aap_update_inventory

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

Annotations already indicate readOnlyHint=false and destructiveHint=false, and the description adds the PATCH method and return format (JSON with updated id/name). However, it does not clarify how null fields are handled or whether permissions are required, leaving some behavioral ambiguity.

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 compact and front-loaded, with a clear one-line summary followed by concise Args/Returns sections. No redundant information is present.

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 simple CRUD update with annotations and an output schema, this is minimally adequate. However, it omits important context about optional field semantics, especially how to indicate 'do not update' versus 'clear this field,' and the nature of the 'variables' field is left unexplained.

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?

Schema description coverage is 0%, and the description only refers generically to 'Fields to update.' It does not explain that inventory_id is required, that fields like variables or description are optional, or what values such fields accept. This forces the agent to rely on inference from names and types alone.

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 clearly states the tool updates an existing AAP inventory using PATCH, which distinguishes it from sibling tools like delete_inventory or create_inventory. The verb and resource are specific and unambiguous.

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 implies use when modifying an existing inventory, but it does not explicitly mention alternatives or state when not to use this tool. The word 'existing' provides limited guidance, but no direct comparison to sibling tools is given.

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