node_rename

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

The description only says 'Rename a node' and gives parameter meanings. It does not disclose effects such as whether the rename is persistent, whether references are updated, or whether an error occurs for invalid paths. Since no annotations are provided, this lack of behavioral detail is a significant gap.

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 very short and front-loaded with the main action. The parameter bullets are compact and easily parsed. It sacrifices some explanatory depth, but for a simple two-parameter tool, the structure is appropriately concise.

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?

This is a mutating operation with no annotations, no output schema, and no usage context. The description does not explain path format, whether the operation is reversible, or what happens on failure. Given the breadth of sibling node tools, more context is needed to safely invoke this tool.

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 description adds minimal meaning beyond the schema by saying path is the 'Full path of the operator' and name is the 'New name for the operator.' However, it does not explain expected path formats, name constraints, or uniqueness rules, so it only partially compensates for the schema's lack of descriptions.

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 action, 'Rename a node', and identifies the target resource, which distinguishes it clearly from siblings like node_create or node_set_flags. It lacks an explicit contrast with similar tools, but the verb and scope are 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?

No guidance is provided on when to use this tool versus alternatives, such as whether path or node identifier should be used, or when node_set_flags would be more appropriate. The description simply states the action with no usage context or exclusions.

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