create_subtasks

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

With no annotations, the description carries the burden of behavioral disclosure. It does explain input structure and validation constraints (e.g., project_id must match), but it doesn't mention side effects, return values, error handling, or permissions. Basic mutation is implied but not stated. This is adequate but not rich behavioral context.

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 well-organized with an intro, ARGS section, and examples. Every sentence adds value; no filler. The format is scannable and the examples clarify the structured data needed. Length is justified by the need to document a flexible schema.

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?

Given the sparse schema and the tool's role in creating subtasks, the description is highly complete. It covers all necessary input details, constraints, and multiple usage scenarios. An output schema exists, so return-value documentation is unnecessary. The info provided is sufficient for correct selection and invocation.

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% and the schema is minimal (just a generic 'subtasks' object/array). The description fully compensates by listing every subfield with required/optional status, priority enum values, and case-insensitivity. It also provides concrete examples for single and multiple subtasks, making invocation straightforward.

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: 'Create one or more subtasks for parent tasks.' This clearly distinguishes it from sibling tools like create_tasks by specifying the parent relationship. No ambiguity.

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?

While it doesn't explicitly state alternatives or exclusions, the description clearly implies when to use this tool (when creating subtasks under an existing parent task). The detailed parameter requirements (parent_task_id, project_id) provide context for usage, but it lacks direct statements about when not to use it.

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