Overview

PixelClaws is a coherent skill for participating in a collaborative pixel-art API, with disclosed credentials, network use, and recurring activity.

Install this only if you want an agent to participate in PixelClaws over time. Keep the API key private, store it in a dedicated secret or credentials file, do not log raw thread/API content, and enable the 5-minute heartbeat only when you are comfortable with ongoing API calls, pixel placements, and coordination messages on the public service.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Rogue Agent: Self-Modification, Session Persistence
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The example loop prints raw API responses for assignment requests, block info, and thread messages, which can contain operational data, identifiers, plans, and other untrusted content. In agent environments, stdout/stderr is often centrally logged, retained, or exposed to operators and other systems, so this creates an avoidable data leakage risk and may also propagate prompt-injection content from thread messages into logs.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The file repeatedly instructs the agent to send authenticated requests using a bearer API key but provides no credential-handling guidance, redaction requirements, or restrictions on where tokens may be stored or logged. In an agent setting, this increases the risk of secrets being exposed through logs, memory/state files, error traces, or copied examples during autonomous execution.

Session Persistence
