View Pull Request Diff

View changes in a pull request including file diffs and change statistics.

When to Use

• User asks "what changed?" or "show me the changes"
• User wants to review code before approving
• User needs to understand the scope of modifications
• User wants to see a specific file's changes

How to Execute

Run:

aide pr diff [--pr <id|url>] [options]

Options

Flag	Description
--pr	PR ID or URL (auto-detected from branch if omitted)
--stat	Show summary statistics with line counts
--files	Show only changed file paths
--file	Show diff for a specific file path
--no-fetch	Skip auto-fetching missing branches (fetch by default)

Output Includes

1. Source and target branches
2. Changed files with +/- line counts (with --stat)
3. Full unified diff output (default)
4. File list only (with --files)

Best Practices

• Start with --stat to get an overview of changes
• Use --files to see which files were modified
• Focus on specific files with --file <path> for detailed review
• Auto-fetch is enabled by default - use --no-fetch if branches are already local

Progressive Review Pattern

# 1. Get overview of changes
aide pr diff --stat

# 2. See which files changed
aide pr diff --files

# 3. Review specific file
aide pr diff --file src/auth/login.ts
