2 findings: 1 critical severity, 1 high severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.

Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

This skill is an offensive pentesting playbook that explicitly instructs and prioritizes credential theft, data exfiltration (downloading archives), brute-force/initial access, exploitation, and post-exploitation persistence/defense-evasion workflows—actions that enable deliberate malicious behavior or easy misuse.

High

W007: Insecure credential handling detected in skill instructions.

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

The skill instructs the agent to "preserve all field:value pairs" when rephrasing operator notes and to emit exact commands/fields (including auth state, forms, exploit output like shell prompts or credentials), which can force the LLM to reproduce secrets verbatim in its outputs.

Low

Low-risk findings.

1 low severity finding. Worth noting, but not necessarily harmful.

Low

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

SKILL.md specifies that the agent reads the evolving session tree from `<engagement>/ptt.md` (which is written from prior tool outputs like “Web page / Burp response” text and other observed content), and those distillation inputs can include arbitrary outsider-authored web content; thus the runtime LLM context can indirectly ingest free-form text originating from external targets via the file/state and distillation pipeline.
