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.
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
Skill Claude CodeCodex
Review your local uncommitted working-tree changes (git diff plus untracked files) and return actionable improvement suggestions. Use before committing, when nothing has been pushed yet.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Review an existing GitHub pull request and post inline review comments on its diff. Use when the changes are on an opened PR rather than your local working tree.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior.

Skill Claude CodeCodex
Display the current state of the FPF knowledge base.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use when executing implementation plans with independent tasks in the current session or facing 3+ independent issues that can be investigated without shared state or dependencies - dispatches fresh subagent for each task with code review between tasks, enabling fast iteration with quality gates.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use after writing tests to assess coverage quality across structural, mutation, requirements, and API/integration dimensions; organized knowledge for choosing and interpreting coverage analyses.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use when creating or editing any prompt (commands, hooks, skills, subagent instructions) to verify it produces desired behavior - applies RED-GREEN-REFACTOR cycle to prompt engineering using subagents for isolated testing.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Use when tackling complex reasoning tasks requiring step-by-step logic, multi-step arithmetic, commonsense reasoning, symbolic manipulation, or problems where simple prompting fails - provides comprehensive guide to Chain-of-Thought and related prompting techniques (Zero-shot CoT, Self-Consistency, Tree of Thoughts…

This skill should be used when need prioritize what changed code in repository human must review.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Execute tasks through systematic exploration, pruning, and expansion using Tree of Thoughts methodology with meta-judge evaluation specifications and multi-agent evaluation.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Update and maintain project documentation for local code changes using multi-agent workflow with tech-writer agents. Covers docs/, READMEs, JSDoc, and API documentation.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Iterative Five Whys root cause analysis drilling from symptoms to fundamentals.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Apply writing rules to any documentation that humans will read. Makes your writing clearer, stronger, and more professional.
NeoLabHQ/context-engineering-kit
Skill Claude CodeCodex
Add missing test coverage for your local code changes by generating new test files (covers uncommitted and untracked changes, or the latest commit if everything is committed). Use when you want write tests for new logic or increase test coverage.
