powerwall_logout

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

No annotations exist, so the description must disclose behavior. It clearly states that the tool 'expire[s] the current authentication token', which is the core side effect. It doesn't cover failure modes or reversibility, but for a logout action this is reasonably transparent.

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, terse phrase that fully conveys the action. It contains no filler, is front-loaded with the verb, and is appropriately sized for a tool with no parameters.

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 logout tool with no parameters and no output schema, the description covers the essential effect. It could mention whether authentication is required or how it handles an already-expired token, but such details are arguably secondary and not critical for correct invocation.

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 takes zero parameters and the input schema is empty, so the description has no parameter semantics to add. Per the baseline for 0 params, a score of 4 is appropriate; no compensation is needed.

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 'Logout' and names the resource 'authentication token', clearly stating what the tool does. It is distinct from siblings like powerwall_login and the various get/set tools, leaving no ambiguity about its function.

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 purpose implies usage after a session is established, but there is no explicit mention of when to use it versus alternatives, nor any conditions or prerequisites. The contrast with powerwall_login is implicit but not stated.

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