Automated summary

Fetches cards from a specific Trello list and returns them as a structured array and a markdown view.

Strengths

Single-list fetch by ID is straightforward
Optional filtering by last activity date
Two markdown rendering formats (compact and detailed)
Cards sorted by most recent activity

Limitations

Requires the list ID to be known beforehand
Does not handle multiple lists or entire boards
The 'since' filter is inclusive, may need adjustment for strict past filtering

When to use it

Use this skill to get a formatted snapshot of a specific Trello list, for example in daily reports or progress tracking.

When not to use it

Avoid this skill when you need to traverse multiple lists or boards; instead use a resolution skill like 'trello-board-resolver'.

Security analysis

Safe

Quality score88/100

The skill only uses the allowed mcp__trello__get_cards tool to fetch data from Trello. It performs no destructive actions, does not make external network calls, and does not execute arbitrary code. Inputs are validated to only affect the fetch operation, and there is no risk of data exfiltration or system harm.

No concerns found

Examples

Compact list snapshot

Fetch the cards from Trello list ID '5f3c...' and show them in compact markdown format.

Detailed snapshot with since filter

Retrieve the cards from Trello list 'abc123' that have been active since '2025-03-01T00:00:00Z' and display them in detailed markdown, labeling the list as 'Today'.

trello-list-snapshot

Name: Trello List Snapshot
Author: Skills Guide Bot

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:

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

Behavior

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.
Sort the returned cards by date_last_activity descending.

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>

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).

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/trello-list-snapshot-mrwakbn8' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/trello-list-snapshot-mrwakbn8/download' --output '.skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md.part' && mv '.skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md.part' '.skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

Tools declared by the author (check availability in your agent): mcp__trello__get_cards

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md' && test -s '.skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/trello-list-snapshot' && cp -R '.skill-downloads/trello-list-snapshot-mrwakbn8' '.claude/skills/trello-list-snapshot'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation

openskills install './.skill-downloads/trello-list-snapshot-mrwakbn8'

openskills read 'trello-list-snapshot-mrwakbn8'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/trello-list-snapshot-mrwakbn8/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
