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 Ruby backtick execution and weak cryptography are false positives caused by Markdown code spans, examples, arrows, and prose in SKILL.md. The confirmed risks are intentional RunComfy CLI execution, outbound HTTPS API calls, bearer token handling, and downloaded output files, so users should publish with a clear external-service warning.

Medium
SKILL.md:65-89SKILL.md:178-179
External CLI Invocation Sends User Prompts to RunComfy
The skill instructs agents to run the local RunComfy CLI for HappyHorse text-to-video generation. This is expected behavior, but it executes an external command and submits user prompt content to a third-party API.
The invocation examples and workflow description explicitly show runcomfy commands and POST submission to the RunComfy model API. The behavior is intentional, not hidden, but it has privacy and execution risk.
Medium
SKILL.md:44-46SKILL.md:179SKILL.md:191
Bearer Token and Local Token File Handling
The skill documents RunComfy login, RUNCOMFY_TOKEN use, and token storage under a hidden user configuration path. This is legitimate for authenticated API access, but marketplace users should understand that credentials are required and stored or provided through the environment.
The file explicitly references a bearer token, RUNCOMFY_TOKEN, and ~/.config/runcomfy/token.json. This confirms credential handling, while the documented 0600 mode reduces severity.
Medium
SKILL.md:68SKILL.md:81SKILL.md:89SKILL.md:181SKILL.md:194-195
Generated Output Downloads to Local Filesystem
The skill directs the CLI to download generated outputs into a caller-supplied output directory. The documented host whitelist and file size cap are helpful controls, but the workflow still writes remote model output to local storage.
The command examples require --output-dir and the workflow describes downloading whitelisted URLs. The risk is bounded by documented controls but remains relevant for disk usage and file provenance.
Low
SKILL.md:14SKILL.md:20SKILL.md:174SKILL.md:179-181SKILL.md:194
Hardcoded RunComfy URLs Are Service Documentation
The hardcoded URLs point to RunComfy home, model, documentation, and API endpoints that match the skill purpose. No evidence found of covert callbacks, unrelated domains, or suspicious exfiltration endpoints.
The cited domains are RunComfy documentation and model API domains aligned with the declared function. The skill also states a narrow outbound endpoint policy.

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)
Low
SKILL.md:4-10SKILL.md:24-26SKILL.md:96-109SKILL.md:161-163
Static Backtick and Weak Crypto Alerts Are False Positives
The analyzer flagged many Markdown backticks as Ruby command execution and weak cryptography in prose. Review found documentation, shell examples, arrows, and model descriptions, with no executable Ruby code or cryptographic implementation in the skill file.
The only scanned file is Markdown, and the cited lines are front matter, examples, and prose. No evidence found of Ruby code execution or weak hash usage.

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