get_elements_by_renderer

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states a read operation ('Get'), but doesn't cover critical aspects such as whether it requires authentication, potential rate limits, pagination behavior, error conditions, or what happens if the rendererID is invalid. This leaves significant gaps for safe and effective use.

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, direct sentence with zero wasted words. It's appropriately sized for a simple tool and front-loads the core purpose without unnecessary elaboration, making it easy to parse quickly.

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 the tool's complexity (a read operation with one parameter) and lack of annotations or output schema, the description is incomplete. It fails to explain return values (e.g., list format, element structure), error handling, or dependencies, which are essential for an agent to use it correctly without trial and error.

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 has 100% description coverage, with 'rendererID' documented as 'Renderer ID'. The description adds no additional meaning beyond this, such as explaining what a renderer is or where to obtain its ID. Since schema coverage is high, a baseline score of 3 is appropriate, as the description doesn't compensate but also doesn't detract.

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 'Get all elements for a specific renderer' clearly states the action (get) and resource (elements), but it's vague about what 'elements' means in this context (e.g., UI components, DOM nodes). It distinguishes from siblings like 'get_element_by_id' by implying a bulk fetch, but lacks specificity on scope or format.

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 on when to use this tool versus alternatives. For example, it doesn't explain if this should be used instead of 'get_component_tree' or 'search_components' for renderer-specific queries, nor does it mention prerequisites like needing an active connection or renderer availability.

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