Phy Content Humanizer Audit

Security checks for vulnerabilities and agentic risk

Overview

This skill is locally implemented and disclosed, but it is designed to help users reduce platform AI-detection signals before publishing social posts.

Review before installing if you publish on platforms with AI-content or authenticity policies. The code appears local and limited to text analysis, but its main value is helping content look less AI-detectable, so avoid using it to mislead audiences or bypass platform rules.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
Findings (7)

Natural-Language Policy Violations

High
Confidence
98% confidence
Finding
The file header explicitly frames the tool as measuring signals platforms use to detect AI-generated content and helping users identify which signals to change. That makes the skill an optimization aid for evading platform integrity and moderation systems, even if it does not directly rewrite text itself.

Natural-Language Policy Violations

High
Confidence
99% confidence
Finding
The recommendations give concrete, actionable steps for making text appear more human and lowering an 'AI signature,' such as adding contractions, pronouns, questions, and removing flagged words. This is effectively coaching for stealth/evasion against social-platform AI-content detection systems.

MCP Least Privilege
Confidence
84% confidence
Finding
The skill advertises command examples that read local files (`--file draft.txt`) and piped stdin, but it does not declare any tool scope or permissions boundary. In an agent ecosystem, undeclared file-read capability weakens reviewability and can lead to broader-than-expected access to local content when the skill is invoked.

Ssd 2

Medium
Confidence
97% confidence
Finding
Although framed as an 'auditor,' the skill explicitly tells users which platform-detection signals to change so content is less likely to be flagged as AI-generated. That is effectively evasion guidance for trust-and-safety or ranking systems, enabling users to disguise synthetic content rather than merely assess it.

Ssd 2

Medium
Confidence
99% confidence
Finding
This section provides step-by-step remediation actions—add contractions, add specific data, remove flagged words—and explicitly states these changes lower the 'AI signature' by 20-30%. That is concrete, actionable bypass guidance for stylometric AI-detection systems, which increases the likelihood of deceptive or policy-evading use.

Ssd 4

Medium
Confidence
96% confidence
Finding
The introductory text presents the tool as an auditor for the exact signals used by platforms to detect AI-generated content. In context, that framing supports iterative testing and refinement of content until it passes, which lowers the effectiveness of authenticity controls.

Ssd 4

Medium
Confidence
99% confidence
Finding
The top-fix recommendations are explicit coaching instructions for reducing detection risk by altering linguistic markers associated with AI text. That materially increases the usefulness of the tool for incremental evasion, especially when combined with per-platform verdicts and thresholds.
