Workflow v4.0.1-beta.49: Custom class serialization.

Your business logic stays in classes, not scattered across plain objects.

Custom Class Serialization in Workflow v4.0.1-beta.49

The Problem: Losing Your Domain Logic

Before Workflow v4.0.1-beta.49, building durable functions meant making a painful choice: either flatten your domain objects to plain JSON, or manually reconstruct them in every step.

OpenCode Plugin Logging Infrastructure

What We Did

Added comprehensive session-based file logging to all 8 OpenCode plugins in .opencode/plugin/. Each plugin now logs every hook invocation, whether it triggered an action or was skipped.

Files Created/Modified

.opencode/lib/logger.ts - Shared logging utility
All 8 plugins - Added logTriggered() and logSkipped() calls to every hook

OpenCode Plugins Guide

A comprehensive guide to writing plugins for OpenCode that extend agent behavior with hooks, custom tools, and event handling.

Quick Start

Create a TypeScript file in .opencode/plugin/ (project) or ~/.config/opencode/plugin/ (global)
Export a named plugin function
Restart OpenCode

Loading ZSH Functions into Claude Code

Make your shell functions and aliases available to Claude Code's Bash tool.

Setup

1. Create the Shell Init Script

Create ~/.claude/shell-init.sh:

	#!/bin/bash
	# BSP Split: Find largest pane IN CURRENT TAB and bisect it

	# Get current pane from environment (set by WezTerm for shells running in panes)
	if [ -n "$WEZTERM_PANE" ]; then
	CURRENT_PANE="$WEZTERM_PANE"
	else
	# Fallback: use the pane passed as argument
	CURRENT_PANE="$1"
	fi
