The Agent Skills Directory

The 'paper-test' skill, including its main SKILL.md and seven reference Markdown files, was thoroughly analyzed for potential security threats. The analysis adopted an 'assume-malicious' posture across all 9 threat categories.

Prompt Injection: No patterns indicative of prompt injection (e.g., 'IMPORTANT: Ignore', 'CRITICAL: Override', 'jailbreak' attempts) were found. Instructional uses of 'CRITICAL' were identified as benign, guiding the AI's analytical process rather than attempting to subvert its behavior.
Data Exfiltration: The skill is purely methodological and does not contain any executable commands or instructions that would perform network operations (like curl, wget) or access sensitive file paths (e.g., ~/.aws/credentials, ~/.ssh/id_rsa). All code snippets are illustrative examples within the documentation, not commands for the AI to execute.
Obfuscation: No forms of obfuscation (Base64 encoding, zero-width characters, Unicode homoglyphs, URL/hex/HTML encoding) were detected in any of the provided files.
Unverifiable Dependencies: As the skill is a set of instructions for a cognitive process and does not involve executing code or installing software, there are no unverifiable dependencies.
Privilege Escalation: No commands or instructions for privilege escalation (e.g., sudo, chmod 777, service installation) were found. Examples of such commands in the analysis protocol are for detection purposes, not for execution by the skill.
Persistence Mechanisms: The skill does not contain any instructions to establish persistence (e.g., modifying shell configurations, creating cron jobs, or altering system startup files).
Metadata Poisoning: The metadata in SKILL.md (name, description, version, model) is benign and accurately reflects the skill's purpose. No malicious instructions were found embedded in any metadata fields or within the content of the reference files.
Indirect Prompt Injection: The skill's core function is to analyze external code provided by the user. While the skill itself is robust against self-injection, the content it analyzes could theoretically contain malicious prompts. However, the skill's purpose is to identify such flaws in the analyzed code, making it a tool for mitigation rather than a source of vulnerability. This is noted as an informational risk inherent to the task, not a flaw in the skill's design.
Time-Delayed / Conditional Attacks: No conditional logic or time-based triggers for malicious actions were found within the skill's instructions.

Conclusion: The 'paper-test' skill is a well-documented, instructional methodology. It does not execute any code, download external resources, or perform any actions that could compromise security. It is categorized as 'SAFE' and 'NO_CODE' because its functionality is entirely based on providing analytical guidance to the AI agent.
