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

With no annotations, the description carries the burden of disclosure. It reveals that the tool toggles categories, affects tool availability, and that changes apply on the next request. This is useful behavioral context. It could be more explicit about side effects (e.g., whether disabling removes tools from the current context), but the description covers the key behavior.

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 three concise sentences, front-loaded with the primary action. It includes all necessary information without any fluff or redundancy, making it easy to scan and understand.

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 simple toggle tool, the description is fairly complete. It explains how to use it, the categories, and that tools become available on the next request. It does not explain return values, but the output schema is absent and the tool's effect on tool availability is more important. Slight gaps include no mention of error cases or reversibility, but these are minor.

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%, but the description compensates by explaining 'Enable or disable' (mapping to the action parameter) and listing all category values, including the default state for books. It adds meaning beyond the enum literals by indicating the purpose of each parameter. More detail on what each category contains would be helpful, but the sibling tool names provide some hints.

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 states the tool's purpose: 'Enable or disable a BookLore tool category' with a specific verb and resource. It also lists the available categories and distinguishes itself from sibling tools that perform book operations, making its role as a meta-tool unmistakable.

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 gives explicit usage context: 'Call this to activate a category before using its tools' and advises re-checking available tools after enabling. It also notes that books is enabled by default, which helps with when to use the tool. However, it does not explicitly mention when not to use it or alternative approaches, though the intent is clear.

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