📁 File Organizer

Organize files in directories with AI assistance. Remembers your preferences.

USAGE:
  bun cli.ts [directory]           Organize a directory
  bun cli.ts                       Interactive mode
  bun cli.ts --status              Show agent status
  bun cli.ts --reset               Reset agent (forget preferences)
  bun cli.ts -h, --help            Show this help

OPTIONS:
  -s, --strategy TYPE    Organization strategy (type, date, project)
  --dry-run              Preview changes without moving files

EXAMPLES:
  bun cli.ts ~/Downloads                  # Organize Downloads
  bun cli.ts ~/Documents --strategy=date  # Organize by date
  bun cli.ts ./messy-folder --dry-run     # Preview only
  bun cli.ts .                            # Organize current directory

STRATEGIES:
  type      Group by file extension (images/, documents/, code/)
  date      Group by date (2024/, 2025/ or by month)
  project   Group by project (inferred from content)
  (none)    AI decides best approach

SAFETY:
  - Always previews changes before executing
  - Never deletes files (only moves)
  - Creates directories as needed

PERSISTENCE:
  The agent learns your organizational preferences over time.
