Open a saved Pine Script by name
AI agents call pine_open to retrieve information from TradingView MCP Jackson without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool opens/retrieves an existing saved Pine Script by name, which is a read operation - it fetches and displays an existing resource without modifying data. The blast radius is low as it only affects what is displayed in the TradingView interface.
