list_events

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

The readOnlyHint annotation already communicates that this is a safe read operation, so the description's added value is limited to stating the event categories included and the sort order. It does not contradict the annotations, but it also does not disclose potential limits, pagination, or more detailed runtime behavior.

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 that front-loads the key action and resource, then adds the two most important qualifiers: event types and ordering. There is no filler or redundant phrasing.

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 core behavior is stated and an output schema is present, so return values need no explanation. However, the description leaves 'recent' ambiguous relative to the hours parameter and does not clarify that namespace filtering is optional, creating a small but real gap for an agent planning the invocation.

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 description coverage is 0%, so the description carries the burden of explaining parameters. It only hints at the time window with the word 'recent,' leaving hours and the meaning of cluster and namespace mostly to inference from their names and schema defaults.

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 and resource: it lists Kubernetes events, and it adds meaningful scope by specifying that both warning and normal events are returned, newest first. This clearly distinguishes it from sibling list tools, none of which target Kubernetes events.

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 does not say when to prefer this tool over alternatives, nor does it mention any prerequisites or exclusions. The purpose implies use when Kubernetes events are needed, but there is no explicit usage guidance beyond the bare description.

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