Implementation Reference

  • Core handler function that executes the API POST request to the Basecamp endpoint to complete a card step.
    async completeCardStep(projectId: string, stepId: string): Promise<any> {
      const response = await this.client.post(`/buckets/${projectId}/todos/${stepId}/completion.json`);
      return response.data;
    }
  • MCP server handler case that calls the BasecampClient method and formats the MCP response.
    case 'complete_card_step': {
      await client.completeCardStep(typedArgs.project_id, typedArgs.step_id);
      return {
        content: [{
          type: 'text',
          text: JSON.stringify({
            status: 'success',
            message: 'Step marked as complete'
          }, null, 2)
        }]
      };
    }
  • Input schema definition for the complete_card_step tool, specifying required project_id and step_id parameters.

Behavior2/5

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

No annotations are provided, so the description carries full burden. It implies a mutation ('Mark as complete') but doesn't disclose behavioral traits like whether this is idempotent, requires specific permissions, affects other data (e.g., triggers notifications), or returns confirmation. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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

Conciseness5/5

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

The description is a single, efficient sentence with zero waste. It's front-loaded with the core action and resource, making it easy to parse. Every word earns its place without redundancy or fluff.

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

Completeness2/5

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

Given this is a mutation tool with no annotations and no output schema, the description is incomplete. It lacks details on behavioral context (e.g., side effects, error conditions), usage prerequisites, and what happens upon completion. For a tool that modifies state, more information is needed to guide safe and effective use.

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

Parameters3/5

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

Schema description coverage is 100%, with both parameters ('project_id' and 'step_id') clearly documented in the schema. The description adds no additional meaning beyond implying these IDs are needed to identify the step. Baseline 3 is appropriate as the schema does the heavy lifting.

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 action ('Mark') and resource ('a card step'), specifying it as 'complete'. It distinguishes from siblings like 'complete_card' (which marks an entire card) and 'get_card_steps' (which retrieves steps). However, it doesn't explicitly contrast with all siblings, such as 'update_card' which might also modify step status.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., step must exist, user must have permissions), exclusions (e.g., cannot complete already completed steps), or related tools like 'get_card_steps' to check status first. The description alone offers no usage context.

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