sibs_test

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

With no annotations, the description carries the full behavioral burden. It accurately discloses that the tool verifies token/credentials validity, implying a read-only, non-mutating operation. It does not describe failure behavior or return format, but for a simple auth test this is a minor gap.

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?

Two concise sentences, front-loaded with the key purpose. Every word adds value and there is no redundant or filler content.

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 low-complexity with no inputs, so the description covers the essential call context. The only slight gap is not explicitly describing the return value or failure signaling, but 'verifies' strongly implies a boolean or success/failure result, making the definition adequately complete.

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 the description does not need to explain parameter meaning. The baseline for 0 params is 4, and there is no missing parameter information to penalize.

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 action (test) and a specific resource (SIBS API authentication), with the explicit outcome of verifying Bearer token and credentials. This clearly distinguishes it from the sibling payment-operation tools.

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?

Usage is implied rather than explicitly stated. The description indicates the tool is for testing authentication, but it does not mention when to prefer it over alternatives or any prerequisites. Since no sibling tool performs auth testing, the context is still fairly clear, but explicit guidance is missing.

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