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

With no annotations, the description should disclose behavioral traits. It mentions PATCH method but lacks details about destructive nature, potential downtime, rolling upgrade behavior, or constraints like version compatibility. This is insufficient for a cluster upgrade operation.

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?

Two concise sentences with no extraneous information. The first sentence front-loads the action and resource; the second provides implementation detail. Every word is necessary.

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 output schema, the description should explain expected outcomes, operation duration, or success indicators. It only states the action and method, leaving the agent uncertain about what happens after invocation (e.g., returns a job ID, long-running process).

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?

Since schema coverage is 100% and each parameter already has a clear description in the schema, the tool description adds no extra meaning beyond restating the method. Baseline 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 explicitly states the action (Upgrade the Kubernetes version) and the target resource (NKS cluster). It also mentions the HTTP method (PATCH) and parameter location (query parameters), distinguishing it from other NKS tools like create or delete.

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 (e.g., when a cluster upgrade is needed vs. other update operations). Prerequisites, conditions, or restrictions (e.g., target version must be higher than current) are absent.

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