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

With no annotations, the description carries the full disclosure burden. It usefully reveals the auth requirement (Bearer token plus phone) and the recency scoping, and 'list' implies a read-only operation, but it says nothing about rate limits, error behavior, or the paging quirk that the schema flags. Partial coverage for a no-annotation tool.

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?

Two tight sentences/fragments with the resource and status axes front-loaded and no filler. Nothing is wasted, though the telegraphic style leaves behavioral gaps the length budget could have covered.

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 three-parameter listing tool with a fully-described schema and no output schema, the description covers purpose, return shape (status axes), and auth prerequisites. The main omission is any note on return volume or the ignored page parameter, but the schema already documents the latter.

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 the baseline is 3. The description restates that phone is required (already in the schema's required list) and adds no syntax or format detail for phone, page, or limit, so it does not exceed what the schema already provides.

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?

States a specific verb+resource ('orders' for a customer) and enriches it with the 6-axis status breakdown, so an agent knows exactly what data shape comes back. It does not explicitly contrast with siblings, though the sibling set (get_cart, list_products, list_brands, etc.) targets different resources, which limits ambiguity.

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?

The word 'Recent' implies the tool is scoped to the most recent orders and 'Bearer + phone required' signals the auth/customer prerequisite. However, there is no explicit when-to-use guidance, no exclusions, and no pointer to alternatives such as get_cart or get_customer for related lookups.

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