Market Strategy Tactician

This tool acts as a senior crypto strategist, taking market_context (price action and technical structure), sentiment_context (narratives and positioning), optional portfolio_state (current holdings and risk parameters), and optional time_horizon (intraday, swing, or position). It synthesizes these into a high-conviction tactical strategy briefing, including views, scenarios, and risk management guidance. The model must produce only a single JSON object, with no extra keys, that strictly validates against the system-provided structured output schema for this tool.
