alpaca_camera_cooler

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It usefully notes the connection prerequisite, but it doesn't state the effect of the operation (e.g., turning the cooler on/off, setting temperature) or potential failure modes. The verb 'control' combined with schema parameter hints provides some transparency, but not full.

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 only two sentences, front-loaded with the core purpose and immediately followed by a necessary prerequisite. There is zero wasted text or redundancy.

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?

For a simple setter tool with comprehensive parameter descriptions and no output schema, the description covers the essential purpose and prerequisite. It could add that the operation is a direct command with no return value detail, but it's complete enough for an agent to 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 baseline is 3. The description adds no parameter-specific details beyond what the schema already provides; it only mentions the prerequisite. This makes it adequate but not enhanced.

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 the specific verb 'control' and resource 'cooler on an ASCOM Alpaca camera,' clearly identifying the tool's purpose. It distinguishes itself from sibling tools because no other tool targets the camera cooler.

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 an explicit prerequisite: the device must be connected first via alpaca_device_connect. This helps the agent know the correct call order. It doesn't mention alternatives or when-not to use it, but the context is clear.

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