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

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is covered. The description adds genuine context beyond that: which fields are omitted (contacts, addresses, payment settings) and that the text search is executed server-side by Rackbeat rather than locally. It does not mention rate limits or page-size ceilings, keeping it short of a 5.

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 with no filler. The projected-field list comes first and the exclusion list second, so everything is front-loaded and every clause carries information.

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, the description correctly compensates by enumerating the returned fields and the deliberately omitted ones. For a three-parameter read-only listing that is nearly complete; only pagination mechanics (page size, total counts) remain implicit.

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 0%, so the description must carry the load for page, limit and search; it only partly does. 'One bounded page' conveys the page/limit intent and 'search is sent to Rackbeat' conveys server-side matching semantics, but no defaults, maxima or matching rules (exact vs. partial) are given.

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 ('Read one bounded page') and resource ('customer') plus the exact projected fields: customer number, name, company, currency, barred/deleted status. That is far more precise than the title alone and is clearly distinct from sibling tools like rackbeat_orders or rackbeat_products, though it never explicitly routes the agent away from them.

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 explicit when-to-use guidance, no prerequisites, and no named alternative. 'Optional text search is sent to Rackbeat' hints at how to scope a query but doesn't tell the agent when this tool is the right choice versus a get-by-id or a sibling listing.

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