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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description goes beyond that by disclosing the content inventory of the returned policy set, including what is explicitly not offered, which is the kind of context annotations cannot carry.

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?

Front-loaded with the resource and its contents, and every listed item is a distinct topic an agent may need to answer a customer question. It is a single long run-on sentence, and "in one call" is mild filler, but there is no wasted substance.

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 no parameters and no output schema, the description carries the burden of telling the agent what comes back, and it does so by enumerating the policy areas. Nothing critical is missing for an agent deciding whether to call it; only the response format/length is unstated, which is minor.

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?

Zero parameters, so there is nothing to document and the baseline of 4 applies. The description correctly avoids describing any inputs, reinforcing that this is a no-argument lookup.

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 a specific resource domain (Hark Tech repair policies) and enumerates exactly what the single call returns: mail-in process, assessment fees, excluded services, turnaround, warranty, postage, trade rates, payment and privacy. That is far more than a restatement of the name. It does not, however, distinguish itself from the sibling get_service_info, which an agent might reasonably reach for instead.

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?

"Use it to answer process questions accurately" gives broad context but no explicit when-not and no named alternative against get_service_info or get_repair_status. It also implicitly signals scope limits (no phones/tablets, no BGA work), which is mild negative guidance, but the agent is left to infer the boundary itself.

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