transfer_library

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

Annotations set readOnlyHint=false and openWorldHint=true, indicating a mutating operation with potential side effects. The description adds little beyond the verb 'transfer', failing to disclose whether the previous owner loses access, if the action is reversible, or success indicators.

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 a single sentence with no extra words, achieving high conciseness. However, it could be restructured to front-load key info like side effects or usage context without increasing length.

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?

Given the absence of an output schema, the description should clarify return values, error handling, or confirmation of ownership transfer. It does not, leaving the agent with incomplete context for a mutating tool.

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 67% (library_id and email have descriptions). The tool description does not add meaning beyond what is already in the schema; it does not explain the 'response_format' parameter or parameter interactions.

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 function: transferring library ownership. It uses a specific verb ('transfer') and resource ('ownership'), distinguishing it from siblings like 'create_library' or 'delete_library'.

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 provided on when to use this tool versus alternatives like 'edit_library' or 'update_permissions'. The description does not mention prerequisites, such as needing current owner permissions, nor exclusions.

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