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

No annotations exist, so the description carries the full burden. It does add real behavioral context by disclosing that the call uses the caller's OpenAny gateway credentials and that charges and authorization are decided by the gateway, which signals a potentially metered call. It stops short of describing the shape of the response (e.g. whether entries carry codes, hierarchy, or just names), leaving the read behavior under-explained.

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 with no filler, and the core purpose is front-loaded. The only structural weakness is that the two sentences are not properly separated in the source text and the second is generic gateway boilerplate rather than tool-specific detail.

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 lookup with no output schema, the description is adequate but thin: it never says what a returned industry record contains (name, NAICS code, identifiers) even though the title advertises NAICS codes, and it gives no hint about list size or whether the full taxonomy is returned in one call.

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, so the schema has nothing to disambiguate and the baseline of 4 applies. The description correctly implies no input is needed by framing the call as obtaining 'a list of all' industries.

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 states a specific verb and resource: obtain a list of all company industries. That distinguishes it reasonably well from siblings such as companies_autocomplete, keywords_autocomplete, or technologies_autocomplete, though it never mentions the NAICS codes that the title claims the taxonomy contains, so the agent learns less than the title implies.

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, no statement of preconditions, and no mention of alternatives such as the geo or keyword autocomplete/list tools that an agent might otherwise reach for. The agent must infer from the name alone that this is a reference-taxonomy lookup rather than a company search.

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