get_cluster_rate

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

Annotations are absent, so the description bears full burden. It does not mention behavioral traits like read-only nature or idempotency. However, the tool name 'get' implies a read operation, and for a simple retrieval, the omission is acceptable but not ideal.

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 concise: three sentences, front-loaded with purpose, then usage, then parameter. Every sentence earns its place with no redundancy.

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 is a simple one-parameter getter with no output schema, the description is complete. It explains what the tool does, when to use it, and the parameter meaning. No gaps.

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 0%, meaning the schema only provides name and type without description. The description adds 'Name of the cluster' for the single parameter, which is basic but adds clarity. With low coverage, the description compensates minimally.

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?

Clearly states 'Return the configured GPU cost rate for a cluster.' The verb 'Return' and resource 'GPU cost rate for a cluster' are specific. Distinguishes from siblings like set_cluster_rate and get_cost_estimate by mentioning them in the description.

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?

Explicitly says 'Used to verify the rate before interpreting get_cost_estimate results. To set or update the rate, use set_cluster_rate.' This provides clear when-to-use guidance and an alternative tool.

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