Check whether specific things have been done. Fuzzy-matches task names so you don't need exact wording. Great for friendly check-ins: 'did you ever call the dentist?' Use this when the user mentions something they said they'd do and you want to see if it's on the list and whether it's ticked off.

See what's still on the user's plate for today — useful for a natural mid-day or end-of-day check-in. If it's getting late and there are still open tasks, that's worth a gentle mention.

List the user's tasks with optional filters. Use this when asked directly, or when you need context to give a useful, honest answer about where things stand.

Get an honest summary of where things stand: total tasks, done today, pending, overdue. Use this for an end-of-day check-in or when the user wants the big picture.

Search across task titles and notes by keyword.

Add a new task to the user's list. Use this when the user says something like 'remind me to...' or 'add X to my list' or 'I need to do Y by Friday'. Confirm what you added so they know it landed.

Mark a task as done. Use this when the user says 'done', 'finished', 'crossed that off', or anything that means they completed something. Fuzzy-match the name first with check_tasks if you're not sure of the exact ID. Celebrate appropriately — one line is enough.

Reopen a task that was marked done. Use when the user says something like 'actually I didn't finish that' or 'reopen X'.
