What it does
Postman Openapi Converter is an agent skill from sickn33/agentic-awesome-skills. Convert OpenAPI 3.x or Swagger 2.0 specs (YAML or JSON) into complete, import-ready Postman Collection v2.1 JSON files.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering OpenAPI specifications and API testing. It works with OpenAPI and Postman. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

- Tasks that involve OpenAPI specifications
- Tasks that involve API testing
Example prompts

Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Postman Openapi Converter loads about 1.5k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 661 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

OpenAPI → Postman Collection Converter
When to Use
Use this skill when you need convert OpenAPI 3.x or Swagger 2.0 specs (YAML or JSON) into complete, import-ready Postman Collection v2.1 JSON files. Use this skill whenever the user provides or references an OpenAPI spec, Swagger file, openapi.yaml, swagger.json, or uses phrases like "convert my OpenAPI spec",...
Converts OpenAPI 3.x or Swagger 2.0 specs into a valid Postman Collection v2.1.
Step 1 — Detect & Validate Input
Identify the spec version from the input:
openapi: 3.x.x→ OpenAPI 3swagger: "2.0"→ Swagger 2
If the input is truncated or partial, convert what's available and note missing sections.
Step 2 — Extraction Mapping
OpenAPI 3 → Postman
| OpenAPI field | Postman mapping |
|---|---|
info.title | Collection name |
info.description | Collection description |
servers[0].url | {{base_url}} variable |
paths.<path>.<method> | One request item per operation |
operationId or summary | Request name |
parameters (path/query/header) | URL path variables, query params, headers |
requestBody.content.application/json.schema | Body (raw JSON), generate example from schema |
responses | Saved example responses |
components.securitySchemes | Collection-level auth |
tags | Folder grouping |
Swagger 2 → Postman
| Swagger field | Postman mapping |
|---|---|
host + basePath | {{base_url}} |
paths.<path>.<method> | Request item |
parameters | Query/path/header/body params |
consumes / produces | Content-Type / Accept headers |
securityDefinitions | Collection auth |
tags | Folders |
Step 3 — Generate Example Bodies
For each request with a requestBody or body parameter, generate a realistic example JSON body from the schema:
- Use property names as keys
- Infer sensible example values from type + format (e.g.,
"email"format →"user@example.com","date-time"→"2024-01-15T10:30:00Z") - For
$refschemas, resolve them inline
Step 4 — Auth Handling
Map security schemes to Postman auth:
| OpenAPI scheme | Postman auth type |
|---|---|
http: bearer | bearer with {{token}} |
http: basic | basic with {{username}} / {{password}} |
apiKey: header | apikey header with {{api_key}} |
apiKey: query | apikey query param |
oauth2 | oauth2 (note: requires manual token setup) |
Apply auth at collection level if all endpoints share the same scheme. Override at request level for exceptions.
Step 5 — Build Collection JSON
Use the standard v2.1 structure (same schema as postman-collection-generator skill).
Key differences for spec-converted collections:
- Always group by
tagsinto folders - Include
descriptionfield on each request fromoperationId+summary+description - Add saved example responses where
responsesare defined in the spec
"response": [
{
"name": "200 OK",
"status": "OK",
"code": 200,
"header": [{ "key": "Content-Type", "value": "application/json" }],
"body": "{ \"id\": 1, \"name\": \"example\" }",
"originalRequest": { <copy of the request> }
}
]Step 6 — Environment File
Extract all variables into a companion environment:
base_urlfromservers[0].urlorhost + basePathtoken,api_key,username,passwordas empty placeholders- Any server variables from
servers[0].variables
Step 7 — Output
collection.json— Full Postman Collection v2.1environment.json— Matching environment file- Conversion summary: number of endpoints converted, folders created, auth type detected, any fields skipped or approximated

Edge Cases
$refchains: Resolve all$refpointers inline before mappingallOf/oneOf/anyOf: Use the first/primary schema for body generation; note alternatives in description- Path parameters: Convert
{param}to:paramin URL path AND add tovariablearray in url object - Multiple content types: Prefer
application/json; note others in request description - No operationId: Generate name from
METHOD /path(e.g.,GET /users/{id}→Get User by ID)
Quality Checklist
- Every
pathsentry produces at least one request - Path params use
:paramformat in Postman URL - All
$refresolved — no raw$refstrings in output - Auth tokens are
{{variables}}, never hardcoded - JSON output is valid and importable
After Completing the API Design
Once the API design output is delivered, ask the user:
"Would you like me to generate API documentation for this design? (yes/no)"
If the user says yes:
- Check if the API Documentation skill is available in the installed skills list
- If the skill is available:
- Read and follow the instructions in the API Documentation skill
- Use the API design output above as the input
- If the skill is NOT available:
- Inform the user: "It looks like the API Documentation skill isn't installed. You can install it and re-run.
If the user says no:
- End the task here
Limitations
- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
