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

The annotations already indicate a non-read-only, destructive operation, and the description does not contradict this. It provides no additional behavioral context beyond 'rename,' such as side effects or irreversibility, but with annotations present, the bar is lower and the description is consistent.

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: one sentence for purpose and a brief args list. Every word is functional, and the most important information is front-loaded.

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 tool, the description is sufficient: it states the operation, covers both parameters, and the output schema (which exists) handles return values. It lacks additional context like error conditions, but the annotations provide the safety profile.

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%, but the 'Args' section compensates by explaining node_id (with example format) and name (new name). This adds meaning beyond the bare schema, covering both parameters concisely and clearly.

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 says 'Rename a node.' This is a specific verb and resource, clearly distinguishing it from sibling tools like create_node, delete_node, and update_project. It also provides the node_id format example, reinforcing the tool's identity.

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: use when you want to rename an existing node. However, it does not explicitly mention when not to use it or provide alternatives, making the guidance implicit rather than explicit.

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