create_subtask

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

With no annotations, the description adds value by mentioning reward capabilities and required parent identifiers. However, it does not disclose behavioral traits like error handling, authentication needs, or what happens if the parent task does not exist, leaving 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 concise with three sentences, front-loading the main action. Every sentence adds value without redundancy.

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 tool with 13 parameters and no output schema, the description covers the core purpose and identifies key parameters like parent identifiers and rewards. However, it omits return value details and error handling, which would be helpful for 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 descriptions cover all parameters (100%), so the description adds limited meaning beyond grouping reward parameters. It reinforces the need for parent identifiers but does not provide new semantic detail beyond the schema.

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 clearly states the tool creates a subtask for an existing task, distinguishing it from siblings like create_task and edit_subtask. It specifies the verb 'create', the resource 'subtask', and the context of a parent task.

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 indicates that at least one parent identifier is required and that subtasks can have rewards, providing clear context. However, it lacks explicit exclusions or when-not-to-use guidance, such as when to prefer create_task or edit_subtask.

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