create_group

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

With no annotations, the description carries the full burden of disclosing behavioral implications. It states 'Create' (a write operation) but omits permission requirements, potential side effects, or prerequisites. The one-sentence description provides no additional context about what happens when a group is created.

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 a single, straightforward sentence that states exactly what the tool does with no unnecessary words. It is appropriately minimal and front-loaded.

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 complex nested parameter is fully documented in the schema, and an output schema exists, so return values are covered. However, the description lacks any context about permissions or when to use this over other group-management tools, which is minor given the clarity of the schema and sibling names.

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 has 100% coverage of the group_data property, documenting all sub-properties with descriptions and required flags. The description adds no extra parameter information, so a baseline score of 3 is appropriate since the schema does the heavy lifting.

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 creates a new group in Microsoft Graph. The verb 'create' and resource 'group' are specific, and it distinguishes from sibling update/delete and read tools. Even though there are other 'create' tools, the resource type is explicit.

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 explicit guidance on when to use this tool versus updating or deleting a group. Usage is implied by the purpose and the existence of sibling tools like update_group and delete_group, but no alternatives or exclusions are mentioned.

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