get_asset_library_item

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

There are no annotations, so the description carries the disclosure burden. It reveals that the operation is a read-like 'resolve' that returns multiple components, but it does not explicitly state that it is side-effect-free or describe error/not-found behavior. Its read intent is reasonably clear from the verb and 'get_' naming.

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, front-loaded sentence with no filler. Every listed component is informative, and no redundant language is present.

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 low complexity (one parameter, no output schema, no annotations), the description is mostly complete: it states the action and the returned artifacts. It could be improved by noting that the id likely comes from get_asset_library, but that is a minor gap for a straightforward retrieval tool.

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 schema only documents id as a non-empty string, so description must add meaning. 'Library item' weakly ties the id to the item being resolved, but the description does not explain where to obtain the id or any expected format. It partially compensates for the 0% schema coverage but not fully.

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 states a specific verb ('Resolve') with a clear resource ('one library item') and enumerates what is returned: README, preview, sprite sheet, and variants. The singular 'one' distinguishes it from the sibling get_asset_library, which is presumably a list operation.

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 makes it clear this is the tool for retrieving a single library item's full set of associated artifacts, which is useful context for tool selection. It does not explicitly call out alternatives or say 'use get_asset_library for listing', but the singular framing implies that distinction.

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