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

With no annotations, the description carries the full burden of behavioral disclosure. It does disclose the authorization requirement and the specific fields returned, which is useful. However, it does not explicitly state that this is a read-only operation or describe error/edge-case behavior, though that is reasonably implied by 'status' and the listed data.

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 very compact and front-loads the key returned fields before the auth requirement. Every phrase carries information. It loses a point for being a fragment rather than a complete, self-contained sentence, but there is no waste.

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 status tool with no output schema, the description provides the essential return fields and the auth requirement, which is sufficient for a basic call. It does not explain response formatting or possible failure states, but the low complexity keeps this from being a major gap.

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 is nothing for the description to elaborate beyond the schema. Per the baseline for 0-parameter tools, a score of 4 is appropriate since no parameter clarification 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 names the specific resource (current agent plan) and enumerates the returned fields, so the tool's purpose is clear. It lacks an explicit verb such as "get" or "retrieve," and it does not explicitly distinguish itself from sibling tools, though its resource is distinct.

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 guidance is given about when to use this tool versus alternatives. The only operational note is the Bearer authorization requirement, which is not usage guidance. Sibling tools are not mentioned or contrasted.

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