Remove Join

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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=false, so the safety profile is covered structurally. The description adds only vague boilerplate ('returns verifiable structured results; write and path restrictions subject to service capabilities') and says nothing concrete about what gets removed, the required confirmation, or failure behavior.

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, but the length is achieved by omitting necessary content while including a generic filler sentence about service capabilities. Nothing is front-loaded except the tautological restatement of the name.

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 destructive, five-parameter mutation tool the description provides no prerequisites, no confirmation semantics, no path or project requirements, and no failure guidance. It is not sufficient for 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% across five required parameters, so the description carries the full burden — yet it mentions none of aprx_path, map_name, layer_name, join_name, or confirm_join_name. The paired join_name/confirm_join_name confirmation pattern, a clear safety mechanism, goes entirely 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 essentially restates the tool name and title ('remove join' / '移除remove join') without adding a specific scope, target object, or distinction from siblings such as arcgis_pro_add_join or arcgis_pro_remove_relate. It is a tautology of the name rather than a stated 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?

No when-to-use, when-not-to-use, prerequisite, or alternative is given. The second sentence discusses generic 'service capability' limits in a way that is unrelated to selecting this tool, leaving the agent with zero guidance on routing.

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