FulfillmentOutbound_getFeatureInventory

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

There are no annotations, so the description must carry the full behavioral burden. It discloses a deployment caveat, but it does not state whether the operation is read-only, whether it has side effects, what authorization is required, or what the response shape is. The verb 'Returns' implies a read operation, but this is not made explicit.

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 core sentence is concise and front-loaded, but 'Catalog entry.' adds little value and 'not here' is vague. The description is short enough to be readable, yet it contains filler that could have been replaced with more useful operational detail.

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 no output schema and no annotations, the description is under-specified. It omits how to specify the feature, what feature identifiers are valid, whether getFeatures should be called first, and what the returned inventory item list contains. The deployment caveat is useful but the operational context remains incomplete.

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 with additionalProperties allowed, but the description says 'the fulfillment feature you specify' without naming a parameter, format, or valid values. This introduces a phantom parameter that the agent cannot determine from the schema or description, making correct invocation ambiguous despite zero declared parameters.

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 names a clear verb ('Returns') and resource ('list of inventory items') and specifies the selection criterion ('eligible for the fulfillment feature you specify'). It is distinguishable from sibling tools like getFeatures or getFeatureSKU by focusing on inventory eligibility, though the phrase 'Catalog entry' and the deployment caveat add some noise.

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 provides no guidance on when to use this tool versus alternatives such as FulfillmentOutbound_getFeatures or FulfillmentOutbound_getFeatureSKU. It mentions deployment context ('Runs in your Kuudo deployment, not here') but not use cases, prerequisites, or exclusions.

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