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. The description adds nothing beyond that: no statement of what content is returned, in what form, or whether the 'course' topic is a rate or a training course.

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?

It is a single short sentence with no padding, so nothing is wasteful, but it is a bare enumeration rather than a structured statement of purpose. Being short here comes at the cost of under-specification.

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?

This is a simple read-only tool with one optional enum parameter and no output schema, so little explanation is required. Still, with no output schema the description should indicate that it returns textual policy information per section, which it never says.

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 coverage is 100% and the topic enum already documents every accepted value with its own description. The description merely repeats the same list of topics, adding no format, default-behavior, or interpretation detail beyond the schema.

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 is a comma-separated topic list (payment, delivery, wholesale, pickup, contacts, glass polishing course) with no verb or statement of what the tool actually returns. It roughly conveys scope, and the mention of delivery helps distinguish it from siblings like delivery_quote, but the agent must infer the action from the name alone.

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 exclusions, and no reference to any alternative tool. An agent cannot tell from this text whether to call store_info or delivery_quote/order_status for shipping-related questions.

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