node_remove

Destructive

Remove a node from a Docker swarm. Force is required for active nodes that have not been drained.

Instructions

Remove a node from the swarm.

A node should normally be drained (node_update with Availability "drain") and have left the swarm first, so its tasks reschedule cleanly. Removing an active/reachable node requires force=True.

args: id_or_name - The node id or name to remove force - Force removal of an active/reachable node returns: bool - True after the node is removed

Behavior4/5

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

Annotations already indicate this is destructive (destructiveHint=true). The description adds valuable behavioral context: the need to drain first, the force flag's effect on active nodes, and the boolean return value. It could mention error behavior or permissions, but the key behaviors are disclosed beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact and well-structured: purpose statement, usage/context note, args list, and return type. Every sentence earns its place with no redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 2-parameter tool with an output schema, the description is sufficiently complete. It covers the normal workflow, the force exception, and the return value. It omits error scenarios (e.g., node not found) but these are not critical for basic usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the full burden for parameter meaning. It clearly explains id_or_name (node id or name to remove) and force (force removal of active/reachable node), adding significant value beyond the bare schema types.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with 'Remove a node from the swarm', which is a specific verb+resource statement that clearly distinguishes this from sibling tools like node_inspect, node_list, and node_update. The purpose is immediately unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit when-to-use guidance: it instructs to drain the node with node_update and have it leave before removal, and explains that force=True is required for active/reachable nodes. This is excellent context for selecting the correct approach and references the relevant sibling tool.

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