create_subtask

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

No annotations provided, so description carries full burden. It discloses a verification step ('verify the parent-child relationship afterwards') and includes authentication hints ('Auth: V1 + V2'). This adds behavioral context beyond the schema.

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 very short (two sentences) and includes valuable metadata (Category, Auth, Related) upfront. However, it could be more concise if parameter details were included.

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?

With 16 parameters, no output schema, and no parameter descriptions, the description is incomplete for full understanding. The core action is clear, but users lack guidance on optional fields like content, desc, priority, etc.

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 coverage is 0% (no descriptions in schema), but the description does not explain any of the 16 parameters, even critical ones like parent_id, title, or project_id. The description adds no meaning beyond the schema's field names.

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 child task and verify the parent-child relationship afterwards' uses a specific verb ('Create') and resource ('child task') and clearly distinguishes from siblings like create_task (general) and set_subtask_parent (which doesn't create).

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 includes a 'Related' section listing alternatives and a 'Category: Verified Actions' tag, hinting at when to use (for verified subtask creation). However, it does not explicitly state when not to use or compare to alternatives like create_task + set_subtask_parent.

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