List mesh nodes

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is fully covered. The description adds the useful detail that nodes include controller and extenders plus per-node metrics, but says nothing about result size, ordering, or what happens if no mesh system exists.

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 tight sentence that leads with the resource and then lists what each node exposes. Nothing is wasted and no critical information is buried.

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?

With no output schema, the description must convey return content, and it does list the per-node fields an agent would care about. Coverage is strong for a zero-param read tool; only edge behavior (empty/unsupported mesh, ordering) is unaddressed.

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 are no names or formats for the description to clarify; baseline 4 applies. Schema coverage is 100% with an empty property set, consistent with the description.

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 ('Get') and resource ('Mesh Wi-Fi system nodes') and enumerates the returned fields (client count, firmware, uptime, connection speed), so the agent knows exactly what this returns. It does not explicitly contrast itself with near siblings like get_wifi or get_clients, which is the only thing keeping it from a 5.

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 prerequisites, and no mention of alternatives among the many sibling list tools (get_wifi, get_clients, get_wifi_stations). Usage is only implied by the tool name.

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