atlas_dpi_distribution

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

No annotations are provided, so the description carries the full burden. It mentions the data source ('Built from the DPI fingerprint library') but does not disclose behavioral traits such as data freshness, aggregation method, or limitations like coverage gaps.

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 two sentences, front-loaded with the core purpose. No extraneous words; every sentence adds meaningful context.

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 zero-parameter tool, the description is largely complete. However, it does not describe the output format or any example values, which could be helpful for an agent interpreting the result.

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 has no parameters (0 params, baseline 4). The schema coverage is 100% (empty schema), so the description does not need to add parameter details. It correctly implies no user input is needed.

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 states the tool provides a per-country breakdown of detected DPI vendors, using a specific verb ('breakdown') and resource ('DPI vendors'). It distinguishes from sibling tools like atlas_dpi_fingerprints, which likely deals with fingerprints rather than distribution.

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?

The description implies the tool is for exploring DPI vendor distribution by country, but it does not explicitly state when to use this tool versus alternatives like atlas_dpi_fingerprints or other atlas tools. No guidance on prerequisites or exclusions is provided.

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