mixer_group_rename

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

With no annotations provided, the description must disclose behavioral traits. It only says 'Rename a mixer group,' implying a mutation but not stating any side effects, permissions required, reversibility, or impact on references. This is insufficient for a tool that modifies state.

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 concise: a single sentence for purpose and two lines for parameters. It is well-structured, front-loaded with the main action, and contains no filler words. Every sentence earns its place.

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?

Given the tool is a simple rename operation but still a mutation with no annotations and no output schema, the description is incomplete. It lacks alternative guidance, behavioral caveats, and any note about what happens after the rename. It is a minimal viable description but falls short for a complete contextual picture.

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 schema has zero description coverage, so the description must explain parameters. It does: 'target: Group path or {guid}' and 'name: New name.' This provides essential meaning beyond the schema, but it lacks detail on acceptable formats or constraints, so it only partially compensates.

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's action: 'Rename a mixer group.' It uses a specific verb and resource, and it is distinct from sibling tools like mixer_group_create, mixer_group_delete, and mixer_group_info, all of which have different purposes.

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 on when to use this tool versus alternatives. The description does not mention any prerequisites, restrictions, or situations where another tool might be more appropriate. It merely states the action without contextual direction.

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