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

With no annotations available, the description carries the full burden. It discloses the tool's read-style behavior by framing it as testing the connection and reading status, and it enumerates the returned state. It does not explicitly state that no project modifications occur, but the 'status' and 'current state' language strongly implies a non-mutating operation.

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 sentences, front-loads the core purpose, and adds a useful usage directive. Every sentence earns its place with no redundancy or 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?

For a zero-parameter status/health-check tool with an output schema, the description is complete: it names the connection action, enumerates the status content, and instructs the agent to call it first. No additional input, prerequisite, or behavioral detail is essential 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?

The tool accepts zero parameters, and the schema confirms this with an empty properties object. The baseline for a zero-parameter tool is 4, and the description appropriately adds no parameter details since none are 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 clearly states the tool's purpose: 'Test the connection to ArcGIS Pro and get the full project status', with a specific verb and resource. It lists the items returned, but it does not explicitly distinguish itself from the sibling get_project_info, which likely overlaps in project-status reporting.

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 clear usage context: 'Always call this first to understand the current state before running any other operations.' This directly tells the agent when to use the tool, though it does not mention alternatives or when not to use it.

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