jio_logout

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states that the tool clears the 'local saved session,' indicating the primary effect and specifying that it is limited to local data. However, it does not discuss reversibility, side effects, or whether the server session is also invalidated, leaving some ambiguity about the full impact.

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, concise sentence that is front-loaded with the action ('Clear'). It contains no wasted words and is appropriately brief for a tool with no parameters and a straightforward function.

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 zero-parameter logout tool, the description is largely complete, clearly stating the action and the scope (local session). However, it does not clarify whether this is a full logout (including server-side invalidation) or what the return value indicates. Given the simplicity and lack of output schema, the description is minimally sufficient but leaves a couple of minor gaps.

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 input schema has zero parameters, so schema description coverage is 100% by default. Since there are no parameters to explain, the baseline for parameter semantics is 4. The description does not need to add parameter details, and it doesn't, which is appropriate.

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 'Clear the local saved session.' uses a specific verb ('clear') and identifies the resource ('local saved session'), which clearly indicates a logout action. This distinguishes it from sibling tools like jio_login and jio_auth_status, as it uniquely deals with terminating the 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 does not explicitly state when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. However, the name 'logout' and the action 'clear session' imply that it should be used when ending a user's session. This is a case of implied usage, aligning with a score of 3.

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