Highest confirmed finding severity

Medium

2 confirmed security findings require attention.

Installation context

Check the current Skill page

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

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

Most static findings are false positives caused by Markdown code fences and inline formatting. Six findings contain intended belt or npx commands, while semantic review identified unpinned installations and third-party processing of prompts or images. No prompt injection or malicious exfiltration intent was found.

Capability review items (6)
Medium
Ruby/shell backtick execution
> **Install the belt CLI skill:** `npx skills add belt-sh/cli`
Line 7 presents an npx command that installs a remote community skill. Running it executes package tooling and changes the local skill environment.
Medium
Ruby/shell backtick execution
```bash
The Bash block runs belt login and belt app run commands against external applications. These commands have authentication and network side effects when followed.
Medium
Ruby/shell backtick execution
```bash
The fenced Bash examples invoke belt app run for remote image generation. They are intended external commands, although their arguments are fixed examples.
Medium
Ruby/shell backtick execution
```bash
The Bash block runs three belt app run jobs against an external image model. The commands submit storyboard prompts and create remote processing side effects.
Medium
Ruby/shell backtick execution
```bash
The Bash block invokes the external infsh/stitch-images application through belt. It may send referenced image inputs to third-party processing.
Medium
Ruby/shell backtick execution
```bash
The Bash block contains four npx skills add commands for remote skills. Running them invokes package tooling and modifies the installed skill set.

Risk findings

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

Confirmed security concerns (2)

RISK-001 Medium
Unpinned Remote Skill Installation
The documented npx commands install community skills without immutable versions or commit references, creating dependency and supply-chain exposure.
The commands visibly name remote skill sources without version pins or commit hashes. Their future contents can change independently of this audited file.
RISK-002 Medium
Third-Party Storyboard Data Processing
The belt app run examples submit storyboard prompts and image references to external inference applications, which may expose confidential production material.
The skill identifies inference.sh as the image-generation service and uses belt app run with prompt and image fields. External processing is central to these examples.

Remediation

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

  1. FIX-001
    Medium
    Remote CLI and skill installation commands are not pinned to immutable versions.
    Pin trusted package versions or commit references and ask users to review each source before installation.
  2. FIX-002
    Medium
    Storyboard prompts and image inputs may be processed by an external inference service.
    Disclose the external service, its data handling terms, and advise users to exclude confidential material.

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.

Verify and export

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