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

With no annotations provided, the description carries the full burden. The 'readonly-owner' tier hint and 'Billable services' wording indicate read semantics, which is helpful. However, it doesn't disclose pagination semantics, default page sizes, or whether results are ordered/filtered in any particular way.

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 sentences with zero waste. Front-loaded with the core purpose, then maps to the endpoint and tier. This is appropriately concise.

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 three-optional-parameter list tool with no output schema, this is reasonably complete given the tier hint covers safety. However, the 0% schema description coverage plus undeclared pagination defaults and no filter explanation leaves gaps an agent would have to discover at runtime.

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 description must compensate, and it does not. None of the three parameters (page, page_size, category_id) are explained. The purpose of category_id is inferable from the tool's purpose, but no explicit guidance is given on filter semantics or pagination constraints.

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?

Clear verb+resource ('List billable services configured in the price book'). The purpose is specific and distinct from siblings like list_materials or list_price_forms, though it doesn't explicitly differentiate itself from these names.

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 when-to-use or when-not-to-use guidance. The tier hint '[tier: readonly-owner]' implies it's a read-only list operation, but there's no mention of pagination behavior, filtering alternatives, or context in which this would be preferred over other list tools.

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