What problem does it solve? Options traders and risk teams need consistent, contract-compliant Greeks calculations for their positions, plus a reliable way to verify that authoritative pricing components are actually connected rather than silently falling back to stub data. ## Core Features & Use Cases - Greeks Calculation: Calls the authoritative calc_greeks tool to produce a GreeksProfile with portfolio-level delta, gamma, vega, and theta for a given underlying and as-of date. - Threshold Validation: Checks whether portfolio delta exceeds brainstorm-defined constraints before results are accepted. - Optional Backtesting: Runs the authoritative options backtest component when available, using run_options_backtest_stub only for explicit fixture validation and never as production PnL. - Use Case: After a volatility surface is built by the upstream skill, refresh Greeks for a GC options position, verify delta stays within limits, and persist results to artifacts/options/{strategy_name}/greeks.json for the risk group. ## Quick Start Calculate the Greeks for my GC options position as of 2026-06-27 with the current spot price and check whether the portfolio delta exceeds the configured threshold.
