get_cluster_nodes

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

With no annotations provided, the description must convey that this is a read-only operation; 'Get' implies this, but it doesn't disclose response format, filtering behavior, or error conditions. It adds minimal behavioral context beyond the tool name.

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?

A single, direct sentence that leads with the verb and specifies the target resource. No unnecessary words or repetition, making it highly 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 tool's simple read-only nature, fully documented parameters, and no output schema, the description adequately identifies the purpose and resource. It could mention that nodes are returned as a list, but the overall scope is clear and complete enough for a tool of this complexity.

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 input schema has 100% coverage with descriptions for all four parameters, so the schema already carries the semantic weight. The description does not add meaning beyond identifying that nodes are fetched for a cluster; it doesn't clarify parameter relationships or provide examples.

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 uses a specific verb 'Get' and resource 'nodes' with a clear qualifier 'for a specific compute cluster'. It distinctly differentiates from sibling tools like list_clusters, which enumerate clusters rather than their nodes.

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 implies usage when you need nodes for a particular cluster, but provides no explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites like verifying the cluster exists via list_clusters. There are no exclusions or alternative tool references.

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