ibmcloud_ks_cluster

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

With no annotations provided, the description carries the full burden, but it only states 'Get cluster details' with no mention of output format, required authentication, side effects, or limitations. It implies a read-only operation but adds no behavioral context beyond what the name conveys.

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 extremely concise at three words, with no filler. However, it sacrifices detail for brevity, so it earns a 4 rather than 5.

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?

For a simple one-parameter read operation, the description is minimally viable but lacks details about what 'details' are returned and how this differs from other cluster-related tools. Given the absence of an output schema, more explanation would improve 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?

The schema fully covers the single 'cluster' parameter with 'Cluster name or ID', achieving 100% schema description coverage. The description adds no additional meaning, so the baseline of 3 is appropriate.

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 'Get cluster details' has a specific verb ('Get') and resource ('cluster details'), making the purpose clear. It distinguishes from siblings like ibmcloud_ks_clusters (list) and ibmcloud_ks_cluster_config (configuration) by implying a single cluster's details, though it doesn't explicitly name alternatives.

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?

No guidance is provided on when to use this tool versus alternatives like ibmcloud_ks_clusters or ibmcloud_ks_cluster_config. While the sibling names imply different purposes, the description itself offers no contextual usage instructions or exclusions.

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