hosts_content

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

With no annotations at all, the description carries the full burden of disclosure, and it does not meet that burden. It never states that the operation is read-only, how deep the traversal goes, whether all sections are returned or only a subset, whether a missing host errors or returns empty, or anything about response shape.

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?

It is a single short sentence with no filler, which is good, but its brevity comes at the cost of under-specification rather than efficiency. Nothing is front-loaded beyond a restatement of the tool name, and the parenthetical adds no actionable information.

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?

There is no output schema and no annotations, so the description must explain what 'sections and items' actually look like, how the two relate, and how large a response can be. None of that is present, leaving an agent unable to predict the result or choose this tool confidently over its several close siblings.

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 100% and the host parameter already documents itself with short-name examples (career / its / officialweb-test). The description only restates '某个子域' (a certain subdomain) and adds no new meaning such as accepted formats, case sensitivity, or behavior for unknown hosts, so the baseline of 3 applies.

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 phrase "取某个子域的栏目与条目" names a verb (fetch) and a resource (subdomain sections and items), so the basic purpose is inferrable. However, the qualifier "（通用挖掘）" (general mining) is vague and the description never distinguishes this tool from sibling tools such as site_content, site_detail, sites_index, or hosts_inventory, all of which operate on the same site/host space.

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 guidance on when this tool should be used instead of hosts_inventory, site_content, site_detail, or sites_index. No prerequisites, no exclusions, and no indication of what 'general mining' means relative to the more specific-looking sibling tools.

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