subagent

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that delegation to a native engine occurs, but does not describe side effects, execution model, whether results are returned, or any environmental requirements such as an active Roblox Studio session.

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 one sentence with no filler, and the action verb appears immediately. It is efficient, though the brevity sacrifices meaningful usage and behavioral details.

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 no output schema and no annotations, the description omits important invocation context: what the delegation returns, whether execution is asynchronous, and what prerequisites exist. For a tool with an open-ended context object and a vague 'task' parameter, this is incomplete.

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 description coverage is 100%, so the schema already documents both 'task' and 'context'. The description adds no additional meaning about how to structure the task instructions or what keys the optional context object should contain, leaving the context object entirely opaque.

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 ('delegates') and names the resource ('complex sub-task', 'Roblox native subagent engine'), so an agent can clearly infer the tool's core function. It does not explicitly differentiate itself from sibling execution tools like execute_luau or batch_execute, which keeps it from a 5.

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?

There is no guidance on when to use this tool versus alternatives such as execute_luau, feature_implement, or batch_execute. The word 'complex' weakly implies a usage context, but no criteria, prerequisites, or exclusions are stated.

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