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

No annotations are provided, so the description carries the burden — and it does disclose the returned signals (sync flag, height vs target, peer counts, versions), which is the key behavioral information for a read-only status probe with no output schema. It omits any note on auth, rate limits, or caching, so it is not fully complete.

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 reported fields, then two labelled clauses ('When to use', 'Do not use'). Dense but every clause earns its place, and the escalation path is stated in a single sentence.

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 parameterless read-only status tool with no output schema and no annotations, the description supplies both the content of the return (the enumerated fields) and the selection guidance against its nearest sibling. Nothing an agent needs to call it correctly is missing.

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 disambiguate; baseline is 4. The description correctly implies a no-argument call.

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 node state) and enumerates exactly what it reports: height vs target, sync flag, difficulty, txpool size, database size, monerod version, peer counts. It also names the sibling it is not (xmr_pool_status), so an agent can distinguish it from adjacent tools without opening a schema.

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?

Explicit 'When to use' (checking whether the XMR node is synced/healthy, or how large chain/txpool is) and an explicit 'Do not use' routing the mining/p2pool case to xmr_pool_status. Both the positive and negative conditions are stated.

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