SUMMARIZATION

Trello card comment threads into a Coda decision log

When a Trello card is moved to Done, condense its full comment thread into a single decision-log entry and append it as a new row in a Coda tracker.

What it does

When a card lands in your Done list, this workflow reads the card's entire comment history, asks an LLM to extract the decisions that were actually made, and writes one clean row into a Coda decision-log table. No more scrolling a 40-comment thread to remember why the team chose option B.

When to use it

Use it when card discussions hold the real reasoning behind a choice but that reasoning evaporates the moment the card is archived. Good for product squads, ops teams, and agencies who run decisions inside Trello threads and need a durable, searchable record in Coda.

How it works

  1. 1A Trello webhook fires when a card is moved into the configured Done list.
  2. 2The flow fetches the card's comments and metadata via the Trello API.
  3. 3An OpenAI call summarizes the thread into a decision, the rationale, and who decided.
  4. 4A filter skips cards with no substantive comments so the log stays clean.
  5. 5A new row is appended to the Coda tracker with the card title, decision, rationale, link, and date.
