bookshelf_search_releases

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

The description adds a clear warning about modifying the instance ('WRITE: this modifies your Bookshelf instance'), which is valuable beyond the annotations. Annotations already indicate non-readonly, but the explicit statement reinforces the side effect. However, it does not detail what 'grab' entails or any external interactions.

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 concise sentences, front-loads the action and the write warning, and contains no unnecessary information. It earns a perfect score for efficiency.

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 having an output schema, the tool is a mutation with a generic body parameter. The description fails to explain the request format, expected identifiers, or behavior of 'grab'. The overall guidance is insufficient for correct invocation in a real scenario.

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 input schema contains only a generic 'body' object with no description or structure, and schema description coverage is 0%. The description mentions 'a book' and 'the given release' but provides no guidance on how to specify these in the body parameter, leaving the agent unable to construct a valid request.

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 phrase 'Trigger a release search for a book and grab the given release' which clearly identifies the action and resource. It is distinguishable from sibling tools like bookshelf_search (search for books) and bookshelf_list_release (list releases), though the meaning of 'given release' is slightly vague.

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 implies usage: when you want to search releases and grab a specific one. The explicit 'WRITE: this modifies your Bookshelf instance' warns against using in read-only contexts but does not name alternative tools or provide explicit when-not-to-use guidance beyond that.

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