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 flagged many command, URL, filesystem, weak crypto, and reconnaissance patterns. Review found no evidence of malicious intent or prompt injection, but the skill legitimately invokes an external CLI, sends user media prompts to RunComfy, and documents local token storage.

Limitations

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

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (3)
Medium
SKILL.md:29-39SKILL.md:71-78SKILL.md:135-147
External CLI execution through RunComfy
TRUE POSITIVE. The skill instructs agents to run the RunComfy CLI. This is expected for the skill, but it executes an external tool and should stay limited to runcomfy commands.
The command examples and security notes directly document runcomfy execution. The allowed tool boundary narrows the risk, so this is medium rather than high.
Medium
SKILL.md:38-39SKILL.md:71-78SKILL.md:135-145
User video and prompts sent to external service
TRUE POSITIVE. The workflow sends a source video URL and continuation prompt to RunComfy. This is core functionality, but users must understand the privacy boundary.
The file states that the CLI posts to the RunComfy Model API and references RunComfy network endpoints. No evidence shows unauthorized exfiltration.
Low
SKILL.md:140
Documented local token storage
TRUE POSITIVE with mitigation. The skill documents that login stores a token in a hidden config path. It also says the token uses mode 0600 and should not be logged.
The storage path and permissions are explicitly documented. This is sensitive credential handling, but the stated permissions reduce practical risk.

Risk findings

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 (3)
Low
SKILL.md:17SKILL.md:25SKILL.md:55SKILL.md:67SKILL.md:113-116SKILL.md:131SKILL.md:151-155
Hardcoded URLs are documentation and allowlisted endpoints
FALSE POSITIVE for malicious networking. The URLs point to RunComfy pages, skills documentation, example input, and stated allowlisted RunComfy endpoints.
The URLs are readable Markdown links or expected service endpoints. I found no encoded destinations, webhook URLs, or unrelated domains.
Low
SKILL.md:5-9SKILL.md:53-58SKILL.md:82SKILL.md:120-129
Weak cryptography and reconnaissance detections are false positives
FALSE POSITIVE. The referenced lines contain description text, prompting guidance, endpoint selection text, or exit code documentation. No cryptographic algorithm or system reconnaissance command appears there.
Line review shows normal prose and an exit code table, not MD5, SHA1, host enumeration, or environment probing.
Low
SKILL.md:7-8SKILL.md:23SKILL.md:29-40SKILL.md:66-78SKILL.md:135-147
Markdown backticks misclassified as Ruby shell execution
FALSE POSITIVE for Ruby backtick execution. The repeated static hits are Markdown inline code spans and fenced shell examples, not executable Ruby source code.
The only file is Markdown and the backticks format commands or endpoint names. No Ruby file or Ruby execution context exists.

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