esphome_device_info

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

With no annotations, the description carries the full burden for behavioral disclosure, but it only states 'Get detailed info'. It does not mention whether the operation is read-only, what data is included in the response, or any permission requirements, offering minimal value beyond the tool name.

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, focused sentence that is immediately understandable and contains no unnecessary words. It is appropriately front-loaded with the action and subject.

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 read tool with two well-described parameters, the description is minimally viable. However, it lacks usage context and expected output specifics, and without annotations or an output schema, it leaves ambiguity about what 'detailed info' entails, making it less complete for agent decision-making.

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 input schema provides full descriptions for both parameters (device_id and esphome_device) at 100% coverage. The tool description adds no additional parameter meaning, so the baseline score of 3 is appropriate.

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 uses a specific verb 'Get' and resource 'detailed info about an ESPHome device', making the basic purpose understandable. However, 'detailed info' is somewhat vague and does not explicitly distinguish from sibling tools like esphome_get_states, which also fetches device-specific data.

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 about when to use this tool versus alternatives such as esphome_get_states or esphome_list_devices. The description offers no prerequisites, exclusions, or contextual hints, leaving the agent to infer the appropriate use case.

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