Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

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 analysis reported external command, weak crypto, reconnaissance, and network patterns. Review found the command and blocker hits are false positives from Markdown fences and ordinary billing terms. The only confirmed concern is a hardcoded example billing URL with no request or exfiltration behavior.

Capability review items (1)
Low
SKILL.md:271
Hardcoded example billing URL
The dunning email example contains a fixed https://app.example.com/billing URL. This is a placeholder and no network call is made, but implementers should replace it with a configured customer portal URL.
The URL is present in an email template example and uses the reserved example.com domain. It is low risk because it is not used for data transfer by the skill.

Risk findings

False positive: Markdown code fences flagged as shell execution
The external command findings are Markdown triple backtick fences around documentation examples. No shell command execution, interpreter invocation, or user-controlled command path is present.
Each flagged location is a Markdown code fence delimiter or nearby documentation boundary. The file contains examples, but no Ruby backtick execution syntax.

False positive: Weak crypto terms are billing text
The weak cryptography findings match substrings in normal words such as description or ordinary invoice field names. No cryptographic algorithm use was found at these locations.
The reviewed lines define billing descriptions, invoice line items, and display labels. There is no hash, cipher, key, or encryption operation.

False positive: Identifier fields flagged as reconnaissance
The system reconnaissance findings point to generated billing identifiers and customer or subscription IDs. They do not enumerate host, network, user, or environment information.
The context is subscription and invoice object construction. No commands or APIs collect system metadata.
