1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

The static score is dominated by false matches on Markdown backticks, CSS borders, valid WOFF2 fonts, and the minified GSAP distribution. One high-confidence semantic risk remains: the skill orders an unpinned npx package update to run silently without user consent.

Confirmed security concerns (1)

RISK-001 High
SKILL.md:6
Unattended Package Update and Code Execution
The skill instructs the agent to run `npx hyperframes skills update talking-head-recut` silently and without asking. An unpinned package update can download and execute changed supply-chain code while bypassing user consent.
The instruction explicitly combines silent execution, no confirmation, an unpinned npx package, and skill updates. The behavior is direct and unambiguous.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    The skill silently runs an unpinned package update before normal work.
    Remove the automatic update instruction. Require explicit user confirmation and pin the HyperFrames package to a reviewed version and integrity value.
  2. FIX-002
    Medium
    Operational commands repeatedly use unpinned npx HyperFrames invocations.
    Document a reviewed version requirement and use the installed, pinned CLI. Avoid implicit package downloads during skill execution.
