xae_status

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

readOnlyHint=true and destructiveHint=false already establish that this is a safe read. The description then only enumerates return fields, which the existing output schema already carries, so it adds essentially no behavioral context beyond the annotations and structured output.

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 a single terse fragment with no wasted words, but it is only a comma-delimited list with no leading verb or framing, so it is under-structured rather than genuinely well-structured.

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, yet the description duplicates that field list while omitting any statement of what the tool is for or when to invoke it. Adequate but with clear gaps for a zero-parameter status tool in a dense sibling set.

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 takes zero parameters, so there is nothing for the description to disambiguate. The baseline of 4 applies; the schema fully covers the (empty) input surface.

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 is a bare field list ('Shell version, open solution, projects, TwinCAT project name, target NetId, started flag') rather than a stated purpose. An agent can infer this returns status about the TwinCAT XAE shell, but there is no verb and no explicit scope statement, and no differentiation from the sibling xae_diagnostics.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as xae_diagnostics or ads_status, which also surface status information. The agent is left to infer when this tool is the right choice.

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