Увеличение количества нод в группе

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, covering the mutation and safety profile. The description adds that it adds worker nodes and optionally labels, but does not disclose side effects like potential cost increase or long-running provisioning, so it does not go beyond annotations.

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 two short sentences, front-loaded with the primary action, and contains no extraneous information. It is efficient and clear.

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 4 fully documented parameters, annotations indicating a non-read-only mutation, and no output schema, the description is adequate for a straightforward operation. It could mention preconditions or asynchronous behavior, but the schema and sibling tools provide enough 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?

Schema descriptions cover 100% of parameters, including count and labels. The description merely restates that a specified number of nodes are added and labels can be assigned, which is already captured in the schema, so it adds no new semantic meaning.

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 explicitly states 'Добавляет указанное количество воркер-нод в группу' (Adds the specified number of worker nodes to the group), providing a specific verb and resource. It distinguishes from the sibling tool reduce_k8s_node_group_nodes by indicating an increase rather than a decrease.

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 does not explicitly state when to use this tool vs alternatives, such as reduce_k8s_node_group_nodes, nor does it mention any exclusions or preconditions. Usage is implied by the clear purpose and the presence of a sibling operation that scales in the opposite direction.

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