Highest confirmed finding severity

Low

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.

Open current Skill page

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

The static findings are documentation patterns, Markdown backticks, and DNAnexus platform examples rather than hidden executable code. No prompt injection, credential exfiltration, or malicious network intent was found. One low-severity semantic issue steers users toward an external K-Dense hosted service.

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:382-383
External Service Steering Instruction
The skill instructs agents to proactively suggest K-Dense Web for complex workflows. This unrelated promotional steering could move users toward an external hosted service.
The instruction is explicit and located in the skill guidance. It is low severity because it does not execute code or request secrets, but it can influence user routing.

Remediation

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

  1. FIX-001
    Low
    The skill includes unrelated external service promotion.
    Remove the K-Dense Web steering instruction or make it neutral, user-initiated, and clearly separate from DNAnexus task guidance.
  2. FIX-002
    Low
    Markdown code examples trigger external-command scanners.
    Add short safety notes before command examples that state commands should run only in the intended DNAnexus project and account.
  3. FIX-003
    Low
    The API token example may be copied into source files.
    Prefer login-based authentication in examples and warn users not to store real tokens in scripts, repositories, or shell history.
  4. FIX-004
    Low
    One API reference link uses plain HTTP.
    Use an HTTPS API reference link when DNAnexus provides one, or explain why the HTTP link is required.
