-]Output schema / properties / items / items / typeRemoved value: -"object"Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare the operation as read-only, idempotent, and non-destructive. The description adds useful behavioral context beyond that: the item is published, the response includes source links, dated prices, variants, media, and referral disclosures, and live availability is not checked.
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 two tight sentences with no wasted language. The retrieval scope and ID source are front-loaded, followed by the useful contents and limitations.
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?
An output schema exists, so return values need not be exhaustively described. The description still summarizes what the item includes and states important limitations, making it complete enough for an agent to invoke the tool correctly.
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 provides a pattern for the ID but no textual description, so the description must compensate. It does so partly by explaining that the ID is stable and is returned from search_curator, which is meaningful guidance beyond the schema. It does not elaborate on the slug format or invalid-ID behavior, but the schema pattern covers those constraints.
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 and resource: retrieve one published Curator item. It distinguishes this from search_curator by requiring a stable ID returned from that search, and from render_curator_items by explicitly saying it does not render UI.
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?
It tells the agent where the required ID comes from (search_curator) and clarifies two important exclusions: it does not verify live availability and does not render UI. This effectively routes the agent between this tool and its siblings.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
