Read-onlyIdempotent

Display up to 12 Curator finds as interactive cards in chat. First call search_curator or get_curator_item and choose matching IDs. Pass only those IDs; the server supplies authoritative public facts. Preserves the requested order. Users can filter, inspect, select and discuss items; selections are temporary and are not a saved wishlist.

A4.7/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds genuinely new behavior: the server supplies authoritative public facts for the IDs, the requested order is preserved, and selections are temporary rather than a persisted wishlist — all beyond what annotations convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tight sentences, front-loaded with the action and limit, followed by the workflow precondition and the behavioral caveats. No filler or restatement of the title.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value explanation is unnecessary, and the description covers the remaining gaps: item cap, prerequisite calls, order preservation, and the ephemerality of selections. Nothing an agent needs to invoke this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% for the single `ids` parameter, so the description carries the burden: it explains the IDs must be chosen from prior search/get results, that only IDs should be passed (the server enriches the rest), and that ordering is meaningful. It also restates the 12-item cap. It does not clarify the ID format beyond the schema's pattern, keeping it short of a 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ("Display up to 12 Curator finds as interactive cards in chat") plus the cardinality limit, which immediately distinguishes it from the search and fetch siblings. An agent knows this is the rendering step, not a data-retrieval step, without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly prescribes the prerequisite workflow: "First call search_curator or get_curator_item and choose matching IDs," naming both alternatives by name and the condition that selects each. It also implicitly excludes using this tool as a lookup by requiring IDs to come from a prior call.

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