kaiten_create_select_value

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

With no annotations, the description carries the burden of disclosing effects. It only states that a value is created, with no mention of uniqueness failure behavior, side effects, permissions, or response format. This is minimal for a write operation.

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 sentence with no filler words; the key action and resource are front-loaded. It is appropriately sized for the tool's simplicity.

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?

The tool is simple and the schema covers all parameters, but the description omits return value expectations and prerequisites such as property type and existence. An agent could invoke it, yet it is not fully complete without output schema or extra context.

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?

Input schema coverage is 100%, so the schema fully documents the four parameters. The description adds only a slight contextual link between select values and custom properties, which does not materially enhance what the schema already states.

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 specific action ('Create') on a specific resource ('select value') and scopes it to a custom property. This clearly distinguishes it from sibling tools like kaiten_update_select_value and kaiten_delete_select_value.

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 when-to-use or alternative guidance is provided. The description does not mention prerequisites such as the custom property needing to exist, nor does it direct the agent to kaiten_list_select_values for uniqueness checks.

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