Scavio for Python CLI Monolith vs Modular

The Problem

An r/Python post asked when to split a single-file CLI that grew to 4K LOC with 18 subcommands. Many teams split too early; the practical threshold is coupling, not LOC.

How Scavio Helps

• LOC alone is a poor signal — coupling and navigability matter more
• Single-file wins for debug, distribution, and onboarding
• Split when subcommands have genuine independent test surfaces
• Module-per-subcommand is the most common splitting shape
• Decision is reversible — start single, split when needed

Quick Start: Python Example

Here is a quick example searching Google for "Single-file 4K LOC CLI with 18 subcommands. Audit: which subcommands have independent state or independent test surfaces? Split those into modules; keep shared utilities at the top. Re-evaluate quarterly.":

import requests

API_KEY = "your_scavio_api_key"

response = requests.post(
    "https://api.scavio.dev/api/v1/search",
    headers={
        "x-api-key": API_KEY,
        "Content-Type": "application/json",
    },
    json={"query": query},
)

data = response.json()
for result in data.get("organic_results", [])[:5]:
    print(f"{result['position']}. {result['title']}")
    print(f"   {result['link']}\n")

Built for Python tool authors, OSS maintainers, devs building internal CLIs that crossed the 'is this still maintainable' line

Scavio handles the search infrastructure — proxies, CAPTCHAs, rate limits, and anti-bot detection — so you can focus on building your python cli monolith vs modular solution. The API returns structured JSON that is ready for processing, analysis, or feeding into AI agents.
