Gp Statistics

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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false. The description adds only a vague note that write/path restrictions follow service capability, plus a generic claim of 'verifiable structured results' — no detail on what gets overwritten in out_table, permissions, or failure behavior beyond what annotations imply.

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?

Very short, but the content is boilerplate fragments in mixed Chinese/English rather than a front-loaded purpose statement. Brevity here reflects under-specification, not efficient communication.

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-value explanation is not required, and annotations cover the safety profile. However, for a 3-required-parameter geoprocessing tool with zero schema descriptions, the definition leaves the agent unable to determine input formats or how this differs from sibling statistics/aggregation tools.

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% across four parameters (in_table, out_table, case_field, statistics_fields), and the description explains none of them — not the expected string syntax for statistics_fields, nor how case_field groups results. The description completely fails to compensate for the schema gap.

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 title ('statistics / gp statistics') without stating a specific verb+resource outcome such as 'computes summary statistics on fields of a table and writes the result to a new table.' Given ~190 siblings including arcgis_pro_gp_frequency, arcgis_pro_gp_table_select and arcgis_pro_gp_summary-style tools, an agent gets no basis to distinguish this tool from them.

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?

No when-to-use, when-not-to-use, or alternative tool is named. The only pseudo-guidance ('write and path restrictions depend on service capabilities') is a generic disclaimer, not a selection criterion.

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