instantaneous change from one shot to another
- Fade In: Scene gradually appears from black (or white)
- Fade Out: Scene gradually disappears to black (or white)
- Dissolve: One scene gradually blends into the next
- Wipe: One scene replaces another with a moving boundary
- Jump Cut: Cut within the same scene with a noticeable time skip
4. Generate Scene List

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.

scene-detect is a command published in the GitHub repository bybren-llc/safe-agentic-workflow (406 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 888 tokens. 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 2026-09-03.
