Gp Aggregate Polygons

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, so the safety profile is largely covered by structured data. The description adds only vague phrasing about 'write and path restrictions depend on service capabilities', which is not actionable detail about permissions, output overwrite behavior, or aggregation semantics.

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 text is short but consists of a redundant name restatement plus generic filler about structured results and service capabilities. Nothing is front-loaded or informative; the brevity reflects under-specification rather than conciseness.

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 geoprocessing tool with three mandatory, undocumented parameters and no usage guidance, the description is wholly inadequate. An output schema exists so return values needn't be explained, but everything else an agent needs to invoke this tool correctly is absent.

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?

Schema description coverage is 0% and all three required parameters (in_features, out_feature_class, aggregation_distance) are undocumented in both schema and description. The description provides zero compensating information about formats, units for aggregation_distance, or expected dataset types.

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 essentially restates the tool name ('aggregate polygons') with a language-mixed prefix and adds no verb+resource specificity beyond what the name already conveys. It does not distinguish this tool from the many other gp_* siblings (dissolve, merge, union). This is close to tautology.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as gp_dissolve or gp_merge. The only contextual sentence is generic boilerplate about service capability limits, which does not help an agent decide when to call this tool.

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