Imagen 4 AI Image Generator

Generate high-quality AI images using Google Imagen 4 via Media.io OpenAPI. Produces photorealistic, detailed images from text prompts with advanced text ren...

Security Scan

The skill's code, instructions, and required API key align with its stated purpose (calling Media.io's Imagen 4 endpoints); nothing requests unrelated credentials or performs unexpected network or file access, though there is a minor metadata mismatch about declared required env vars and the publisher/source are not verifiable.

Purpose & Capability

The skill's name and description (Imagen 4 via Media.io) match the included API definitions and the code implements calls to openapi.media.io. However, the registry metadata at the top-level reported 'Required env vars: none' while SKILL.md and the code require an API_KEY — this metadata mismatch should be corrected.

Instruction Scope

SKILL.md only instructs setting an API_KEY and using the provided Skill class to call listed Media.io endpoints. The instructions do not request or read unrelated files, secrets, or external endpoints beyond openapi.media.io. Usage examples and error handling are limited to the service.

Install Mechanism

No install spec is present (instruction-only + small local Python script). The only dependency indicated is 'requests' (pip) in examples — no downloads from arbitrary URLs or archives.

Credentials

The skill requires a single API_KEY (used as X-API-KEY) which is proportional to the stated purpose of calling Media.io APIs. Note the top-level registry metadata omitted this requirement — the SKILL.md and code do in fact require API_KEY.

Persistence & Privilege

always is false, the skill does not request elevated or persistent platform privileges, and it does not modify other skills or system-wide settings. It only reads its own local API definition file.

Assessment

This skill appears coherent: it requires one Media.io API key and only makes HTTPS requests to openapi.media.io (the code enforces the host). Before installing, confirm you trust the Media.io service and the skill author (source/homepage are not provided). Correct the metadata mismatch: SKILL.md and the code expect API_KEY while registry metadata listed none. Use a least-privilege API key (limited scope/credits) and review rate/credit implications. If you plan to run in a sensitive environment, inspect c_api_doc_detail.json to ensure endpoints are as expected and consider running the code in an isolated environment first.

Quick Start

1) Install Dependency

pip install requests

2) Initialize Skill

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

3) Configure Environment Variable API_KEY

Windows PowerShell:

$env:API_KEY="your-api-key"

macOS / Linux (bash/zsh):

export API_KEY="your-api-key"

Usage Examples (Python)

Basic Image Generation

import os
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

result = skill.invoke(
    'Imagen 4',
    {
        'prompt': 'a cute puppy, photorealistic, soft natural light, high detail',
        'ratio': '1:1',
        'counts': '1'
    },
    api_key=api_key
)
print(result)  # Returns task_id when code=0

Query Task Result

import os
import time
from scripts.skill_router import Skill

skill = Skill('scripts/c_api_doc_detail.json')
api_key = os.getenv('API_KEY', '')
if not api_key:
    raise RuntimeError('API_KEY is not set')

task_id = 'your-task-id'

for _ in range(24):
    r = skill.invoke('Task Result', {'task_id': task_id}, api_key=api_key)
    print(r)
    status = (r.get('data') or {}).get('status')
    if status in ('completed', 'failed', 'succeeded'):
        break
    time.sleep(5)

Task Status Reference

• waiting: queued
• processing: running
• completed: completed successfully
• failed: failed
• timeout: timed out

Error Handling

Error Code	Description
374004	Not authenticated. Apply for an APP KEY at https://developer.media.io/
490505	Insufficient credits. Recharge before invoking generation APIs
