Get Chapter List

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that it retrieves the full table of contents but gives no information about read-only guarantees, failure behavior, authentication requirements, or whether the result includes chapter IDs or only titles. The description is too sparse to illuminate any behavioral traits beyond the bare operation.

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 focused sentence that is immediately informative and free of fluff. It is front-loaded with the core action and object, though it is so terse that it misses opportunities to add routing or edge-case context without bloating.

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 very simple tool with one parameter, 100% schema coverage, and an output schema, the description is sufficiently complete for selection and invocation. The main missing element is guidance on how to obtain book_id (e.g., via search_novels), but the existing structure already covers the mechanics of the 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?

The schema fully documents the only parameter, book_id, with a reasonable description, and the tool description does not contradict or add to it. Since schema_description_coverage is 100%, the baseline of 3 is appropriate; the description offers no extra semantic meaning beyond the schema.

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') and a clear resource ('the full table of contents for a novel'), which directly distinguishes it from siblings like read_chapter (a single chapter), get_novel_info (general novel metadata), search_novels, and get_novel_by_name. An agent can unambiguously tell what this tool returns.

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 intended use is implied by the description and name: when the agent needs a complete table of contents for a given novel. However, it provides no explicit when-to-use or when-not-to-use guidance, and no alternatives are named or contrasted. The context is clear but exclusions are absent.

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