Get Playdate Simulator control status

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

The description explicitly discloses that the tool may inject the control agent, which meaningfully complements the annotations by explaining the non-read-only behavior. It identifies both the side effect and the condition under which it occurs, with no contradiction.

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?

Two short sentences deliver purpose, behavior, and a side-effect warning with no filler. The key action is front-loaded and every clause earns its place.

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 description is sufficient for a low-complexity tool: it states the purpose, the conditional mutation, and relies on the output schema for return details. The exact meaning of 'selected Simulator' and 'control agent' is left implicit, but this is unlikely to block correct 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?

The schema already provides full documentation for the single optional pid parameter, so the description carries no added parameter burden. The phrase 'selected Simulator' relates to the selection context but does not add 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 names a specific action and resource: find the selected Simulator, ensure its control agent is available, and return agent status. It is clear and not a tautology, but it does not contrast with sibling tools such as playdate_inject or playdate_run.

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 explicit when-to-use guidance or mention of alternatives. The sentence 'This may inject the agent when it is absent' hints at a relevant side effect, but it does not tell the agent when to prefer this tool over playdate_inject or other siblings.

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