Annotations already declare readOnlyHint=false (a write operation) and destructiveHint=false. The description adds no additional behavioral context, such as effect on existing clients or permissions. It does not contradict the annotations, so a baseline score of 3 is appropriate since it adds no extra value beyond the structured fields.
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 a single, front-loaded sentence with zero wasted words. It communicates the action and target resource efficiently, making it easy for an agent to parse quickly.
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 operation with two fully described parameters and an output schema, the description is sufficient. It covers the core action and resource; the schema handles parameter details and the output schema defines the return value. There is no missing critical context that would prevent 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?
The input schema has 100% description coverage; both 'id' (Folder ID from list_folders) and 'name' (New folder name) are well documented. The description 'Rename a client folder' does not add any parameter-specific meaning beyond the schema, so the baseline of 3 is correct.
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 client folder' uses a specific verb (rename) and a clear resource (client folder). It clearly distinguishes from siblings like create_folder, delete_folder, list_folders, and move_client_to_folder, making the tool's purpose unambiguous.
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 implies usage by stating the operation, but it does not explicitly contrast with alternatives. For instance, it does not say 'to create a new folder, use create_folder' or 'to move a client between folders, use move_client_to_folder.' However, the sibling names make the distinction fairly obvious, so the guidance is implied rather than explicit.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
