remove_books

Remove books from a Calibre library by specifying comma-separated IDs. Requires confirmation to delete; optionally skip the recycle bin for permanent removal.

Instructions

Removes books from the library by id (comma-separated). DESTRUCTIVE: requires confirm=true. permanent=true skips Calibre's recycle bin.

Input Schema

NameRequiredDescriptionDefault
book_idsYesIds to remove, comma-separated.
confirmNoMust be true to actually delete.
permanentNotrue = do not use the recycle bin.
Behavior5/5

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

With no annotations, the description fully discloses destructive behavior, the confirmation requirement, and the recycle bin bypass option, providing essential behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no wasted words. Critical information is front-loaded: verb, resource, destructiveness warning. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is straightforward, and the description covers all key behavioral aspects. However, it does not mention return values or error handling, which could be useful given no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description adds meaningful value beyond the schema: it specifies that book_ids are comma-separated, confirm must be true to execute, and permanent skips the recycle bin. This directly aids parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Removes' and the resource 'books from the library', distinguishing it from sibling tools like add_book or remove_tags.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It explicitly mentions destructiveness and the need for confirm=true, and explains the effect of permanent=true. However, it does not explicitly state when not to use this tool or provide alternatives.

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