Hand-crafted Claude Code Skills focused on improving agent results quality. Compatible with OpenCode, Cursor, Antigravity, Gemini CLI, and others. Includes CodeRabbit open-source alternative.

About the project

Context Engineering Kit is a collection of skills, agents, hooks, instructions, commands, and plugins that shape how coding agents use context and carry out development work. It is for developers using Claude Code and other supported coding agents who want more predictable results. The catalogue entries are components from this collection.

This repository also configures its own agents. See what context-engineering-kit tells them →

NeoLabHQ/context-engineering-kit

Agent Claude Code

Use this agent when implementing a single step of a task. Receives the task file path AND that step's sub-task file path. Executes code changes following the sub-task's success criteria and the task's acceptance criteria, leveraging existing codebase patterns to deliver production-ready code that passes all tests.
