skillbot

An agentic bot powered by skills. Skillbot uses an LLM as its brain and Agent Skills as extensible capabilities, communicating via the A2A protocol.

Architecture

Skillbot follows a structured agent loop:

START -> Find Relevant Skills -> Load Skills -> Load Memories
      -> Plan & Execute -> Reflect -> [Complete?]
          -> Yes: Create Memories -> END
          -> No:  Summarize -> loop back to Find Skills

The loop is implemented as a LangGraph StateGraph with persistent checkpointing via SQLite.

Local Development

Prerequisites

• Python >= 3.13
• uv

Setup

Clone the repository and install dependencies:

git clone https://github.com/MadaraUchiha-314/skillbot.git
cd skillbot
uv sync --dev

This creates a .venv virtual environment and installs all runtime and dev dependencies.

Installing Pre-commit Hooks

Pre-commit hooks run linting, type checking, unit tests, and commit message validation automatically on every commit. Install them with:

uv run pre-commit install
uv run pre-commit install --hook-type commit-msg

You can also run all hooks manually against the entire codebase:

uv run pre-commit run --all-files

Common Commands

# Run unit tests
uv run pytest

# Run linter
uv run ruff check .

# Auto-fix lint issues
uv run ruff check . --fix

# Format code
uv run ruff format .

# Run type checker
uv run mypy skillbot

# Run all pre-commit hooks
uv run pre-commit run --all-files

Commit Messages

This project follows Conventional Commits. Commit messages are validated by Commitizen via a commit-msg hook. Use the format:

<type>(<optional scope>): <description>

[optional body]

[optional footer]

Examples:

feat: add user authentication
fix(parser): handle empty input gracefully
docs: update README with setup instructions

Running the CLI Locally

During development, use uv run to invoke the CLI. This uses the editable install from .venv so your local code changes are reflected immediately without reinstalling.

# Show available commands
uv run skillbot --help

# Initialize config in a local directory (avoids writing to ~/.skillbot)
uv run skillbot init --root-dir ./local-config

# Edit ./local-config/skillbot.config.json to add your OpenAI API key

# Start the agent server
uv run skillbot start --config ./local-config/skillbot.config.json

# In another terminal, start chatting
uv run skillbot chat --user-id my-user --config ./local-config/skillbot.config.json

If you prefer, you can also activate the virtualenv and run skillbot directly:

source .venv/bin/activate
skillbot --help

Hot-Reload (Development)

Use the --reload flag to automatically restart the server whenever you change code under skillbot/. This is the recommended way to run during development:

uv run skillbot start --config ./local-config/skillbot.config.json --reload

The server watches the skillbot/ directory for file changes and restarts automatically, so you don't need to manually stop and restart after each edit.
