test_verify

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

With no annotations, the description carries the full disclosure burden. It discloses the test-only restriction, the bypass of real OTP, and the required environment setup. It could go further by stating side effects or irreversibility, but it gives substantial behavioral context beyond the schema.

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?

Compact and front-loaded. The key purpose and test-only scope appear in the first sentence; the access setup is separated and actionable. Every sentence earns its place.

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?

For a one-parameter test utility with no output schema, the description provides enough context: purpose, test-only constraint, OTP bypass, and access prerequisites. It does not describe the return value or side effects, but is otherwise sufficient for correct invocation.

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 coverage is 100% and the single parameter 'id' is already documented as 'Verification ID'. The description adds no extra param-level meaning, so the baseline of 3 applies.

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?

States a specific action ('Auto-complete a verification') on a specific resource, with a clear scope ('test mode', 'pk_test_* API keys only'). This differentiates it from production verification flows and sibling tools like submit_verification_code.

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?

Clearly says when it is useful: testing flows without real OTP delivery. Provides explicit access prerequisites and warns that start_login does not open this tool. However, it does not explicitly compare itself to closely related siblings like trigger_verification or submit_verification_code.

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