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 | $0.00089 | $0.02307 |
| Opus 5.5 | $0.00036 | $0.00923 |
| Sonnet 5.5 | $0.00018 | $0.00461 |
| Haiku 4.5 | $0.00009 | $0.00231 |
Grade A, and why
hyperframes-keyframes 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.
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
86% identical to hyperframes-keyframes — 82 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.
How it starts
The opening of the file, as written. The whole thing — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HyperFrames Keyframes
Keyframes are a pose contract: visible states, continuous subject identity, seek-safe runtime, verified pixels.
Use hyperframes-animation for broad scene recipes.
Use hyperframes-cli for full command docs.
Use references/keyframe-patterns.md only when choosing implementation mechanisms, not visual style.
Procedure
- Identify the animated subject, visible states, final state, and runtime.
- Choose the smallest mechanism that proves the prompt. Read
references/keyframe-patterns.mdonly if the mechanism is unclear. - Author seek-safe keyframes in the declared runtime. Build synchronously and register the runtime instance.
- Verify with lint, validate,
hyperframes keyframes, one focused--shot, and snapshots at proof times. - If proof fails, fix the source keyframes and rerun the smallest failing diagnostic before rendering.
Contract
- Name the moving subject.
- Name the poses needed to prove the intended motion, including the final state.
- Keyframe visible channels, not hidden helper state.
- Preserve object identity when continuity matters.
- Crossfade only when the intended motion is replacement or dissolve.
- Hold readable or semantic states long enough to see.
- Final frame is part of the animation, not cleanup.
- Do not reset to rest unless requested.
- Do not end on black unless requested.
- If editing a starter scene, preserve layout, copy, assets, colors, and final state unless asked to redesign.
Runtime Rules
GSAP:
- build synchronously at page load
- use
gsap.timeline({ paused: true }) - register as
window.__timelines[compositionId] - registry key must match
data-composition-id - do not call
tl.play()for render-critical motion - keep repeats finite
CSS keyframes:
- finite duration and iteration count
- deterministic delay
animation-fill-mode: both- use
data-startwhen timing belongs to a clip
Anime.js:
- create synchronously
autoplay: false- finite duration and loops
- push every instance to
window.__hfAnime
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-keyframes is a skill published in the GitHub repository maiscafe/video_motion (2 stars, last pushed 3mo ago), licensed MIT. It adds 89 tokens to every session and 2,307 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to hyperframes-keyframes, differing in 82 lines, and is treated as a copy.
