repl_kill

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

With no annotations present, the description carries the burden of behavioral disclosure. It adds meaningful detail beyond the name by specifying the signal sequence 'SIGTERM, then SIGKILL', which communicates a graceful termination attempt followed by a forced kill. It does not mention irreversibility or side effects, but the mechanism is usefully transparent.

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, front-loaded sentence with no wasted words. It delivers the core action and key behavioral detail in a compact, immediately scannable format.

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?

For a simple one-parameter tool with no output schema, the description is reasonably complete: it names the action and the termination mechanism. It is slightly limited by lacking parameter clarification and usage guidance, but those gaps are less critical given the minimal interface.

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?

Schema coverage is 0% and the description does not explain the 'id' parameter at all, even though it is required. The connection between 'id' and the REPL session being terminated is implicitly understandable from context, but the description adds no explicit semantic value beyond the raw schema.

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 ('Terminate') and clearly identifies the resource ('REPL session'), making the tool's action unambiguous. It also distinguishes itself from sibling REPL tools like repl_spawn, repl_send, and repl_list by focusing on 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 implies when to use the tool: when a REPL session should be ended. However, it provides no explicit guidance about when not to use it, no alternatives, and no mention of prerequisites such as the session being active or listed via repl_list.

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