 ### Rules
 
 - When creating or modifying HTML compositions, captions, TTS, audio-reactive, or marker highlights → invoke `/hyperframes` BEFORE writing any code
+- When installing or wiring registry blocks/components (`hyperframes add`, `hyperframes.json`, block iframes, component snippets) → invoke `/hyperframes-registry` BEFORE writing any code
 - When writing GSAP animations (tweens, timelines, ScrollTrigger, plugins) → invoke `/gsap` BEFORE writing any code
 - After creating or editing any `.html` composition → run `npx hyperframes lint` and `npx hyperframes validate` in parallel, fix all errors before opening the studio or considering the task complete. `lint` checks the HTML structure statically; `validate` loads the composition in headless Chrome and catches runtime JS errors, missing assets, and failed network requests. Always validate before `npx hyperframes preview`.

+name: hyperframes-registry
+description: Install and wire registry blocks and components into HyperFrames compositions. Use when running hyperframes add, installing a block or component, wiring an installed item into index.html, or working with hyperframes.json. Covers the add command, install locations, block iframe wiring, component snippet merging, and registry discovery.
+---
+
+# HyperFrames Registry
+
+The registry provides reusable blocks and components installable via `hyperframes add <name>`.
+
+- **Blocks** — standalone sub-compositions (own dimensions, duration, timeline). Included via `<iframe>` in a host composition.
+- **Components** — effect snippets (no own dimensions). Pasted directly into a host composition's HTML.
+
+## When to use this skill
+
+- User mentions `hyperframes add`, "block", "component", or `hyperframes.json`
+- Output from `hyperframes add` appears in the session (file paths, clipboard snippet)
+- You need to wire an installed item into an existing composition
+- You want to discover what's available in the registry
+
+## Quick reference
+
+```bash
+hyperframes add data-chart              # install a block
+hyperframes add grain-overlay           # install a component
+hyperframes add shimmer-sweep --dir .   # target a specific project
+hyperframes add data-chart --json       # machine-readable output
+hyperframes add data-chart --no-clipboard  # skip clipboard (CI/headless)
+```
+
+After install, the CLI prints which files were written and a snippet to paste into your host composition. The snippet is a starting point — you'll need to add `data-start` and `data-track-index` attributes when wiring blocks.
+
+Note: `hyperframes add` only works for blocks and components. For examples, use `hyperframes init <dir> --example <name>` instead.
+
+## Install locations
+
+Blocks install to `compositions/<name>.html` by default.
+Components install to `compositions/components/<name>.html` by default.
+
+These paths are configurable in `hyperframes.json`:
+
+```json
+{
+  "registry": "https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry",
+  "paths": {
+    "blocks": "compositions",
+    "components": "compositions/components",
+    "assets": "assets"
+  }
+}
+```
+
+See [install-locations.md](./references/install-locations.md) for full details.
+
+## Wiring blocks
+
+Blocks are standalone compositions — include them via `data-composition-src` in your host `index.html`:
+
+```html
+<div
+  data-composition-id="data-chart"
+  data-composition-src="compositions/data-chart.html"
+  data-start="2"
+  data-duration="15"
+  data-track-index="1"
+  data-width="1920"
+  data-height="1080"
+></div>
+```
+
+Key attributes:
+
+- `data-composition-src` — path to the block HTML file
+- `data-composition-id` — must match the block's internal ID
+- `data-start` — when the block appears in the host timeline (seconds)
+- `data-duration` — how long the block plays
+- `data-width` / `data-height` — block canvas dimensions
+- `data-track-index` — layer ordering (higher = in front)
+
+See [wiring-blocks.md](./references/wiring-blocks.md) for full details.
+
+## Wiring components
+
+Components are snippets — paste their HTML into your composition's markup, their CSS into your style block, and their JS into your script (if any):
+
+1. Read the installed file (e.g., `compositions/components/grain-overlay.html`)
+2. Copy the HTML elements into your composition's `<div data-composition-id="...">`
+3. Copy the `<style>` block into your composition's styles
+4. Copy any `<script>` content into your composition's script (before your timeline code)
+5. If the component exposes GSAP timeline integration (see the comment block in the snippet), add those calls to your timeline
+
+See [wiring-components.md](./references/wiring-components.md) for full details.
+
+## Discovery
+
+Browse available items:
+
+```bash
+# Read the registry manifest
+curl -s https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry/registry.json
+```
+
+Each item's `registry-item.json` contains: name, type, title, description, tags, dimensions (blocks only), duration (blocks only), and file list.
+
+See [discovery.md](./references/discovery.md) for details on filtering by type and tags.

