create_task

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

With no annotations, the description must carry behavioral disclosure. It states the primary side effect (creation) and the root default for parent_id, which is useful. But it does not describe return values, whether the operation is idempotent, or behavior on invalid parent_id, leaving some important runtime behavior undisclosed.

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 opens with a one-sentence purpose and follows with a compact, scannable Args list. Every line carries essential information; there is no filler.

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 adequately covers parameters and creation context, but with no output schema it omits the return value or created task identifier, and it gives no error or validation details. This is a moderate gap for an agent that may need to chain the result into subsequent calls.

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?

The input schema has 0% description coverage, so the description compensates by explaining all five parameters: description, dod, deadline (with format hint), assignee, and parent_id (with default behavior). This fully maps parameter names to their meanings.

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 and resource: 'Creates a new task (or subtask) in the single task tree.' It clearly indicates the creation action and the parent/root relationship, and it is distinct from siblings like update_task, delete_task, and list_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 verb 'Creates' gives clear context for when the tool is appropriate, and the optional parent_id clarifies the subtask vs root scenario. However, it does not explicitly mention alternatives or exclusion criteria beyond what the sibling names imply.

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