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

AI Security Review

scanned 2h ago · by lpm-firewall-ai

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

Static reason
One or more suspicious static signals were detected.
Trigger
User runs `hyperframes skills`, or runs a normal non-JSON CLI command.
Impact
User-authorized agent-skill configuration changes; telemetry reveals sanitized runtime metadata; automatic updates alter the installed HyperFrames package.
Mechanism
Explicit global skill installation plus telemetry and detached package self-update.
Rationale
Source inspection found no install hook or concrete malicious chain. The confirmed risk is explicit-user agent extension mutation and default telemetry/self-update behavior, so this is suspicious rather than malicious.

Decision evidence

public snapshot
AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
  • `dist/cli.js` registers an explicit `skills` command that installs and mirrors skills into global AI-agent skill directories, including `.codex/skills` and `.claude/skills`.
  • `dist/cli.js` enables PostHog telemetry by default and sends runtime, hardware, CI, and sanitized agent-environment metadata to `https://us.i.posthog.com/batch/`.
  • Normal non-JSON CLI use checks npm and can spawn a detached global package update unless disabled.
Evidence against
  • `package.json` has no `preinstall`, `install`, or `postinstall` lifecycle hook.
  • Agent-directory writes are reached through the user-invoked `hyperframes skills` workflow, not package installation.
  • Studio network calls use same-origin `/api/...` endpoints for its local preview/render application.
  • No source evidence of credential harvesting, arbitrary remote payload execution, destructive deletion outside command functions, or covert AI-agent control mutation.
