Trello Card Assistant with Codex

Once the request type is decided the job is mechanical: apply the labels your playbook maps to it, add that type's checklist items in playbook order, leave one comment naming what is absent. Codex moves fast through work shaped like that, taking the board reads and card writes in its stride. Nothing here needs planning, it needs doing accurately.

Live demo

Watch it work before it's live

Run a staged conversation — no account needed. The agent handles it for real while a simulated world answers its tool calls; nothing touches real accounts, and nothing is actually sent.

New site build: Kaselo Bakery, six pages, launch 14 Oct

They want it live by 14 October because the second shop opens that week. Day to day contact is Nuno Cardoso, nuno@kaselo.pt.

  3. Board playbook

    Your board in your own words - which list is the intake, what kinds of request land there, the labels and checklist each type gets, where a card moves next, what counts as a complete request, and which cards are worth a Slack ping.

A considered pairing

Why Codex for this agent

Checklist in playbook order

Items go on in the order you wrote them, every time, with none of them ticked. Exact repeatable writes are where a fast harness is at its most useful.

Answers while the card is warm

A card added from a phone at 23:12 has its question on it before the person who added it has put the phone down.

Good to know

Before you fork

What if Trello errors after the label but before the comment?

You get a failed run carrying the error, and the label that already landed stays on the card. You get a card with a label and no checklist, which is visible on the board rather than hidden somewhere. There is no automatic retry, so the thing to watch is repeated failures in your run history, which usually means a revoked token rather than a one off.
