get_current_cluster

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It implies a read operation ('Get') but doesn't disclose whether this requires specific permissions, what happens if no cluster is set, error conditions, or the format of the returned cluster information. The ':return:' placeholder suggests output documentation is incomplete.

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 brief but includes an incomplete ':return:' section that adds no value. The first sentence is clear and front-loaded, but the second fragment is wasted space. It could be more concise by removing the placeholder or expanding it meaningfully.

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 no annotations and no output schema, the description is insufficient for a Kubernetes cluster tool. It doesn't explain what 'current cluster' means in Kubernetes context, how it's determined from kubeconfig, or what the return value contains. For a tool in a complex system like Kubernetes, more context is needed to use it effectively.

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?

The tool has 0 parameters with 100% schema description coverage, so the schema fully documents the lack of inputs. The description doesn't need to add parameter semantics, and it correctly avoids mentioning any parameters. A baseline of 4 is appropriate for a zero-parameter tool with complete schema coverage.

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 the action ('Get') and resource ('current cluster from the kubeconfig file'), making the purpose immediately understandable. It distinguishes from sibling 'get_clusters' by specifying 'current' cluster rather than listing all clusters. However, it doesn't fully differentiate from other read operations like 'clusterrole_get' or 'configmap_get' beyond the resource type.

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. It doesn't mention prerequisites (e.g., having a valid kubeconfig), when this is needed versus 'get_clusters', or any context about Kubernetes operations. The agent must infer usage from the tool name alone.

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