kubernetes_get_cluster_kubeconfig

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

With no annotations, the description fully covers behavioral traits: it notes the return type (Scaleway file descriptor with base64-encoded content) and includes a strong security warning about cluster-admin credentials and trust requirements. No contradiction with annotations.

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 three sentences, each serving a distinct purpose: stating the action, describing the output format, and issuing a security warning. It is front-loaded with the main purpose and contains no fluff.

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 the presence of an output schema, the description adequately explains the return value and security implications. However, it lacks usage context (e.g., prerequisite of an existing cluster) and does not mention typical use cases, which slightly reduces completeness.

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 100%, so baseline is 3. The description does not add meaning beyond the schema for either region or cluster_id; it repeats 'cluster ID' without additional context. Thus, no extra value provided.

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 explicitly states 'Get the kubeconfig file for a Kubernetes cluster.' This clearly identifies the action (get) and resource (kubeconfig file), and it distinguishes itself from sibling tools like kubernetes_get_cluster or kubernetes_list_clusters by targeting the specific kubeconfig retrieval.

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 provide guidance on when to use this tool versus alternatives. It lacks context such as 'Use this after creating a cluster to obtain credentials' or comparisons to similar tools like kubernetes_get_cluster for cluster metadata.

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