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

No annotations are provided, so the description carries the full burden. "Get" implies a safe read, but the description says nothing about authentication requirements, whether the response is text or a version identifier, or any rate limits. It discloses the returned subject matter, which is some help, but falls short of what an unannotated tool ideally provides.

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?

Two short fragments with no filler; the resource is front-loaded and nothing is repeated from the schema.

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 trivial zero-parameter read with no annotations and no output schema, the description covers the resource but not the response shape (URL, text, version string) or any access prerequisites. It is minimally sufficient rather than complete.

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, which is the baseline-4 case. There is no parameter semantics to add, and the description correctly implies no inputs are 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?

States a specific verb ("Get") and resource ("Othrum Terms of Service and the current version"), so the agent knows this is a read of ToS content plus its version. It does not differentiate itself from the sibling tool 'onboarding', leaving the boundary between the two implicit.

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?

"Optional reference." hints that the tool is not mandatory but gives no condition for when to call it, no when-not guidance, and never mentions the 'onboarding' sibling as an alternative. The agent has to infer usage entirely.

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