set_group_name

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. It only says 'Set group name' and does not mention whether the operation requires special permissions, whether it is reversible, what happens if the group name is invalid, or what the response looks like. The mutation is implied but not elaborated.

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 extremely short and front-loaded, which is efficient, but it is under-specified rather than concise. It earns its place as a minimal label but does not provide enough substance for an agent to use it confidently.

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 mutation tool with no annotations and no output schema, the description is incomplete. It does not explain return values, error conditions, permission requirements, or side effects. The two parameters are documented in the schema, but the behavioral context is missing.

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 100%, so the schema already documents both parameters (group_id and group_name). The description adds no extra meaning beyond the schema, but the baseline of 3 applies because the schema fully covers parameter semantics.

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 'Set group name' states a clear verb and resource, so an agent can tell it performs a rename operation on a group. However, it does not distinguish it from sibling tools like set_group_card or set_group_special_title, which also modify group-related attributes. The name and description are nearly identical, adding little beyond the tool name itself.

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 given about when to use this tool versus alternatives. There is no mention of prerequisites (e.g., admin permissions), no exclusions, and no reference to sibling tools. The description only restates the function name, leaving the agent to infer usage context.

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