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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that the call returns a docs URL and install command alongside the preview, which is genuinely new information, but it says nothing about failure behavior for unknown component names or how rendering is scoped to the chat session.

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?

Two sentences with no filler, and the primary action is front-loaded before the secondary return-value note. The second sentence is slightly tacked on with 'Also', but it carries information the agent would otherwise lack given there is no output schema.

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 two-parameter read-only tool with a fully covered schema, the description covers what it does and what comes back (preview plus docs URL and install command). The remaining gap is minor: no guidance on invalid names or on when a preview is preferable to get_component.

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 description coverage is 100%, so both parameters are already documented, including the example component name and the meaning of props. The description only restates that props are optional and adds no merge/precedence detail beyond what the schema's 'merged over the component's demo defaults' already provides, so the baseline of 3 applies.

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?

States a specific verb and resource: renders a live in-chat preview of a Remocn component, and notes it also returns a docs URL and install command. This is clearly distinct from metadata-style siblings like get_component or search_components, though the description never names them to sharpen the contrast.

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 phrase 'live in-chat preview' implies when this applies (visual rendering rather than lookup), but there is no explicit when-to-use rule, no exclusion of get_component, and no stated prerequisites such as needing a valid component name from search.

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