Stop SpriteLoom service

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

The annotations already declare idempotent=true, destructive=false, and readOnly=false, so the safety profile is largely covered. The description adds useful behavioral context about the shared service and automatic idle timeout, though it does not state what happens to in-flight generation work.

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?

Two sentences, front-loaded with the action and followed by the relevant shared-service context. There is no wasted text.

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 zero-parameter service-control tool with rich annotations, the description is nearly complete. The only meaningful gap is whether stopping interrupts active sprite-generation requests.

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 tool has zero parameters, so there are no parameter semantics to explain. The empty schema is sufficient, and baseline credit applies.

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 states a specific verb and resource: 'Explicitly stop the shared headless SpriteLoom service.' It also clarifies scope by noting that generation tools share the service, which distinguishes this control action from the generation siblings.

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?

It gives clear usage context by contrasting explicit stopping with the default ten-minute idle shutdown. However, it does not name a specific alternative sibling such as status or explain situations where stopping would be inappropriate.

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