trybiut_status

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

With no annotations provided, the description carries the full behavioral burden. It discloses the key authenticational trait ('No login needed') and implies a read-only reachability probe. It does not detail response shape or failure semantics, but for a parameterless health check this is reasonable.

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 short sentences with no wasted words. The primary purpose is front-loaded, and the only additional trait worth stating, the lack of a login requirement, is included succinctly.

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 tool with no parameters, no output schema, and a very simple purpose, the description provides enough information to select and invoke it correctly. Nothing essential is missing; an agent can confidently use this as a pre-flight connectivity check.

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 and schema description coverage is 100%, so the schema fully defines the input surface. The baseline for a 0-parameter tool is 4, and the description does not need to add parameter-level detail.

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 ('Check') and a clear target resource ('trybiut.com API reachable'). This distinguishes it from the tax, auth, invoice, and pricing siblings, which all perform different domain 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?

It clearly communicates that no login is required, which is a useful usage prerequisite and implies this is a pre-flight connectivity check. It does not explicitly name alternatives or state when not to use it, but for a status probe the context is clear.

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