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

With no annotations provided, the description carries the full burden for behavioral disclosure. It mentions the connection prerequisite but does not describe what happens when the action is performed (e.g., turning the light on/off, brightness applied), potential errors, or the nature of the response. For a control tool, this is a significant transparency gap.

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 exactly two sentences: a clear purpose statement and a critical prerequisite note. There is no redundant text or filler; every sentence earns its place. It is appropriately sized for a relatively simple tool.

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?

Given the 100% schema coverage and lack of output schema, the description provides the essential purpose and a key prerequisite. However, it does not mention expected return values, failure modes, or state changes beyond 'control'. It is adequate for basic understanding but leaves the agent to infer runtime behavior, which is a clear gap for a tool with no annotations.

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 fully documents all parameters including brightness and device_number. The description adds no parameter-specific meaning beyond the schema; its only extra context is the external connection prerequisite, which is not tied to any individual parameter. Baseline 3 is appropriate.

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 states the tool 'Control an ASCOM Alpaca cover calibrator light', which clearly identifies the verb (control) and the resource (cover calibrator light). It distinguishes from sibling tools like 'alpaca_covercalibrator_cover' by specifying 'light', though 'control' is somewhat generic without listing the specific actions (on/off) that appear in 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 prerequisite note: 'Device must be connected first using alpaca_device_connect.' This gives a clear condition for use but does not explicitly contrast with alternatives (e.g., using status tools) or specify when not to use it. Usage is implied rather than fully elaborated.

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