mmar_logout

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

With no annotations provided, the description carries the full burden. It discloses the key behavioral detail of clearing the stored session token, which is the core side effect. It does not mention edge cases like idempotency or failure when not logged in, but for a simple logout operation, this is adequate.

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?

The description is a single, front-loaded sentence that states the action, target, and mechanism. Every word contributes to clarity, with no unnecessary detail or repetition.

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?

The tool is trivial: no parameters, no output schema, no annotations. The description fully explains the tool's purpose and behavior, leaving no significant gaps. Additional details about return values or error handling are not necessary given the simplicity.

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?

The tool has zero parameters, so the baseline is 4 per the rubric. The description adds no parameter details, but none are needed. The schema is empty, and the description clearly explains what the tool does without requiring parameter explanations.

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 states 'Log out from the MM-AR platform' with a specific verb and resource, and explains the mechanism 'by clearing the stored session token.' This distinguishes it from siblings like mmar_login and mmar_check_session.

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 the usage context: it is for ending a session on the platform. It does not explicitly mention alternatives or exclusions, but the purpose is unambiguous, making it clear when to use this tool.

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