create_task

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

With no annotations, the description carries the full burden of behavioral disclosure. It states the mutation ('Create') and the return confirmation, but does not disclose auth requirements, potential errors (e.g., invalid task list), idempotency, or side effects. For a write operation, this is a notable gap.

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 well-structured docstring with a one-line purpose, Args list, and Returns. Every sentence adds value, and the format is easily parseable. No redundant or filler 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 7-parameter create tool with no schema descriptions and no annotations, the description covers all parameters and the return type. However, it lacks operational context such as authentication prerequisites or error behavior, which would be necessary for a fully self-contained tool definition. Given the output schema exists, return values are covered, but dynamic context is missing.

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 compensates with a detailed Args section. It explains each parameter's purpose, marks required vs optional, and provides format details (e.g., due as RFC 3339). This goes well beyond the raw schema, though some context like how to obtain task_list_id is missing.

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 'Create a new task in a task list' is a specific verb+resource statement. It clearly distinguishes this from sibling tools like create_task_list, list_tasks, and update_task, leaving no ambiguity about what action is performed.

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 purpose implies when to use it (creating tasks), but there is no explicit guidance on when not to use it or alternatives. It doesn't mention prerequisites like needing an existing task_list_id or authentication, which would help an agent decide between this and other tools.

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