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

contribute-catalog 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 2mo 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.

Origin

100% identical to contribute-catalog — 0 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.

Contribute to HyperFrames Registry

Guide the user from idea to merged PR for a new registry block or component.

Workflow

1. Clarify → 2. Scaffold → 3. Build → 4. Validate → 5. Preview → 6. Ship

Step 1: Clarify

Ask what they're building. The registry has two item types:

  • Block (registry/blocks/, type hyperframes:block) — a full standalone composition with fixed dimensions and duration. Caption styles, VFX effects, title cards, lower thirds.
  • Component (registry/components/, type hyperframes:component) — a reusable snippet with no fixed dimensions or duration. CSS effects, text treatments, overlays that adapt to any composition size.

Then ask:

  • One-sentence description of the effect
  • Visual reference (URL, screenshot, or description)
  • Who uses this and when?

Step 2: Scaffold

Create the registry structure:

For blocks:

registry/blocks/{block-name}/
  {block-name}.html
  registry-item.json

For components:

registry/components/{component-name}/
  {component-name}.html
  registry-item.json

Naming convention:

Item name ID prefix Example IDs
cap-hormozi hz hz-cg-0, hz-cw-3
cap-typewriter tw tw-cg-0, tw-ch-0-5
vfx-chrome vc vc-canvas

Use a 2-3 letter prefix. ALL element IDs must use this prefix to avoid collisions in sub-compositions.

registry-item.json for blocks:

{
  "$schema": "https://hyperframes.heygen.com/schema/registry-item.json",
  "name": "{block-name}",
  "type": "hyperframes:block",
  "title": "{Human Title}",
  "description": "{one sentence}",
  "dimensions": { "width": 1920, "height": 1080 }, // adjust: 1080x1920 for portrait/social
  "duration": 10, // adjust for your composition
  "tags": ["{category}", "{subcategory}"],
  "files": [
    {
      "path": "{block-name}.html",
      "target": "compositions/{block-name}.html",
      "type": "hyperframes:composition"
    }
  ]
}

Changes

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.
