Create Swarm service

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

Beyond the 'create' verb, the description provides no behavioral details. Annotations are all false, but the description does not add context about prerequisites or side effects. For a creation tool, it should at least hint at potential resource conflicts or constraints.

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, focused sentence that immediately conveys the tool's purpose. It is concise without any fluff.

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?

Despite the tool having 8 parameters including nested objects and no output schema, the description only states the primary action. It does not provide guidance on required swarm state, error scenarios, or return format. This is insufficient for an AI agent to invoke the tool correctly without additional context.

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?

With 100% schema description coverage, the schema does a good job explaining parameters. The tool description does not add any additional parameter semantics. Hence a baseline score of 3.

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 (create) and the resource (Docker Swarm service). It differentiates from sibling tools such as arcane_swarm_update_service and arcane_swarm_delete_service.

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?

No usage guidelines are provided. There is no mention of when to use this tool over arcane_swarm_update_service or arcane_swarm_scale_service, nor any prerequisites or caveats.

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