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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered; the description still adds real value by disclosing that the interface list is a bounded, truncated sample with flags and counts, and that it does not probe remote hosts. It does not mention cost or performance characteristics of the collection, so it stops short of a 5.

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 sentences, front-loaded with the use condition and the returned fields, then the alternative, then the behavioral caveat. No filler and nothing repeated from the title or schema.

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?

An output schema exists, so return-value structure need not be restated; the description covers the remaining burden — scope of the sample, truncation behavior, and absence of side effects or remote probing. An agent has everything needed to call this correctly and interpret the result.

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?

There is a single parameter (device) with 100% schema description coverage that already states it is the ReMCP device id returned by list_devices. The description adds nothing about the parameter, so the schema-coverage baseline of 3 applies.

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 verb+resource (network overview of a paired computer) and enumerates exactly what is returned: hostname, DNS servers, a bounded sample of interfaces/IPs, plus counts and truncation flags. It also names the sibling network_interfaces so the agent can distinguish the two without opening either 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?

Explicitly gives the triggering condition ("when the user asks for a quick network overview") and an alternative with its selecting condition ("Prefer network_interfaces for the complete inventory"). This is exactly the when-to-use / when-to-use-something-else routing an agent needs.

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