pause_launch

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

The description discloses the use of SIGSTOP and process suspension, implying the session is temporarily halted and can be resumed. However, it does not mention permissions, side effects (e.g., state upon resume), or any destructive behavior. Since no annotations exist, the description carries the full burden but provides only basic behavioral information.

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 concise, using a clear docstring format with Args and Returns sections. It avoids unnecessary detail but is not excessively terse. One minor issue: the Returns line is generic but acceptable.

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 has a simple interface (one parameter, no nested objects) and an output schema exists, so the description does not need to cover return values. However, the description omits any contextual information about prerequisites, errors, or post-conditions, which would help completeness.

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 schema description coverage is 100% (the parameter 'session_id' is described both in the schema and in the description's Args). The description adds no additional meaning beyond the schema, so a baseline score of 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 clearly specifies the action ('Pause a running launch session'), the mechanism ('using SIGSTOP'), and the effect ('Suspends all processes in the session's process group'). It distinguishes from sibling tools like resume_launch, stop_launch, and start_launch.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., stop_launch for termination, restart_launch for restart). The description lacks context about the appropriate scenarios for pausing.

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