Skill HaibaraAiAPTX/frontend-openapi-skills/skills/download-openapi

Download remote OpenAPI/Swagger JSON specification from a URL to local file using aptx-ft CLI. TRIGGER when user mentions: (1) fetch/pull/download swagger or openapi from URL, (2) save API spec to openapi.json locally, (3) get API documentation from server, or (4) prepare local input for code generation. DO NOT TRIGGER when: generating code/types from local file, reading existing openapi.json, downloading non-OpenAPI files, or authentication is required.From its SKILL.md

Download OpenAPI JSON

Download OpenAPI 3.x JSON specification from a remote URL.

Prerequisites

pnpm add -D @aptx/frontend-tk-cli

Usage

pnpm exec aptx-ft input download --url <url> --output <file>

Alternative (without pnpm):

npx aptx-ft input download --url <url> --output <file>

Example

pnpm exec aptx-ft input download --url https://api.example.com/swagger.json --output ./openapi.json

Workflow

Confirm the OpenAPI URL with user
Choose output path (recommended: ./openapi.json)
Execute download command
Pass the file path to other skills (generate-models, generate-artifacts)

Output

Local OpenAPI JSON file (e.g., ./openapi.json)

Boundaries

This skill only handles OpenAPI JSON format downloads:

Does NOT support YAML format
Does NOT handle authenticated URLs (Bearer Token, etc.)
Does NOT support custom request headers
Only validates JSON syntax, not OpenAPI specification validity

For these cases, download manually and use other tools.
