rename_element

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

With no annotations provided, the description carries the full burden. It only mentions that the rename affects the testname in the .jmx, giving a small hint, but it does not disclose side effects, reversibility, permission requirements, or what happens to existing references. For a mutation tool, this is insufficient.

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, direct sentence that front-loads the action. It is appropriately concise with no filler, though its brevity comes at the cost of missing essential context, which slightly reduces the score from a perfect 5.

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 has 3 required parameters, no annotations, no output schema, and a 0% schema description coverage, the description is severely inadequate. It fails to explain any parameter semantics, usage context, or behavioral consequences, making it nearly impossible for an agent to call it correctly without external knowledge.

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 compensate for explaining the three required parameters (planId, nodeId, name). It does not mention any of them, leaving the agent to guess which parameter is the new name and what the others mean. This is a critical gap.

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 action (rename) and the resource (element), and adds specific context that it affects the testname in the generated .jmx. It distinguishes from siblings like update_element or remove_element by focusing on the rename operation, though it doesn't explicitly name alternatives.

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: if you need to rename an element, use this tool. However, it provides no explicit conditions, prerequisites, or comparisons with sibling tools like update_element, leaving the agent to infer when this is the right choice.

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