Save Project Copy

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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false and openWorldHint=false, so the write nature is covered structurally. The description adds only boilerplate ('returns verifiable structured results', 'write and path restrictions per service capabilities') without saying what happens to an existing file at the output path, whether overwrite is permitted, or what the copy preserves.

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, with no wasted clauses, but the brevity comes from generic filler rather than useful information, so it is only adequate.

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?

The presence of an output schema excuses explaining return values, but for a two-path mutation tool with 0% parameter coverage the definition omits the essential detail: where the copy is written and under what constraints. What remains is insufficient for an agent to invoke it confidently.

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% for two required parameters (aprx_path, output_aprx_path), so the description must compensate and does not. It never clarifies that one path is the source project and the other is the destination copy, nor any format or overwrite rules for the output path.

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 'ArcGIS Pro: save project', which restates the sibling arcgis_pro_save_project rather than the actual 'save a copy to a new path' semantics implied by the name and by the required output_aprx_path parameter. An agent cannot tell this apart from save_project without opening the schema.

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 statement of when to use this tool versus arcgis_pro_save_project or the other save/export siblings. The only hint is a generic note that write and path restrictions follow service capabilities, which does not route the agent to a choice.

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