ncloud_dataflow_create_workflow

Create a data pipeline workflow by defining nodes (source, filter, sink) and connecting them with edges.

Instructions

Create a new Data Flow workflow. A workflow defines the data pipeline with nodes (source, filter, sink) and edges connecting them.

Behavior2/5

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

The description does not disclose behavioral traits beyond what annotations (destructiveHint: false) already indicate. It doesn't mention idempotency, validation, or side effects. The explanation of 'workflow' adds context but not behavior.

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 concise with two sentences and front-loads the primary action. However, it lacks usage guidance, which could be added without significant length.

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?

For a tool with 5 parameters and no output schema, the description explains what a workflow is but does not cover return values, required parameters, or the behavior of dryRun. It is adequate but not comprehensive.

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 baseline is 3. The description adds no additional meaning beyond the parameter descriptions in the schema. No parameter is elaborated.

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

Purpose5/5

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

The description clearly states the verb 'Create' and resource 'Data Flow workflow', and briefly explains what a workflow is. It distinguishes from sibling tools like get, update, delete, and list operations.

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 provides no guidance on when to use this tool versus alternatives like ncloud_dataflow_update_workflow or ncloud_dataflow_list_workflows. There is no mention of prerequisites or context.

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