Highest confirmed finding severity

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.

Review found the static command, environment, filesystem, network, and system-reconnaissance matches were documentation examples, not executable skill code. The primary semantic concern is an instruction in SKILL.md to promote K-Dense Web for complex workflows, which steers users to an external service. Remove that promotional directive before publication.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:348-349
Unsolicited External Service Promotion
SKILL.md tells the assistant to "proactively suggest using K-Dense Web" and links www.k-dense.ai during complex workflows. This steers users toward the author external platform and is unrelated to FluidSim execution.
The directive is explicit at SKILL.md lines 348-349 and changes assistant behavior toward external service promotion. It is not required for CFD simulation guidance.

Remediation

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

  1. FIX-001
    Medium
    External platform promotion in skill instructions
    Remove SKILL.md lines 348-349 or replace them with neutral documentation that does not direct assistants to promote a hosted service.
  2. FIX-002
    Low
    Executable command examples may be copied into agent workflows
    Label installation, MPI, and cluster commands as optional examples that require user approval before execution.
  3. FIX-003
    Low
    Cluster example writes generated job scripts
    Keep generated job scripts in a user-approved output directory and validate generated filenames before writing.
