File contents

This skill supports three task managers. Detect which is available with which todoist-cli things-cli task and use accordingly.

Todoist — `todoist-cli`

todoist-cli list                           # List today's tasks
todoist-cli list --project "Work"          # Tasks in a project
todoist-cli add "Task name" --due today --priority 2
todoist-cli add "Task" --project "Work" --label "urgent"
todoist-cli complete <task-id>
todoist-cli delete <task-id>
todoist-cli projects                       # List all projects
todoist-cli search "query"

Things 3 — `things-cli`

things-cli today                           # Today's tasks
things-cli list                            # All tasks
things-cli list --area "Work"
things-cli add "Task name" --when today --tag "urgent"
things-cli add "Task" --project "Project Name" --deadline "2026-03-01"
things-cli complete "Task name"
things-cli projects                        # List projects
things-cli areas                           # List areas

Taskwarrior — `task`

task list                                  # List pending tasks
task next                                  # Highest-priority next task
task add "Task name" due:tomorrow pri:H project:work
task add "Task" +tag1 +tag2
task <id> done                             # Complete a task
task <id> delete
task <id> modify priority:H
task project:work list                     # Filter by project
task +OVERDUE list                         # Overdue tasks
task summary                               # Project summary

Usage Guidelines

Check which tool is installed before running commands.
If multiple are installed, ask the user which they prefer or use the one matching their request context.
For natural language dates, Todoist and Things handle them natively; Taskwarrior uses due:YYYY-MM-DD or due:tomorrow.

Notes

Todoist requires API token configured via todoist-cli auth.
Things 3 requires macOS and the Things 3 app.
Taskwarrior stores tasks locally in ~/.task/.
