createCollection

Create a Postman API collection from a schema definition, with optional workspace assignment.

Instructions

Creates a collection using the Postman Collection v2.1.0 schema format.

Note:

If you do not include the `workspace` query parameter, the system creates the collection in the oldest personal Internal workspace you own.

Behavior3/5

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

Annotations already indicate non-readonly and non-destructive behavior. The description adds the default workspace context but does not mention side effects or response format, which is minimal beyond what annotations provide.

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

Conciseness5/5

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

The description is two sentences, front-loaded with purpose, and the note is clearly separated. Every sentence adds value without redundancy.

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

Completeness2/5

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

Given the complex nested schema and no output schema, the description lacks completeness. It does not explain required fields (info.name, info.schema), the purpose of the collection object, or what the tool returns, leaving the agent to infer entirely from the schema.

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

Parameters2/5

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

Schema coverage is 50%, and the description only explains the 'workspace' parameter through its default note. The 'collection' parameter's structure and requirements are left entirely to the schema, with no additional guidance in the description.

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 'Creates' and the resource 'collection' referencing the Postman Collection v2.1.0 schema. It distinguishes from sibling tools that create sub-resources like requests or specs.

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

Usage Guidelines3/5

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

The description provides a useful note about default workspace behavior when the 'workspace' parameter is omitted, but offers no guidance on when to use this tool versus alternatives (e.g., createCollectionRequest) or prerequisites.

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