refresh_book_metadata

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

With no annotations, the description must disclose all behavioral traits. It states 'Requires ADMIN' (auth need), but does not explain what 're-import' entails—whether it overwrites existing metadata, is destructive, has side effects, or returns a specific format. The description is too sparse to cover the behavioral burden.

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 extremely concise: two sentences, no filler. It front-loads the action and includes the essential access requirement. Every word contributes meaning, and there is no redundancy.

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?

Despite being a simple tool with one parameter and an output schema, the description lacks crucial context: no usage scenarios, no effects on existing data, no distinction from bulk metadata refresh. The presence of an output schema lightens the burden for return values, but the description does not cover behavioral or prerequisite context. Overall, it is under-specified for an agent to invoke correctly with confidence.

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%, so the description must compensate for explaining the `book_id` parameter. The description only says 'for a book', which does not clarify the parameter's format, purpose beyond identity, or any relationships. It adds minimal meaning beyond the bare schema definition.

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 ('Re-import embedded metadata') and the resource ('a book'). It distinguishes itself from sibling tools like refresh_library_metadata and refresh_series_metadata by specifying the per-book scope. The addition of 'Requires ADMIN' provides necessary access context.

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?

There is no guidance on when to use this tool versus alternatives such as refresh_library_metadata or update_book_metadata. The description implies usage for a single book, but does not explicitly state scenarios, prerequisites, or exclusions. No when-to-use or alternatives are mentioned.

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