update_structure_group_name

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

The description discloses that this mutates the name of an existing group, but the annotations are all false and provide no safety context. It does not say whether group members are preserved, whether new_name must be unique, or what happens if the old name does not exist, which would be useful for a mutating operation.

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 compact and front-loaded, with a one-line purpose statement followed by a minimal Args list. Every element serves a purpose and there is no wasted text.

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 low-complexity rename tool with two required string parameters and no output schema, the description covers purpose, operand, and parameter semantics. It could add uniqueness or error behavior, but nothing essential is missing for correct invocation.

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%, so the description must carry parameter meaning; the Args section does this by distinguishing 'Current structure group name' from 'New structure group name'. For two simple string parameters, this is sufficient and adds meaning beyond the bare schema.

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 states a specific verb ('Rename') and resource ('existing structure group'), making it clearly distinct from sibling tools like create_structure_group, remove_structure_group, and add_to_structure_group. The bilingual wording adds no ambiguity and directly conveys what the tool does.

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 phrase 'existing structure group' clearly positions this tool as operating on an already-created group rather than creating or removing one. It does not name alternative tools or give explicit when-not conditions, so it stops short of a 5.

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