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.

Evaluated 89 static findings across 182 lines. All pattern matches (external_commands, network, filesystem) are false positives caused by the scanner misinterpreting markdown syntax and documentation examples. The skill is a legitimate video generation wrapper that calls the RunComfy CLI with hardcoded strings. Explicit security documentation confirms HTTPS transmission, no shell injection surface, proper token storage (0600), and file size limits (2 GiB). No confirmed security risks.

Confirmed security concerns (2)

RISK-001 Low

SKILL.md:10-180

Markdown code block syntax flagged as command execution

The static scanner detected 67 instances of 'Ruby/shell backtick execution' in markdown code blocks. These are legitimate code examples showing CLI usage patterns. The actual command invocations use hardcoded strings, not user input.

All flagged locations are markdown fenced code blocks containing example CLI commands with hardcoded strings. No user input injection vector exists in the actual code.

RISK-002 Low

SKILL.md:14-173

Documentation URLs flagged as hardcoded network targets

The scanner flagged URLs in documentation as potential exfiltration targets. These are legitimate documentation links and example media URLs provided by the user.

URLs refer to runcomfy.com homepage, documentation, and example media placeholders. The skill explicitly documents that outbound endpoints are limited to model-api.runcomfy.net.
