adk-coder

adk-coder is a powerful, agentic development tool built on the Google ADK (Agent Development Kit). It provides a terminal-based interface (TUI) for interacting with Gemini models that have direct access to your local filesystem and shell.

🌟 Inspiration

This project is inspired by several leading agentic coding tools:

• gemini-cli: For its clean architecture and focus on Google's Gemini models.
• Claude Code: For its robust, phase-based orchestration and multi-agent patterns.
• Nano-Claw: For its "Integrity-First" approach to code modification and file handling.

🚀 Key Features

• Interactive TUI: A rich, responsive chat interface built with Textual.
• Filesystem Tools: Built-in capabilities to ls, cat, grep, write, and edit files.
• Shell Integration: Execute bash commands with user-approved security guards.
• Skill System: Extensible via Markdown-based "Skills" that define custom instructions and tool usage. Includes high-level orchestration like feature-dev for guided software engineering.
• Multi-Agent Orchestration: Specialized sub-agents (code-explorer, code-architect, code-reviewer) can be launched to handle specific phases of a task without polluting the main conversation context.
• Persistent Sessions: Automatically remembers project context and chat history using SQLite.
• Security First: Granular permission modes (ask, auto, plan) to control tool execution.
• Project Awareness: Automatically maps workspace roots to unique IDs for isolated session management.

🛠️ How It Works

adk-coder leverages Google ADK to orchestrate the agentic loop.

1. Orchestration: Uses the Runner and LlmAgent from ADK to manage the conversation flow and tool execution.
2. Policy Engine: A custom security plugin intercepts every tool call, checking it against a policy (e.g., read-only tools are allowed, while bash or write_file require a UI confirmation).
3. Context Management: It detects the project root (via .git, pyproject.toml, etc.) and manages history in a global SQLite database at ~/.adk/.

🚥 Getting Started

Prerequisites

• Python 3.14+
• A Gemini API Key from Google AI Studio.

Installation

# Clone the repository
git clone https://github.com/your-repo/adk-coder.git
cd adk-coder

# Install dependencies (using uv is recommended)
uv sync

Configuration

Set your API key in a .env file or export it:

export GOOGLE_API_KEY="your_api_key_here"

Usage

Launch the interactive TUI:

adk-coder

Execute a one-off task:

adk-coder chat "Review the current directory and list all python files" --print

Manage global settings:

adk-coder config set default_model gemini-3-flash-preview

🏗️ Development

This project uses a "Scripts to Rule Them All" pattern for development tasks:

• ./script/bootstrap: Install dependencies and set up the environment.
• ./script/test: Run the test suite (pytest).
• ./script/lint: Run linting checks (ruff).
