nina_focuser_stop

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

No annotations are provided. The description states 'Immediately stop' but does not disclose behavioral details such as whether the focuser position is retained, if it is safe to resume, or any error conditions. The description is adequate but lacks depth beyond the obvious.

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?

A single, front-loaded sentence that directly conveys the action with no extraneous words.

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 tool's simplicity (no parameters, no output schema, no annotations), the description sufficiently covers the purpose and action. It could mention return behavior but is not necessary for a basic stop command.

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?

There are no parameters; schema coverage is 100%. Per guidelines, baseline is 4 for zero parameters. The description does not need to add parameter information.

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 a specific verb 'stop' and resource 'focuser movement', clearly distinguishing from sibling tools like nina_focuser_move (initiates movement) and nina_focuser_info (queries state).

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 implies usage when focuser is moving and needs to be aborted, but does not explicitly state when not to use or mention alternatives. The context is clear given the sibling tools.

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