Highest confirmed finding severity

High

2 confirmed security findings require attention.

Installation context

Check the current Skill page

This page summarizes report evidence only. The Skill page provides the canonical install advisory.

Open current Skill page

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

All 18 static detections are false positives caused by Markdown backticks around tool names, paths, parameters, and examples. The installation workflow still presents supply-chain and path traversal risks because it copies retrieved files without content review, integrity verification, or path validation.

Report position

Latest published report

Latest refers to the report sequence, not to artifact currentness.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Risk findings

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

Confirmed security concerns (2)

RISK-001 High
SKILL.md:54-58SKILL.md:62-69
Unreviewed Third-Party Skill Installation
The workflow retrieves all registry files, including instructions and scripts, then writes them into the active Claude skills directory without security review or integrity verification.
The documented workflow explicitly retrieves every packaged file and installs each file. No trust check, content inspection, or integrity verification is required.
RISK-002 High
SKILL.md:65-68
Unvalidated Installation Paths
The workflow interpolates a registry slug and filename into destination paths without requiring validation, allowing malicious path components to write outside the skill directory.
The destination templates use returned identifiers directly and specify no containment check. Exploitation depends on whether the registry permits crafted slugs or filenames.

Remediation

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

  1. FIX-001
    High
    Retrieved third-party files are installed without a security review or integrity check.
    Show the complete file manifest, inspect instructions and scripts, verify the source and hashes, then request confirmation before writing files.
  2. FIX-002
    High
    The installation workflow does not validate the slug or returned filenames.
    Reject absolute paths, parent traversal, and links, then confirm every resolved path remains inside the selected skill directory.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.
