Rename Layer

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

Annotations already declare the important traits (readOnlyHint=false, idempotentHint=true, destructiveHint=false, openWorldHint=false), so the description's burden is lighter. Its added sentence ('写入和路径限制以服务能力为准' / write and path restrictions depend on service capabilities) is generic boilerplate that hints at permission- or capability-gated writes but names no concrete behavior, error mode, or side effect.

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 the purpose is front-loaded, which is good, but the second clause about 'verifiable structured results' and 'service capabilities' is filler that communicates little concrete information. Roughly half the text does not earn its place.

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 with four required, undocumented parameters and no annotations covering path/permission constraints, the definition is far too thin for a mutation tool. It should at minimum explain what aprx_path/map_name/layer_name identify and what failure (missing layer, duplicate name, locked project) looks like.

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 four parameters (aprx_path, map_name, layer_name, new_name) are undocumented in the schema. The description says nothing about any of them — not path format, not whether layer_name must be unique, not whether new_name must differ — leaving the agent with zero semantic guidance for a 4-required-parameter tool.

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 states a clear verb+resource pair ('重命名图层' / rename layer), which is specific enough to distinguish it from siblings like arcgis_pro_rename_map or arcgis_pro_rename_layout by the target resource. However, it offers no explicit sibling differentiation or scoping detail (e.g. that it operates on a layer inside an .aprx map).

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 (e.g. project must be open), and no mention of alternatives such as arcgis_pro_rename_map, arcgis_pro_rename_layout, or arcgis_pro_gp_rename_dataset. The agent must infer applicability purely from the tool name.

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