About the Hosannaith reliability oracle

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

With no annotations, the description carries the full burden, and it delivers useful context: the call is free (a cost disclosure) and it is purely informational ('Explains'), strongly implying no side effects. It stops short of explicitly stating there are no mutations or describing the shape of what is returned.

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?

Three short sentences, front-loaded with the cost qualifier ('Free.'), then purpose, then the usage rule. Every clause earns its place with no redundancy.

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-param, read-only documentation tool with no output schema, the description covers what it explains, when to call it, and that it is free. It could say slightly more about what the returned guidance looks like, but it is close to 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 takes zero parameters, so the baseline is 4. There is nothing schema-wise to document, and the description correctly focuses on the tool's role rather than fabricating parameter guidance.

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 (Explains) and resource (what the Hosannaith x402 reliability oracle returns and how to act on a score), and it is clearly differentiated from the sibling check_x402_reliability tools, which perform the actual checks.

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 gives an explicit ordering rule — 'Call this once before check_x402_reliability so you can interpret the result' — naming the exact sibling and the condition that selects this tool. Nothing is left to inference.

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