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.

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

All 54 static findings evaluated. The 36 'Ruby/shell backtick execution' findings are false positives: backticks in this skill are markdown code formatting, not Ruby execution. The 13 'system reconnaissance' findings are false positives: commands like 'higgsfield account status' are legitimate CLI operations. The 'pipe to shell' pattern (curl | sh at SKILL.md:29) is the official CLI install method shown in a markdown code block. No cryptographic operations exist in this file - the 'weak crypto' finding is a scanner artifact. No prompt injection, data exfiltration, or malicious intent detected.

Low
SKILL.md:29
Pipe to shell install pattern in markdown code block
SKILL.md:29 contains 'curl -fsSL https://raw.githubusercontent.com/higgsfield-ai/cli/main/install.sh | sh' inside a markdown code block. This is the official CLI install method for the Higgsfield tool. The pattern is inherently dangerous (pipe from web to shell) but appears in an instructional code block pointing to the project's own GitHub. The skill instructs the AI to run this when the CLI is not on PATH. This is a legitimate bootstrap step but should be documented as a minor risk.
The pipe-to-shell pattern is present but the URL points to the official Higgsfield GitHub org install script. This is a standard CLI bootstrap pattern, not an attack.
Low
SKILL.md:29
Hardcoded external URL in bootstrap instructions
SKILL.md:29 references a hardcoded URL to raw.githubusercontent.com. The URL points to the official Higgsfield CLI install script. This is a legitimate dependency for the skill to function, but any future compromise of that URL would affect installations.
The URL is from the project's own GitHub org and is the documented install method. Risk is limited to the trustworthiness of the upstream repository.
