jan3_login

Initiates the default free JAN3 login by emailing a 6-digit OTP to the user's address; verify the code to complete authentication.

Instructions

Default JAN3 login (free, email-OTP): the backend emails a 6-digit OTP to the user's address. Prefer this over the paid captchaless fallback (jan3_login_start). Follow up with jan3_verify.

TDQS

A4.2/5.0
Behavior3/5

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

Describes key behavior (sends OTP email) and free nature, but lacks details on side effects, rate limits, or idempotency. With no annotations, more depth would help.

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?

Two concise sentences, front-loaded with essential information, no unnecessary words.

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

Completeness4/5

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

Sufficient for a simple login tool with two parameters; covers purpose, workflow, and alternative. Could mention return values or async behavior but not critical.

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 has 100% coverage with descriptions for both parameters; description adds no extra parameter-level meaning beyond what schema provides.

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?

Clearly states it's for login via email-OTP, distinguishes from sibling jan3_login_start, and specifies the mechanism (emails 6-digit OTP).

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

Usage Guidelines5/5

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

Explicitly says to prefer over jan3_login_start and directs to follow up with jan3_verify, providing clear usage context.

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