Context Engineering Kit

Hand-crafted collection of advanced context engineering techniques and patterns with minimal token footprint, focused on improving agent result quality.

The Claude Code plugin marketplace is based on prompts used daily by our company developers for a long time, while adding plugins from benchmarked papers and high-quality projects.

Key Features

Simple to Use - Easy to install and use without any dependencies. Contains automatically used skills and self-explanatory commands.
Token-Efficient - Carefully crafted prompts and architecture, preferring commands with sub-agents over skills when possible, to minimize populating context with unnecessary information.
Quality-Focused - Each plugin is focused on meaningfully improving agent results in a specific area.
Granular - Install only the plugins you need. Each plugin loads only its specific agents, commands, and skills. Each without overlap and redundant skills.
Scientifically proven - Plugins are based on proven techniques and patterns that were tested by well-trusted benchmarks and studies.

Quick Start

Step 1: Add the Marketplace

Open Claude Code

claude

Add the Context Engineering Kit marketplace

/plugin marketplace add NeoLabHQ/context-engineering-kit

This makes all plugins available for installation, but does not load any agents or skills into your context.

Step 2: Install Plugin

Install any plugins, for example reflexion

/plugin install reflexion@NeoLabHQ/context-engineering-kit

Each installed plugin loads only its specific agents, commands, and skills into Claude's context.

Step 3: Use Plugin

> claude "implement user authentication"
# Claude implements user authentication, then you can ask it to reflect on implementation

> /reflexion:reflect
# It analyses results and suggests improvements
# If issues are obvious, it will fix them immediately
# If they are minor, it will suggest improvements that you can respond to
> fix the issues

# If you would like it to avoid issues that were found during reflection to appear again, 
# ask claude to extract resolution strategies and save the insights to project memory
> /reflexion:memorize

Alternatively, you can use the

reflect

word in intial prompt:

> claude "implement user authentication, then reflect"
# Claude implements user authentication, 
# then hook automatically runs /reflexion:reflect

In order to use this hook, need to have

bun

installed. But for overral command in not required.
