# Trello Integration Skill

The Trello Integration Skill provides a seamless connection between the AI agent and the user's Trello account. It empowers the agent to autonomously fetch existing boards and lists, and create new task cards on specific boards based on user prompts.

## Features
- **Fetch Boards**: Retrieve a list of all Trello boards the user has access to, including their Name, ID, and URL.
- **Fetch Lists**: Retrieve all lists (columns like "To Do", "In Progress", "Done") belonging to a specific board.
- **Create Cards**: Automatically create new cards with titles and descriptions in designated lists.

---

##  Setup & Prerequisites

To use this skill locally, you need to provide your Trello Developer API credentials.

1. Generate your credentials at the [Trello Developer Portal (Power-Ups Admin)](https://trello.com/app-key).
2. Create an API Key.
3. Generate a Secret Token (Read/Write access).
4. Add these credentials to the project's root `.env` file:

```env
# Trello Integration
TRELLO_API_KEY=your_api_key_here
TRELLO_TOKEN=your_token_here
```

---

##  Usage & Architecture

The skill utilizes standalone Node.js scripts located in the `.agent/skills/trello_skill/scripts/` directory.

### 1. List All Boards
Fetches all boards for the authenticated user to determine the correct target `boardId`.

**Execution:**
```bash
node .agent/skills/trello_skill/scripts/list_boards.js
```

### 2. List Columns (Lists) in a Board
Fetches the lists inside a specific board to find the exact `listId` (e.g., retrieving the ID for the "To Do" column).

**Execution:**
```bash
node .agent/skills/trello_skill/scripts/list_lists.js <boardId>
```

### 3. Create a New Card
Pushes a new card to the specified list.

**Execution:**
```bash
node .agent/skills/trello_skill/scripts/create_card.js <listId> "<Card Title>" "<Optional Description>"
```
*(Always wrap the card title and description in double quotes to prevent bash argument splitting).*

##  AI Agent Workflow

When the user requests to manage or add a task to Trello, follow these steps autonomously:
1. **Identify the Target**: If the target `listId` is unknown, first run `list_boards.js` to identify the correct `boardId`, then execute `list_lists.js <boardId>` to retrieve the corresponding `listId` (e.g., for "To Do").
2. **Execute Command**: Run the `create_card.js <listId> "Task Title" "Task Description"` script.
3. **Report Back**: Confirm the successful creation with the user and provide the direct URL to the newly created Trello card.

REQUIRED CONTEXT

  • user request to manage or add Trello task

TOOLS REQUIRED

  • code_execution

ROLES & RULES

  1. Identify the Target: If the target listId is unknown, first run list_boards.js to identify the correct boardId, then execute list_lists.js <boardId> to retrieve the corresponding listId.
  2. Execute Command: Run the create_card.js <listId> "Task Title" "Task Description" script.
  3. Report Back: Confirm the successful creation with the user and provide the direct URL to the newly created Trello card.

EXPECTED OUTPUT

Format
plain_text
Constraints
  • confirm success
  • provide card URL

SUCCESS CRITERIA

  • Fetch boards and lists autonomously
  • Create new cards in specified lists
  • Confirm creation and provide card URL

FAILURE MODES

  • Missing TRELLO_API_KEY or TRELLO_TOKEN in .env
  • Invalid boardId or listId
  • Bash argument splitting without double quotes

CAVEATS

Dependencies
  • Trello API credentials (API_KEY and TOKEN) in .env file
  • Node.js environment to execute scripts
  • Directory structure with scripts in .agent/skills/trello_skill/scripts/
Missing context
  • AI agent framework or environment for executing scripts (e.g., tool-calling setup).
  • Handling for cases with multiple boards or ambiguous list names.
Ambiguities
  • Script name inconsistency: usage refers to 'list_boards.js' but code file is labeled 'list_board.js'.
  • Workflow assumes AI agent can autonomously execute bash/node commands without specifying the execution mechanism.

IMPROVEMENT SUGGESTIONS

  • Standardize script filenames (e.g., rename to 'list_boards.js' consistently).
  • Add a section on integrating with AI agent tool-calling (e.g., define tools for each script).
  • Enhance create_card.js to support optional parameters like due dates, labels, or assignees.
  • Include example user prompts and full workflow traces.
