list-fleet-clusters

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

No annotations exist, so the description must carry behavioral disclosure. It mentions the returned data (agent versions, node counts, enabled products) but does not explicitly state that the operation is read-only, safe, or list any required permissions. The pagination behavior is implied via parameters but not described. Overall, adequate for a simple list operation but lacks explicit safety or side-effect information.

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 a single, front-loaded sentence that efficiently conveys the tool's purpose. No extraneous words, and it directly states the action and the specific details returned.

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 tool has four parameters (all optional with defaults) and no output schema. The description covers the returned information but does not elaborate on response structure, error cases, or limitations. For a simple list tool, it is moderately complete but could provide more context about the expected output format.

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 fully describes all four parameters (pageNumber, pageSize, filter, tags) with 100% coverage. The description adds no additional meaning beyond the schema, so the baseline score of 3 is appropriate.

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 it lists Kubernetes clusters with specific attributes (agent versions, node counts, enabled products). It uses the verb 'List' and the resource 'Kubernetes clusters', distinguishing it from sibling list tools like list-fleet-agents.

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 vs alternatives. Among many list siblings, there is no comparison or context for appropriate use. The description does not mention any prerequisites or exclusions.

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