bin_create

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

No annotations are provided, so the description must handle transparency alone. It discloses the core behavior: creating a bin under a parent or root. However, it does not mention potential side effects, required permissions, or behavior when the parent does not exist. For a creation tool, this is adequate but not exhaustive.

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, front-loaded sentence that conveys the essential action and key parameters with no redundancy. Every word contributes meaning, making it highly efficient.

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 tool with no output schema and no annotations, the description covers the primary action and location. It does not mention the return value or error cases, but these are less critical given the tool's simplicity. The context is mostly complete for an AI agent to use correctly.

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 coverage is 0%, meaning the description does not explain parameter meanings beyond implicit references. The description mentions 'parent' but does not specify that 'name' is required or provide details on default values or types. With only 2 parameters, the description should compensate, but it falls short.

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 action ('Create a bin') and the resource ('bin'), and specifies the location ('under the given parent, or under the root bin by default'). It effectively distinguishes from sibling tools like 'bin_delete', 'bin_move', and 'bin_set_current' which handle different operations.

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 implies when to use the tool (when creating a bin) but does not explicitly state when not to use it or mention alternative tools. No exclusion criteria or context for selection among similar tools like 'bin_tree' or 'bin_current' is provided, leaving the agent to infer usage.

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