* feat(cli): surface and prune skills removed upstream `skills add` / `init` / `hyperframes skills update` only ever add or refresh — none of them delete a skill that was renamed or dropped upstream (e.g. graphic-overlays → talking-head-recut). `skills check` also ignored any installed skill not in the manifest, so a stale bundle lingered forever with no signal and no cleanup path. - skills check: detect "removed" skills by cross-referencing the vercel-labs/skills lock — a skill the lock attributes to our manifest `source` that the manifest no longer lists. Surface them in the human and --json output and count them toward the non-zero exit so the `check || update` contract gates on them. - skills update: after `skills add --all`, prune those skills via `skills remove -g --yes` so the install fully reconciles with the manifest. Best-effort — a cleanup failure doesn't fail the update. Attribution is via the lock's source field, never the bare directory name: `.../skills` is shared across sources, so skills from other sources (e.g. greensock/gsap-skills) are never touched. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cli): prune removed skills only in the scope they were attributed from Make the cleanup in `skills update` impossible to misfire onto a user's own skills. The prune already only targets names the lock attributes to our source, but it hardcoded `skills remove -g` (global) while `skills add` defaults to project scope — so detection could attribute from one scope's lock while removal hit another, potentially deleting a global skill of the same name from a different source. - checkSkills now returns the located install's `scope`. - skills update removes in that exact scope (`-g` only when global), so attribution scope and removal scope always match. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cli): validate skill names before passing them to skills remove Addresses review feedback: skill names fed to `skills remove` originate as lock-file JSON keys, so a corrupt or crafted lock entry could smuggle a flag-like (`--config=…`) or shell-special token into the spawn — which matters most on the Windows cmd.exe path where arg escaping is fragile. Filter the names through a strict kebab-case pattern and warn on any that are rejected, rather than relying on a `--` separator (the upstream `skills` arg parser silently ignores unknown `-`-prefixed tokens and has no `--` end-of-options handling, so `--` would be a no-op there).

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
