create_library

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only hints at password encryption but says nothing about side effects, authentication requirements (even though account_token and session_token exist in the schema), or what happens if the library already exists. This is severely insufficient.

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 extremely short, which could be seen as concise, but it is under-specified rather than efficiently structured. It lacks any explanatory content that would justify its brevity. The single sentence does not earn its place because it fails to convey essential information.

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 creation tool with 4 parameters, no annotations, and no output schema, this description is woefully incomplete. It does not explain what a library is, the purpose of the password, token requirements, or expected behavior. An agent cannot reliably invoke this tool based on this description alone.

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%, so the description must explain the parameters. It does not mention name, password, account_token, or session_token at all. The parenthetical about password being encrypted is too vague to convey its role or constraints. The agent is left with only parameter titles, which are insufficient.

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 states a clear verb+resource ('Create a library'), so the primary action is unambiguous. However, the parenthetical '(password -> encrypted)' is cryptic and does not clarify what a library is or how this tool differs from siblings like auth_add_library or auth_register_library, so it fails to distinguish itself.

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 use this tool versus alternatives. The description never mentions prerequisites, context, or why one would choose create_library over auth_add_library or other sibling tools. An agent has no basis for deciding between them.

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