zwave_set_node_location

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

The description discloses that it raises ValueError for an unknown node id, which is a behavioral detail. However, with no annotations provided, it does not mention other traits like destructiveness, permissions, or reversibility, so transparency is moderate.

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?

The description is concise and well-structured: a one-line purpose, error behavior, then parameter definitions. Every sentence is necessary, no redundancy.

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 setter tool, the description covers purpose, parameters, and error handling. However, it lacks information about success behavior (e.g., return value) and side effects, which slightly reduces completeness.

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?

Schema coverage is 0%, but the description adds meaningful semantics by explaining each parameter: node_id as 'The Z-Wave node id, e.g. 5' and location as 'The new location for the node'. This compensates for the lack of schema descriptions.

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 description clearly states 'Set a node's location label.', specifying the verb (Set) and resource (node's location label). It distinguishes this tool from siblings like zwave_set_node_name and zwave_set_config_parameter by focusing specifically on location.

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?

No guidance is provided on when to use this tool versus alternatives. The description simply states its function without context on exclusions or comparisons with sibling tools, leaving usage implied.

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