FulfillmentInbound_createInboundPlan

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

With no annotations, the description carries the full burden, but it only reveals that the tool runs in a Kuudo deployment and creates a plan. It does not disclose side effects, required prerequisites, permissions, persistence behavior, or what happens on success, leaving the agent without a clear model of invocation.

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 contains no filler, but the actionable statement 'Creates an inbound plan' is placed last, after the cryptic 'Catalog entry' and 'Runs in your Kuudo deployment, not here.' This is not well front-loaded for agent comprehension.

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 create operation with no annotations and no output schema, the description is too thin. It does not describe expected inputs, workflow, return behavior, or prerequisites. The environment note is unexplained and may even discourage invocation, so an agent cannot confidently call this tool based on the description alone.

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 defines zero parameters and has 100% schema coverage, so the baseline for zero parameters is 4. The description adds no parameter detail, but none is required by the schema. The additionalProperties:true field is a potential gap, but with no declared properties it does not significantly lower this score.

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 contains a specific verb and object: 'Creates an inbound plan,' which distinguishes it from sibling list/get/update/cancel inbound-plan tools. However, the prefatory 'Catalog entry' and 'Runs in your Kuudo deployment, not here' obscure whether this tool actually executes in the current environment, preventing a perfect score.

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?

There is no guidance about when to choose this tool over alternatives like FulfillmentInbound_listInboundPlans, getInboundPlan, or updateInboundPlanName. The only contextual hint is the environment statement 'Runs in your Kuudo deployment, not here,' which is not a clear decision rule about when to invoke the tool.

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