stop_simulator

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

With no annotations, the description carries full burden for behavioral traits. The description states it stops a process, but does not disclose potential side effects (e.g., data loss, cleanup, permissions). For a simple action, this may suffice, but lacks depth.

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, short sentence of 5 words. It is front-loaded and contains no unnecessary words. Perfectly concise.

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, straightforward action), the description is mostly complete. However, it lacks information about return values or confirmation of success. Still sufficient for its low complexity.

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 zero parameters, so baseline for '0 params' is 4. The description does not need to add parameter meaning as none exist. Schema coverage is 100% vacuously.

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 'Stop the PLC simulator process' uses a specific verb ('stop') and a clear resource ('PLC simulator process'), distinguishing it from siblings like 'start_simulator'. It is unambiguous and precise.

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?

While no explicit when-to-use or exclusions are stated, the context is clear: this tool is for stopping the simulator. The sibling tool 'start_simulator' implies the opposite action, so usage context is inferable. A slight improvement would be to explicitly contrast with start_simulator.

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