Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00081 | $0.01044 |
| Opus 5 | $0.00041 | $0.00522 |
| Sonnet 5 | $0.00016 | $0.00209 |
| Haiku 4.5 | $0.00008 | $0.00104 |
Grade A, and why
hyperframes-embedded-captions 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.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Overview
This skill adds burned-in captions to an existing video via a HyperFrames overlay composition. Use it when your source footage needs accessible, styled subtitles without a separate subtitle track. It renders the captioned MP4 deterministically from the HTML overlay.
HyperFrames — Embedded Captions
Add captions/subtitles to talking-head or launch videos. The caption model (drop/rail/embed) and the overlay law (captions are NOT a reserved band).
When to Use
- User wants captions/subtitles on a talking-head video
- User wants a verbatim caption rail (standard lower-third)
- User wants cinematic embedded text behind the subject (the climax beat)
- User wants to add accessibility to a video
- User wants to burn in captions for social media (no subtitle track)
When NOT to Use
- User wants a full video workflow (use
hyperframes-product-launch-video) - User wants a full explainer (use
hyperframes-faceless-explainer) - User wants captions as a sidecar file (SRT/VTT) — this skill burns them in
The Caption Model — Drop / Rail / Embed
| What | How it's shown | |
|---|---|---|
| drop | filler — um/uh, stutters | not shown |
| rail | the default — ordinary spoken content | clean lower-third subtitle, in front |
| embed | a promoted peak — the headline beat | one big word behind the subject (matte occlusion) |
The rail carries most of the text; embed is the scarce, earned peak — ≤1 per beat, never two adjacent, spaced ≥ a beat apart.
The Overlay Law
A caption line is composited ON TOP of the film as an overlay; it is NOT a reserved zone.
- Center the composition on the TRUE vertical center (y = H/2). Do not shift content up to "make room" for captions.
- Content may extend to the canvas bottom.
- Avoid parking critical small readable text (URL, legal line) in the bottom ~80px center span where the caption line sits.
- No machine keep-out gate — judge legibility visually.
Workflow
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.

hyperframes-embedded-captions is a skill published in the GitHub repository oyi77/1ai-skills (12 stars, last pushed today), licensed MIT. It adds 81 tokens to every session and 1,044 once invoked, about $0.0004 per session on Opus 5. 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 2026-09-10.
