pause_job

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action ('Pause') and technical effects ('feed hold + pause sender'), but does not describe what happens after pausing (e.g., whether the job can be resumed, if machine state is preserved, or any side effects like spindle stopping). For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding the tool's behavior.

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 a single, efficient sentence that front-loads the core action ('Pause the current job') and adds clarifying technical detail ('feed hold + pause sender') without redundancy. Every word earns its place, making it highly concise and well-structured for quick comprehension.

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 complexity (a mutation with no annotations or output schema), the description is minimally adequate. It explains what the tool does but lacks details on behavioral outcomes, error conditions, or interaction with sibling tools like 'resume_job'. Without annotations or output schema, more context would be helpful, but it meets the basic threshold for understanding the tool's primary function.

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 input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description does not mention any parameters, which is appropriate. It earns a baseline score of 4 because it avoids unnecessary parameter details while clearly describing the tool's action without relying on parameter context.

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 states the specific action ('Pause') and target resource ('the current job'), with additional technical detail ('feed hold + pause sender') that distinguishes it from sibling tools like 'feed_hold' (which might only pause motion) or 'stop_job' (which might terminate the job). This precise verb+resource combination makes the purpose unambiguous.

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 context by specifying 'the current job', suggesting it should be used when a job is actively running. However, it does not explicitly state when to use this tool versus alternatives like 'feed_hold' or 'stop_job', nor does it mention prerequisites (e.g., job must be running) or exclusions. The context is clear but lacks explicit comparative guidance.

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