send_command

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

No annotations are provided, so the description carries full burden. It only states behavior ('Send a command') but does not disclose side effects, authentication needs, rate limits, or whether the command is executed synchronously or asynchronously. The description is too brief for a mutation tool.

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 a single sentence, front-loading the action and target. It is efficient with no wasted words. However, brevity comes at the cost of completeness, which is acceptable given the tool's simplicity.

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 2-param tool with no output schema and no annotations, the description covers the basic purpose and provides partial parameter hints. However, it lacks details on valid command syntax, item naming, or expected outcome, making it minimally adequate but not complete.

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% (no parameter descriptions in schema). The description adds meaning for 'command' by listing examples (ON, OFF, numeric value), but 'itemName' is left completely undefined. This is marginal improvement over raw schema but insufficient for full understanding.

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 action ('Send a command') and the target ('to a single item'), specifying example command types (ON, OFF, numeric value). It implicitly distinguishes from sibling tools like 'execute_batch' (single vs batch) and 'schedule_command' (immediate vs scheduled), though not explicitly.

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 provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. There is no mention of valid items, command formats beyond examples, or contexts where this tool is appropriate.

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