scale_tkc_cluster

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

Annotations indicate a non-read-only, non-destructive, non-idempotent operation with open-world semantics. However, the description adds no behavioral context beyond the annotations, such as the impact of scaling down (e.g., potential termination of workloads) or whether scaling is a rolling update.

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 concise with only a title and a brief Args list. No extraneous words; however, the Args section largely repeats schema fields without meaningful elaboration, slightly reducing effectiveness.

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 complexity of scaling a TKC cluster and the lack of output schema, the description is insufficient. It fails to explain side effects, whether scaling is rolling, or if scaling to 0 is allowed. The tool requires more context for correct invocation.

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 description lists three required parameters (name, namespace, worker_count) and adds a constraint for worker_count (>= 1) not present in the schema. However, it omits the optional 'target' parameter entirely, and schema coverage is 0%, leaving the description partially compensating.

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 '[WRITE] Scale TKC cluster worker node count,' specifying a verb and resource. It distinguishes this tool from siblings like 'create_tkc_cluster' and 'delete_tkc_cluster' by focusing on scaling worker nodes.

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 'upgrade_tkc_cluster' or 'create_tkc_cluster.' There is no mention of prerequisites (e.g., cluster must exist) or constraints on scaling.

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