update_list_name

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

No annotations are present, so the description bears full responsibility for behavioral disclosure. It does not state whether the operation is idempotent, what happens if the old name does not exist, or if there are any side effects. This is a significant gap for a mutation tool.

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 relatively short and front-loaded with the action. However, it uses a mix of Spanish and English, which is slightly redundant ('Cambiar, actualizar o update'). It could be more concise by using a single language.

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 rename tool with two parameters and no output schema, the description is minimally adequate but missing key details like what the tool returns or if the operation is reversible. Given the lack of annotations, it is incomplete.

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?

With 0% schema description coverage, the description should compensate by adding meaning beyond parameter names. However, it merely restates 'OldName' and 'NewName' in a sentence, offering no additional constraints, formats, or examples.

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 identifies the action (rename/update) and resource (list name). It specifies the old name and new name parameters, making the tool's purpose immediately understandable. A slight deduction for the awkward multilingual phrasing, but it is functionally clear.

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 regarding when to use this tool versus its siblings (e.g., create_list, get_list). There is no mention of prerequisites, when not to use it, or what context is appropriate.

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