Learning from Claude Code’s own plugins

This article explores the Claude Code plugins directory, focusing on what the source code reveals about how Anthropic engineers structure agentic workflows. It highlights two plugins: feature-dev, which implements a 7-phase workflow for building features with dedicated agents (code-explorer, code-architect, code-reviewer) and patterns like asking clarifying questions and using TodoWrite to prevent drift; and ralph-wiggum, which uses a Stop hook to create a persistent loop for AI tasks. The author extracts practical rules of thumb for prompting and workflow design, making this a valuable resource for developers working with AI coding assistants.
