get_session_status

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

The readOnlyHint annotation already establishes that this is a non-destructive read, and the description's 'get' is consistent with that. The description adds no further behavioral context such as return format, error cases, or authentication requirements, but the simple read-only nature keeps this from being a major gap.

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 five-word sentence that front-loads the exact action. There is no filler, repetition, or unnecessary detail.

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?

With zero parameters, a read-only annotation, and a self-explanatory status getter, the description is mostly adequate for calling the tool. The lack of an output schema leaves the return structure unspecified, but the minimal surface area reduces the impact of that omission.

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 there are no parameter semantics for the description to explain. The baseline of 4 applies because the input schema is empty and the description does not need to compensate for any parameter documentation.

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 ('get') and resource ('current session state'), clearly indicating a read operation. It is distinguishable from the sibling tool 'clear_session' as the inverse action, though it does not explicitly name or contrast that sibling.

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 usage context is implied: call this when you need to know the current session state. However, it provides no explicit when-to-use or when-not-to-use guidance, nor does it compare itself with any alternative tools.

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