Implementation Reference

  • index.js:314-324 (registration)
    Registers the connect_twilio tool with its name, description, and input schema in the list of tools returned by ListToolsRequestHandler.
      name: 'connect_twilio',
      description: 'Connect Twilio account credentials',
      inputSchema: {
        type: 'object',
        properties: {
          twilio_sid: { type: 'string', description: 'Twilio Account SID' },
          twilio_token: { type: 'string', description: 'Twilio Auth Token' }
        },
        required: ['twilio_sid', 'twilio_token']
      }
    },
  • Handler for connect_twilio tool: sets up a POST request to the Vavicky backend API at /twilio/oauth with the provided twilio_sid and twilio_token to connect the Twilio account.
    case 'connect_twilio':
      url = `${this.baseUrl}/twilio/oauth`;
      method = 'POST';
      body = {
        sid: args.twilio_sid,
        token: args.twilio_token
      };
      break;
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 action without behavioral details. It doesn't disclose what 'connect' entails (e.g., authentication setup, persistence, error handling), rate limits, or side effects, leaving significant gaps for a credential-handling tool.

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 no wasted words. It's front-loaded and appropriately sized for its purpose, making it easy to parse quickly.

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 no annotations, no output schema, and a credential-handling tool with potential security implications, the description is incomplete. It lacks details on what happens after connection (e.g., success response, error cases), making it inadequate for 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%, so the schema fully documents both parameters. The description adds no additional meaning beyond implying these credentials are needed for connection, which aligns with the schema. Baseline 3 is appropriate as the schema handles parameter documentation.

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 verb 'connect' and resource 'Twilio account credentials', making the purpose understandable. It doesn't explicitly distinguish from sibling tools like 'disconnect_twilio', but the action is specific enough to understand what it does.

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 'disconnect_twilio' or other Twilio-related tools. There's no mention of prerequisites, context, or exclusions for usage.

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