hyperframes-core

hyperframes-core is a skill for Claude Code, Codex from fanfan-de/anybox. It costs 77 tokens per session (2,066 once invoked), scanned A, original, MIT.

The technical foundation for building a renderable HyperFrames project, where HTML describes the video structure and timing. It covers composition layout, timed clips, nested compositions, variables, media playback, and validation.

In plain words
What is it for?
Use it to structure HyperFrames projects, set timing attributes, organize tracks and clips, create nested scenes, and validate deterministic renders.
Why use it?
It provides the rules needed for a composition to render consistently and play correctly at different times.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

hyperframes-core 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/lib/frame-packets-core.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HyperFrames Core

HyperFrames renders video from HTML. A composition is an HTML file whose DOM declares timing with data-* attributes, whose animation runtime is seekable, and whose media playback is owned by the framework.

This skill is the technical contract — how to build one hyperframes project. The body below is the build guide; per-topic detail lives in references/ (index next), read on demand. Other concerns live in the sibling domain skills — hyperframes-animation, hyperframes-creative, media-use, hyperframes-cli, hyperframes-registry. The capability map in /hyperframes says what each one covers.

References

File Read it to…
references/minimal-composition.md start from the smallest renderable composition skeleton
references/composition-patterns.md choose monolithic vs modular; structure a modular index.html; pick a sub-comp archetype
references/data-attributes.md look up any data-* (root / clip / sub-comp host / legacy aliases); use class="clip"
references/tracks-and-clips.md pick data-track-index, handle same-track overlap / z-index, time a clip relative to another
references/sub-compositions.md wire a sub-composition (host attrs, <template>, per-instance vars) and animate inside it
references/variables-and-media.md declare variables; place <video>/<audio>, set volume, trim
references/determinism-rules.md build a seekable timeline; determinism bans; the animatable-property allowlist; layout / text fit
references/full-screen-motion.md author full-frame motion with shared backgrounds
references/storyboard-format.md author a STORYBOARD.md plan (+ the parsed manifest)
references/review-loop.md run the plan → sketch → build review passes on a live board — shared by every storyboard-planning workflow
references/production-loop.md take an approved plan to a delivered video — the stage dependencies (audio, frames, assembly, transitions, captions, verify, deliver) a freeform build follows directly
references/brief-contract.md the brief's ground rules — mode derivation (collaborative / autonomous), shared field registry, question invariants (the asking itself lives in /hyperframes → the intent layer)
references/brief-format.md author BRIEF.md — the confirmed intent document a workflow's Setup writes and every later step reads
references/script-format.md author the optional SCRIPT.md locked narration
references/subagent-dispatch.md map subagent dispatch verbs (parallel fan-out / background / wait) to your harness
references/frame-worker-core.md the shared frame-worker role contract — each narrative workflow's packet builder prepends it to that workflow's sub-agents/frame-worker.md delta
references/tailwind.md work in a Tailwind v4 project (init --tailwind; runtime contract differs from Studio's v3)

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.
