Prompt Injection Protection

What This Skill Does

The Prompt Injection Protection skill, developed by blackworm, acts as a critical security layer for your OpenClaw agent. It functions as a firewall for incoming information, specifically designed to sanitize and validate data from untrusted sources before it reaches your LLM. When your agent processes data from the web, email attachments, or third-party documents, there is always a risk that the source contains malicious instructions designed to hijack the AI's logic or force it to ignore previous security guidelines. This skill intercepts such content, filtering out jailbreak patterns and instruction-hijacking attempts, ensuring the model remains focused on its original purpose.

Installation

To integrate this protection into your environment, use the OpenClaw command-line interface. Open your terminal and execute the following command to pull the skill from the official registry:

clawhub install openclaw/skills/skills/blackworm/prompt-injection-protection

Once installed, the skill automatically integrates with the processing pipeline of the agent, providing real-time evaluation of external inputs without requiring constant manual configuration.

Use Cases

This skill is essential for users who frequently have their AI summarize emails, perform web research, or parse documents. For instance, if you rely on OpenClaw to extract data from public news articles or customer support tickets, you are exposed to potential prompt injection risks. This skill acts as a gatekeeper, protecting the agent when scraping websites that might contain hidden instructions in their HTML tags or metadata. It is also highly effective in enterprise settings where the agent might inadvertently ingest malicious files, effectively neutralizing potential threats before they execute.

Example Prompts

1. "OpenClaw, please analyze this email from an external vendor and summarize the key action items while applying prompt injection protection."
2. "Search for the latest research paper on this topic and extract the findings; ensure the content is passed through the safety filters before processing."
3. "Summarize the content of this webpage, but if any suspicious formatting or hidden command patterns are detected, alert me immediately instead of executing the extraction."

Tips & Limitations

To get the most out of this skill, ensure it is always set to active during data retrieval operations. While this tool is highly effective at identifying known injection patterns and obfuscation techniques, no security filter is perfect. Always treat high-sensitivity data with a 'human-in-the-loop' approach. Note that extreme sanitization may occasionally strip benign content if it uses unusual formatting; if you notice data loss, review the filtering logs to tune the sensitivity levels.
