get_cluster_health

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

No annotations are provided, so the description carries full responsibility. It states that the tool returns health info but does not disclose any behavioral traits such as side effects, authentication requirements, rate limits, or that it is a read-only operation. The presence of an output schema is not mentioned.

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 extremely concise, just two sentences plus a parameter docstring. The main purpose is front-loaded. No superfluous content.

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 simple inputs (one optional parameter) and the presence of an output schema, the description is adequate but minimal. It does not explain what the health information contains (e.g., status color, number of nodes). Could be more complete with a brief description of the output.

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 schema has 0% description coverage, but the description adds clear semantics for the 'cluster' parameter: it is optional, and omitting it uses a default cluster. This goes beyond the schema's type/default. However, it does not explain what 'default cluster' means or how to specify it.

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 tool returns basic health information about the cluster. The verb 'returns' and resource 'health of the cluster' are specific. However, it doesn't elaborate on what 'basic information' includes, leaving some ambiguity. The sibling 'get_cluster_stats' likely provides more detail, but this is not explicitly stated.

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?

No guidance is provided on when to use this tool versus alternatives like 'get_cluster_stats'. The description does not mention prerequisites, limitations, or typical use cases. The agent must infer from the name and sibling list.

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