Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

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

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

The static external-command and reconnaissance findings are false positives caused by markdown fences, examples, and ordinary testing language. I found one semantic risk: the skill encourages deleting implementation code when TDD was not followed, which can cause unwanted data loss without user confirmation.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:37-43SKILL.md:288
Destructive Development Workflow Instruction
The skill repeatedly tells agents to delete implementation code and start over when TDD was not followed. This can destroy user work if applied without explicit confirmation or version-control safeguards.
The cited lines directly instruct deletion as a workflow response. The behavior is not malicious, but it creates a real risk of unwanted data loss in active workspaces.

Remediation

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

  1. FIX-001
    Medium
    Destructive deletion guidance
    Change deletion instructions to require explicit user confirmation and a clean version-control state before removing or replacing code.
