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 and medium patterns, but review shows the file is a Markdown skill guide, not executable bundled code. The confirmed risks are legitimate for the skill purpose: it invokes the RunComfy CLI, sends user prompts to RunComfy network endpoints, writes generated audio, and may use a local auth token. Weak crypto, shell substitution, and system reconnaissance alerts appear to be false positives from documentation text and inline examples.

SKILL.md:4SKILL.md:37-48SKILL.md:84-90SKILL.md:95-102SKILL.md:107-114SKILL.md:170SKILL.md:180
External CLI Invocation Required
The skill is designed to run `runcomfy run elevenlabs/elevenlabs/music-generation` and includes setup commands for npm or npx. This is expected behavior, but it gives the skill an external command execution dependency and should be limited to trusted RunComfy CLI commands.
The allowed-tools metadata and examples clearly show intended Bash use with the RunComfy CLI. The commands are documented and scoped, so the risk is real but not evidence of malicious intent.
Medium
SKILL.md:19SKILL.md:27SKILL.md:74SKILL.md:170SKILL.md:178SKILL.md:184-186
Outbound Network Calls to RunComfy Services
The documented workflow sends music prompts and request data to RunComfy Model API endpoints and downloads generated audio from RunComfy domains. This is necessary for the cloud music-generation service, but users should treat prompts and lyrics as data shared with a third party.
The skill explicitly describes API submission, polling, and audio download behavior. The endpoints are vendor domains, and no unrelated exfiltration destination was found.
Medium
SKILL.md:43SKILL.md:48SKILL.md:76SKILL.md:90SKILL.md:102SKILL.md:114SKILL.md:175SKILL.md:179
Local Token and Output File Handling
The skill documents `runcomfy login`, token storage at `~/.config/runcomfy/token.json`, use of the `RUNCOMFY_TOKEN` environment variable, and output downloads to `--output-dir`. This is legitimate credential and output handling, but it requires careful permission and logging controls.
The file directly states where the CLI stores tokens and where generated files are downloaded. The same section warns not to echo or log tokens, which reduces but does not remove operational risk.
Low
SKILL.md:174
Remote Install Guidance Requires User Review
The security section warns agents not to pipe arbitrary remote install scripts into a shell and says operators should review any curl-pipe install path first. This is a positive safety instruction, but the topic is still relevant because users may follow linked installation documentation.
The line is a defensive warning rather than an unsafe instruction. It still touches a sensitive installation pattern, so it is worth preserving as a marketplace warning.

Static Analyzer False Positives in Markdown Text
Many reported Ruby backtick, weak cryptographic algorithm, command substitution, and reconnaissance detections occur inside Markdown prose, inline code, tables, or examples. No Ruby code, cryptographic implementation, or system reconnaissance behavior was found in the reviewed file.
The reviewed file is a single Markdown skill description. The suspicious tokens are documentation examples such as backticks, `music_length_ms`, `$(...)`, and exit-code tables rather than executable logic.
