use-dom
Verdict safe, but 2 findings (2 low), mainly data exfiltration. Most recent scan 2026-02-07.
This skill appears to be SAFE. It is a documentation/tutorial skill that teaches developers how to use Expo DOM components to integrate web code into React Native applications. The skill contains only instructional markdown content with code examples and no executable scripts. There are no signs of malicious behavior, data exfiltration, prompt injection, or other security threats. The missing optional metadata fields and referenced files are minor documentation issues that do not pose security risks. The skill's purpose (teaching Expo DOM component usage) matches its description, and the content is purely educational.
Scanner's overall assessment (LLM analyzer)
Second scanner: NVIDIA SkillSpector
SkillSpector found no issues but could not fully inspect the package, usually because SKILL.md refers to a file that is not present, so it fails closed to CAUTION instead of SAFE. Read it as "not fully checked", not as a finding. How the two scanners compare across the whole corpus: Two scanners, one corpus.
What this skill does
Use Expo DOM components to run web code in a webview on native and as-is on web. Migrate web code to native incrementally.

Findings
LOW Missing Optional Metadata Fields Data Exfiltrationllm
The skill manifest is missing optional fields 'compatibility' and 'allowed-tools'. While these fields are not required per the agent skills specification, their absence makes it harder to assess the skill's intended usage context and tool requirements. This is informational only and does not indicate a security threat.
SKILL.md:1
compatibility: Not specified
allowed-tools: Not specifiedLOW Referenced Files Not Found in Package Data Exfiltrationllm
The skill instructions reference multiple files (the.py, DOMComponent.py, CodeBlock.py, WebChart.py, Native.py, SyntaxHighlighter.py, and image files) that are not included in the skill package. These appear to be example filenames used in code snippets rather than actual dependencies. However, missing referenced files could indicate incomplete packaging or documentation issues.

What we checked
- Static analyzer. Pattern rules over SKILL.md and bundled files: known-bad commands, exfiltration URLs, secrets, obfuscation.
- Llm analyzer. A language model reads the skill and reports intent-level issues the rules cannot express.
- Meta analyzer. A second model pass that validates, deduplicates and re-scores the other analyzers' findings.
What we did not check
- Runtime behaviour. The skill was not executed; findings come from reading its files.
- Anything fetched at install or run time, including remote scripts, package dependencies, and URLs the skill tells the agent to open.
- Content the analyzers cannot read: images, binaries, and some non-English text.
- Known scanner bypass classes. See the methodology and limitations page.
