Strategy Pivot Designer Overview Detect when a strategy's backtest iteration loop has stalled and propose structurally different strategy architectures. This skill acts as the feedback loop for the Edge pipeline (hint-extractor - concept-synthesizer - strategy-designer - candidate-agent), breaking out of local optima by redesigning the strategy's skeleton rather than tweaking parameters. When to Use - Backtest scores have plateaued despite multiple refinement iterations. - A strategy shows signs of overfitting (high in-sample, low robustness). - Transaction costs defeat the strategy's thin ed…
