bookshelf_bulk_update_indexer

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

Annotations already indicate readOnlyHint=false, so the description's 'WRITE: this modifies your Bookshelf instance' is largely redundant. No additional behavioral details are provided, such as whether the update is idempotent, how partial updates are handled, or what happens to unspecified fields.

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 very short, but this is under-specification rather than conciseness. The first sentence is a meaningless tautology, and the second sentence adds minimal value.

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 bulk update tool with a free-form body and no schema descriptions, the description is completely inadequate. The agent cannot determine what request body to construct, whether it expects an array or object, or what effects the operation will have.

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 has a single 'body' parameter with no description and additionalProperties=true. The description does not explain how to structure the body or what fields are supported, leaving the agent completely without guidance.

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 'Bulk update indexer bulk' merely restates the tool name and adds redundant 'bulk'. It does not explain what a bulk update entails or how it differs from the single-update endpoint (bookshelf_update_indexer). The 'WRITE' note is about effects, not purpose.

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?

No guidance is given for when to choose this tool over alternatives like bookshelf_update_indexer or bookshelf_bulk_delete_indexer. There is no mention of use cases, prerequisites, or exclusions.

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