Bayesian Workflow

Q: What is a Claude Code skill and how does the Bayesian Workflow skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Bayesian Workflow is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.

Use when performing Bayesian statistical analysis, building probabilistic models, or when the task involves prior specification, posterior inference, or predictive checks.

From the source SKILL.md

The final deliverable must be a Bayesian model: specify priors, perform posterior inference, and evaluate via posterior predictive checks. Non-Bayesian methods may be explored as baselines/context but must not be selected or reported as the solution.

What this skill does

Bayesian Workflow is a community-contributed Claude Code skill in the math-stats sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/bayesian-workflow/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when performing Bayesian statistical analysis, building probabilistic models, or when the task involves prior specification, posterior inference, or predictive checks.

Who uses this skill

The Bayesian Workflow Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
