Get Gemini CLI help information and available commands.
AI agents call gemini_help to retrieve information from Gemini CLI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply queries and returns help documentation about available Gemini CLI commands. It has no side effects, does not modify data, does not execute user code, and does not delete or move resources. It is a read-only information retrieval operation with minimal blast radius if misused.
