name: trello-list-snapshot description: > Fetch the cards in a single Trello list (optionally filtered by activity date with since) and return them as both a structured array and a markdown-formatted view. Use this whenever a skill needs the contents of a specific Trello list by ID. user-invocable: false allowed-tools: mcp__trello__get_cards

trello-list-snapshot

Single-list fetch + format. Reusable building block for any Trello reporting skill.

Inputs

• list_id (required) — Trello list ID.
• since (optional) — ISO 8601 UTC timestamp. When provided, only cards whose date_last_activity is >= since are returned (server-side filter via the Trello-MCP since parameter).
• format (optional, default detailed) — compact or detailed. Controls the markdown rendering; the structured array is unaffected.
• label (optional) — a short label for the list (e.g. "Doing") used in the markdown heading. Defaults to "List".

Output

Return both:

1. A structured array of cards, each with: id, name, desc, due, due_complete, labels, url, member_ids, date_last_activity.
2. A markdown block. Sort by date_last_activity descending (most recent first). If the list is empty after filtering, render _(no cards)_.

Behavior

1. Call mcp__trello__get_cards(list_id=<list_id>, since=<since>?). Omit since from the call when it is not provided — do not pass empty string or null.

2. Sort the returned cards by date_last_activity descending.

3. Render markdown:

   detailed:

   ### <label> (<n> cards)
   - **<name>** — _<date_last_activity>_
     - Due: <due> · Labels: <label-names>
     - Members: <member_ids joined>
     - <url>
     - <first line of desc, truncated to 200 chars> (if non-empty)
   

   compact:

   ### <label> (<n> cards)
   - <name> · <date_last_activity> · <url>
   

4. Return the structured array and the markdown string to the caller.

Notes

• The Trello-MCP since filter is inclusive (>=). Callers that want a strict "after" should pass since one millisecond past the cutoff.
• date_last_activity is "any activity," not specifically a list move. The daily-summary skill explains why this is an acceptable proxy for "completed since" when reading the Done list.
• Do not call list_boards or list_lists from this skill; the caller is expected to have resolved the list_id already (e.g. via trello-board-resolver).
