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

No annotations are provided, so the description must carry the full behavioral disclosure burden. It mentions 'Routing origin history (RIPE Stat)' which implies a read-only data retrieval, but it does not describe the output format, any constraints, or side effects. The description is too brief to convey expected behavior.

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 short sentence, which is concise, but it is under-specified rather than appropriately concise. It front-loads the title-like phrase but omits essential details. For a tool with one parameter, the brevity is not effective.

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?

The tool has one parameter, no annotations, and an output schema (content unknown). The description gives only a high-level topic without explaining how to invoke the tool, what input to provide, or what to expect in return. It is incomplete for an agent to correctly call it.

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 schema has one parameter 'q' with default '' and no description, and schema description coverage is 0%. The description does not explain what 'q' represents (e.g., ASN, IP, prefix), leaving the parameter entirely ambiguous. With no coverage, the description must compensate but fails to do so.

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 provides BGP routing origin history sourced from RIPE Stat, which distinguishes it from many network-focused siblings. However, it does not explicitly state the action (e.g., 'query' or 'fetch'), and it is phrased as a noun phrase rather than a verb+resource. It is more specific than a tautology but lacks an explicit action.

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 to use this tool versus any of the many sibling tools, nor any mention of conditions, prerequisites, or alternatives. The description provides zero context for selection.

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