inspect_book

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

No annotations exist, so the description carries the full burden. 'Inspect' and 'verify' imply a non-mutating operation, and it discloses the two things it produces (accessibility status, sample page info), but it says nothing about failure modes (unreachable URL, invalid book id), rate limits, or auth requirements.

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?

A single front-loaded sentence naming the resource then the two outputs, with zero filler. Appropriate size for a two-parameter inspection tool.

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?

With no output schema and no annotations, the description is the only source for return-value behavior, and 'sample page info' is left undefined. For a simple read-only check this is minimally viable, but an agent cannot predict the response shape or error signaling.

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% with only two params, both documented in the schema itself. The description adds no format hints (e.g., how a book identifier is formed vs. base_url), so baseline 3 applies.

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?

Specific verb ('Inspect') plus resource ('a Matricula book'), with the two concrete outcomes named: accessibility verification and sample page info. This clearly separates it from download_page/download_range siblings, though it never names an alternative 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 phrase 'verify accessibility' implies a pre-flight check before downloading, but the description never states when to call this versus inspect_page or download_page. Usage is inferable rather than declared.

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