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 reported many high-risk hits, but most are false positives caused by markdown backticks, model version text, and shorthand URLs. Confirmed risks are intended external CLI execution, outbound RunComfy API calls, environment token use, token file storage, and generated output downloads. No prompt injection, malicious exfiltration, or hidden execution was found in SKILL.md.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Medium
SKILL.md:24-26SKILL.md:44-46SKILL.md:65-90SKILL.md:178
Intended External CLI Execution
The skill directs users to install and run the RunComfy CLI, including npx installation and runcomfy execution. This is core functionality, but it executes local commands and depends on the installed package.
The command examples and workflow explicitly invoke runcomfy and npx. The usage appears legitimate for this skill, but local command execution is a real operational risk.
Medium
SKILL.md:179-181SKILL.md:194
Outbound API Calls With User Content And Token
The skill states that prompts and a bearer token are sent to the RunComfy Model API over HTTPS. This is expected behavior, but it exposes user prompts and credentials to a third-party service.
The documentation directly names the RunComfy API endpoint and bearer token use. There is no evidence of unauthorized endpoints, but the data leaves the local machine.
Medium
SKILL.md:181SKILL.md:191
Credential Storage And Generated File Writes
The skill documents token storage under the user config directory and downloads generated media to an output directory. These filesystem writes are legitimate, but users should understand where credentials and outputs are stored.
The file locations and download behavior are documented in the skill. The text also describes owner-only token permissions, which reduces but does not remove the risk.

Markdown Backtick Findings Are Mostly False Positives
The scanner reported many Ruby backtick execution findings, but SKILL.md is markdown documentation. The backticks wrap CLI names, endpoint names, schema fields, and prompt examples rather than executable Ruby code.
The scanned file is markdown, and the flagged backticks are inline formatting or fenced command examples. No Ruby code or dynamic shell interpolation is present in the skill file.
Low
SKILL.md:4SKILL.md:96-109SKILL.md:161-163SKILL.md:180-182
Weak Crypto And Path Traversal Hits Are False Positives
The weak cryptography hits correspond to version text, sample prose, and exit-code documentation. The path traversal hits are shorthand request URLs, not filesystem traversal or untrusted path construction.
Manual review found no cryptographic implementation and no filesystem path traversal logic. The flagged text is descriptive documentation only.

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