update_checklist_name

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

There are no annotations to characterize safety or side effects, so the description carries the full burden. It only states the action without disclosing behavioral traits such as whether the operation is persistent, requires specific permissions, or returns the updated checklist. For a mutation tool with zero annotation coverage, this 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 short (two sentences) and front-loaded with the action. However, the second sentence ('Use this tool to rename a checklist') is largely redundant with the first, making it slightly less efficient than ideal. Still, it is concise and well-structured.

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?

With four parameters including response-controlling fields and detailLevel, and no output schema, the description is incomplete. It does not explain what the tool returns, how to interpret the response, or how to customize it via the optional parameters. The presence of these parameters suggests a response, but the description omits any mention of it, leaving the agent under-informed.

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 documents all four parameters with descriptions, so coverage is 100%. The description adds no additional meaning beyond the schema; it only mentions 'name' in the text but does not elaborate on the fields or detailLevel parameters. Baseline of 3 applies because the schema does the heavy lifting.

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 tool's action: 'Update the name of a checklist.' It uses a specific verb (update) and resource (checklist name), and distinguishes itself from sibling tools like update_checklist by focusing solely on renaming. The second sentence reinforces the purpose without ambiguity.

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 says 'Use this tool to rename a checklist,' which is essentially a restatement of the purpose. It provides no guidance on when to prefer this over alternatives like update_checklist, nor any exclusions or prerequisites. No explicit alternatives are mentioned.

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