Explorer & Graph Explorer

One-Liner

The Explorer pages provide codebase navigation with file tree browsing, code dependency visualization, and real-time search capabilities.

Pain Points Solved

Pain Point	Current State	Explorer Solution
No code overview	Can't see codebase structure	File tree with hierarchical navigation
Hard to find files	Manual directory traversal	Search and filter with instant results
Unknown dependencies	Can't see relationships	Visual dependency graph with nodes/edges
No context preview	Open files blindly	File preview with syntax highlighting
Lost in large codebases	Can't navigate efficiently	Split view with resizable panes
