Trello and AI agents
A board takes an evening to set up and looks right for about a week. Six months later there are fourteen cards in «Doing», half of them are titles with nothing underneath, and nobody remembers what is actually left on any of them. The agent works on the boards you open to it and keeps them honest: a card should describe the work that remains, and anything stuck should be visible without someone going to look for it.
What an agent does in Trello
- Works on the boards you open to it, and doesn't look at the rest.
- Turns a two-line request into a real card: the title is an outcome, the description holds what's known, the checklist holds what's left.
- Surfaces cards that have sat in a column longer than the time you set.
- Checks a card's title against its checklist and says when the two stopped agreeing.
- Runs the board review: what has stalled, what has no owner, what looks finished and was never closed.
Processes that run themselves
A playbook isn't a button — it's a process with a condition that starts it. In Trello that condition usually comes from the board itself: a card that stops moving, a request arriving, the day you set aside for a review.
A card stops moving
A card has sat in a column longer than the time you set
- Find what last happened on the card, and when
- Ask the owner in a comment what is actually left
- Rewrite the checklist to match the answer, and show you the change before making it
- Put the card into the review if no answer arrives in time
A request becomes a card
A request arrives that ought to become a card
- Work out what outcome is being asked for, rather than what topic was named
- Write the title as that outcome and build the description from what's known
- List separately what's missing before anyone can start
- Drop it in the intake list with no assignee — the column and the date are yours
The board review
The day of the week you set aside for a board review
- Collect the cards with no movement, no owner and no date
- Flag the ones where the title and the checklist say different things
- Propose what to close or archive as a list, not as an action
Where the agent stops
- It doesn't set priorities: which card matters more is yours to decide — it shows you what's happening, it doesn't rank it.
- It doesn't reassign someone else's card: changing the member on a card is a question first, not an action.
- A card it can't write clearly comes back to you as a question rather than a guess.
- The board is only as true as what people record on it, and when the agent is inferring rather than reading, it says so.
FAQ
Will it move and archive my cards?
Move, only where you allowed it and only by a rule you set yourself. Archive, no: it brings you the list of what looks finished and waits. Trello's archive is recoverable, but a card nobody can find again costs more than an extra line in a review.
Does it need access to all my boards?
No. Trello grants access board by board: you open the ones you want and the rest don't exist for the agent. You can change that list whenever you like.
Our board is loose — half the columns mean nothing and almost nothing has a due date. Will this still work?
Yes, and that's usually where it starts. The agent needs two things from you: which column means «in progress», and how long a card is allowed to sit there. Labels, dates and templates can come later, if you ever want them at all.
What if the title says one thing and the checklist says another?
It shows you the mismatch and asks which one is right, instead of picking. Usually it isn't an error — it's work that changed on the way, and only the person doing it knows how.
