Behavior3/5

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

With no annotations, the description carries the full burden. It clearly states a send action, but does not disclose any side effects, security implications (e.g., exposure of auth_token), rate limits, or what happens after sending. However, the core behavior is straightforward and not misleading.

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 sentence, front-loaded with the core action and channels. Every word earns its place; no fluff or redundancy.

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?

The description is too brief given the tool has 5 parameters and no output schema. It does not explain return values, error conditions, prerequisites (e.g., valid Twilio account), or the fact that auth_token is sensitive. An agent might need more context to use this tool effectively.

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 60% (three of five parameters have descriptions). The tool description does not add any additional parameter semantics beyond what's in the schema. Baseline score of 3 is appropriate since the schema already does some work.

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

Purpose5/5

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

The description clearly states the action: 'Send a verification code via Twilio Verify' and lists the supported channels (SMS, call, email, WhatsApp). This distinguishes it from sibling tools like twilio_check_verify (which checks codes) and twilio_send_sms (which sends plain SMS).

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

Usage Guidelines3/5

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

The description mentions the use of Twilio Verify but provides no guidance on when to use this tool versus alternatives (e.g., twilio_check_verify). It implicitly indicates usage for sending codes but lacks explicit when/when-not statements.

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