Update Layout Text Element

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, so the safety profile is covered structurally. The description only adds generic filler ("returns verifiable structured results; write and path restrictions per service capabilities") that conveys no concrete behavior, such as what happens to dynamic text or whether the .aprx is written to disk.

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 almost none of the brevity is spent on useful content: the first clause is a tautology and the second half is generic service-capability boilerplate. Front-loading is absent because there is no substantive payload to front-load.

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?

For a 6-parameter write tool with an output schema, zero parameter documentation, and no behavioral detail, the description is far too thin. An agent would have to guess the .aprx path format, when element_type matters, and whether overwriting dynamic text is safe.

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 6 parameters, and the description supplies no parameter meaning at all. Critically, allow_dynamic_text_overwrite (default false) and element_type are left completely unexplained, so an agent cannot tell which fields are required semantics versus optional overrides.

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 says only "更新布局" (update layout), which restates a coarser version of the name and never mentions the text-element resource that distinguishes this tool from arcgis_pro_set_layout_element_position, arcgis_pro_layout_upsert_element, or arcgis_pro_layout_element_info. It is effectively a tautology plus boilerplate, and it misdirects by naming the layout rather than the text element.

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 indication of when to use this versus sibling layout-mutation tools, no prerequisites, and no mention of the alternative arcgis_pro_layout_upsert_element which appears to overlap heavily. Nothing is stated about the aprx being loaded or the element needing to exist.

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