Установка дополнения в кластер

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the agent knows this is a write operation. The description adds the requirement for YAML config and config_type, but does not disclose potential behaviors like failure if the addon already exists, if installation is synchronous, or permissions needed. This is adequate but not rich.

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 with no fluff. The first states the action, the second lists requirements and points to the catalog. Every sentence earns its place.

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?

The description covers the core purpose, required inputs, and a way to find valid values. There is no output schema, but the action is straightforward. Missing details like response format or idempotency notes are minor given annotations and tool simplicity.

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 coverage is 100% and each parameter has a description. The description restates required parameters and mentions the config_type enum, adding a reference to the catalog for valid type/version values, which is useful. It does not clarify whether yaml_config is always required or just for custom, but the schema marks it required.

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: 'Installs an addon into a cluster', with a specific verb (installs) and resource (addon). It distinguishes from siblings like update_k8s_addon, uninstall_k8s_addon, and list_k8s_addons by conveying the install operation specifically.

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 provides context by listing required inputs (type, version, config_type, YAML) and explicitly points to list_k8s_addon_configs as a catalog for available addons. It does not mention when not to use it or name alternatives, but the sibling list and action verb imply distinctions.

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