playtest_control

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 behavior disclosure. It only states that the tool controls playtest mode and mentions proxy routing; it does not disclose side effects, whether actions mutate state, whether Studio must already be in playtest mode, or how errors behave. The description is a functional summary rather than a behavioral disclosure.

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 a single, front-loaded sentence with no filler. It conveys the operation, the environment, the available modes, and the routing context efficiently. Every phrase contributes to understanding the tool's basic purpose.

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?

The tool has four optional parameters, including three overlapping ways to express actions (mode, action, is_start), and no annotations or output schema. The description does not clarify parameter precedence, whether studio_id is needed, or how this tool relates to overlapping siblings. This is insufficient guidance for an agent to reliably invoke the tool correctly.

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 input schema fully documents each parameter, including enums for mode and action. The description adds no additional parameter-level meaning, but the schema is sufficient. Baseline 3 is appropriate because the description does not need to compensate for schema gaps.

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 a specific action—controlling playtest simulation mode in Roblox Studio—and enumerates the supported operations (Start / Stop / Pause / Resume). It is not a tautology and gives a concrete resource. However, it does not distinguish this tool from the sibling start_stop_play, which appears to overlap in purpose.

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 gives no guidance on when to use this tool versus alternatives like start_stop_play or playtest_run_scenario. It does not state prerequisites, exclusions, or which sibling should be selected under which conditions. The phrase 'Control playtest simulation mode' implies a use case but leaves selection entirely to the agent.

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