rename_list

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

Annotations already indicate destructive and read-only behavior, but the description adds no additional behavioral context beyond the literal rename action. It does not mention whether the list id stays stable, whether tasks are affected, or whether the rename is reversible, so the description carries little weight beyond the annotations.

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, concise sentence with no filler or repetition. It delivers the core instruction upfront without wasting tokens.

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 two-parameter mutation, the description plus schema is reasonably sufficient to attempt a call. However, the missing usage guidance and lack of new_name semantics create noticeable gaps, even though no output schema is present to explain return values.

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 only 50%, and the description does not compensate. The 'list' parameter is documented in the schema, but 'new_name' has no description, and the tool description adds no constraints like uniqueness, length limits, or formatting expectations.

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 uses a specific verb ('Rename') and resource ('a To Do list'), making the operation immediately clear. It is also distinct from the sibling tools like create_list, delete_list, and list_lists, so an agent can tell them apart without opening the schema.

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 gives no guidance about when to use this tool instead of alternatives, nor any prerequisites such as the list needing to already exist. There is no mention of when renaming is appropriate or what happens if the new name conflicts with an existing list.

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