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 | $0.00165 | $0.05975 |
| Opus 5 | $0.00082 | $0.02988 |
| Sonnet 5 | $0.00033 | $0.01195 |
| Haiku 4.5 | $0.00016 | $0.00598 |
Grade A, and why
hyperframes-audio 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 — 471 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HyperFrames Audio
A mix is a set of relationships, not a stack of processors. Two tracks that each sound right alone can be unlistenable together, and the fix is almost never "turn one down" — it is finding what they are fighting over and giving it to whichever one needs it. Every tool here exists to express one of those relationships.
Effects live on the element as data-fx-chain, and preview and render run the
same Web Audio graph — the studio in a live context, the engine in an offline one
inside the browser it already drives. There is one implementation of each effect,
so what you hear while scrubbing is what gets written. You never tune twice.
Clip timing remains /hyperframes-core: audio/video trims and source ranges use
data-start, data-duration, and data-media-start, and crossfades overlap
clips on different tracks. This skill owns placed-track fade-in/fade-out,
crossfade envelopes, track gain/track volume, volume and effect automation,
ducking/voiceover carve, and the effect chain. /media-use owns sourcing,
generation, and preprocessing.
Constant data-playback-rate (0.1..5) is render-safe for picture and
pitch-preserved sound when matching audio/video elements use the same timing,
source offset, and rate. Source speed ramps are not supported because there is
no rate envelope; preprocess a derived synchronized asset. HyperFrames does not
provide automatic waveform sync or drift correction.
For copyable cut/crossfade/retime recipes, use /hyperframes-core → references/creator-editing-recipes.md.
Three attributes carry everything, on the audio/video element itself — or, for
the first two, on an <hf-audio-group> bus (see "One bus for many tracks"):
| Attribute | Holds |
|---|---|
data-fx-chain |
the effects, in signal order |
data-automation |
envelopes on this track's volume or its effect parameters |
data-fx-carve |
the carve's own settings, so it can be re-derived |
The shipped effect families are gain, EQ (highpass, lowpass, peaking, shelves), compressor, limiter, gate, saturate, delay, reverb, chorus, phaser, and bitcrush.
Exact JSON for each, and the rules a lane must satisfy: references/attributes.md.
Every effect with its parameters, ranges and units: references/fx-registry.md.
How to work out what is wrong with a file you cannot hear:
references/diagnosis.md.
Presets, named jobs and one-knob profiles, plus a symptom-to-fix table:
references/presets.md — read that before hand-building a chain, because one
of the presets or named jobs usually already names the problem.
What ships with it
6 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-audio is a skill published in the GitHub repository heygen-com/hyperframes (43,141 stars, last pushed 2d ago), licensed Apache-2.0. It adds 165 tokens to every session and 5,975 once invoked, about $0.0008 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 2026-08-30.
