Pre-stack fixes covering all 6 of Miguel's code-level issues, plus
the launch-video skill removal and SFX licensing note flagged by
Rames.
- snapshot.ts: `--describe` resolution was contradictory (comment
said opt-in, code defaulted to "true"). Now: runs by default,
`--describe "custom Q"` overrides the prompt, `--describe false`
opts out. Help text updated to match.
- package.json: removed `sharp` from root devDependencies. Already
declared in packages/cli; root-level was forcing every workspace
to pull the native binary.
- fontMetadataExtractor.ts: dropped the `as unknown as { ... }` cast
and the hand-rolled interface. Use `Font | FontCollection` from
`@types/fontkit` directly + a real type guard. `fsSelection` is
now typed (italic/oblique booleans, not a raw bitfield), so fontkit
API drift would surface as a compile error instead of silently
returning undefined.
- contactSheet.ts: `escapeXml` now also encodes `'` → `'` so
it's safe for both single- and double-quoted SVG attributes.
- agentPromptGenerator.ts: regex metacharacters in `baseName` are
now escaped before being interpolated into `new RegExp(...)`.
- screenshotCapture.ts: cookie-dismiss `button[id*="accept"]`-style
selectors are now scoped under a `[id*="cookie"]` / consent / gdpr
ancestor. Stops false-positives like "Accept invitation".
- skills/launch-video/: removed. Not part of the website-to-hyperframes
scope.
- skills/website-to-hyperframes/assets/sfx/CREDITS.md: documents
Pixabay provenance + license for the 20 bundled .mp3 files.
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes

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.
