TDQS

B3.2/5.0
Behavior3/5

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It correctly implies a read-only operation ('Get detailed information'), but does not mention whether the tool works with zone/region combinations, what happens if the cluster doesn't exist, or if it requires authentication—common behavioral gaps for a describe tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with minimal waste. It could be slightly more specific (e.g., what 'detailed information' includes), but it is well-structured and immediately accessible.

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

Completeness3/5

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

Given the moderate complexity (3 params, no output schema, no nested objects, no annotations), the description is somewhat complete for a simple read operation. However, without specifying the output format or behavior for missing clusters, the agent lacks full operational context to use the tool robustly.

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

Parameters3/5

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

Schema coverage is 100%, so the schema already documents all parameters with descriptions. The description adds no additional parameter context beyond what the schema provides, which is expected at this coverage level. A 3 reflects the adequate baseline where description doesn't need to compensate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a clear verb ('Get') and specifies the resource ('specific GKE cluster'), making the core purpose obvious. However, it does not differentiate from sibling tools like gcloud_container_clusters_list or gcloud_container_clusters_get_credentials, which could be confused with this inspection tool.

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

Usage Guidelines2/5

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

The description offers no guidance on when to use this tool versus alternatives (e.g., when to use list vs describe, or what additional info describe provides), and no mention of prerequisites or context. Without this, the agent lacks decision support for tool selection.

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