TDQS

D1.3/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds only that results are verifiable/structured and that write/path limits depend on service capabilities; this is a relevant but vague caveat and omits overwrite behavior, output workspace requirements, and permissions. It does not contradict annotations.

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

Conciseness2/5

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

The description is short, but it is not front-loaded with the tool's purpose; the first clause is essentially 'ArcGIS Pro: raster raster,' which wastes space. The generic second sentence does not help selection or invocation.

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

Completeness1/5

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

For a geoprocessing tool that writes an output dataset and has three parameters, the description omits the core operation, parameter meanings, and usage context. Although an output schema exists, the description still leaves an agent unable to invoke the tool correctly.

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

Parameters1/5

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

Schema description coverage is 0%, and the description does not mention in_raster, out_polygon_features, or simplify. It provides no syntax, format, or meaning for any of the three parameters.

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

Purpose1/5

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

The description never states that this tool converts a raster to polygon features; it only names the platform and repeats 'raster,' then gives generic return/write caveats. The actual action is inferable only from the tool name/title, not from the description text.

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

Usage Guidelines1/5

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

There is no when-to-use guidance, no mention of alternatives such as polygon_to_raster or feature_to_raster, and no prerequisites. The generic write/path caveat does not help an agent decide when to select this tool.

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