+# Worked Example: Adding a Block
+
+## Scenario
+
+User has an existing HyperFrames project and wants to add an animated chart alongside their video content.
+
+## Steps
+
+### 1. Install the block
+
+```bash
+hyperframes add data-chart
+```
+
+### 2. Wire into index.html
+
+```html
+<div id="stage" data-composition-id="main" data-width="1920" data-height="1080" data-duration="30">
+  <video
+    id="speaker"
+    src="speaker.mp4"
+    data-start="0"
+    data-duration="30"
+    data-track-index="0"
+    style="position: absolute; width: 60%; height: 100%; left: 0; top: 0; object-fit: cover;"
+  ></video>
+
+  <!-- Data chart appears at 5s in the right 40% of the screen -->
+  <div
+    data-composition-id="data-chart"
+    data-composition-src="compositions/data-chart.html"

+    style="position: absolute; right: 0; top: 0; width: 40%; height: 100%;"
+  ></div>
+</div>
+```
+
+### 3. Lint and preview
+
+```bash
+hyperframes lint
+hyperframes preview
+```
+
+### 4. Customize (optional)
+
+Edit `compositions/data-chart.html` — data arrays are at the top of the script, colors are in the CSS rules scoped under `[data-composition-id="data-chart"]`.

+# Worked Example: Adding a Component
+
+## Scenario
+
+User wants to add a shimmer light sweep effect to their title text.
+
+## Steps
+
+### 1. Install the component
+
+```bash
+hyperframes add shimmer-sweep
+```
+
+### 2. Read the snippet
+
+Open `compositions/components/shimmer-sweep.html` and read the comment header.
+
+### 3. Wire into your composition
+
+**HTML** — wrap target elements:
+
+```html
+<div class="shimmer-sweep-target" style="--shimmer-color: rgba(255, 255, 255, 0.5)">
+  <h1 class="title">AI-Powered Video</h1>
+</div>
+```
+
+**CSS** — paste the `.shimmer-sweep-target` and `.shimmer-mask` rules from the snippet.
+
+**JS** — paste the auto-injection script (before timeline code):
+
+```js
+document.querySelectorAll(".shimmer-sweep-target").forEach((el) => {
+  if (!el.querySelector(".shimmer-mask")) {
+    const mask = document.createElement("div");
+    mask.className = "shimmer-mask";
+    el.appendChild(mask);
+  }
+});
+```
+
+**Timeline** — add the sweep:
+
+```js
+tl.fromTo(
+  ".shimmer-sweep-target",
+  {
+    "--shimmer-pos": "-20%",
+  },
+  {
+    "--shimmer-pos": "120%",
+    duration: 1.2,
+    ease: "power2.inOut",
+    stagger: 0.15,
+  },
+  1.5,
+);
+```
+
+### 4. Lint and preview
+
+```bash
+hyperframes lint
+hyperframes preview
+```
+
+### 5. Customize
+
+- `--shimmer-color`: highlight color per element
+- `--shimmer-width`: light band width (default 20%)
+- `--shimmer-angle`: sweep direction (default 120deg)
+- Timeline `duration`, `ease`, `stagger`: control speed and feel

