ako_clusters

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

Annotations already declare readOnlyHint and idempotentHint, indicating a safe read operation. The description adds that it returns version and status fields, providing minor behavioral context beyond annotations. No destructive or unexpected behaviors are implied.

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 concise sentence with the '[READ]' prefix. Every word serves a purpose: identifying the resource (K8s clusters with AKO), the data returned (version, status), and the operation type (list). No unnecessary information.

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 that the tool has no parameters, annotations provide safety cues, and an output schema likely details the return structure, the description is sufficient for an agent to understand what the tool does. It is complete for a simple list operation without additional 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?

There are no parameters in the input schema, and schema description coverage is 100%. The description adds that it lists 'all' clusters, implying no filtering, which is a small additional semantic. With no params, the description does not need to add much, but it confirms the scope.

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 K8s clusters with AKO deployed, including version and status. The '[READ]' prefix helps categorize it. However, it does not explicitly differentiate from sibling tools like 'ako_cluster_overview' that might also list clusters but with different detail.

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 no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions despite having numerous sibling tools. The agent is left to infer usage from the name alone.

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