create_tool

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, but it only says the tool creates something. It does not disclose side effects, persistence, permissions, validation behavior, or what happens after creation, leaving the agent with the bare meaning of the verb.

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 wastes space with a redundant second sentence and a vague third sentence that does not explain the creation workflow. It would be stronger as a single focused sentence stating the tool's purpose and perhaps a key constraint.

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 tool with five required parameters, no annotations, and no output schema, the description is under-specified. It lacks guidance on how created tools integrate with sibling tools, what the response will be, and when to use this instead of edit_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?

The input schema already provides 100% coverage with descriptions for all five required parameters, so the baseline of 3 applies. The tool description itself adds no parameter-level meaning, but the schema compensates adequately.

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 first sentence, 'Create a new tool,' clearly states the verb and resource, and the tool name plus siblings make its distinct role as creation versus fetch/edit/list/execute evident. However, the second sentence is a tautology that restates the name and adds no new meaning.

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 gives no guidance on when to use create_tool versus edit_tool or other siblings. It only vaguely states that created tools can be used to perform tasks, which does not help an agent decide when this tool is appropriate.

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