Installation context

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.

Most static findings are false positives from Markdown backticks, fixture code, quoted validation commands, and local harness scripts. No prompt injection, credential harvesting, or hidden exfiltration intent was found. The main residual risk is the opt-in eval harness, which can install npm dependencies and run local render/media tools.

Confirmed security concerns (1)

RISK-001 Medium
assets/test-corpus/run.sh:130
Eval Harness Installs External Dependencies
The corpus runner invokes npm install inside fixture projects before rendering baselines. This is documented and intended, but it can reach the npm registry and run dependency lifecycle scripts unless constrained.
The cited line directly invokes npm install when fixture node_modules is missing. The risk is supply-chain exposure during opt-in validation, not hidden malicious intent.

Remediation

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

  1. FIX-001
    Medium
    Eval harness performs npm install for fixtures.
    Add lockfiles or use npm ci with --ignore-scripts, and document that validation may access the npm registry.
  2. FIX-002
    Low
    Fixture HTML loads third-party CDN scripts.
    Pin resources with SRI or vendor local copies for offline, reproducible validation.
  3. FIX-003
    Low
    Render and diff helpers invoke ffmpeg, ffprobe, node, and npx.
    Keep these scripts opt-in, validate input paths, and document required local toolchain permissions.
