Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

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

Open current Skill page

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

Static analysis found many shell and URL patterns, but the Markdown mostly documents expected belt CLI usage and reference links. The confirmed risk is that user-provided TSX code and props are sent to the external inference.sh rendering service, so users need a clear third-party data disclosure warning. No evidence found of prompt injection, credential theft, obfuscation, or weak cryptographic code.

Medium
SKILL.md:17-29SKILL.md:72-129SKILL.md:133-185
User Code Sent to External Rendering Service
The skill instructs users to send TSX component code and props to infsh/remotion-render through the belt CLI. This is expected behavior for remote rendering, but proprietary code, private data, or embedded secrets could be disclosed to inference.sh.
The examples clearly pass code and props to a named remote app through belt. This confirms third-party processing, although the behavior matches the skill purpose.
Medium
SKILL.md:4-7SKILL.md:19-30SKILL.md:190-205
External CLI Commands Required
The skill requires Bash access for belt commands and documents npx installation commands for related skills. The commands are transparent and relevant, but they depend on third-party CLI behavior and local authentication state.
The file explicitly allows Bash(belt *) and shows belt and npx command usage. I found no evidence that arguments are hidden or malicious.
Low
SKILL.md:11-17SKILL.md:209-211
Hardcoded URLs Are Contextual
The hardcoded URLs point to inference.sh, cloud.inference.sh, Remotion documentation, and related platform documentation. They appear to be documentation or service references, not credential exfiltration endpoints.
The URLs are visible Markdown links and align with the skill purpose. Network risk remains because rendering depends on the external inference.sh service.

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (1)

SKILL.md:3SKILL.md:35
Weak Cryptography Matches Are False Positives
Static analysis flagged weak cryptography on metadata and Markdown table lines. No evidence found of MD5, SHA1, encryption routines, or cryptographic decision logic in the skill file.
The cited lines contain description text and a Markdown table header, not crypto code. I did not find evidence of weak cryptographic algorithm usage.
