PROJECT MANAGEMENT

Auto-reassign aging Trello cards to an available owner

When a Trello card crosses its idle threshold, this workflow checks the current owner's calendar for availability and reassigns the card to the next free teammate.

What it does

This workflow watches for Trello cards that have gone idle past a set number of days and decides whether the current owner can still act on them. It checks that owner's Google Calendar for out-of-office or heavy booking, and if they are unavailable it reassigns the card to the next teammate whose calendar is clear, then announces the handoff in Slack.

When to use it

Use it when cards stall because the assignee is on leave, in back-to-back meetings, or overloaded. It keeps work moving without a manager manually rebalancing the board.

How it works

  1. 1A daily schedule starts the sweep across the target board.
  2. 2The workflow fetches cards whose last activity exceeds the idle threshold from Trello.
  3. 3For each card it reads the assignee's Google Calendar to gauge availability over the next few days.
  4. 4A logic step decides: if the owner is free, leave the card; if not, pick the next available teammate from the pool.
  5. 5The card is reassigned to the chosen owner in Trello.
  6. 6A handoff message is posted to Slack tagging the old and new owners.
