Project Cache Status

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds useful non-obvious behavior: it reads from the file-mode ArcGISProject cache and CURRENT projects are not cached across requests. It still does not describe the exact cache states or failure modes beyond that caveat.

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?

The description is two compact clauses separated by a semicolon, with the core purpose and the key caching caveat front-loaded. Every clause carries information and there is no filler.

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 tool is a simple parameterless status read, an output schema exists, and annotations cover the safety profile, so the description need not explain return values. It provides the essential cache-scope context, though it could better connect this tool to related project lifecycle tools.

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?

The tool has zero parameters, so there are no parameter semantics to explain. Per the scoring rubric, zero parameters establish a baseline of 4 when no additional parameter information is needed.

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 specific verb and resource: reading the project path from the file-mode ArcGISProject cache. It also clarifies that CURRENT projects are not cached across requests, which helps distinguish its scope. It does not explicitly name sibling tools or contrast itself with project release/reload operations.

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?

The description gives no explicit guidance on when to call this tool versus alternatives such as arcgis_pro_release_project or arcgis_pro_reload_project. The note about CURRENT projects not being cached is behavioral context, not usage guidance, and no when-to-use or when-not-to-use conditions are stated.

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