update_people_group

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

The description indicates a mutation (rename) but discloses no additional behaviors such as required permissions, side effects, or limits. For a simple rename with no annotations, this is acceptable but minimal.

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 one concise sentence that immediately states the tool's purpose. It is front-loaded and efficient, though could be slightly expanded without losing conciseness.

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 rename tool with an output schema, the description is minimally adequate. It lacks usage context and parameter details but is not severely incomplete.

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 adds no meaning beyond the schema field names and types. It does not explain that 'name' is the new name or that 'group_id' identifies the group.

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 'Rename a people group' uses a specific verb 'Rename' and resource 'people group', making the tool's purpose immediately clear. It also distinguishes from sibling tools like create_people_group and delete_people_group.

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 provides no guidance on when to use this tool versus alternatives, such as when to use list_people_groups or create_people_group. It does not mention prerequisites or exclusions.

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