## 🌟 Why git-air?
|
|
|
|
### The Pain Point: AI Writes Code Fast, But Reviewing It Is a Nightmare
|
|
|
|
Most developers today rely heavily on AI coding assistants (Cursor, Copilot, and LLM extensions). Generating hundreds of lines of code in seconds feels incredible.
|
|
|
|
**However, this introduces a critical new problem:**
|
|
- **The "Looks Perfect" Illusion**: AI-generated code features neat indentation, convincing naming, and flawless syntax, making it dangerously easy to trust blindly;
|
|
- **The Confirmation Bias of Generating Models**: In the same conversation thread, asking the very same AI *"Are there any bugs here?"* almost always yields a self-flattering response: *"The logic is completely solid and robust!"*;
|
|
- **Subtle Traps Missed by Human Eyes**: Overlooked unlocked mutexes on early `return` paths, missing `recover()` inside goroutines, unreleased database connections in loops... These critical traps easily slip past quick manual skimming.
|
|
|
|
This creates an absurd cycle: **AI mass-produces code, while human engineers spend late nights fixing production crashes.**
|
|

|
### The Solution: Shift Code Review Directly to Your Local Terminal (Pre-Commit)
|
|
|
|
While there are great cloud/CI-based PR review bots, **`git-air` is designed to be your independent, cold-blooded "third-party auditor" right inside your local terminal before you ever type `git commit`.**
|
|
|
|
Completely isolated from your chat history, it acts like a **grumpy but sharp senior architect sitting beside your desk**, ruthlessly inspecting only raw code changes (`git diff`):
|
|
|
|
- ⚡ **Git-Native Simplicity**: No workflow changes needed. Just run `git air` in your terminal for instant feedback.
|
|
- 🧠 **Universal Multi-Model Support**: Pre-configured support for **Google Gemini, Anthropic Claude, xAI Grok, DeepSeek, Local Ollama, OpenAI**, and any OpenAI-compatible custom endpoint.
|
|
- 🛡️ **Smart Noise Reduction**: Automatically strips out `go.sum`, `package-lock.json`, `*.pb.go`, and lockfiles to save tokens and eliminate review loops.
|
|
- 🎯 **Strict Senior Architect Persona**: Zero corporate fluff. Directly flags concurrency deadlocks, SQL injections, nil dereferences, and resource leaks with copy-paste code patches.
|
|
- 📋 **Team Rules Support (`.airules`)**: Drop an `.airules` file in your repo root, and the AI will prioritize your team-specific guidelines.
|
|
- 🪝 **One-Click Pre-commit Hook**: Mounts as a local Git hook in one command to block dangerous bugs before code is committed.

## 🚀 Quick Start
|
|
|
|
### 1. Configure Model & API Key
|
|
|
|
`git-air` comes with pre-configured endpoints and default models for all major AI providers. Simply pass `--provider`:
|
|
|
|
```bash
|
|
# 1. Google Gemini (Recommended: fast & cost-effective)
|
|
git air config set --provider gemini --key "YOUR_KEY"
|
|
|
|
# 2. Anthropic Claude (Claude-3.7 / 3.5 Sonnet)
|
|
git air config set --provider claude --key "YOUR_KEY" --model anthropic/claude-3.7-sonnet
|
|
|
|
# 3. xAI Grok (Grok-2 / Grok-3)
|
|
git air config set --provider grok --key "YOUR_KEY" --model grok-2-latest
|
|
|
|
# 4. DeepSeek (Deep reasoning)
|
|
git air config set --provider deepseek --key "YOUR_KEY" --model deepseek-chat
|
|
|
|
# 5. SiliconFlow (DeepSeek-V3 hosted)
|
|
git air config set --provider siliconflow --key "YOUR_KEY" --model deepseek-ai/DeepSeek-V3
|
|
|
|
# 6. Qwen / DashScope (Alibaba Cloud)
|
|
git air config set --provider qwen --key "YOUR_KEY" --model qwen-plus
|
|
|
|
# 7. Zhipu AI (GLM-4)
|
|
git air config set --provider zhipu --key "YOUR_KEY" --model glm-4-plus
|
|
|
|
# 8. Moonshot AI (Kimi)
|
|
git air config set --provider moonshot --key "YOUR_KEY"
|
|
|
|
# 9. Groq (Ultra-fast inference)
|
|
git air config set --provider groq --key "YOUR_KEY" --model llama-3.3-70b-versatile
|
|
|
|
# 10. OpenRouter (Universal AI Gateway)
|
|
git air config set --provider openrouter --key "YOUR_KEY"
|
|
|
|
# 11. 100% Offline Local Privacy (Ollama)
|
|
git air config set --provider ollama --model qwen2.5-coder
|
|
|
|
# 12. OpenAI Official (GPT-4o / o3-mini)
|
|
git air config set --provider openai --key "YOUR_KEY" --model gpt-4o-mini
|
|
```
|
|
|
|
Check current configuration:
|
|
```bash
|
|
git air config get
|
|
```
|
|
|
|

|
|
|
|
### 2. Everyday Commands
|
|
|
|
```bash
|
|
# Review currently staged changes (default)
|
|
git air
|
|
|
|
# Review the previous commit
|
|
git air HEAD~1
|
|
|
|
# Review differences between branches
|
|
git air main..feature-agent
|
|
|
|
# Review a specific file
|
|
git air internal/service/chat.go
|
|
|
|
# Temporarily override provider or model
|
|
git air --provider deepseek --model deepseek-chat
|
|
```
|
|
|

|
|
|
|
### 3. One-Click Git Pre-commit Hook
|
|
|
|
Install the hook inside any Git repository:
|
|
```bash
|
|
git air hook install
|
|
```
|
|
From now on, whenever you run `git commit`, `git-air` will automatically perform a code review in your terminal and warn you of any blocker issues!
|
|
|
|
To uninstall:
|
|
```bash
|
|
git air hook uninstall
|
|
```
|
|

|
|
## ⚙️ Configuration Hierarchy
|
|
|
|
`git-air` searches for configurations in the following priority order:
|
|
1. **CLI Flags** (`--key`, `--model`, `--provider`, `--prompt`)
|
|
2. **Environment Variables** (`GIT_AIR_API_KEY`, `GIT_AIR_PROVIDER`, `GIT_AIR_MODEL`)
|
|
3. **Project Config** (`./config.yaml` or `./.git-air.yaml` in repo root)
|
|
4. **Global User Config** (`~/.git-air/config.yaml`)
|
|
|

|
|
|
|
## 📋 Custom Team Rules (`.airules`)
|
|
|
|
Create an `.airules` file in your repository root. `git-air` will automatically inject these rules into the model with highest priority:
|
|
|
|
```markdown
|
|
# Team Coding Guidelines
|
|
1. All SQL operations must reside in the DAO/repository layer. No raw SQL string concatenation;
|
|
2. Concurrent shared variable access must use sync.RWMutex or sync/atomic;
|
|
3. Opened resource handles (DB rows, HTTP resp.Body, files) must be immediately closed via defer;
|
|
4. Never discard errors with blank identifiers (_ = err).
|
|
```
