readwise_get_book_highlights

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

No annotations are provided, so the description carries full burden for behavioral disclosure. While 'Get all highlights' implies a read operation, it doesn't specify whether this returns paginated results, what format the highlights come in, whether it requires authentication, or any rate limits. The description is minimal and lacks important operational context.

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, efficient sentence that communicates the core functionality without any wasted words. It's appropriately sized for a simple retrieval tool and gets straight to the point.

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 simple single-parameter retrieval tool with no output schema, the description provides the basic purpose but lacks important context about return format, pagination, or how it differs from sibling tools. It's minimally adequate but leaves significant gaps in understanding the tool's full behavior and appropriate usage scenarios.

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 description coverage is 100%, with the single parameter 'bookId' clearly documented in the schema. The description adds no additional parameter information beyond what's already in the structured schema, so it meets the baseline expectation without adding extra value.

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 action ('Get all highlights') and target resource ('from a specific book'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'readwise_list_highlights' or 'readwise_search_highlights', which likely have overlapping functionality.

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 provides no guidance on when to use this tool versus alternatives. With siblings like 'readwise_list_highlights' and 'readwise_search_highlights' available, there's no indication of when this specific book-focused retrieval is preferred over more general highlight listing or searching tools.

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