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.

All 35 static findings are false positives. The external_commands detections are markdown code block fences (backticks), not shell execution. The network detection is a placeholder URL in example email templates. The blocker detections for weak crypto and system reconnaissance are standard Python code patterns (string assignments, ID generation) used in legitimate billing logic. No prompt injection attempts detected.

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.

Analysis metadata

Audit model: claude

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (4)
High
resources/implementation-playbook.md:16-515SKILL.md:35-44
False Positive: external_commands Detection
Static scanner detected backticks in markdown as shell execution. These are actually markdown code fences (```python ... ```) containing Python code examples for billing automation.
The backtick characters are part of markdown syntax for code blocks, not Ruby/shell command execution. The file contains educational Python code samples for billing implementation.
High
resources/implementation-playbook.md:256
False Positive: Hardcoded URL Detection
Static scanner flagged a URL in example code as potential data exfiltration. This is a placeholder URL in an email template example.
The URL 'https://app.example.com/billing' is a placeholder in an email template example, not an actual network request to external service.
High
resources/implementation-playbook.md:156-165resources/implementation-playbook.md:400-442
False Positive: Weak Cryptographic Algorithm
Static scanner flagged string operations as weak crypto. These are invoice description fields, not cryptographic code.
The flagged code contains invoice line item descriptions and table HTML - plain text strings, not cryptographic algorithms.
High
resources/implementation-playbook.md:69-70resources/implementation-playbook.md:390-392
False Positive: System Reconnaissance
Static scanner flagged ID generation functions as system reconnaissance. These are standard billing system patterns.
generate_id() and customer_id assignments are standard billing system code patterns, not reconnaissance or system discovery.
