# Generating Patches Generate portable git patch files from codebase modifications, enabling users to apply Claude's edits to their local repositories. ## When to Use Activate after modifying files in an uploaded codebase when the user needs to transfer changes back to their local environment. Typical workflow: user uploads zip → Claude edits files → this skill exports changes as a patch. ## Prerequisites Verify git is available and the working directory is a git repository (or can be initialized as one): ```bash git status 2>/dev/null || git init ``` If working with an uploaded codebase that lacks git history, initialize and create a baseline commit before making edits: ```bash git init git add -A git commit -m "Baseline: original uploaded state" ``` ## Generating the Patch After completing edits, generate a unified diff: ```bash # For uncommitted changes (working tree modifications) git diff > /mnt/user-data/outputs/changes.patch # If changes are staged but not committed git diff --cached > /mnt/user-data/outputs/changes.patch # For both staged and unstaged git diff HEAD > /mnt/user-data/outputs/changes.patch ``` For committed changes (preserves commit messages and metadata): ```bash # All commits since baseline git format-patch --stdout baseline..HEAD > /mnt/user-data/outputs/changes.patch # Or specify number of commits git format-patch --stdout -n 3 > /mnt/user-data/outputs/changes.patch ``` ## Handling Edge Cases **Binary files**: Git diff excludes bina...
