orders_fulfill

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

The only behavioral disclosure is that the tool is gated behind a higher plan. No information is given about side effects, output, or any other behavior. Since no annotations are provided, the description carries the full burden and falls short.

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 short sentence, which is concise. However, it is under-specification rather than truly concise; it contains minimal substantive content and does not help the agent understand the tool.

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 description is essentially a lock-out message. It tells the agent the tool is unavailable and to check license_status, but it fails to explain what orders_fulfill actually does. With no output schema or annotations, this leaves a significant gap in understanding.

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 is empty, so there are no parameters to describe. The description adds nothing, but with zero parameters the baseline of 4 is appropriate.

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 does not state what the tool does. It only mentions a plan upgrade requirement, leaving the agent to infer functionality from the name 'orders_fulfill'. No verb or resource is specified.

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 explicitly states the tool is not currently available (requires a higher plan) and directs the agent to use 'license_status' to see options. This provides a when-not and an alternative, but it does not explain when the tool should be used once the upgrade is obtained.

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