karea_create_subtask

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

No annotations are provided, so the description carries the full burden. It only states the purpose and parent identification, but does not disclose behavioral traits such as side effects (e.g., what happens if parent doesn't exist), idempotency, error handling, or any prerequisites. The reference to karea_create_task shifts the responsibility without detailing behavior.

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 extremely concise with two sentences. The first states the core purpose, and the second adds essential context about parent identification and parameter reference. No unnecessary words.

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 tool has 12 parameters, no output schema, and no annotations, the description is inadequate. It does not explain return values, error states, or how the subtask relates to the parent. The reliance on another tool's documentation (karea_create_task) reduces 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 coverage is 100%, so baseline is 3. The description adds minimal new meaning: it explains parent identification options and notes that the category defaults to the parent's. The rest of the parameters are not elaborated beyond what the schema already provides.

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's purpose: 'Create a subtask under a parent task.' It specifies the verb (create), resource (subtask), and context (under a parent task). The parent identification options are given, and the reference to karea_create_task helps distinguish from top-level task creation.

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 explicitly says when to use the tool (to create a subtask) and provides details on how to identify the parent. However, it does not explicitly state when not to use it or mention alternatives beyond referencing karea_create_task for parameters.

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