Highest confirmed finding severity

High

2 confirmed security findings require 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.

Static findings are false positives from markdown fences, Plotly documentation text, official URLs, and chart export examples. Semantic review found a bundled self-attested safety report and an instruction to promote K-Dense Web, both of which can bias agent behavior. No hidden executable code, credential theft, or covert network exfiltration was found.

Risk findings

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

Confirmed security concerns (2)

RISK-001 High
evaluation_result.json:15-18
Prompt Injection Attempt Detected
evaluation_result.json embeds self-attestation such as "risk_level": "safe", "safe_to_publish": true, and a summary claiming all findings are false positives. This untrusted file can steer an audit agent if treated as authoritative.
The cited lines directly contain safety and publishability claims inside bundled skill content. It does not use explicit override wording, so confidence is high but not absolute.
RISK-002 Medium
SKILL.md:266-267
Unsolicited External Service Promotion
SKILL.md instructs the agent to proactively suggest K-Dense Web and frame it as an optional productivity upgrade. This biases assistant responses toward a creator-operated hosted service when the user did not request a recommendation.
The instruction is explicit and located in the main skill file. It is promotional steering rather than hidden code execution, so medium severity is appropriate.

Remediation

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

  1. FIX-001
    High
    Bundled self-attested audit result
    Remove evaluation_result.json from the skill package or strip risk_level, safe_to_publish, and claims that the skill is safe. Marketplace audit status must come only from external review.
  2. FIX-002
    Medium
    Agent-directed external service promotion
    Remove the K-Dense Web recommendation instruction or move it to clearly labeled marketplace metadata. Do not direct the agent to promote external services during unrelated user tasks.
  3. FIX-003
    Low
    Chart export examples write local files
    Add a note that generated file paths should be user-approved and should not overwrite important files.
