1 confirmed security finding requires attention.

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.

Most static findings are false positives caused by Markdown code fences and inline formatting. Confirmed risks are external package installation, third-party CLI execution, and transmission of prompts or search queries to remote services.

Capability review items (6)
Medium
SKILL.md:7
Ruby/shell backtick execution
> **Install the belt CLI skill:** `npx skills add belt-sh/cli`
Line 7 instructs users to run npx against an external package. Installation can execute third-party package lifecycle code and creates a supply-chain risk.
Medium
SKILL.md:17-31
Ruby/shell backtick execution
```bash
The Bash block runs belt login and remote belt app commands. These commands authenticate and send supplied inputs to external services.
Medium
SKILL.md:103-116
Ruby/shell backtick execution
```bash
The Bash block runs belt app commands against remote image-generation providers. Execution depends on an external CLI and service.
Medium
SKILL.md:169-174
Ruby/shell backtick execution
```bash
The Bash block invokes a remote answer service through belt. The query leaves the local environment and depends on third-party execution.
Medium
SKILL.md:201-213
Ruby/shell backtick execution
```bash
The Bash block invokes remote image-generation and HTML-rendering applications through belt. Both operations execute outside the skill and process supplied content.
Medium
SKILL.md:240-244
Ruby/shell backtick execution
```bash
The Bash block recommends three npx package installation commands. Running unpinned third-party packages creates a supply-chain and code-execution risk.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:21-30SKILL.md:103-115SKILL.md:169-173
User Content Sent to Third-Party Services
Image prompts and research queries are submitted to remote providers through belt. Sensitive product details or personal data could leave the local environment.
The commands explicitly pass prompt and query fields to named remote applications. The skill provides no warning against submitting sensitive information.

Remediation

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

  1. FIX-001
    Medium
    The skill recommends installing external packages with npx.
    Pin package versions and commits, document package provenance, and require user confirmation before installation.
  2. FIX-002
    Medium
    The skill sends prompts and search queries to third-party services through belt.
    Disclose remote data processing and tell users to remove secrets, personal data, and confidential business information.
  3. FIX-003
    Medium
    The allowed Bash pattern permits any belt subcommand.
    Restrict allowed commands to the required belt operations and require confirmation before login or remote execution.
