Guard external fetches against prompt injection, downloads, and PII leaks.
Guard external fetches against prompt injection, downloads, and PII leaks.
This Claude skill adds a security baseline around WebFetch, WebSearch, GitHub reads, foreign repository documents, PDFs, and MCP outputs. It quarantines external content as data, scans for injection patterns and hidden Unicode, blocks recursive fetches and risky downloads, protects personal information in URLs, and provides optional pre- and post-fetch hooks.
