Feature request: Tab completion for file paths in prompt input

Feature Request

Tab completion for file paths when typing in the Claude Code CLI prompt.

Current Behavior

When typing a path like ~/D and pressing Tab, nothing happens - no completion options are shown.

Desired Behavior

Tab completion should work like in a standard shell:

• ~/D<tab> → shows ~/Documents/, ~/Desktop/, ~/Downloads/, etc.
• ~/Documents/c<tab> → completes to matching files/directories

Use Case

When asking Claude to read, edit, or reference files, users need to type full paths manually. Shell-style tab completion would significantly improve the workflow, especially for deeply nested paths.

Environment

• macOS (though this would benefit all platforms)
• Claude Code CLI
