stop_execution

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

With no annotations, the description carries the full burden of disclosing behavior. It does reveal the internal action (SIGTERM), but omits consequences such as whether the stop is graceful, what happens if the execution is already stopped, or whether any cleanup occurs. It also does not mention potential side effects or error states. The provided detail is useful but incomplete.

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, tight sentence with no filler. It front-loads the primary action and includes the key behavioral detail (SIGTERM) without redundancy. Every word contributes meaning.

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 simple with one parameter and no output schema. The description covers the core action and mechanism, but given the absence of annotations and output schema, it could state what the caller should expect (e.g., a success status or error if execution not found). It also omits edge cases like calling on an already stopped execution. These gaps are moderate for a low-complexity tool.

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 description coverage is 0%, so the description must compensate. It mentions 'running test execution' which loosely implies the executionId identifies that execution, but it does not explicitly explain the parameter. For a single unambiguous identifier, this minimal inference is acceptable, but the description adds no explicit clarification beyond the schema's bare type.

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 action ('Stop a running test execution') and the specific mechanism ('sends SIGTERM to the JMeter process'). It distinguishes itself from siblings like execute_test_plan (which starts) and get_execution_status (which reports status) by focusing on termination. The verb and resource are specific and 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 it should be used on a running execution but does not explicitly state when to use it versus alternatives. It lacks exclusions, such as 'only use if execution is in a running state' or 'for status checks, use get_execution_status instead'. No guidance is provided on prerequisite conditions or alternatives.

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