alpaca_covercalibrator_cover

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

With no annotations, the description carries the full burden of behavioral disclosure. It only notes a connectivity prerequisite and the basic actions. It does not explain the 'halt' action, potential side effects, error conditions, or confirmation behavior for a hardware-mutating operation.

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—two sentences, front-loaded with the purpose, then a necessary prerequisite note. No filler 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 tool, it provides the key prerequisite and purpose, but lacks explanation of the 'halt' action and any return/error behavior. With no annotations or output schema, this leaves the agent with some ambiguity about invoking success or handling failures.

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 all parameters are documented in the schema. The description adds no additional parameter meaning beyond stating the open/close intent and the connection prerequisite; it does not clarify the 'halt' action or device_number semantics 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 identifies the resource (ASCOM Alpaca cover calibrator cover) and the primary actions (open or close). It distinguishes from sibling tools like alpaca_covercalibrator_status and alpaca_covercalibrator_calibrator, though it omits the 'halt' action from the schema.

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 provides a clear prerequisite (device must be connected first) but does not offer explicit guidance on when to use this tool versus alternative cover/calibrator tools or when not to use it. The connection note is useful context but does not cover alternatives.

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