Highest confirmed finding severity

Medium

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 31 static findings are false positives caused by Markdown formatting, database method names, schema identifiers, and documentation links. Two implementation examples contain real security-relevant weaknesses: disabled transport security and a DynamoDB write path that does not enforce its claimed concurrency condition.

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 Medium
SKILL.md:311
Transport Security Disabled in EventStoreDB Example
The example connection URI explicitly disables TLS. Reusing this configuration beyond isolated local development could expose event data and credentials in transit.
The URI explicitly contains tls=false, so transport encryption is disabled. The localhost host reduces immediate exposure but does not make the template safe for deployment.
RISK-002 Medium
SKILL.md:385-403
DynamoDB Example Does Not Enforce Optimistic Concurrency
The append method claims conditional concurrency but uses batch put operations without conditions. Duplicate keys can replace historical events and violate append-only integrity.
The method derives versions locally and calls batch.put_item without a condition or transaction. DynamoDB put operations replace items with matching keys.

Remediation

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

  1. FIX-001
    Medium
    The EventStoreDB example disables TLS in its connection URI.
    Use a TLS-enabled URI by default and label plaintext localhost access as development-only.
  2. FIX-002
    Medium
    The DynamoDB append example uses batch writes without conditional version enforcement.
    Use transactional conditional writes that reject existing stream versions and verify the expected latest version atomically.
