A3.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so safety is covered. The description adds genuinely new behavioral context: results come from a local snapshot, it is auto-refreshed when missing, and snapshots older than 24 hours are flagged stale — an important data-freshness caveat. It does not mention auth requirements or whether refresh writes back to the snapshot, keeping it at 4.

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

Conciseness4/5

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

Three sentences, beginning with purpose and then the caching behavior, with no filler. The middle sentence ('refreshed automatically when missing') is slightly compressed and could be misread, but overall it is appropriately sized and front-loaded.

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

Completeness4/5

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

An output schema exists, so return values need not be described, and the caching/staleness semantics are covered well. Only minor gaps remain, such as whether the refresh flag persists or updates the snapshot, so it is nearly complete but not exhaustive.

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

Parameters3/5

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

Schema description coverage is 100% for the single 'refresh' parameter, so the schema already documents its meaning and default. The description restates the refresh behavior without adding format, cost, or side-effect detail beyond what the schema provides; baseline 3 is appropriate.

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

Purpose4/5

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

States a specific verb and resource ('List the products saved as favorites on the account'), and the 'favorites' resource is distinct enough from siblings like list_orders, search_products and get_product that an agent can route correctly. It stops short of explicitly naming a sibling or boundary it is not, so it lands at 4 rather than 5.

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

Usage Guidelines3/5

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

The description explains the default data source and how to override it ('Pass refresh: true to fetch the current list'), which is useful context for invoking the tool. However, it gives no explicit when-to-use vs when-not guidance and never mentions the relevant alternatives (search_products, get_product), so usage is only implied.

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