Trello Card Creation
Send records or feedback into a chosen Trello board and list as actionable cards.
What it adds
A server-side path from an in-app record to a card on a configured Trello board and list, with a stored card reference.
What your agent is told to do

What your agent is told to do
5-
1
Have an administrator choose the board and list during setup, and verify access by performing a real read on both before saving the connection. A board identifier accepted without verification fails on the first real submission.
-
2
Re-resolve the target list at creation time and handle the case where it has moved, been archived, or been deleted: fall back to a configured default list and raise a configuration warning rather than dropping the card.
-
3
Compose the card on the server from the originating record, with a link back into the app and only the context a board member is entitled to see. Trello boards are frequently public or widely shared, so treat everything placed on a card as published.
-
4
Key each submission by the originating record and check for an existing card reference before creating, so retries after a timeout do not scatter duplicate cards across the list.

GitHub Issue Creation, GitLab Issue Creation, Linear Issue Creation, Jira Ticket Creation, and Asana Task Creation are siblings. Capture, redaction, deduplication, and reference storage belong to the shared path; this brief owns only Trello's board and list resolution and its field mapping.
Edge cases it handles

Edge cases it handles
8- Board and list access must be verified at setup rather than assumed. The connected account may see the board but lack permission to add cards, which only surfaces when a real write is attempted.
- Lists are moved, archived, and deleted by board members without telling the app. Detect the missing target, use a configured fallback, and notify an administrator instead of failing the submission silently.
- Retries and double submissions must converge on one card. Persist the created card reference before acknowledging the job and check it on every attempt.
- Labels, members, due dates, and attachments must be resolved against the board at creation time. An unknown label or a member who has left the board should be omitted with a note, not treated as a fatal error.
- A board may be public or shared with people outside the organisation. Never place customer personal data, internal identifiers, credentials, or log excerpts on a card; summarise and link back into the app for the detail.
- The stored credential will expire or be revoked when a member leaves. Distinguish authentication failure from a transient error, hold the queue, and prompt an administrator to reconnect.
- Rate limiting requires exponential backoff with jitter and a bounded retry count, with a dead-letter path for cards that repeatedly fail.
- When Trello is unavailable, record the item in the app and create the card afterwards, so the user sees their submission accepted rather than an error.

Definition of done
9- Board and list access is verified with a real request before the connection is saved.
- A moved, archived, or deleted list falls back to a configured default and warns an administrator.
- Retried submissions produce exactly one card.
- Labels, members, due dates, and attachments are resolved at creation time and unknown values are omitted rather than fatal.
- No customer personal data, credentials, or internal identifiers appear on a card.
- Credential expiry queues submissions and prompts a reconnection.
- A Trello outage leaves the submission recorded in the app and created later.
- The feature matches the existing design system.
- No existing functionality is broken.

Direct Messages
Direct Messages
Let two users hold a private conversation inside the app instead of leaving to email.
What it does
One-to-one private threads with message history, per-conversation unread counts, and blocking.
How it works
- 1 Build the conversation list, the thread view, and the unread badge. Keep the first version to one-to-one threads only and defer group conversations, reactions, threading, and file attachments rather than shipping all of them half-finished.
- 2 Reuse the app's existing Read and Unread State and Notification Center rather than inventing a second unread mechanism and a second alert path. A message notification should sit alongside every other notification the user gets.
- 3 Reuse the composer, mention handling, and rendering rules from Comments and Mentions instead of writing a second message editor with subtly different escaping.

Voice Notes
Voice Notes
Say it instead of typing it, and attach the recording where the conversation is.
What it does
In-app recording of short audio notes attached to a record, comment, or message.
How it works
- 1 Add recording to the places where people already leave text, most likely alongside Comments and Mentions, so a voice note is another kind of comment rather than a separate feed nobody checks.
- 2 Store the recording through the app's existing file upload path so a voice note inherits the same retention and access rules as any other attachment on the record, and disappears with the record when it is deleted.
- 3 Show a live duration and a simple level meter while recording, and let the user review and discard before it is sent. Nobody should be committed to a recording the instant they stop.

Assign Ownership
Assign Ownership
Make it obvious who is responsible for each record.
What it does
An assignee on records, with a picker, notifications on change, and a history of who owned what.
How it works
- 1 Add a nullable assignee to the relevant records. Unassigned is a real, valid state — do not force a default owner just to avoid the null.
- 2 Restrict the picker to users who can actually access the item, and validate that server-side as well as filtering the list.
- 3 Notify the new assignee when they are assigned by someone else, and record every change with the actor and timestamp.

It inspects, then implements
Your agent reads your existing app first, then adds the feature to fit it.
Works with your stack
These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
Need it tighter than that? Customize the feature and tell it exactly what you're running.
