dropSession

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

There are no annotations, so the description carries the full responsibility for behavioral disclosure. It states the tool clears the local session cache, which implies a client-side operation, but it does not explain side effects, whether it affects authentication, or whether it is safe to invoke at any time.

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: 'Clear local session cache'. It contains no filler, and every word adds meaning, achieving maximum conciseness.

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 simple, parameterless operation, the description sufficiently states the action and scope ('local cache'). It is almost complete, though it could explicitly mention that it does not log the user out or affect server state. However, given the simplicity, it is largely adequate.

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 description does not need to add parameter details. Per the rubric, a zero-parameter tool receives a baseline of 4, and the empty schema is self-explanatory.

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 uses a specific verb ('Clear') and a specific resource ('local session cache'), clearly indicating what the tool does. The word 'local' distinguishes it from session-related siblings like logout, which likely affect the server-side 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?

No usage guidance is provided. The description does not state when to use this tool, what prerequisites exist, or how it relates to alternatives such as logout. It is a bare statement of function without context.

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