+# The demo.html Convention
+
+## Why components ship demo.html
+
+Every component in the registry ships a companion `demo.html` file alongside its snippet. The demo serves two purposes:
+
+1. **Preview fixture** — the CI preview pipeline renders the demo to generate thumbnail images and preview videos for the catalog docs page.
+
+2. **Usage example** — the demo shows the component effect applied to representative content, serving as a working reference.
+
+## Demo structure
+
+A demo is a complete, standalone HTML composition:
+
+```html
+<!doctype html>
+<html lang="en">
+  <head>
+    <meta charset="UTF-8" />
+    <meta name="viewport" content="width=1920, height=1080" />
+    <title>Component Name — Demo</title>
+    <script src="https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js"></script>
+    <style>
+      /* reset + canvas size */
+    </style>
+  </head>
+  <body>
+    <div data-composition-id="<name>-demo" data-width="1920" data-height="1080" data-duration="N">
+      <!-- Demo content showing the effect -->
+      <!-- Component snippet inlined here -->
+    </div>
+    <script>
+      // GSAP timeline demonstrating the effect
+      window.__timelines = window.__timelines || {};
+      window.__timelines["<name>-demo"] = tl;
+    </script>
+  </body>
+</html>
+```
+
+Key conventions:
+
+- `data-composition-id` is `<component-name>-demo` to avoid collisions
+- The demo is self-contained — all CSS and JS from the snippet is inlined
+- The GSAP timeline is registered on `window.__timelines`
+- Duration should be long enough to showcase the effect (typically 5-8 seconds)
+
+## Blocks don't need demo.html
+
+Blocks are already standalone compositions that can be rendered directly. Only components need the demo wrapper.
+
+## Demos are not installed
+
+The `demo.html` is NOT installed by `hyperframes add` — it exists only in the registry for preview generation and as a reference.

+# Install Locations
+
+## Default paths
+
+| Item type | Default install path                  | Configured by                       |
+| --------- | ------------------------------------- | ----------------------------------- |
+| Block     | `compositions/<name>.html`            | `hyperframes.json#paths.blocks`     |
+| Component | `compositions/components/<name>.html` | `hyperframes.json#paths.components` |
+
+## How path remapping works
+
+The `target` field in each item's `registry-item.json` specifies a default install path. The `add` command remaps the prefix based on `hyperframes.json#paths`:
+
+- Block targets starting with `compositions/` get remapped to `<paths.blocks>/`
+- Component targets starting with `compositions/components/` get remapped to `<paths.components>/`
+
+## hyperframes.json
+
+Created automatically by `hyperframes init`. If it doesn't exist when you run `add`, the CLI creates it with defaults:
+
+```json
+{
+  "$schema": "https://hyperframes.heygen.com/schema/hyperframes.json",
+  "registry": "https://raw.githubusercontent.com/heygen-com/hyperframes/main/registry",
+  "paths": {
+    "blocks": "compositions",
+    "components": "compositions/components",
+    "assets": "assets"
+  }
+}
+```
+
+## Custom layouts
+
+To install blocks into a `scenes/` directory instead of `compositions/`:
+
+```json
+{
+  "paths": {
+    "blocks": "scenes"
+  }
+}
+```
+
+Then `hyperframes add data-chart` writes to `scenes/data-chart.html` instead of `compositions/data-chart.html`. The snippet output reflects the remapped path.

+# Wiring Blocks
+
+Blocks are standalone compositions with their own `data-composition-id`, dimensions, duration, and GSAP timeline. Include them in a host composition using `data-composition-src` on a `<div>`.
+
+## Basic wiring
+
+After `hyperframes add data-chart`, wire it into your `index.html`:
+
+```html
+<div id="stage" data-composition-id="main" data-width="1920" data-height="1080" data-duration="20">
+  <video id="a-roll" src="video.mp4" data-start="0" data-duration="20" data-track-index="0"></video>
+
+  <!-- Block: appears at 2s, plays for 15s, on layer 1 -->
+  <div
+    data-composition-id="data-chart"
+    data-composition-src="compositions/data-chart.html"
+    data-start="2"
+    data-duration="15"
+    data-track-index="1"
+    data-width="1920"
+    data-height="1080"
+  ></div>
+</div>
+```
+
+## Required attributes
+
+| Attribute              | Description                                                          |
+| ---------------------- | -------------------------------------------------------------------- |
+| `data-composition-src` | Path to the block HTML file (relative to index.html)                 |
+| `data-composition-id`  | Unique ID matching the block's internal composition ID               |
+| `data-start`           | When the block appears in the host timeline (seconds)                |
+| `data-duration`        | How long the block plays (seconds, at most the block's own duration) |
+| `data-track-index`     | Layer ordering — higher numbers render in front                      |
+| `data-width`           | Block canvas width (match the block's dimensions)                    |
+| `data-height`          | Block canvas height (match the block's dimensions)                   |
+
+## Timeline coordination
+
+The block's internal GSAP timeline runs independently from the host timeline. The HyperFrames runtime loads the sub-composition, finds its `window.__timelines` registration, and seeks the block in sync with the host, offset by `data-start`. You do NOT need to reference the block's timeline in your host's GSAP code.
+
+## Positioning blocks
+
+To position a block in a specific area of the screen, add CSS:
+
+```html
+<div
+  data-composition-id="data-chart"
+  data-composition-src="compositions/data-chart.html"
+  data-start="2"
+  data-duration="15"
+  data-track-index="1"
+  data-width="1920"
+  data-height="1080"
+  style="position: absolute; right: 0; top: 0; width: 40%; height: 100%;"
+></div>
+```
+
+## Multiple blocks
+
+Include multiple blocks sequentially or overlapping:
+
+```html
+<div
+  data-composition-id="data-chart"
+  data-composition-src="compositions/data-chart.html"
+  data-start="0"
+  data-duration="15"
+  data-track-index="1"
+  data-width="1920"
+  data-height="1080"
+></div>
+<div
+  data-composition-id="flowchart"
+  data-composition-src="compositions/flowchart.html"
+  data-start="15"
+  data-duration="12"
+  data-track-index="1"
+  data-width="1920"
+  data-height="1080"
+></div>
+<div
+  data-composition-id="logo-outro"
+  data-composition-src="compositions/logo-outro.html"
+  data-start="27"
+  data-duration="6"
+  data-track-index="1"
+  data-width="1920"
+  data-height="1080"
+></div>
+```

