Trello Stale-Card Watcher

Each morning, surfaces Trello cards that haven't moved in too long — and nudges them with a comment.

Lists your Trello board's open cards every morning, finds the ones that haven't had any activity in a while, and adds a 'stale, please review' comment. Keeps your board honest without you having to spelunk through it.

Every weekday at 9 AM, list the open cards on my Trello board <board id>. For any card that hasn't been updated in 7 days, add a comment: "Stale — please review or move to Parking Lot." Then email me a one-line summary of how many cards you nudged.

What you get.

Trello: 3 stale cards nudged

Nudged three stale cards on the Roadmap board: "Backfill old user roles" (last touched 9 days ago), "Investigate billing edge case" (12 days), and "Refactor onboarding flow" (8 days). Each got a comment asking for a review or move. The rest of the board has been touched within the last week.

Make it yours.

A few directions other people have taken this agent.

Change the staleness threshold — 3 days, 7 days, 14 days.
Move stale cards instead of commenting — drop them into a 'Parking Lot' list.
Filter by label — only watch cards tagged 'in progress'.
Pipe a daily summary to email or Slack instead of leaving comments.
Run weekly instead of daily.

What it costs.

About a cent per run. Trello reads + comments are free; the model writes one comment per stale card. Building and previewing are free, always.

Build this in five minutes.
