Verify AIS Login OTP

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

Annotations (readOnlyHint=false, openWorldHint=true, idempotentHint=false) already indicate mutation and side effects. Description adds value by specifying 'establish an in-memory AIS session,' but does not detail error cases or required prerequisites.

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?

Single sentence with 14 words, front-loaded with purpose and key detail. No superfluous content.

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 verification tool with 2 parameters and no output schema, the description covers core purpose, parameter detail, and outcome. It could mention error handling or success/failure indication.

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?

Description explains the 'otp' parameter (5-digit OTP from IITR email/SMS), matching the pattern. However, the 'username' parameter is not mentioned, and schema coverage is 0%, so description only partially compensates.

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?

The description clearly specifies the action (verify OTP) and resource (5-digit IITR email/SMS OTP) and outcome (establish in-memory session). It distinguishes from siblings like ais_auth_send_sms_otp (sends OTP) and ais_auth_login (initiates login).

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?

The description implies usage after receiving an OTP ('Verify the 5-digit IITR email/SMS OTP'). It provides clear context but lacks explicit when-not-to-use or alternative references.

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