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.

This report does not block or authorize the manifest or ZIP.

The skill is a RunComfy CLI guide for Nano Banana 2 image editing. Confirmed risks are limited to expected external CLI execution, remote API submission, and credential handling. Markdown fences, placeholder URLs, and token-path documentation caused several false positives; no prompt injection or malicious intent was found.

Medium
SKILL.md:10
Ruby/shell backtick execution
Calls `runcomfy run google/nano-banana-2/edit` through the local
The description states that the skill calls runcomfy run google/nano-banana-2/edit through the local CLI. This is expected functionality, but it is real external command execution.
Medium
SKILL.md:23-25
Ruby/shell backtick execution
```bash
The bash block tells the user to run npx skills add from a remote repository. Remote package execution is legitimate here but requires user trust and confirmation.
Medium
SKILL.md:42-43
Ruby/shell backtick execution
1. **RunComfy CLI** — `npm i -g @runcomfy/cli`
The prerequisite instructs npm i -g @runcomfy/cli. Installing a global CLI can execute package code and modify the user environment.
Medium
SKILL.md:43-44
Ruby/shell backtick execution
2. **RunComfy account** — `runcomfy login` opens a browser device-code flow.
The prerequisite instructs runcomfy login, which starts an external auth flow and creates a credential. This is normal for the service but still security-relevant.
Medium
SKILL.md:67-74
Ruby/shell backtick execution
```bash
The bash example invokes runcomfy run google/nano-banana-2/edit with input data and an output directory. This sends data to a remote service and writes output locally.
Medium
SKILL.md:78-87
Ruby/shell backtick execution
```bash
The batch example invokes the RunComfy CLI with user-provided image URLs and an output directory. It is expected behavior but remains external command execution.
Medium
SKILL.md:91-98
Ruby/shell backtick execution
```bash
The targeted edit example invokes runcomfy run with JSON input and a local output directory. This is a real external CLI call.
Medium
SKILL.md:177
Ruby/shell backtick execution
The skill invokes `runcomfy run google/nano-banana-2/edit` with a JSON body matching the schema. The
The How it works section says the CLI submits to the model API, polls, fetches results, and downloads files. This confirms command-driven network and filesystem activity.
Medium
SKILL.md:181
Ruby/shell backtick execution
- **Token storage**: `runcomfy login` writes the API token to `~/.config/runcomfy/token.json` with m
The security section describes runcomfy login storing an API token. This is legitimate credential handling but still security-sensitive external CLI behavior.
Low
SKILL.md:177
Hardcoded URL
The skill invokes `runcomfy run google/nano-banana-2/edit` with a JSON body matching the schema. The
The How it works section names the RunComfy model API and output download domains. This is expected, but prompts and image URLs leave the local environment.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

Remediation

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

  1. FIX-001
    Medium
    External CLI execution and package installation
    Require user confirmation before running npx, npm, or runcomfy commands. Pin trusted CLI versions where possible.
  2. FIX-002
    Medium
    RunComfy token handling
    Do not read or print the token file. Prefer secret managers or RUNCOMFY_TOKEN in CI environments.
  3. FIX-003
    Low
    Remote model API submission
    Tell users that prompts and image URLs are sent to RunComfy. Avoid private images unless the user accepts that transfer.
