get_important_urls

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

Annotations declare readOnlyHint=true, so the agent knows this is a safe read operation. The description adds context about the data returned (monitored important URLs and their status history) but does not disclose return format, pagination, or other behaviors. With annotation coverage, this is acceptable but not rich.

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?

The description is a single sentence with no unnecessary words, making it concise and front-loaded. However, it lacks an explicit action verb, which slightly reduces clarity despite its efficiency.

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 simple read-only tool with two well-documented parameters, the description provides a basic understanding of purpose but leaves gaps such as what constitutes 'important URLs' and the exact structure of status history. Given schema details and annotations, it is adequate but not comprehensive.

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%, with both host_id and format fully described in the schema. The tool description adds no parameter-specific information, so it relies on the schema for semantics.

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 clearly indicates the tool returns data about monitored important URLs and their status history for a host. Although it lacks an explicit verb like 'get' or 'list', the noun phrase conveys the resource and scope, and it distinguishes from sibling tools by focusing on 'important URLs' and 'status history'.

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?

No usage guidance is provided. The description does not state when to use this tool versus alternatives like get_sitemaps or get_indexing, nor does it mention prerequisites (e.g., that host_id should come from get_hosts). This is entirely absent.

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