todo_update_list

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

With no annotations, the description carries the full behavioral burden. It implies a mutation but says nothing about permissions, whether the rename is reversible, what happens to existing tasks, or what error occurs for an invalid list_id.

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?

A single short sentence with no filler, so it is concise, but the brevity reflects under-specification rather than economical phrasing of useful content.

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 two-required-parameter mutation tool with no annotations, no output schema, and zero schema descriptions, the description leaves too much unspecified: target identification, new-value semantics, and failure modes are all absent.

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 coverage is 0%, so the description must compensate and does not. 'Rename' weakly implies display_name is the new name, but list_id is never explained (e.g., that it identifies the target list) and no format or constraints are given for either parameter.

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?

States a specific verb (Rename) and resource (To Do list), which clearly separates it from todo_create_list, todo_delete_list, and the task-level siblings. It does not explicitly say it is the only list-mutation-other-than-delete tool, but the verb+resource is unambiguous.

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 on when to use this versus todo_create_list or todo_delete_list, and no prerequisites such as needing an existing list_id. The agent must infer everything from the name 'update'.

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