Updates beliefs systematically based on new evidence using probabilistic reasoning and Bayes' Theorem.
The Bayesian Reasoning skill for Claude Code provides a rigorous framework for decision-making under uncertainty by treating beliefs as probabilities that evolve with new data. It helps developers move beyond binary thinking by incorporating prior knowledge (base rates) and calculating how much new evidence should realistically shift their confidence. This skill is essential for high-stakes analysis where intuition often fails, such as interpreting rare test results, diagnosing complex system failures, or estimating project delivery timelines based on historical performance.
