Add Feature Class To Topology

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds no behavioral context beyond that — nothing about side effects on existing topology rules, whether ranks must be unique, or whether the change is persisted immediately.

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?

A single front-loaded sentence with no filler, which is structurally clean. However, for a four-parameter mutation tool the brevity reflects under-specification rather than earned 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?

An output schema exists, so return values need not be described. But for a non-idempotent, non-read-only topology mutation, the description supplies no prerequisites, no post-conditions, and no parameter semantics — a significant gap given the 0% schema coverage.

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%, so the description carries the full burden for four parameters. It only gestures at xy_rank/z_rank ('设置 XY/Z rank') and ignores topology_path and feature_class entirely, adding almost no meaning beyond the schema titles. The rank semantics (what higher/lower rank means for coincident geometry) are left unexplained.

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 concrete verb+resource ('把要素类加入拓扑' — add a feature class to a topology) and names the tunable ranks, so an agent knows exactly what operation this performs. It does not distinguish itself from close siblings such as arcgis_pro_add_rule_to_topology or arcgis_pro_remove_feature_class_from_topology, so it stays below a 5.

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 this versus creating a topology, adding rules, or removing a feature class. It also omits prerequisites such as whether the topology must already exist or whether an edit/save is required afterward. The only usage information is implied by the verb itself.

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