tasks_tasklists_insert

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

The description matches the annotations: readOnlyHint=false, idempotentHint=false, destructiveHint=false. It does not add behavioral context beyond what the annotations already communicate, such as return behavior or side effects, but it also does not contradict them.

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 clear sentence with no filler or redundant wording. It is appropriately sized for a one-parameter creation tool and front-loads the core action immediately.

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 create operation with one required parameter and complete schema coverage, the description is nearly sufficient for an agent to invoke the tool. The main missing piece is the return value, especially since there is no output schema, but this is not critical for a correct invocation.

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 100% and the only parameter, 'title', is documented in the schema as 'Task list title'. The description adds no additional parameter meaning, which is acceptable because the schema already fully covers the 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?

The description uses a specific verb ('Create') and a specific resource ('task list'), making the operation unambiguous. It clearly distinguishes itself from sibling tools like tasks_tasklists_update, tasks_tasklists_get, and tasks_tasklists_delete by stating it creates a new list.

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 usage context is implied by the verb 'create' and the resource name, so an agent can infer it is the right tool when a new task list is needed. However, it provides no explicit guidance about when NOT to use it or which sibling alternative to choose in related cases.

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