A3.5/5.0

Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'styled map' and gives no details on output format, persistence, side effects, or return behavior. The schema notes server-side geocoding, but the description adds little behavioral context beyond the basic purpose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One purposeful sentence plus a concrete example, with no filler. The key constraint ('centered on a single place') is front-loaded before the example.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple, with two fully documented parameters and a good example, so the basics are covered. However, with no output schema, the description should clarify what a successful call returns or how the map is delivered, and that is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema documents both parameters at 100% coverage, including the optional display name and server-side geocoding. The description's example showing place='Tokyo Station' is useful, but it does not add meaningful parameter semantics beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific action ('Generate') on a specific resource ('a styled map') with a clear scoping constraint ('centered on a single place'). This distinguishes it from sibling tools like generate_markers_map and generate_route_map, which imply multi-point or route maps.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'centered on a single place' and the example imply when to use this tool, but there is no explicit guidance about when to prefer a sibling tool. The routing to alternatives is left to inference rather than stated.

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