ncloud_get_pipeline_timezones

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

The readOnlyHint annotation already establishes the safe, read-only nature, and the 'Get' verb is consistent with it. The description adds only the value domain (timezones for schedule triggers) but does not disclose return format, whether the list is exhaustive, or any ordering/caching behavior.

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 a single, front-loaded sentence beginning with the verb 'Get', containing no filler or redundancy. Every word contributes meaning.

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 zero-parameter, read-only lookup with no output schema, the description adequately conveys the return value's purpose and scope. It is sufficiently complete for the tool's simplicity, though it could optionally mention the timezone value format.

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 has zero parameters, so the rubric establishes a baseline of 4. There are no parameter semantics to clarify, and the description correctly makes no parameter claims.

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 uses a specific verb ('Get') and a well-scoped resource ('available timezones for SourcePipeline schedule triggers'), making the tool's function immediately clear. It also distinguishes itself from the many pipeline sibling tools (list/get pipelines, history, etc.) by identifying a distinct metadata domain.

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?

The phrase 'for SourcePipeline schedule triggers' implies the usage context — the tool is relevant when configuring pipeline schedules. However, it does not explicitly state when to use it versus alternatives, nor does it mention any exclusions or prerequisites.

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