backend_status

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

With no annotations, the description carries the full behavioral burden; it does at least establish that this is a read operation, which is the key safety signal. Beyond that it discloses nothing about cost, permissions, or freshness of the configuration data, so the disclosure is minimal rather than rich.

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?

A single front-loaded sentence with the positive statement first and the disambiguation second; nothing is wasted. The trailing clause about CAD execution is slightly cryptic in isolation but earns its place as the main misuse guard.

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 trivial (no inputs, output schema present, so return values need not be explained), which lowers the bar considerably. However, "backend configuration" remains vague about what configuration domain is returned, leaving the agent unable to judge relevance before calling.

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 no parameter semantics to explain and the baseline of 4 applies. Nothing in the description contradicts or obscures the empty schema.

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 gives a specific verb and resource ("Read backend configuration") and explicitly negates the most likely misreading of the name backend_status, namely that it is a health check. It does not name or contrast with any sibling tool, but the sibling set (cabinet/design/material/CAD tools) contains no close analogue, so differentiation is less critical here.

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 one useful exclusion ("not a health check of CAD execution"), which prevents a plausible misuse, but no positive statement of when an agent should call this rather than another tool. Usage is only implied by the negation rather than stated.

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