create_libraries_order

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

Annotations already indicate this is not read-only, not destructive, and idempotent; the description adds no side-effect details, permissions, or conditions. It does not contradict the annotations, but it reveals nothing about what creating or acting on a libraries order actually changes or requires.

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 short and mostly front-loaded, but the opening sentence merely restates the tool name and adds little value. The endpoint and body guidance are useful, but the tautological first line keeps this from being tightly effective.

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 an operation with a generic body, a large sibling set, and no behavioral detail, this description is incomplete. It leaves the meaning of 'libraries order' unexplained and relies on the agent to go elsewhere to understand both the payload and the operation's effect.

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?

The input schema only defines an open-ended body object, and schema description coverage is 0%. The description tells the agent to read the matching GET or /schema endpoint to discover expected fields, which is a helpful pointer, but it does not describe the body semantics or any concrete fields, so it only partially compensates for the schema gap.

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 only restates the tool name ('Create or act on libraries order') and gives the endpoint path. It never says what an 'order' is, whether it means reordering libraries or creating an order object, or what 'act on' covers. The broad phrasing fails to distinguish this from close siblings like create_libraries or patch_libraries_by_id.

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 only guidance is to read the matching GET or /schema endpoint first, which is a prerequisite rather than a usage rule. There is no explanation of when to use this tool vs. alternatives, nor any explicit exclusions. An agent is left to infer the appropriate context from the name and endpoint.

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