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

No annotations are provided, so the description carries the full disclosure burden. Naming the free Mylnikov DB hints at coarse/approximate results and possible coverage limits, but nothing is said about input formats, rate limits, or how reliable the returned location is. For a lookup with zero annotation coverage this is thin.

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 compact line with the key mapping front-loaded, so nothing is wasted. However, the extreme terseness leaves real gaps rather than being economical.

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?

An output schema exists, so return values needn't be explained, but for a lookup tool with no annotations and no parameter documentation the description should supply input format and accuracy expectations. It leaves the agent guessing about what to pass in 'q'.

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 single 'q' parameter has 0% schema description coverage and no type/default meaning explained. The description's 'BSSID/cell' phrasing weakly signals the accepted input, but does not clarify whether both a BSSID and a cell ID are accepted, how to format them, or whether one is required (required=0).

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 names a specific resource (WiFi BSSID/cell) and outcome (approximate location), and the 'Mylnikov free DB' tag distinguishes it from the many other geo/IP lookups in the sibling list. It is clear what the tool does, though it never explicitly contrasts itself with siblings like ipgeo or geocode.

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 statement of when to use this versus alternatives, no prerequisites, and no exclusions. The agent must infer that this is the choice for wireless identifiers rather than IP addresses or coordinates.

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