reading_context

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

No annotations are provided, so the description carries the transparency burden. It discloses that the tool packages several read-oriented data sources and positions it as a non-authoritative convenience utility. It does not explicitly state that it is read-only or mention any side effects, auth needs, or performance implications.

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 short sentences with no filler. The component list is front-loaded, and the usage caveat is stated in the second sentence. Every part earns 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?

An output schema exists, so return-value details are not required in the description. The description states the tool's purpose and a key usage constraint, but it omits guidance on when to choose this aggregate over the individual sibling calls and leaves parameter semantics entirely to the schema.

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%, and the description does not explain book_id or chapter_uid at all. The parameter names are self-explanatory, but the description adds no meaning beyond the input schema, so it fails to compensate for the low schema coverage.

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 presents the tool as a convenient bundle ('便捷打包') of specific components: real progress, shared bookmarks, chapter plain text, existing ideas, and popular highlights. This conveys the resource and scope, and distinguishes it from the individual sibling tools by being a composite read package, though it does not name any sibling explicitly.

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 second sentence gives an explicit usage boundary: this is only a convenience tool and must not be treated as the default reading context; context organization belongs to the caller/frontend. However, it does not explicitly state when to prefer this tool over the individual sibling getters or name alternatives.

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