zwave_set_value

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

Discloses return status types, error condition (ValueError for unknown node), value type requirements, and example format. No annotations exist, so description carries full burden; missing details on invalid value type handling or side effects.

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?

Concise paragraph with bulleted args, front-loaded purpose, no wasted words. Every sentence adds value: outcome, error, prerequisites, example.

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?

Adequately covers behavior, return, error, and constraints for a simple set-value tool. Explains value_id source, status types, and queuing for sleeping nodes, despite no output schema.

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?

With 0% schema description coverage, the description provides meaningful context for all three parameters: explains node_id, value_id format, and value type constraints (number, bool, string). Fills in gaps beyond the schema's bare type definitions.

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 the tool sets a Z-Wave value and reports the outcome, with specific example value_id and return status. It distinguishes from sibling tools that handle associations, config parameters, or node info.

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?

Implied usage for setting Z-Wave values, but no explicit guidance on when to use vs alternatives like zwave_set_config_parameter or when not to use. Prerequisites mentioned but no exclusions.

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