TakoBull: Ultra-Efficient AI Assistant in Rust

$10 Hardware · 10MB RAM · 1s Boot · 🤖 Powered by Rust

🤖 TakoBull is an ultra-lightweight personal AI Assistant, a high-performance Rust port of PicoClaw. Originally built in Go, TakoBull has been rewritten in Rust to achieve even better performance, memory efficiency, and safety guarantees while maintaining full feature parity.

⚡️ Runs on $10 hardware with <10MB RAM: That's 99% less memory than traditional AI assistants and 98% cheaper than a Mac mini!

🪶 Ultra-Lightweight: <10MB Memory footprint — 99% smaller than traditional AI assistants.

💰 Minimal Cost: Efficient enough to run on $10 Hardware — 98% cheaper than a Mac mini.

⚡️ Lightning Fast: 400X Faster startup time, boot in 1 second even on 0.6GHz single core.

🌍 True Portability: Single self-contained binary across RISC-V, ARM, and x86.

⚡ High Performance: Memory-safe, high-performance implementation with zero-cost abstractions.

• Install Rust from https://rustup.rs/

# Clone the repository
git clone git@github.com:kactlabs/takobull.git
cd takobull

# Build in release mode (optimized for embedded)
cargo build --release

# Binary location: target/release/takobull

# Install the binary to ~/.cargo/bin/
cargo install --path .

# Now you can run from anywhere:
takobull agent -m "What is 2+2?"

takobull onboard

This creates ~/.takobull/ with default configuration.

Edit ~/.takobull/config.yaml and set your API key:

agents:
  defaults:
    provider: openai
    model: gpt-4-mini
    workspace: ~/.takobull/workspace

providers:
  openai:
    api_key: "your-api-key-here"
    api_base: "https://api.openai.com/v1"

# Send a message
takobull agent -m "Write a Python function to sort a list"

# Override provider and model for a single execution
takobull agent -p openai --md gpt-4-mini -m "What is 2+2?"
takobull agent -p gemini --md gemini-2.5-flash -m "Explain Rust ownership"
takobull agent -p ollama --md llama2 -m "Write a hello world in Python"

# Start the gateway (for channel integrations)
takobull gateway

# Check system status
takobull status

# Manage scheduled tasks
takobull cron list

Config file: ~/.takobull/config.yaml

TakoBull stores data in your configured workspace (default: ~/.takobull/workspace):

~/.takobull/workspace/
├── sessions/          # Conversation sessions and history
├── memory/           # Long-term memory
├── state/            # Persistent state
├── cron/             # Scheduled jobs database
├── skills/           # Custom skills
└── files/            # User files

TakoBull runs in a sandboxed environment by default. The agent can only access files and execute commands within the configured workspace.

agents:
  defaults:
    workspace: ~/.takobull/workspace
    restrict_to_workspace: true

When restrict_to_workspace: true, the following tools are sandboxed:

If you need the agent to access paths outside the workspace:

agents:
  defaults:
    restrict_to_workspace: false

⚠️ Warning: Disabling this restriction allows the agent to access any path on your system. Use with caution in controlled environments only.

TakoBull can be deployed using Docker for consistent environments:

# Build Docker image
docker build -t takobull:latest .

# Run with configuration
docker run -v ~/.takobull:/root/.takobull takobull:latest agent -m "What is 2+2?"

# Run gateway for channel integrations
docker run -v ~/.takobull:/root/.takobull -p 18790:18790 takobull:latest gateway

# Build in debug mode (faster compilation)
cargo build

# Run tests
cargo test

# Run tests with output
cargo test -- --nocapture

# Run property-based tests
cargo test --test '*' -- --nocapture

# Watch for changes and rebuild (requires cargo-watch)
cargo watch -x build

All 39 tasks completed across 6 phases:

• Phase 1: Core Infrastructure ✅
• Phase 2: Authentication & Agent Loop ✅
• Phase 3: Channel Integrations ✅
• Phase 4: LLM Providers ✅
• Phase 5: Tools System ✅
• Phase 6: Integration & Optimization ✅

47 tests passing with zero failures. See CHANGELOG.md for detailed implementation notes.

Make sure your ~/.takobull/config.yaml has the correct API key for your chosen provider:

providers:
  openai:
    api_key: "your-actual-key-here"

This is normal if you haven't configured a search API key yet. TakoBull will automatically fall back to DuckDuckGo.

To enable Brave Search:

1. Get a free API key at https://brave.com/search/api (2000 free queries/month)
2. Add to ~/.takobull/config.yaml:

tools:
  web:
    brave:
      enabled: true
      api_key: "YOUR_BRAVE_API_KEY"
      max_results: 5

Make sure ~/.cargo/bin is in your PATH:

export PATH="$HOME/.cargo/bin:$PATH"

Add this to your shell profile (~/.bashrc, ~/.zshrc, etc.) to make it permanent.
