bookshelf_bulk_delete_bookfile

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

The description repeats the destructive nature with 'DESTRUCTIVE: this deletes data,' but the annotations already include destructiveHint=true and readOnlyHint=false. It adds no new behavioral details such as irreversibility, scope of deletion, or side effects, so it does not meaningfully go beyond the structured annotations.

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 text is short but poorly structured: 'Bulk delete bookfile bulk' is redundant and could be streamlined. The capitalization of 'DESTRUCTIVE' is unnecessary and the warning adds little beyond the tool name and annotation. It is more underspecified than appropriately concise.

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 description fails to explain the expected input payload, which is critical for a destructive bulk operation. It also does not provide any context about how records are selected for deletion or what the consequences are, making the tool risky to invoke without external knowledge.

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 has a single 'body' object with additionalProperties allowed, but the schema provides no parameter descriptions (0% coverage). The description does not explain what the body should contain (e.g., IDs, filter criteria), leaving the agent without the information needed 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 clearly identifies the operation as a bulk delete targeting bookfiles, using the verb 'delete' with the resource 'bookfile.' This differentiates it from single-delete tools like bookshelf_delete_bookfile and bulk-update tools. However, the wording is awkward with the redundant trailing 'bulk,' and it does not explicitly explain what 'bulk' entails.

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 usage guidance is provided. The description does not mention when to use this tool instead of alternatives like bookshelf_delete_bookfile or other bulk-delete operations, nor does it state any prerequisites or selection criteria for the affected records.

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