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

With no annotations, the description carries the full behavioral burden. It usefully discloses what the response reveals (liveness plus configured backends), which is an information-disclosure trait, but says nothing about auth requirements, cost, or that it is a side-effect-free read. Adequate but not 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 no filler. The core purpose and the payload contents are delivered immediately.

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?

There is no output schema, so the description must describe returns, and it does name the two main return components (liveness and configured backends). For a zero-parameter health endpoint this is nearly complete, though it omits response format details an agent might want.

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 to document and no schema semantics to add. Baseline 4 applies; no parameter-related gap exists.

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?

Names the resource (this server's service) and states exactly what is returned: liveness status plus which privacy-chain backends (Monero, Zcash) are configured. That is far more specific than a bare 'health check', and no sibling tool overlaps this function. It stops short of a 5 only because it does not need to, and does not, position itself against any sibling.

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?

The description gives no when-to-use guidance, no indication of whether authentication is required, and no mention of alternatives or rate limits. The usage (call to verify the server is up and see backend configuration) must be inferred entirely from the name 'health'.

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