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.

Open current Skill page

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

Most static findings are false positives from markdown examples, API reference tables, and evaluation prompts. One medium-risk finding is confirmed because the deprecated skill description includes an npx installer command for a replacement skill. No prompt injection or data exfiltration intent was found.

Capability review items (1)
Medium
SKILL.md:6
Ruby/shell backtick execution
`npx skills install mcp-use/mcp-use --skill mcp-app-builder`
The skill frontmatter includes an npx skills install command that can fetch and install another skill from a repository. It may be legitimate migration guidance, but it is still an external package execution path that should require explicit user review.

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
    Replacement skill installation command in the skill description.
    Remove the npx install command from frontmatter, or present it only as a manual migration note that requires explicit user confirmation and source review.
  2. FIX-002
    Low
    Documentation examples trigger many command, network, and environment-access scanners.
    Label examples as non-executable placeholders and avoid shell-like commands in activation text where possible.
