🚀 Why BUJJI?

Feature	BUJJI	Cloud Agents
Privacy	🔒 100% local	☁️ Data leaves your machine
Cost	$0 (your hardware)	$$$ per token
Latency	<50ms (GPU)	500ms-5s (network)
Offline	✅ Fully works	❌ Requires internet
Customization	Full source access	Limited APIs
Context	Unlimited (your VRAM)	32K-128K tokens
Tools	13+ built-in, extensible	Vendor-locked

---

⚡ Quickstart

# 1. Install Ollama (if not installed)
curl -fsSL https://ollama.com/install.sh | sh

# 2. Pull a model (qwen3 recommended for tools)
ollama pull qwen3

# 3. Install BUJJI
pip install bujji

# 4. Run your first agent
python -c "
import asyncio
from bujji import Agent, LocalAgentConfig

async def main():
    agent = Agent(LocalAgentConfig(model='qwen3', provider='ollama'))
    async with agent:
        resp = await agent.chat('Write a Python script that fetches GitHub trending repos')
        print(await resp.text())

asyncio.run(main())
"

That's it. Your agent runs locally, writes code, uses tools, and remembers context — all on your machine.

✨ Features

🧠 Smart Agent Loop

• Automatic tool calling with parallel execution
• Error isolation per tool (one failure ≠ loop crash)
• Max 25 turns with configurable limits
• Streaming responses with thinking tokens

🪟 Infinite Context Window

• Automatic sliding window compression
• LLM-powered summarization of old turns
• Configurable trigger threshold (default 70%)
• Preserves recent turns + system prompt always

🛠️ 13+ Built-in Tools

Tool	Capability
filesystem	Read/write/list/glob/copy/move/delete
terminal	Safe shell execution with timeout
python_exec	Sandboxed Python with stdout capture
git	status, diff, log, commit, branch, push
github	Issues, PRs, search, repo management
web_search	Brave/DuckDuckGo/Tavily
browser	Playwright: navigate, click, screenshot, extract
docker	ps, images, build, run, exec, logs
documentation	Search & extract from docs sites

🔌 Extensible Providers

• Ollama (default) — local models
• OpenAI-compatible — vLLM, LM Studio, LocalAI
• OpenRouter — 100+ models via one API
• AirLLM — run 70B+ on consumer GPUs
• Custom — implement LLMProvider interface

🧩 MCP Integration

Connect to any Model Context Protocol server:

config = LocalAgentConfig(
    mcp_servers=[McpStdioServer(command="npx", args=["-y", "@modelcontextprotocol/server-github"])]
)

🪝 Hooks & Policies

from bujji.hooks import policy

config = LocalAgentConfig(
    policies=[policy.deny_tool("terminal")],  # Block dangerous tools
    hooks=[my_custom_hook],
)

💾 Dual-Backend Memory

• SQLite — fast keyword search, metadata
• ChromaDB — semantic vector search
• Automatic embedding + retrieval

📋 Planning & Routing

• Task decomposition into subtasks
• Confidence-based routing (local vs escalate)
• Structured output with Pydantic schemas

🛠️ Tools Deep Dive

from bujji import Agent, LocalAgentConfig, types

# All tools enabled by default
config = LocalAgentConfig(
    model="qwen3",
    capabilities=types.CapabilitiesConfig(
        enabled_tools=types.BuiltinTools.all_tools()
    )
)

Tool	Use Case	Example
filesystem	File operations	"Read all .py files in src/"
terminal	Run commands	"Run pytest and show failures"
python_exec	Execute code	"Calculate fibonacci(50)"
git	Version control	"Show diff of last 3 commits"
github	GitHub API	"Create issue: bug in login"
web_search	Search web	"Latest Rust 1.80 features"
browser	Web automation	"Screenshot github.com/trending"
docker	Container ops	"Build and run my Dockerfile"
documentation	Doc lookup	"FastAPI dependency injection"

🏗️ Architecture

┌─────────────────────────────────────────────────────────────┐
│                        LAYER 1: Agent                       │
│  High-level API, hooks, policies, MCP, triggers, memory, planner, router
├─────────────────────────────────────────────────────────────┤
│                      LAYER 2: Conversation                  │
│  Stateful session: chat(), send/receive steps, history, usage tracking
├─────────────────────────────────────────────────────────────┤
│                      LAYER 3: Connection                    │
│  LocalConnection: tool loop, context window, provider abstraction
├─────────────────────────────────────────────────────────────┤
│  Providers: Ollama │ OpenAI │ OpenRouter │ AirLLM │ Custom  │
│  Tools: 13 built-in + MCP + custom callables                │
└─────────────────────────────────────────────────────────────┘

Three-layer design lets you swap any component:

• Use Agent for batteries-included experience
• Use Conversation + Connection for custom loops
• Use LLMService + ToolRunner for bare-metal control

💡 Examples

Code Generation Agent

from bujji import Agent, LocalAgentConfig

agent = Agent(LocalAgentConfig(
    model="qwen3",
    system_instructions="You are a senior Python developer. Write clean, typed, tested code."
))
async with agent:
    resp = await agent.chat("""
    Create a FastAPI app with:
    - JWT authentication
    - PostgreSQL + SQLAlchemy async
    - Redis caching
    - Pytest fixtures
    - Dockerfile
    """)
    print(await resp.text())

Research Agent with Web + Browser

agent = Agent(LocalAgentConfig(
    model="qwen3",
    capabilities=types.CapabilitiesConfig(
        enabled_tools=["web_search", "browser", "filesystem"]
    )
))
async with agent:
    resp = await agent.chat("""
    Research the latest techniques for quantization of LLMs.
    Search web, browse top papers, save summary to research.md
    """)
    print(await resp.text())

GitHub Automation Agent

agent = Agent(LocalAgentConfig(
    model="qwen3",
    capabilities=types.CapabilitiesConfig(
        enabled_tools=["github", "git", "terminal", "filesystem"]
    )
))
async with agent:
    resp = await agent.chat("""
    1. Check open issues labeled 'good first issue' in microsoft/vscode
    2. Pick one, create a branch, implement a fix
    3. Open a PR with description
    """)
    print(await resp.text())

Streaming with Thinking

async with agent:
    resp = await agent.chat("Solve this step by step: ...")
    async for chunk in resp:
        if isinstance(chunk, types.Thought):
            print(f"💭 {chunk.text}", end="", flush=True)
        elif isinstance(chunk, types.Text):
            print(chunk.text, end="", flush=True)
