Stop all containers

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

The description adds a behavioral risk warning ('HIGH RISK') beyond the annotations, which only indicate non-destructive and idempotent hints. However, it does not disclose specific side effects, such as whether containers can be restarted or if the operation affects the environment's state. The risk label is useful but lacks detail.

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 extremely concise: a single sentence with a front-loaded risk tag. Every word serves a purpose, and it is efficiently scoped to convey the essential information without filler.

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 operation with one parameter, the description is adequate but lacks completeness. It does not mention the return value, whether the operation is reversible, or what happens if no containers are running. Given the absence of an output schema, a bit more context would be beneficial.

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 input schema provides 100% coverage for the single parameter 'environmentId' with description 'Environment ID'. The tool description does not add any additional meaning or constraints beyond the schema, so it meets the baseline but provides no extra value.

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 ALL running containers' and the scope 'in an environment'. It distinguishes from siblings like 'arcane_container_stop' (single container) and 'arcane_system_containers_start_all' (start all). 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 includes a '[HIGH RISK]' label implying caution, but it does not explicitly state when to use this tool versus alternatives like stopping individual containers. No exclusions or prerequisites are mentioned, leaving the agent to infer usage context on its own.

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