Args:
    checklist_id (str): The ID of the checklist to retrieve

Returns:
    Dict: The checklist data

Input Schema

checklist_idYes

Implementation Reference

  • The MCP tool handler for 'get_checklist', a thin wrapper delegating to ChecklistService.
    async def get_checklist(checklist_id: str) -> Dict:
        """
        Get a specific checklist by ID.
    
        Args:
            checklist_id (str): The ID of the checklist to retrieve
    
        Returns:
            Dict: The checklist data
        """
        return await service.get_checklist(checklist_id)
  • Registration of the 'get_checklist' tool in the MCP server.
    mcp.add_tool(checklist.get_checklist)
  • Core implementation in ChecklistService, performing the Trello API GET request.
    async def get_checklist(self, checklist_id: str) -> Dict:
        """
        Get a specific checklist by ID.
    
        Args:
            checklist_id (str): The ID of the checklist to retrieve
    
        Returns:
            Dict: The checklist data
        """
        return await self.client.GET(f"/checklists/{checklist_id}")
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool retrieves data, implying a read-only operation, but doesn't clarify aspects like authentication requirements, error handling (e.g., what happens if the ID is invalid), rate limits, or response format details beyond 'Dict'. This is a significant gap for a tool with zero annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately concise and well-structured, with a clear purpose statement followed by 'Args' and 'Returns' sections. Every sentence adds value, and there's no redundant information. It could be slightly improved by integrating the sections more seamlessly, but it's efficient and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's low complexity (one parameter, no nested objects) but lack of annotations and output schema, the description is minimally adequate. It covers the basic operation and parameter semantics but misses behavioral details like error cases or response structure. For a simple read tool, this is borderline viable but leaves gaps in completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaningful context for the single parameter by specifying that 'checklist_id' is used to retrieve a specific checklist, which clarifies its role beyond the schema's basic type definition. With 0% schema description coverage and only one parameter, this compensation is effective, though it could be enhanced with details like ID format or sourcing.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with a specific verb ('Get') and resource ('checklist by ID'), making it immediately understandable. However, it doesn't differentiate this tool from potential sibling read operations like 'get_board' or 'get_card', which might also retrieve specific items by ID, leaving room for improvement in distinguishing its specific scope.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a valid checklist ID), compare it to sibling tools like 'get_checklists' (if it existed) for listing multiple checklists, or specify use cases. This lack of contextual direction leaves the agent to infer usage from the tool name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
