What problem does it solve? It gives you a disciplined workflow for Coinbase spot crypto research and strategy backtesting, resolving product IDs, fetching market data with quality checks, and producing execution-grade backtest artifacts without touching unsupported venues or live trading. ## Core Features & Use Cases - Coinbase Market Data: Resolve spot product IDs, fetch OHLCV candles, order books, latest trades, and best bid/ask with source-quality metadata. - Strategy Backtesting: Run single-product trend-following and mean-reversion backtests on Coinbase OHLCV data, then inspect job status and trade logs by job_id. - Artifact Export: Validate and export execution-grade strategy artifacts for the internal Coinbase paper ledger, with blocking on data-quality failures. - Use Case: Ask for a mean-reversion backtest on BTC-USD over the last year; the skill resolves the product, runs the backtest with execution-venue data policy, reports Sharpe, drawdown, and coverage quality, and exports an artifact only if the run is execution grade. ## Quick Start Ask the assistant to backtest a Coinbase spot strategy, for example: run a mean-reversion backtest on BTC-USD 1-hour candles for the past year and show the metrics and data quality.
