Cross-Platform Codebase Exploration

Repository Locations

Other platform repos are siblings of the root iOS repo (not worktrees):

Finding Repos (Worktree-Safe)

If working in a worktree, first find the root iOS repo:

# Get root repo path (works in both root and worktree)
# --porcelain output is stable for scripting; first entry is always the main worktree
ROOT=$(git worktree list --porcelain | head -n

Before Exploring

Each repository contains a CLAUDE.md at its root. Read it first to understand architecture and conventions.

Branch Sync Procedure

Before exploring code:

1. Navigate to repo and check current state:

   cd "$WEB_REPO"  # or $ANDROID_REPO
   git status --short
   git branch --show-current

2. If uncommitted/unstaged changes exist → ask the user: stash them, discard, or abort?

3. Determine target branch:

   • If user specified a PR → check out that PR's branch
   • If on develop (Web) main (Android) or trunk (iOS) → pull latest
   • If on a different branch → ask the user: switch to main/trunk, or stay on current branch?

4. Sync the branch:

   git checkout <branch>  # if switching
   git pull

What to Focus On

When comparing or describing implementations:

• Logic flow and feature architecture
• State transitions
• DTOs / data models
• API usage, endpoints, request/response structures
• Feature flags and configuration patterns
• Cross-platform differences and similarities

Avoid language-specific syntax unless necessary to explain behavior.

Example Queries

• "How does iOS handle Up Next syncing?"
• "Compare podcast following between Android and Web"
• "What endpoints does the Server use for Up Next sync?"
• "How are feature flags structured on iOS vs Android?"
