Implementation Reference

  • Handler for 'mail_get_total_inbox_count' tool: executes AppleScript via osascript to retrieve the total number of messages in the Mail inbox and returns the count.
    case 'mail_get_total_inbox_count':
      try {
        const command = `osascript -e 'tell application "Mail" to get count of messages of inbox'`;
        const { stdout, stderr } = await execAsync(command);
    
        if (stderr.trim()) {
          return {
            content: [
              {
                type: 'text',
                text: `Error getting total inbox count: ${stderr.trim()}`,
              },
            ],
          };
        }
    
        const totalCount = parseInt(stdout.trim());
    
        return {
          content: [
            {
              type: 'text',
              text: `Total messages in inbox: ${totalCount}`,
            },
          ],
        };
      } catch (error: any) {
        return {
          content: [
            {
              type: 'text',
              text: `Error executing total inbox count command: ${error.message}`,
            },

Behavior2/5

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

With no annotations provided, the description carries full burden but only states the basic operation without disclosing behavioral traits such as permissions needed, rate limits, freshness of data, or error conditions. It's minimal and lacks depth for a tool that likely interacts with user data.

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, clear sentence with no wasted words, making it highly efficient and easy to parse. It's front-loaded and appropriately sized for the tool's simplicity.

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 the tool's low complexity (0 params, no output schema), the description is minimal but adequate for basic understanding. However, without annotations or output details, it fails to provide complete context for safe and effective use, such as what the count represents or any limitations.

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 tool has 0 parameters, and schema description coverage is 100%, so no parameter documentation is needed. The description doesn't add param info, but this is acceptable given the lack of inputs, aligning with the baseline for zero parameters.

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 ('Get') and resource ('total message count in inbox'), making the tool's purpose immediately understandable. However, it doesn't differentiate from its sibling 'mail_get_inbox_count', which appears to serve a similar function, preventing a perfect score.

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 like 'mail_get_inbox_count' or other mail-related tools. It lacks context about prerequisites, timing, or comparison with siblings, leaving usage decisions ambiguous.

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