Gp Merge

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, covering the safety profile. The description adds only a vague claim of 'verifiable structured results' and that write/path limits depend on service capability, which is marginally useful but adds little concrete behavior (e.g., whether the output is overwritten, spatial-reference handling).

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 short and front-loaded, but the brevity comes from under-specification rather than efficiency; the sentences convey almost no actionable information and partly duplicate the title.

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 need not be explained, but for a two-parameter write tool with 0% schema coverage, no annotations-only safety gaps filled, and no differentiation from sibling geoprocessing tools, the description is too thin to support correct invocation.

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 the description says nothing about in_feature_paths or output_feature_class. With two undocumented parameters, the description fails to compensate for the schema gap entirely.

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 ('mergegp merge') without stating what merging entails or what resource is merged. It never distinguishes this from the many sibling overlay/combination tools (gp_append, gp_union, gp_intersect, gp_dissolve). An agent gets the verb but no real elaboration of purpose.

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 guidance on when to use merge versus alternatives such as append, union, or intersect, and no prerequisites or context conditions are given. The brief note about 'write and path restrictions per service capability' is a caveat, not usage guidance.

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