K8S Posture

k8s_posture

Assess Kubernetes cluster security posture using Kubescape, with human approval required for execution.

Instructions

[AGGRESSIVE — requires human approval] Assess Kubernetes posture with Kubescape.

Kubescape ships its own MCP server. If you are doing significant Kubernetes work, connect that directly alongside Cordon rather than routing everything through this wrapper — but vet it first, like any third-party MCP server.

A3.9/5.0
Behavior4/5

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

Description discloses that the tool is aggressive, requires human approval, and is a wrapper around Kubescape. It does not detail side effects or rate limits, but the annotations are sparse and the description adds meaningful behavioral context without contradiction.

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 compact and front-loaded: it starts with the risk warning, states the purpose, then provides alternative usage guidance. No unnecessary words or redundant detail.

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

Completeness2/5

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

The description gives enough high-level context to know when to use the tool, but omits critical parameter meaning. Given the sparse schema, users would likely be uncertain about what 'context' and 'framework' should contain, making the description incomplete for actual invocation.

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

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Neither the description nor the schema explains the 'context' or 'framework' parameters. Schema coverage is 0%, and the description provides no hints about what values are expected or how they influence the assessment.

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?

Description clearly states the tool assesses Kubernetes posture using Kubescape, giving a specific verb and resource. It distinguishes itself from siblings by referencing Kubescape and the wrapper nature.

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

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says when to use the tool and directs users to connect Kubescape's own MCP server directly for significant Kubernetes work. Also advises vetting the third-party server, giving clear usage guidance.

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