HyperFrames CLI — create, preview, and render HTML video compositions

AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No install-time malicious behavior was found. The explicit `skills` command can install and mirror package-owned AI-agent skills; normal CLI commands may also schedule a detached self-update after a registry check.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs `hyperframes skills` for agent-skill setup, or runs a non-help/non-JSON CLI command when an update is available.
Impact
Can modify AI-agent skill directories only after an explicit skills command; automatic updates can modify the global HyperFrames installation.
Mechanism
User-invoked agent-skill installation plus package-aligned background self-update.
Rationale
Source inspection found no malicious install hook or exfiltration chain. The explicit cross-agent skill installation/mirroring is a real agent-extension lifecycle risk and warrants a warning under the stated policy.

Decision evidence

public snapshot
AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
  • `dist/cli.js` exposes an explicit `skills` command that installs and mirrors HyperFrames skills into detected AI-agent skill directories.
  • `dist/cli.js` invokes `npx skills add` and creates symlinks/copies under agent skill roots after that user command.
  • `dist/cli.js` performs automatic npm update checks and can launch a detached package-manager self-update after normal CLI use.
Evidence against
  • `package.json` has no `preinstall`, `install`, `postinstall`, or other lifecycle hook.
  • Agent-directory writes are reachable through the user-invoked `hyperframes skills` command, not package installation.
  • No inspected code harvests unrelated credentials or sends local files to an untrusted endpoint.
  • Network use is package-aligned: npm update metadata, HeyGen cloud/auth APIs, and explicit Figma/cloud commands.
  • The studio bundle's fetches target local `/api/...` project routes or user-selected media URLs.
