esphome_lvgl_get_pages

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

With no annotations, the description must disclose behavioral traits. It indicates a read operation and mentions returns widget counts and background colors, but fails to mention if authentication is needed, performance characteristics, or potential failures.

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 that efficiently conveys the core purpose and key outputs without unnecessary words. It is front-loaded with the verb and resource.

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 get tool with one parameter and an output schema present, the description covers the return information (pages, widget counts, background colors). However, it lacks parameter documentation and usage context, making it incomplete for full autonomous use.

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 documentation coverage is 0%, and the description does not explain the device_name parameter. It only implies the device context but does not clarify format, constraints, or examples, leaving the agent without sufficient guidance for parameter input.

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 verb 'Get' and resource 'LVGL pages', specifies the scope (configured on an ESPHome device) and additional details (widget counts, background colors). It distinguishes from sibling tools like esphome_lvgl_get_page_widgets which retrieves widgets for a specific page.

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 on when to use this tool over alternatives, no prerequisites, no exclusions. For example, it doesn't clarify whether get_pages should be used first to get available pages before using get_page_widgets.

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