update_resource_group

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Update' signals mutation but gives no details about partial-update behavior, null-clearing semantics, side effects, or expected response. The schema shows null-clearing behavior, but the description itself reveals almost nothing.

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 front-loaded, but it is under-specified rather than concise. For a tool with a complex nested request body and two required parameters, one generic sentence omits essential 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?

Even though an output schema exists and the input schema contains rich field descriptions, the description itself leaves out the high-level context an agent needs: what an update changes, how null values behave, and how this operation fits with sibling resource-group tools. The definition is therefore incomplete for a mutating tool of this complexity.

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%, so the description must compensate for missing parameter documentation. It does not mention group_id, the required body object, the required name field, or any of the updatable fields. An agent cannot learn parameter semantics from the description at all.

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 states the basic action and resource: 'Update a resource group.' However, it says nothing about what aspects of the group can be updated, so it is only slightly more informative than the tool name and does not distinguish update semantics from related resource-group operations.

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 on when to use this tool versus create_resource_group, delete_resource_group, add_resource_group_member, or remove_resource_group_member. The update action is inferable from the name, but the description gives no conditions, prerequisites, or exclusions.

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