## What
New skill `hyperframes-registry` that teaches AI coding agents how to install and wire registry blocks and components into HyperFrames compositions.
### Skill structure
```
skills/hyperframes-registry/
SKILL.md — triggers, overview, quick reference
references/
install-locations.md — default paths, hyperframes.json config
wiring-blocks.md — iframe inclusion, data attributes, positioning
wiring-components.md — snippet merging (HTML, CSS, JS, timeline)
discovery.md — manifest reading, item fields, available items table
demo-html-pattern.md — why components ship demo.html, structure conventions
examples/
add-block.md — worked example: data-chart block install + wiring
add-component.md — worked example: shimmer-sweep component install + wiring
```
## Why
Phase B of the catalog plan (PR 10). Without this skill, agents using `hyperframes add` have to guess how to wire installed items into compositions. The skill encodes the iframe/snippet patterns so agents get it right on the first attempt.
## How
- SKILL.md frontmatter triggers on: `hyperframes add`, "block", "component", `hyperframes.json`
- References cover every step: discovery, install, wiring blocks (iframe), wiring components (snippet merge), and the demo.html convention
- Two worked examples walk through complete install-to-preview workflows
- Updated CLAUDE.md skills table + trigger rules, README.md skills table, docs/packages/cli.mdx
## Test plan
- [x] `scripts/lint-skills.ts` passes (checked 4 skill files, no issues)
- [x] `oxfmt --check` passes on all markdown files
- [x] SKILL.md frontmatter has valid `name` and `description`
- [x] All reference links in SKILL.md resolve to existing files
- [x] CLAUDE.md, README.md, and docs CLI page updated with new skill
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4:
npx hyperframes render ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
Manage the bundled Chrome/Chromium installation:
npx hyperframes browser
info
Print version and environment info:
npx hyperframes info
docs
Open the documentation in your browser:
npx hyperframes docs
upgrade
Check for updates and show upgrade instructions:
npx hyperframes upgrade
npx hyperframes upgrade --check --json # machine-readable for agents
