Individual skill
manifoldbt-backtester
Runs a declarative strategy spec over OHLCV bars with the manifoldbt Rust engine, pairs the fill log into round trips, and emits the eight inputs the backtest-expert skill scores. Use when the user wants to execute a backtest, measure a rule they have described, obtain win rate / average win / average loss / max drawdown from real bars, or feed backtest-expert with measured numbers instead of estimates.

# manifoldbt Backtester Skill
## Purpose
Execute what `backtest-expert` teaches. That skill grades a backtest on five
dimensions, and its prerequisites say "metrics are user-provided": it scores
numbers it never produces. This skill produces them. It runs a strategy over
real bars and returns the eight inputs its evaluator asks for.
The two chain in one direction: spec, run, evaluate.
## When to Use This Skill
- A user describes a rule and wants it measured
