add_group_owner

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

With no annotations, the description carries the full burden of behavioral disclosure. It implies a mutation ('add') but fails to mention idempotency, permission requirements, error handling, or effect of adding an existing owner. Minimal additional value beyond the tool name.

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?

A single, direct sentence that is perfectly concise and front-loaded. Every word contributes to the meaning, with no irrelevant details.

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 tool is simple, with an output schema and well-documented parameters, making the description functionally adequate. However, it lacks usage guidance and behavioral nuance, such as the distinction from add_group_member or whether admin privileges are required.

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 coverage is 100% with clear descriptions for group_id and owner_id, so the baseline is 3. The description adds no extra parameter meaning, but the schema already adequately explains the 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 'Add an owner to a group' uses a specific verb and resource, clearly stating the action and target. It inherently distinguishes from sibling add_group_member by specifying 'owner' rather than 'member'.

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?

No guidance is provided on when to use this tool versus alternatives like add_group_member, or any prerequisites or exclusions. The description gives no usage context.

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