## 📦 Install

```bash
# script install
curl -fsSL https://huggingface.co/chenbhao/codev/raw/main/install.sh | bash

# source install
git clone https://huggingface.co/chenbhao/codev && cd codev && bun install && bun run build && codev

# if want global use bin file
# cp dist/codev ~/.local/bin
ln -sf dist/codev ~/.local/bin/codev

# then can use Codev in everywhere after `/login`
```

### Git LFS & Xet (faster large-file transfer)

Asset files (images, screenshots) are tracked via Git LFS.
Install the **git-xet** custom transfer agent to replace the standard LFS protocol with
Xet's chunk-dedup transport for much faster push/pull:

```bash
curl --proto '=https' --tlsv1.2 -sSf \
  https://raw.githubusercontent.com/huggingface/xet-core/refs/heads/main/git_xet/install.sh | sh
git xet install
```

After setup, use normal git workflow — `git-xet` automatically handles LFS objects:

```bash
git lfs pull   # download all large files
```

## 🚀 Quick Start

> [!IMPORTANT]
> If you no need `auto-compact / dream / control context-window`
> and `websearch` feature. you can no configuration anything
>
> if you no need free `local-websearch` you can skip config `searxng``
> and just set`TAVILY_API_KEY` in env

```bash
# Maximum_Context_Window = min(CLAUDE_CODE_MAX_CONTEXT_TOKENS, CLAUDE_CODE_AUTO_COMPACT_WINDOW) - 20000
# set 200k env in ~/.claude/settings.json or terminal
# the 20k is used to compact as buffer band
# set tool_search env
# set agentteam in tmux

}
```

```bash
# Config SearXNG
# 1. docker configuration
# local config search engine - searxng in archlinux
# make sure have install docker and docker-compose
sudo pacman -S docker-compose && docker
docker --version && docker compose version
sudo usermod -aG docker $USER

# make sure open pc and now start docker daemon
sudo systemctl enable --now docker

# 2. docker-compose pull
# use VersperSearch a pre-build docker config in https://github.com/chenbhao/VersperSearch
# or install searxng in docker-compose by yourself
curl -fsSL \
-O https://raw.githubusercontent.com/searxng/searxng/master/container/docker-compose.yml \
-O https://raw.githubusercontent.com/searxng/searxng/master/container/.env.example

# add json source in formats behind html - jsonl in 87 lines
cd searxng/core-config/ && sudo nvim settings.yml

# start searxng engine
docker compose up -d

# 3. check search feature
# check in every browser
firefox http://localhost:8080
```

```bash
# test

### Auto Compact & Dream & SubAgent

#### 🧠 Core Mechanisms of Cycle Long Run

- Auto Compact — Automatically optimizes and compresses historical context to bypass sequence length bottlenecks.
- Dream — Asynchronously distills operational data into long-term insights.

#### 🗂️ SubAgent Swarm Topology

| SubAgent Type | Core Responsibility |
| :--- | :--- |
| 🛡️ **General-Purpose** | Orchestrates routing, high-level user interaction, and dispatching. |
| 🔍 **Explore** | Conducts deep semantic search and autonomous tool discovery. |
| 📋 **Plan** | Handles multi-step chain-of-thought strategy and task decomposition. |
| 🧪 **Verification** | Executes automated runtime validation, assertion checks, and fault tolerance. |
