esphome_lvgl_get_styles

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

No annotations are provided, so the description must convey behavioral traits. The description states it 'gets' definitions, implying a read-only operation, but fails to mention any potential side effects, authentication requirements, rate limits, or whether the device must be online. For a simple getter, this is a minimal but insufficient disclosure.

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 extremely concise, consisting of a single sentence that front-loads the key information. Every word serves a purpose. However, it could be slightly improved by including a brief usage note without losing conciseness.

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?

Given that there is an output schema (mentioned in context), the description does not need to detail return values. However, it lacks important context such as prerequisites (e.g., the device must be configured with LVGL), error scenarios, or whether the device must be online. For a tool with only one parameter, this is minimally adequate but not thorough.

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 only parameter, 'device_name', has no description in the schema (0% coverage), and the tool description adds no additional meaning. It does not explain what constitutes a valid device name (e.g., friendly name vs. internal ID) or any expected format. The description fails to compensate for the schema's lack of documentation.

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's purpose: 'Get LVGL theme and style definitions from an ESPHome device config.' It uses a specific verb ('get'), identifies the resource ('LVGL theme and style definitions'), and specifies the source ('ESPHome device config'). This clearly distinguishes it from sibling tools like 'esphome_lvgl_get_pages' and 'esphome_lvgl_get_page_widgets'.

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 related sibling tools such as 'esphome_lvgl_get_page_widgets' or 'esphome_lvgl_get_pages'. It does not mention any prerequisites, typical use cases, or contexts where this tool is appropriate. This lack of usage guidance reduces its helpfulness for an AI agent deciding between tools.

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