verify_email_otp

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

Describes key outcomes (activate account, start session) beyond annotations which indicate idempotency and non-destructiveness. However, it lacks details on side effects or error handling for invalid/expired tokens.

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

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

Two sentences, front-loaded with the core purpose, no fluff. Each sentence contributes essential information.

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

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

Covers purpose and outcome for a simple two-parameter tool without output schema. However, missing details on error states (e.g., expired token) or response format.

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

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

Schema describes 'token' format (6-digit or link) but not 'email'. With 50% schema coverage, the description adds no additional parameter meaning beyond what the schema provides.

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

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

Clearly states the tool verifies an email OTP token and activates the account while starting a session. It is specific about the resource (AlgoChains confirmation email) and distinguishes from siblings like verify_code or verify_mfa.

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

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

Implies usage for initial account activation via confirmation email, but does not explicitly state when to avoid using it (e.g., if already verified) or mention alternatives like verify_code for other OTP scenarios.

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