Get Available Naics

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds nothing beyond that — no statement about caching, stability, or how results are returned — so it contributes no behavioral context of its own.

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 words with no structure is under-specification rather than conciseness. There is nothing to front-load because nothing is stated, so brevity here costs the agent information rather than saving it.

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?

A zero-parameter read tool with no output schema is simple, but the description still leaves open what a NAICS list contains and in what form. For a reference-data lookup, one sentence on the returned code set would have closed the 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 takes zero parameters, which is the baseline-4 case; there is nothing for the description to disambiguate. The empty schema is self-explanatory on its own.

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?

"NAICS list" only restates the title "Get Available Naics" and adds no verb, scope, or resource detail. An agent learns nothing about what NAICS codes are returned or whether they are global reference data versus instance-specific.

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?

There is no when-to-use guidance and no mention of alternatives. The sibling tools GetV1AvailableRails and GetV1AvailableBankDetails occupy the same 'available reference data' family, and the description does nothing to distinguish this lookup from them.

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