// 1h agoOPENSOURCE RELEASE

OpenAI open-sources a repository of Codex plugin examples to package custom skills, integrations, and MCP servers into reusable developer workflows.

The `openai/plugins` repository provides a curated set of Codex plugin examples to streamline the creation of role-specific developer workflows. By structuring plugins with a `.codex-plugin/plugin.json` manifest, developers can package model-readable instructions (skills), application integrations (e.g., Slack, Notion, Remotion, and Figma), and Model Context Protocol (MCP) servers into cohesive bundles. These plugins are discoverable via a marketplace format and can be managed directly using the Codex CLI or user interface, enabling agents to execute complex, tool-based tasks.

// ANALYSIS

Unifying custom model instructions, API manifests, and Model Context Protocol (MCP) servers under a single plugin framework is a major step toward standardized agentic developer workflows.

* **Unified Packaging**: Combining skills, application integrations, and MCP configurations under one manifest simplifies agent tool distribution.

* **MCP Integration**: Native support for MCP servers allows developer agents to seamlessly tap into a growing open standard for executing local and remote tools.

* **Actionable Examples**: Providing production-ready templates for iOS, macOS, web development, Figma, and Notion gives developers high-quality, practical starting points.

* **Simplified Toolchain**: Discovery and management are kept simple through CLI commands like `npx codex-marketplace add`, enhancing developer velocity.

Pieter Levels ships browser dot-matrix printer

Pieter Levels has successfully created a simulated dot matrix printer integrated with an emulated Windows 3.11 browser environment running via DOSBox. Built over the course of a year with assistance from Claude Code, the project routes printer data from the emulated OS's COM2 port to a virtual green-bar fanfold paper canvas in the browser. Users can test the system by configuring the default printer connection in the Windows Control Panel and printing text files from legacy applications like Notepad.
