-# OpenCodeReview CLI
-
-AI-powered code review tool that reads Git diffs, sends changed files to a configurable LLM via OpenAI-compatible API, and generates structured review comments. It goes beyond surface-level analysis — the Agent can read project context for deep reviews.
-
-## Install
-
-```bash
-npm install -g @alibaba-group/open-code-review
-```
-
-After installation, the `ocr` command is available globally.
-
-### Version Control
-
-```bash
-# Install specific version
-OCR_VERSION=v1.0.0 npm install -g @alibaba-group/open-code-review
-```
-
-## Prerequisites
-
-**You must configure an LLM provider before using `ocr`.** The tool requires access to an OpenAI-compatible API endpoint (OpenAI, Claude, local models, etc.).
-
-```bash
-ocr config set llm.url https://api.anthropic.com/v1/messages \
-    && ocr config set llm.auth_token {{your-api-key}} \
-    && ocr config set llm.model claude-opus-4-6 \
-    && ocr config set llm.use_anthropic true  \
-    && ocr config set language Chinese
-```
-
-Config is stored in `~/.opencodereview/config.json`.
-
-Or via environment variables:
-
-```bash
-export OCR_LLM_URL=https://api.anthropic.com/v1/messages
-export OCR_LLM_TOKEN=your-api-key
-export OCR_LLM_MODEL=claude-opus-4-6
-```
-
-### Test Connectivity
-
-```bash
-ocr llm test
-```
-
-## Quick Start
-
-Navigate to any Git repository and run:
-
-```bash
-# Review all workspace changes
-ocr review
-
-# Review diff between two branches
-ocr review --from main --to feature-branch
-
-# Review a single commit
-ocr review --commit abc123
-```
-
-## Commands
-
-| Command | Description |
-|---------|-------------|
-| `ocr review` / `ocr r` | Start code review |
-| `ocr config set <key> <value>` | Manage configuration |
-| `ocr llm test` | Test LLM connectivity |
-| `ocr viewer` | Start WebUI session viewer |
-| `ocr version` | Show version info |
-
-## Common Options
-
-| Flag | Shorthand | Default | Description |
-|------|-----------|---------|-------------|
-| `--repo` | | current dir | Git repository root |
-| `--from` | | | Source ref (e.g., `main`) |
-| `--to` | | | Target ref (e.g., `feature-branch`) |
-| `--commit` | `-c` | | Review a single commit |
-| `--format` | `-f` | `text` | Output format: `text` or `json` |
-| `--concurrency` | | `4` | Max concurrent file reviews |
-| `--timeout` | | `10` | Per-file timeout (minutes) |
-
-## Features
-
-- **Three review modes**: workspace changes, branch range, single commit
-- **Context-aware**: Agent reads arbitrary files, searches code via `git grep`, inspects diffs
-- **Plan phase**: Large changes (>50 lines) get risk analysis first
-- **Any LLM**: Works with OpenAI, Claude-compatible endpoints, local models
-- **Concurrent**: Files reviewed in parallel (configurable workers)
