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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. With no output schema, the topic list is the only signal about what data comes back, which is genuine added value. However, nothing is said about format, granularity, or freshness of the returned content.

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?

Extremely short and front-loaded, with no wasted words, but it is a sentence fragment that reads like a table-of-contents entry rather than a statement of purpose. Brevity is achieved at the cost of grammatical clarity.

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?

For a simple zero-parameter, read-only lookup there is little to explain, and annotations cover the safety profile. Still, with no output schema the description should say plainly what the agent gets back (policy text, contacts, review summaries) — the topic list only gestures at it.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline applies. The topic list does usefully scope what this parameterless call returns.

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 enumerates topic areas (shipping, payment methods, physician review, quality testing, contact) which conveys what the tool surfaces, but it is a noun-phrase fragment with no verb, so it never states that it *returns* or *retrieves* this information. The name/title 'store_info' / 'Store information' is itself ambiguous between 'shop information' and 'to store information', and the description does not resolve that.

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?

No guidance on when to call this versus the siblings create_checkout_link or list_products, no exclusions, and no stated prerequisites. The agent must infer that this is a general FAQ/policy lookup.

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