+# Wiring Components
+
+Components are effect snippets — HTML, CSS, and optionally JS that you merge directly into an existing composition. Unlike blocks, components have no standalone timeline; they participate in the host composition's timeline.
+
+## General process
+
+1. Run `hyperframes add <component-name>`
+2. Open the installed file (e.g., `compositions/components/grain-overlay.html`)
+3. Read the comment header for usage instructions
+4. Copy the parts into your host composition:
+   - **HTML elements** — inside your `<div data-composition-id="...">`
+   - **CSS styles** — into your composition's `<style>` block
+   - **JS setup** — into your composition's `<script>`, before your timeline code
+   - **Timeline calls** — into your GSAP timeline (if the component exposes them)
+
+## Example: grain-overlay (CSS-only, no timeline integration)
+
+```html
+<!-- Paste the overlay div into your composition -->
+<div
+  id="grain-overlay"
+  style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; pointer-events: none; z-index: 100;"
+>
+  <div class="grain-texture"></div>
+</div>
+```
+
+Then paste the CSS keyframes and `.grain-texture` rule into your styles. No GSAP timeline calls needed — the grain animates via CSS `@keyframes`.
+
+## Example: shimmer-sweep (needs timeline integration)
+
+Wrap target elements, paste CSS and JS, then drive the sweep from your timeline:
+
+```js
+tl.fromTo(
+  ".shimmer-sweep-target",
+  {
+    "--shimmer-pos": "-20%",
+  },
+  {
+    "--shimmer-pos": "120%",
+    duration: 1.2,
+    ease: "power2.inOut",
+    stagger: 0.15,
+  },
+  2.0,
+);
+```
+
+## Example: grid-pixelate-wipe (scene transition)
+
+Paste the overlay HTML and CSS, then drive `.grid-cell` scale in your timeline:
+
+```js
+// Cover screen
+tl.to(
+  ".grid-cell",
+  { scale: 1, duration: 0.6, stagger: { amount: 0.6, from: "center" }, ease: "power2.inOut" },
+  5.0,
+);
+// Swap scenes
+tl.set("#scene-a", { opacity: 0 }, 5.6);
+tl.set("#scene-b", { opacity: 1 }, 5.6);
+// Reveal
+tl.to(
+  ".grid-cell",
+  { scale: 0, duration: 0.6, stagger: { amount: 0.6, from: "edges" }, ease: "power2.inOut" },
+  5.6,
+);
+```
+
+## Key principles
+
+- Components inherit the host composition's dimensions and duration
+- Place component HTML at the appropriate z-index relative to your content
+- Read the comment header in each snippet for customizable values
+- Run `hyperframes lint` after wiring to catch structural issues
