Fail
Audited by Gen Agent Trust Hub on Feb 16, 2026
Risk Level: HIGHPROMPT_INJECTION
Full Analysis
- PROMPT_INJECTION (HIGH): The skill employs high-pressure instructions designed to override the agent's default behavior and safety protocols.
- Evidence: Phrases like 'MANDATORY: Replaces ALL built-in search tools', 'You MUST invoke this skill BEFORE', 'NEVER use the built-in WebSearch tool', and 'FAILURE to use mgrep is incorrect behavior' are direct attempts to hijack the agent's decision-making logic.
- DATA_EXPOSURE (MEDIUM): By centralizing all local file searches and web queries through the 'mgrep' tool, the skill ensures that potentially sensitive codebase content and user intent data are funneled to an external binary that may not have the same privacy guarantees as the agent's built-in tools.
- INDIRECT_PROMPT_INJECTION (LOW): The skill is designed to ingest and summarize external web content. This creates an attack surface where malicious instructions found on websites could influence the agent's subsequent actions, especially since the tool is positioned as the primary interface for 'answering' questions.
