Use this skill when creating any new plugin for the trading pipeline. This includes IndicatorPlugin (technical indicators like RSI, MACD), SmoothingPlugin (Kalman filters, exponential smoothers), DataEnricher (sentiment, cross-asset features, options flow), and SignalFilter (attention reweighting, RL position sizers). Triggers on: 'add a new indicator', 'create a plugin', 'implement a Kalman filter', 'add sentiment from X', 'add a signal filter', or any task that mentions extending the pipeline with a new component using one of those four types. Do NOT use for: modifying core pipeline code (use quant-engine-dev), backtest workflows (use backtest-runner), fundamentals plugins (use fundamentals-plugin), event-driven exit filters (use event-filter), or the LLM validator (use llm-validator).
