get_mesh_nodes

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no indication that the operation is read-only, no auth requirements, no note on whether mesh data is unavailable when EasyMesh is disabled. For a no-annotation tool this is a substantial gap, though the trivial no-arg read nature limits the damage.

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?

It is a single, front-loaded phrase with no waste, which is good, but this level of brevity crosses into under-specification rather than disciplined conciseness. A slightly longer sentence could have carried usage and scope without bloat.

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 simple no-arg, no-output-schema list tool the bar is low, but the description still omits what a mesh node record contains and how it differs from the device lists offered by siblings. An agent gets no help deciding between list_devices and this tool.

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 schema has zero parameters, so there is nothing for the description to document. Baseline 4 applies; no parameter semantics are missing.

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?

The phrase "EasyMeshノード一覧" identifies the resource (EasyMesh nodes) and implies a list operation, so the basic purpose is inferable. However, it never states a verb explicitly and gives no basis for distinguishing it from siblings like list_devices or list_endpoints, which an agent could easily confuse it with.

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?

There is no guidance on when to call this tool versus alternatives such as list_devices or router_overview. The description offers no context, prerequisites, or exclusion criteria, leaving routing entirely to inference.

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