Backtest Diagnosis

Overview

Use this skill when a user reports that a backtest failed, raised an error, or produced poor results.

Diagnostic Workflow

1. Read existing artifacts: use read_file to inspect artifacts/metrics.csv, equity.csv, and trades.csv
2. Read the code: use read_file to inspect code/signal_engine.py and config.json
3. Classify the issue: determine the root cause using the error taxonomy below
4. Apply the fix: use edit_file to modify the code, then rerun the backtest
5. Verify the fix: use read_file to inspect the new metrics.csv
