Setting Up a Reproducible Analysis

Overview

Ensure the analysis happens in an isolated workspace that another person (or future you) can reproduce exactly: same code, same environment, same seed, same immutable input data.

Core principle: A result you cannot reproduce is not a result. Set up reproducibility before you run anything.

Announce at start: "I'm using the setting-up-reproducible-analysis skill to set up an isolated, reproducible workspace."

Step 0: Detect Existing Isolation

Before creating anything, check whether you're already in an isolated workspace.

GIT_DIR=$(cd "$(git rev-parse --git-dir)" 2>/dev/null && pwd -P)
GIT_COMMON=$(cd "$(git rev-parse --git-common-dir)" 2>/dev/null && pwd -P)
BRANCH=$(git branch --show-current)
