generateCollection

Create a collection from an API specification. Provide an existing spec ID and choose options like request naming, folder strategy, and parameter generation.

Instructions

Creates a collection from the given API specification. The specification must already exist or be created before it can be used to generate a collection. The response contains a polling link to the task status.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
specIdYesThe spec's ID.
elementTypeYesThe `collection` element type.
nameYesThe generated collection's name.
optionsYesThe advanced creation options and their values. For more details, see Postman's [OpenAPI to Postman Collection Converter OPTIONS documentation](https://github.com/postmanlabs/openapi-to-postman/blob/develop/OPTIONS.md). These properties are case-sensitive.
Behavior4/5

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

Annotations indicate it is not read-only (readOnlyHint=false) and not destructive, aligning with creation. The description adds value by disclosing the async behavior with a polling link in the response. No contradictions with annotations.

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?

Three sentences, all essential: purpose, prerequisite, async behavior. No waste.

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

Completeness4/5

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

Given the complexity of options and lack of output schema, the description covers the key aspects: creation, prerequisite, and async response. Missing details on task status structure, but adequate overall.

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% with detailed descriptions for all parameters, including nested options. The description adds no additional meaning beyond the schema, so baseline of 3 is appropriate.

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', resource 'collection', and source 'from the given API specification'. It distinguishes from siblings like createCollection (empty collection creation) and generateSpecFromCollection (reverse).

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

Usage Guidelines4/5

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

The description provides a prerequisite: 'The specification must already exist or be created before it can be used.' It also mentions the async polling link. However, it does not explicitly guide when to use this vs alternatives like createCollection.

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