Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00116 | $0.03108 |
| Opus 5.5 | $0.00046 | $0.01243 |
| Sonnet 5.5 | $0.00023 | $0.00622 |
| Haiku 4.5 | $0.00012 | $0.00311 |
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
89% identical to hyperframes-keyframes — 39 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 — 263 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.
Creator editing boundary
Keyframes own visual motion, not clip assembly. Source-range hard cuts, trim,
splice, and reorder belong to /hyperframes-core: author one media element per
kept range, place it with data-start and data-duration, and select its source
offset with data-media-start. Adjacent ranges make a hard cut. A crossfade
uses overlapping clips on different tracks plus visual opacity keyframes; sound
fades use /hyperframes-audio.
| Creator request | Truthful mechanism |
|---|---|
| Punch-in / punch-out | Keyframe scale with x/y or percentage translation on a non-timed visual/crop wrapper inside the clip. Use a set/short tween for a hard punch and a tween for a smooth move. |
| Smooth multi-state zoom or reframe | Keep one subject wrapper alive and author multiple zoom/reframe states as a pose ladder with per-segment easing. |
| Pan, reframe, or Ken Burns camera move | Animate wrapper translation plus scale. Geometry is authored; this is not face tracking or automatic semantic reframing. |
| Chained camera moves | Chain labeled transform beats on one registered seek-safe timeline. |
| Match cut or whip pan | /hyperframes-animation owns the visual handoff; /hyperframes-registry supplies primitives; keyframes preserve authored geometry, direction, and velocity. There is no automatic matching-frame discovery. |
| Crop and mask reframe | Interpolate clip-path or a mask on an inner visual wrapper to crop/reframe without changing source time. Polygon keyframes can form a polygon/mask transition. |
| Directional wipe cut or iris/reveal cut | Animate a mask/clip boundary across overlapping visual clips; /hyperframes-animation owns the handoff choreography. |
| Split-screen handoff | Keep both visual clips placed by core, then keyframe their inner crop/mask wrappers and divider geometry. |
| Constant source retime | /hyperframes-core owns normalized data-playback-rate (0.1..5) for render-safe picture and pitch-preserved sound. It is constant for the whole media element. |
| Source speed ramps | Not supported: there is no time-varying playback-rate envelope. Preprocess a derived media asset, then place it through core. |
| Freeze / hold | A visual pose, final source frame, or finished sub-composition can hold. Arbitrary mid-source freeze is not supported; preprocess a still/derived segment, place it as its own clip, then resume with another source range. |
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 EthanYoQ/Skill-hub (11 stars, last pushed 9d ago), licensed MIT. It adds 116 tokens to every session and 3,108 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 89% identical to hyperframes-keyframes, differing in 39 lines, and is treated as a copy.
