get_novel_stats

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

With no annotations, the description carries the full burden of behavioral disclosure. It does state the operation is a read ('获取'), the data categories included, and the default selection behavior. It does not disclose error behavior, auth requirements, or the exact output structure, which is some gap for a tool with no output schema.

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 two concise sentences with no filler. It front-loads the core purpose and details in the first sentence, and the default behavior in the second, with every word earning its place.

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 low-complexity tool with two optional parameters and no output schema, the description provides a solid overview of what data will be returned and how book_id behaves. It could be more complete by describing the shape of chapter details or behavior when no novel is selected, but the essentials for selecting and invoking the tool are present.

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%, so the schema already documents both parameters. The description reinforces the book_id default and chapter detail meaning but adds no meaningful semantics beyond what the input 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?

The description clearly states the tool gets novel reading statistics, enumerating the specific returned categories: book-level overview (read_count, word count, serialization status) and per-chapter reading/following details. This distinguishes it from siblings like list_novels and list_chapters, which are about listing rather than statistics.

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 description implies the tool is for reading statistics and clarifies the default behavior when book_id is omitted, which helps invocation. However, it does not explicitly state when to prefer this tool over alternatives such as list_chapters or get_current_novel, nor does it provide exclusions.

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