bookshelf_create_indexer

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

Annotations already declare readOnlyHint=false, indicating a write operation. The description adds 'WRITE: this modifies your Bookshelf instance,' which reinforces the mutation but is largely redundant with the annotations. It adds generic context about modifying the instance but discloses no specific behaviors, side effects, or requirements beyond that.

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, with every sentence carrying some information: the operation, the query parameter, and the write warning. However, the brevity borders on under-specification, making it less useful than it could be. It is efficiently structured but sacrifices necessary detail.

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 create operation with an unconstrained body, an output schema, and multiple sibling tools, the description is incomplete. It does not explain what an indexer is, what fields the body should contain, the role of forceSave, or any expected response behavior. The minimal text leaves significant gaps for an agent to operate correctly.

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 only names 'forceSave' without explaining its meaning or effect. The 'body' parameter is not described at all, and since it allows arbitrary properties, the agent has no guidance on what to include. The description fails to compensate for the schema's lack of semantic detail.

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 states 'Create indexer' with a specific verb and resource, clearly distinguishing it from sibling tools like bookshelf_update_indexer, bookshelf_delete_indexer, and bookshelf_get_indexer. The name and description align, leaving no ambiguity about the operation.

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 through the verb 'create' but provides no explicit guidance on when to use this tool versus alternatives. There is no mention of prerequisites, scenarios, or any comparison to update/delete/list operations, so the agent must infer from context.

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