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

Annotations cover the safety profile (readOnlyHint, idempotentHint, openWorldHint=false), but the description adds the one thing annotations cannot: that the result is a boolean accompanied by the nearest served town, useful context given no output schema exists. It stops short of describing boundary behavior (e.g. ZIPs partially covered or unknown ZIPs).

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 sentences, zero filler, with the core question front-loaded and the return contract immediately after. Every clause earns its place.

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 one-parameter read-only predicate with no output schema, the description adequately covers intent and return shape. It is only slightly thin on how the answer should drive subsequent calls relative to the sibling tools.

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?

Schema description coverage is 0%, so the description must carry the meaning of the single parameter. It identifies it as a 'US ZIP code', which adds domain scope, but the 5-digit format is already enforced by the schema pattern and no invalid-input or alternate-format behavior is described.

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 precise predicate ('Is a US ZIP code inside the Tulsa service area?') and the exact return shape (yes/no plus nearest served town). The check-style scope clearly separates it from get_service_info and request_service without needing to open either schema.

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?

Usage is implied by the question form — it reads as a pre-flight eligibility check — but the description never says when to call this versus get_service_info or request_service, nor any prerequisite or exclusion condition. Adequate but leaves routing to inference.

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