pin_pause

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 mutation but says nothing about whether execution halts immediately, whether state is preserved, whether the pause is synchronous, or how it interacts with pin_resume.

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 with no wasted words. It is appropriately terse for a simple no-parameter action, though the terseness contributes to the behavioral gaps rather than being a structural flaw.

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?

The tool is low-complexity (zero parameters, no output schema, no annotations), so the description does not need to explain return values. Still, it omits the state relationship with sibling tools like pin_resume and pin_stop, leaving a meaningful contextual gap for an agent coordinating a debugging session.

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 tool has zero parameters, so there is nothing for the description to clarify beyond what the schema trivially provides. Baseline 4 applies for a no-parameter tool.

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?

States a clear verb ('Pause') and resource ('the instrumented process'), so the action is unambiguous. However, it does not differentiate itself from siblings like pin_stop or pin_resume, leaving the agent to infer that this is a reversible halt distinct from termination.

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 no when-to-use guidance, prerequisites, or alternatives. It never mentions pin_resume or pin_stop, so the agent gets no explicit direction on which pause-adjacent tool to choose.

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