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 fully covered by structured data. The description adds nothing beyond that — no scoping behavior, no pagination, no note on how the optional business_id interacts with token scope, which the schema flags as a real constraint.

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?

A single front-loaded sentence with zero waste, but also zero substance beyond restating the title. It is concise to the point of under-specification rather than efficient communication.

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?

The tool has four optional parameters and a rich annotation set, and an output schema covers return values, so the return side needs no description. However, the core ambiguity — what a "product" is in this catalog and how results relate to a business — is never resolved, leaving the agent to guess the domain semantics.

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 all four optional parameters (query, category, inventory, business_id) are already documented, including the token-scoping caveat on business_id. The description contributes no additional parameter meaning, which is acceptable at this coverage level but not additive.

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 gives a specific verb ("List") and a resource ("agent product catalog"), but "agent product" is left undefined — it is unclear whether these are products an agent sells, products in an agent's catalog, or agent-related SKUs. Nothing distinguishes it from adjacent listing tools such as list_agents or list_plans.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives. An agent must infer from the name alone that this is the tool for enumerating a catalog.

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