update_task_list

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

With no annotations, the description must carry the full behavioral disclosure burden. It only states that it updates a task list and returns a confirmation message, omitting side effects, irreversibility, error behavior, or whether fields other than title are preserved. This is insufficient 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 concise and well-structured, with a clear opening sentence followed by Args and Returns sections. The 'Required' note is redundant but not harmful. Every line serves a purpose.

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 CRUD update with all parameters described and a basic string return, the description is reasonably complete. However, it lacks context about permissions, error cases, and whether the update is partial or full, which would be expected for a mutation tool with no annotations.

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%, but the description's Args section compensates by explaining all three parameters. It clarifies that user_google_email is required, task_list_id identifies the list, and title is the new value, adding meaning beyond the raw schema.

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 'Update an existing task list' with a specific verb and resource, distinguishing it from sibling CRUD operations like create_task_list, get_task_list, and delete_task_list. The scope 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?

The description implies use for modifying an existing task list, but it does not explicitly contrast with create, get, or delete task list tools. No prerequisites or exclusions are mentioned, leaving the agent to infer when to use this tool.

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