create_task

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It does add useful context, such as list_id determining the workspace automatically, but it does not disclose return values, error behavior, permission requirements, or the fact that the task will be immediately visible. For a mutation tool, this leaves notable gaps.

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 compact and front-loaded with the core action, then expands into conditional prerequisite guidance. Every sentence earns its place, and there is no redundant or filler content. It is appropriately sized for a tool with this many optional parameters.

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?

The description is helpful for the main workflows but lacks output and error information. Since there is no output schema, an agent does not know what the tool returns on success (e.g., a created task object with an ID). Given the tool's complexity and absence of annotations, a bit more behavioral context would be needed for full completeness.

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%, so the baseline is 3. The description goes beyond the schema by explaining how list_id determines the workspace, and by recommending specific lookup tools (list_members, list_custom_fields) for assignee_ids and custom_fields. This adds semantic relationships that the schema alone does not convey.

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 states a specific action, 'Create a new task in a list', with a clear resource and scope. It is immediately distinguishable from sibling tools like get_task, update_task, and delete_task because it is the only creation action for tasks.

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 provides explicit when-to-use guidance and prerequisite workflows: it tells the agent to call list_lists if given a list name, list_statuses for status options, list_members for assignee IDs, and list_custom_fields for custom field IDs. This clearly routes the agent through the correct sequence before invoking the tool.

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