Update characteristic group

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

No annotations are present, so the description carries full responsibility for behavioral disclosure. It states that the tool updates a group, but it does not mention mutation effects, partial vs. full updates, permission requirements, idempotency, or what the response will contain.

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 concise and front-loaded: it states the operation in the first sentence and directs the agent to the authoritative request shape in the second. There is no filler or repeated schema information.

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 adequate for starting invocation because it names the operation and defers to get_operation_schema for exact request shape. However, it omits broader context: when to use this instead of other group operations, what happens after an update, and any behavioral caveats. It is a workable but not fully complete description.

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 covers both parameters with descriptions. The description adds meaningful guidance by telling the agent to call get_operation_schema('UpdateCharacteristicGroup') for the exact request shape, which is essential for the loosely specified 'group' object. It stops short of fully defining the nested fields itself.

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 uses a specific verb and resource: 'Update a product characteristic group.' The qualifier 'product' helps distinguish it from the similarly named update_characteristic and create_characteristic_group siblings. It does not explicitly name sibling alternatives, but the operation is clear.

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 this tool versus creating, retrieving, or listing characteristic groups. The only guidance is to call get_operation_schema for the exact request shape, which helps with request construction but not with tool selection.

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