Annotate Isbn Openlib

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing beyond the data source. The verb 'annotate' implies enrichment or attachment of data, but the description never says whether anything is written, where results go, or whether external network calls or rate limits apply.

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?

A single short fragment that is front-loaded with the source and scope. Nothing is wasted, though the fragmentary phrasing means it is terse to the point of omitting the verb.

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?

An output schema exists, so return values need not be described, and the single parameter is fully covered. What remains missing is behavioral context and routing versus annotate_isbn_google, leaving the definition only minimally viable for its sibling-rich environment.

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 100%, and the single isbn parameter is already documented as accepting ISBN-10 or ISBN-13 with hyphens allowed. The description adds no format detail beyond the schema, so the baseline of 3 applies.

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?

Names a specific resource (book metadata), a specific source (Open Library), and scoping (one ISBN), which lets an agent distinguish it from the sibling annotate_isbn_google. It lacks an explicit verb for what 'annotate' actually does, but the resource+source pairing is clear.

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?

There is no guidance on when to prefer Open Library over the sibling annotate_isbn_google, nor any stated prerequisite or output condition. The agent must infer the choice purely from the source name embedded in the tool title.

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