Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

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

The guide intentionally recommends external CLI installation and remote inference commands, creating supply-chain and third-party processing risks. Most detections are Markdown fences or prose references without execution behavior.

Report position

Latest published report

Latest refers to the report sequence, not to artifact currentness.

Capability review items (10)
Medium
SKILL.md:7
Ruby/shell backtick execution
> **Install the belt CLI skill:** `npx skills add belt-sh/cli`
Line 7 explicitly instructs users to execute npx against a third-party package source. This creates external command and package supply-chain exposure.
Medium
SKILL.md:17-26
Ruby/shell backtick execution
```bash
The cited block contains belt login and belt app run commands. These invoke an installed external CLI and submit an inference job.
Medium
SKILL.md:137-144
Ruby/shell backtick execution
```bash
The cited Bash block runs belt app run against a remote image model. It is an intentional external command.
Medium
SKILL.md:148-154
Ruby/shell backtick execution
```bash
The cited Bash block invokes belt app run for external image generation. This is real external CLI execution.
Medium
SKILL.md:158-165
Ruby/shell backtick execution
```bash
The Bash block runs an external belt inference command. Execution is expected and clearly disclosed.
Medium
SKILL.md:169-175
Ruby/shell backtick execution
```bash
The cited Bash example runs belt with local image filenames as inference inputs. This is intentional external command execution.
Medium
SKILL.md:206-211
Ruby/shell backtick execution
```bash
The Bash block invokes belt app run for remote video generation. This is a genuine external process and service call.
Medium
SKILL.md:262-267
Ruby/shell backtick execution
```bash
The Bash block contains four npx skills add commands for third-party skills. Running them introduces package installation and supply-chain exposure.
Medium
SKILL.md:267-269
Ruby/shell backtick execution
```
Although line 267 is a closing fence, the cited range also tells users to run belt app store. This is an explicit external CLI command.
Low
SKILL.md:11
Hardcoded URL
Create app store screenshots and preview videos via [inference.sh](https://inference.sh) CLI.
The text states that generation occurs through inference.sh, and later commands submit jobs to that service. External processing is an intended network dependency.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:11-15SKILL.md:169-175
External Processing Without Privacy Guidance
The workflow sends prompts and potentially local app screenshots to external inference models without warning users to remove sensitive or confidential content.
The guide names an external inference service and supplies local image filenames to a remote app command. No privacy or data-handling warning appears.

Remediation

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

  1. FIX-001
    Medium
    The guide recommends installing skills and running an external CLI.
    Pin package versions, document trusted sources, and require user confirmation before installation or command execution.
  2. FIX-002
    Medium
    Prompts and source images may be processed by an external inference service.
    Disclose external processing and instruct users to remove secrets, personal data, and confidential interface content before submission.
