Troubleshooting

Issue	Solution
"OmniFocus is not running"	Launch OmniFocus first
"Project not found"	Check exact project name with `projects` command
"Context not found"	Check exact context name with `contexts` command
"Multiple matching tasks"	Use more specific task name
Task not found	Task may already be completed or deleted
"Invalid date"	Check date format against Date Formats section
"Invalid range"	Use: today, tomorrow, week, overdue

Limitations

Requires OmniFocus 4 running on macOS
Cannot modify completed tasks
Project and context names must match exactly
Task matching is case-insensitive but uses substring matching
Repetition rules use OmniFocus's iCalendar syntax
