list_ingresses

List Kubernetes Ingress objects in a namespace or all namespaces. Filter by label selector to narrow results, showing NAMESPACE, NAME, CLASS, HOSTS, ADDRESS, PORTS, and AGE.

Instructions

List Kubernetes Ingress objects with NAMESPACE, NAME, CLASS, HOSTS, ADDRESS, PORTS, and AGE.

Args: namespace: Namespace to query (empty = all namespaces). label_selector: Label selector to filter Ingresses. cluster: Named cluster to target (empty = default).

Behavior2/5

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

With no annotations provided, the description does not disclose behavioral traits such as read-only status, required permissions, or side effects. It only describes the listing action without safety or constraint details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise: one sentence for purpose followed by a structured Args block. No redundant text, and the key information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the main functionality and parameters. The existence of an output schema reduces need to describe return values. It lacks usage context and behavioral details but is adequate for a simple list operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

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 brief yet meaningful explanations for all three parameters, including default behavior (e.g., 'empty = all namespaces'). However, it lacks format constraints or examples.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it lists Kubernetes Ingress objects and explicitly lists the columns (NAMESPACE, NAME, CLASS, HOSTS, ADDRESS, PORTS, AGE), making the tool's purpose very specific and distinguishable from sibling list tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 other list tools like list_services or list_routes. No prerequisites, context, or exclusions are provided.

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