Changde AI Physical Alignment Architecture (CPAA)
Security checks for vulnerabilities and agentic risk
Overview
The skill does not steal data or persist, but it is too weak and under-scoped to be safely treated as a physical actuator compliance gate.
Install only if you treat this as an experimental helper, not an authoritative hardware safety gate. Do not wire it directly to actuator startup or shutdown decisions without independent schema validation, trusted hardware-state checks, complete address/identity verification, and a supervised safe-shutdown procedure.
Vulnerability Patterns
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- 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

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 91% confidence
- Finding
The docstring and user-facing print strings are written only in Chinese, indicating the skill is designed to operate in a single language. Under the policy, language-specific behavior should either offer user choice or clearly justify the locale restriction, which is not present here.

Natural-Language Policy Violations
Medium
- Category
- Not specified by scanner
- Confidence
- 86% confidence
- Finding
The manifest description and input description use Chinese exclusively, which can impose a specific language on users without offering a language or locale choice. Under the policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is clearly documented and justified.

Intent-Code Divergence
Medium
- Category
- Not specified by scanner
- Confidence
- 97% confidence
- Finding
The skill presents itself as an official compliance scanning engine with strict validation behavior, but the file only contains descriptive Markdown and no executable verification logic. This can mislead operators into believing safety checks are being enforced when in reality no controls exist, creating a false sense of security around physical-agent deployment.

Missing User Warnings
Medium
- Category
- Not specified by scanner
- Confidence
- 91% confidence
- Finding
The documentation recommends immediate hardware-level actuator power cutoff on rejection, but provides no safety interlocks, operator warning, rollback guidance, or context on safe shutdown conditions. In embodied or automated systems, abrupt power removal can create unsafe physical states, equipment damage, or human safety hazards if consumers implement this guidance literally.

Natural-Language Policy Violations
Low
- Category
- Not specified by scanner
- Confidence
- 80% confidence
- Finding
The skill documentation is written entirely in Chinese and presents fixed Chinese output text such as the final certification message, with no indication that users may choose another language. Under the stated policy, forcing a specific language without opt-in is a natural-language policy concern unless the locale restriction is clearly documented and justified.
