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

Annotations already declare readOnlyHint, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds real value by disclosing the breadth of the payload (a large multi-section read), but says nothing about response size, ordering, or what happens if the store id is invalid.

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?

One dense sentence with no filler, and the most searched-for items (contact, payment, shipping) are listed first. It lacks a leading verb phrase, so the agent must infer the action from the name rather than the opening words.

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?

With no output schema, enumerating the returned sections is exactly the right compensation, and the required param is fully documented in the schema. Only the absent routing guidance against overlapping siblings keeps it short of complete.

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 schema already explains that 'store' comes from find_store or search_products, so the description need not repeat it. 'of one DMCommerce store' reinforces the single-store scoping but adds no syntax or format 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 enumerates precisely what the tool returns — contact details, payment methods, shipping rules, benefits, FAQ, offers and policy pages — for a single store, which is far more specific than the name alone. It scopes the result to 'one DMCommerce store' but never explicitly distinguishes itself from siblings like find_store or read_store_page, which also deal with store-level data.

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 statement of when to reach for this tool versus find_store, read_store_page, quote_shipping or list_promotions, all of which overlap with the returned content. Usage is only inferable from the enumerated payload.

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