Use Your ChatGPT Subscription for AI Coding Workloads

The Problem

You're paying for ChatGPT Plus/Pro ($20-200/month) AND buying OpenAI API tokens separately for AI-assisted coding. That's double-dipping.

The Solution

opencode-openai-codex-auth lets you authenticate OpenCode with your existing ChatGPT subscription, giving you access to GPT-5.x models for coding tasks without purchasing additional API credits.

Build Unlimited AI Agents for $200/month

Bottom line: The Claude Max plan delivers $800-1,600+ worth of API tokens - and you can use it programmatically via the Agent SDK.

Plan	Monthly Cost	API Token Value	ROI
Pro	$20	~$40-80	2-4x
Max 5x	$100	~$200-400	2-4x
Max 20x	$200	~$800-1,600+	4-8x

MCP-DSL Token Efficiency Experiment Results

Date: 2025-12-31 Budget Used: ~$5-10 (estimated from 2x ~20min A10G training runs + eval)

Summary

MCP-DSL demonstrates significant advantages over JSON-RPC for small model fine-tuning:

Resilient SSH Port Forwarding on macOS with launchd

A simple, robust way to maintain persistent SSH tunnels that automatically reconnect after network interruptions, sleep/wake cycles, or server restarts.

Overview

Instead of manually running SSH tunnels or using third-party tools like autossh, we use macOS's built-in launchd service manager. It handles:

Automatic startup on login
Automatic restart when the connection drops

Docker Container Hardening Plan for Dokploy

This guide hardens Docker container isolation on a system running Dokploy with untrusted public templates.

Overview

Step	Action	Risk Level
1	Backup current configuration	None
2	Apply Docker daemon security defaults	Low

Mount Remote Server (dokploy) via SSHFS on macOS

This guide documents how to mount a remote server's directory as a network drive on macOS using SSHFS.

Prerequisites

macOS (tested on macOS Sequoia)
SSH access to remote server configured in ~/.ssh/config
Homebrew installed

Testing Dokploy Webhook Endpoints

Problem

When attempting to manually test a Dokploy webhook endpoint for auto-deployment, the API returns a "Branch Not Match" error:

{
    "message": "Branch Not Match"
}
