Claude Code Skills for software engineering workflows - Git automation, testing, and code review
Based on the README, here's a technical summary: Provides modular Claude Code plugins (Engineering Workflows, Visual Documentation, Code Operations, Productivity Skills) that activate contextually through declarative SKILL.md and AGENT.md files—enabling Git automation, testing, code review, visual diagram generation, and code refactoring without explicit user invocation. Implements the Anthropic code execution pattern via a sandboxed FastMCP server runtime, achieving 90-99% token reduction for bulk operations by executing Python locally rather than processing files through context.
