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.

Most static alerts are false positives caused by Markdown backticks, documentation links, and explicit token-storage documentation. The skill does intentionally run the RunComfy CLI and send prompts or image URLs to RunComfy, which is disclosed and scoped. No evidence found of prompt injection instructions, covert secret exfiltration, or hidden host reconnaissance.

Capability review items (6)
Medium
SKILL.md:32-43
Ruby/shell backtick execution
```bash
This block documents installing, logging in to, and running the RunComfy CLI. The workflow is intended and constrained, but it is real local command execution with authentication side effects.
Medium
SKILL.md:82-90
Ruby/shell backtick execution
```bash
This example runs runcomfy with user-provided image input and writes generated files to disk. The command is legitimate, but it is real CLI execution and external processing.
Medium
SKILL.md:94-101
Ruby/shell backtick execution
```bash
This example runs runcomfy with user-provided image input and writes generated files to disk. The command is legitimate, but it is real CLI execution and external processing.
Medium
SKILL.md:173
Ruby/shell backtick execution
The skill classifies user intent — simple aspect-ratio swap, reference-style match, or brand-locked
The prose explicitly says the skill invokes runcomfy, posts to the Model API, polls status, and downloads results. That confirms intended external command and network behavior.
Medium
SKILL.md:177
Ruby/shell backtick execution
- **Install via verified package manager only.** Use `npm i -g @runcomfy/cli` or `npx -y @runcomfy/c
The line advises installing the CLI through npm or npx. Using a package manager is legitimate, but global or on-demand package execution is a real supply-chain surface.
Medium
SKILL.md:185-189
Ruby/shell backtick execution
- **Scope of bash usage**: `Bash(runcomfy *)` only.
The line declares Bash usage scoped to runcomfy commands. The scope is narrow, but it still authorizes an external CLI as part of the skill.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:173SKILL.md:183
External Image Processing Disclosure
The skill states that it invokes runcomfy, posts requests to the RunComfy Model API, and downloads results. This is expected behavior, but prompts and image URLs leave the local environment.
Line 173 explicitly describes API posting and downloads, and line 183 lists RunComfy outbound endpoints. The behavior is disclosed and service-limited, so the severity is low.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Shell JSON arguments may be fragile for prompts containing quotes.
    Recommend validated JSON generation, careful shell escaping, or a temporary input file before invoking runcomfy.
  2. FIX-002
    Low
    Third-party processing is required for the core workflow.
    Keep a clear notice that image URLs and prompts are sent to RunComfy before commands run.
  3. FIX-003
    Low
    The CLI persists an authentication token after login.
    Document token revocation or removal and prefer RUNCOMFY_TOKEN for CI or container workflows.
