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 findings for external commands and network access are mostly true positives because the skill instructs users to install and run the inference.sh CLI. The remote shell installer is a confirmed high-risk supply-chain pattern, but I found no evidence of prompt injection or confirmed malicious intent in SKILL.md.

Capability review items (4)
High
SKILL.md:15-17
Remote Shell Installer
TRUE_POSITIVE: The quick start instructs users to pipe a network download directly into sh. This can execute changed or compromised remote installer content before the user can inspect it.
The command pattern is explicit and semantically confirmed by the install instructions. The file later describes checksum verification, but the piped shell path still runs remote code directly.
Medium
SKILL.md:4SKILL.md:20-26SKILL.md:70-78
External CLI Execution
TRUE_POSITIVE: The skill permits Bash execution for infsh and provides several infsh app run examples. This is core functionality, but it increases risk because model-assisted sessions can run external commands.
The external command surface is clearly present and intended. The examples use a named CLI rather than arbitrary shell construction, so the risk is elevated but not automatically malicious.
Medium
SKILL.md:9SKILL.md:20-26SKILL.md:136-167
Third-Party Remote Rendering
TRUE_POSITIVE: The skill sends React and Remotion source code, props, and render settings to inference.sh for processing. Users could expose proprietary video logic or sensitive data in props.
The network processing behavior is documented as the skill's purpose. It is legitimate for this skill, but the privacy and data exposure risk is real.
Medium
SKILL.md:188-203
Additional Package Install Commands
TRUE_POSITIVE: The related skills section tells users to run npx skills add commands for multiple external packages. This expands the supply-chain surface beyond the audited single skill file.
The commands are visible and relevant to package installation. They may be normal documentation, but they ask users to fetch additional unaudited content.

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 (2)
Low
SKILL.md:207-209
Hardcoded Documentation URLs
FALSE_POSITIVE: The hardcoded Remotion and inference.sh URLs are documentation references. I did not find evidence that these links exfiltrate data by themselves.
The URLs appear in a documentation list and do not include encoded local data or secrets. The broader service dependency is covered separately.
Low
SKILL.md:29
SHA-256 Weak Crypto Alert
FALSE_POSITIVE: The weak cryptography alert appears to match a checksum reference. SHA-256 checksum verification is not a weak algorithm indicator in this context.
Line 29 explicitly describes SHA-256 checksum verification for downloads. I did not find MD5, SHA-1, or custom cryptographic code in the reviewed file.

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
