books_get_bills

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

With no annotations, the description must disclose behavior. It does not mention pagination (despite `page` and `per_page` parameters), which could mislead users into thinking all bills are returned at once. No information about filtering limits or response format is provided.

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?

The description is a single short sentence, so it is concise, but it lacks structure: no separation of purpose, usage, or parameter context. It is not overly verbose, but it is too terse to be considered well-structured.

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 tool with 12 parameters and no output schema, the one-sentence description is wholly insufficient. It doesn't explain return values, pagination, or parameter usage, making it impossible for an agent to invoke this tool correctly beyond a basic call.

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?

There are 12 parameters with 0% schema description coverage. The description provides no explanation of any parameter, leaving users to guess at the meaning of `filter_by`, `sort_column`, `search_text`, etc. This is a complete failure to compensate for the schema gap.

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 uses a specific verb 'Get' with resource 'all bills' and context 'Books', clearly distinguishing it from the singular sibling tool `books_get_bill`. This makes the tool's purpose unambiguous.

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 is provided on when to use this tool versus alternatives like `books_get_bill` or how it relates to other bill-related tools. There is no mention of filters or intended use cases.

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