get_cluster

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

The description does not disclose behavioral traits such as what happens on error (e.g., invalid cluster_id), whether the operation is idempotent, or what data is returned. With no annotations provided, the description carries the full burden but fails to address these aspects.

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 (one phrase) but at the expense of essential details. Conciseness should not sacrifice clarity and completeness. The single sentence does not earn its place because it omits critical usage and behavior information.

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 tool's complexity (1 param, no output schema, no annotations), the description is insufficient. It fails to explain what a cluster is, what the tool returns, or any prerequisites. Sibling tools exist for similar actions, but the description provides no context to differentiate or guide usage.

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 input schema defines only 'cluster_id' as a required string, but parameter description coverage is 0%. The description adds no information about the parameter's format, purpose (e.g., OCID of the cluster), or how to obtain it. It does not compensate for the schema's lack of documentation.

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 OKE cluster' provides a verb and resource, indicating retrieval of a single OKE cluster. However, it lacks specificity on what is returned and does not differentiate from sibling tools like 'list_clusters' which lists all clusters. It is minimally clear but not detailed.

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 given on when to use this tool versus alternatives. Sibling tools include list_clusters, create_cluster, delete_cluster, etc., but the description does not indicate any selection criteria or context. The agent is left to infer usage from the name alone.

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