portainer_nodes_list

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

The description implies a read-only operation via the verb 'List', but it does not explicitly state that no modifications occur or mention any side effects. Since no annotations are provided, the description carries the full burden for transparency; the lack of an explicit safety note is a minor gap.

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, containing a one-line summary and a simple Args list. Every sentence adds value, and the structure is clean and scannable.

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?

Given the simplicity of the tool (one optional parameter, no nested objects), the description is largely complete. It specifies the resource, the returned attributes, and the parameter behavior. It omits output schema details and error handling, but these are not essential for a list operation and can be inferred from the schema.

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 single parameter endpoint_id is described as 'Target endpoint ID (uses default if omitted)', providing a basic functional explanation. However, it does not explain what an endpoint is, how to obtain a valid ID, or the impact of omitting it beyond using a default. Schema coverage is 0%, so this limited description only partially compensates.

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 verb 'List' and the resource 'Swarm nodes', specifying the attributes returned (role, availability, state, resources). This is unambiguous and distinguishes the tool from other list tools in the sibling set.

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 guidance is provided on when to use this tool versus alternatives, such as portainer_docker_info or portainer_services_list. The description does not mention typical use cases or selection criteria, leaving the agent to infer from the tool name alone.

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