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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so safety is covered structurally. The description usefully signals the content shape (what each industry does, whether it has a dedicated page) but says nothing about ordering, volume, or return format.

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?

A single dense sentence with no filler, and the core content claim leads. The phrasing around 'the page for the ones with their own page' is slightly convoluted but not wasteful.

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 output schema and no parameters, the description carries the burden of explaining what comes back and it only loosely does so ('what it does for each, and the page for the ones with their own page'). It is enough to attempt the call but leaves the response shape underspecified for a discovery tool whose whole purpose is the returned content.

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 baseline is 4; the description correctly implies a no-argument listing call. Nothing it could add about parameters would be meaningful here.

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 noun phrase 'The kinds of business Larkella answers calls for' does convey that the payload is a catalogue of supported industries with per-industry descriptions, but it never uses a verb to state that the tool returns that list. It also gestures at a sibling relationship ('the ones with their own page') without naming the `industry` tool that fetches a single one.

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 explicit when-to-use or when-not guidance; an agent must infer that this is the browse/discovery entry point and that `industry` is for drilling into one entry. The phrase 'the page for the ones with their own page' points at that split only obliquely.

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