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

With no annotations, the description carries the full burden, and it discloses the scope of the returned dataset (both sidechains, node workers, fee, non-custodial flag) which is the key behavioral trait. 'Status' implies a read-only, non-mutating call, but it never states this explicitly nor mentions latency, data freshness, or auth needs, so it falls just short of full disclosure.

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?

Front-loaded with the resource and its scope, then the use/avoid routing, so the agent gets the decision-relevant information first. The field enumeration is dense but each item is informative; the only minor cost is the long single clause listing returned values.

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 communicate what comes back, and it does so by enumerating the per-sidechain metrics, node workers, fee, and flag. Combined with the sibling routing, an agent has everything needed to call it correctly.

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, which is the baseline-4 case; there is nothing to document and the description correctly implies a no-argument status call rather than listing any options.

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?

States a specific resource (Monero p2pool mini+nano sidechains plus network state) and enumerates exactly what it exposes: per-sidechain hashrate, miners, height/difficulty, blocks found, last block age, workers, fee, and the non-custodial flag. It also names the sibling it is not (xmr_node_status), so an agent can distinguish them without opening schemas.

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?

Gives explicit 'When to use' triggers (solo/p2pool mining economics, sidechain health, picking a stratum endpoint) and an explicit 'Do not use' routing plain node RPC state to xmr_node_status. Both the positive and negative conditions are stated, leaving nothing to inference.

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