🛡️ Prompt Inject Removal

This skill provides a secure way to summarize untrusted external content (web pages, articles, blogs) by routing it through a "Zero-Trust" sanitization prompt.

🚀 Setup & Configuration

This skill is powered by a local, hardened system prompt. No external API keys or complex configuration are required.

📐 Workflow (Sanitization)

  1. Fetch: Raw content is retrieved via `web_fetch` or `browser`.
  2. Delimit: The content is wrapped in `` tags.
  3. Sanitize: The Main Agent processes the content using the rules in [PROMPT.md].
  4. Ingest: Only the resulting sanitized summary is used in the conversation.

Disclaimer: This is a defense-in-depth tool. While it significantly mitigates prompt injection risks, no prompt-based sanitization is 100% foolproof. Review sanitized data before performing state-changing actions.
