## Project Overview
open-code-review is an open-source project written in Go: Secure, fast, efficient, battle-tested at Alibaba's scale. Hybrid architecture code review tool: deterministic pipelines + LLM Agent, precise line-level comments, built-in multi-language ruleset (NPE, thread-safety, XSS, SQL injection), OpenAI & Anthropic compatible.

Engineered for speed, consistency, and developer ease, it solves common hurdles in agent, agent-skills, code-review. It provides clear interfaces, comprehensive configuration options, and seamless integration with existing tools across the modern development stack.

## Key Features
- Optimized execution pipeline written in Go for predictable speed.
- Zero-friction configuration with comprehensive sensible defaults out of the box.
- Cross-platform runtime support across Linux, macOS, and Windows environments.
- Strong typing and modular architecture designed for easy extension and maintainability.
- Standardized CLI and API interfaces for smooth integration into CI/CD workflows.
- Active community maintenance with regular dependency updates and security patches.

## Installation & Quick Start

### macOS
```bash
go install github.com/alibaba/open-code-review@latest
```

### Windows
```bash
go install github.com/alibaba/open-code-review@latest
```

## System Requirements & Architecture
- **Supported Platforms**: macOS, Linux, Windows
- **Runtime Dependencies**: Go >= 1.21 runtime environment
- **Architecture**: x86_64, ARM64 (Apple Silicon & Graviton)

## How It Works
Open Code Review's core philosophy is to combine deterministic engineering with an agent, each handling what it does best. Deterministic Engineering — Hard Constraints For review steps that must not go wrong, engineering logic — not the language model — guarantees correctness: - Precise file selection — Determines exactly which files need review and which should be filtered, ensuring no important change is missed. - Smart file bundling — Groups related files into a single review unit (e.g., messageen.properties and messagezh.properties are bundled together). Each bundle runs as a sub-agent with isolated context — a divide-and-conquer strategy that stays stable on very large changesets and naturally supports concurrent review. - Fine-grained rule matching — Matches review rules to each file's characteristics, keeping the model's attention sharply focused and eliminating information noise at the source. Compared to purely language-driven rule guidance, template-engine-based rule matching is more stable and predictable.

## Production Use Cases
### Autonomous AI Agents
Orchestrate intelligent workflows and tool-calling routines with open-code-review.

### Model Inference & Prompting
Integrate fast, local or cloud-hosted generative AI models directly into production code.

### Context Memory & RAG
Augment language models with dynamic vector retrieval and structured project memory.

### Developer Productivity
Automate repetitive engineering tasks, code generation, and test creation using AI agents.

## Target Audience
Developers and engineering teams building with Go, seeking reliable, tested, and actively maintained tooling for production workloads.

## Strengths
- Active community backing with 49,289 GitHub stars and verified adoption.
- Permissive open-source distribution under the Apache-2.0 license.
- Built in Go for high execution speed and developer familiarity.
- Cross-platform compatibility across modern Linux, macOS, and Windows environments.
- Clean modular design allowing flexible configuration and pipeline integration.

## Considerations
- Requires familiarity with Go and modern CLI workflows.
- Ecosystem extensions may require manual configuration depending on environment constraints.
- Active development roadmap means breaking API changes may occur across major versions.
