pythinker-ai 2.0.1

Pythinker — an ultra-lightweight personal AI agent framework with built-in chat channels, memory, MCP, and an OpenAI-compatible API.

🐍 Pythinker

🐍 Pythinker is an open-source, ultra-lightweight personal-AI-agent framework. It keeps the core agent loop small and readable while still supporting chat channels, long-term memory, MCP, and practical deployment paths — so you can go from local setup to a long-running personal agent with minimal overhead.

Powered by a small, multiplexing agent loop: one Python process listens to Slack, Telegram, Discord, WhatsApp, Matrix, MS Teams, email, a WebSocket WebUI, and an OpenAI-compatible HTTP API — all backed by a single session-scoped memory layer.

💡 Key Features

• Ultra-lightweight — a small readable core. Stable long-running behavior without orchestration sprawl.
• Channel-agnostic — Slack, Telegram, Discord, WhatsApp, Matrix, MS Teams, email, WebSocket, plus an OpenAI-compatible HTTP API.
• Full-screen TUI — pythinker tui (alias chat) opens a prompt_toolkit chat with live streaming, slash-command pickers (/model, /provider, /sessions, /theme, /help, /status), fuzzy search, themable chrome (default + monochrome), and Ctrl+C cancellation of in-flight turns.
• Provider-rich — 25+ LLM providers (Anthropic, OpenAI, Azure OpenAI, OpenAI Codex, GitHub Copilot, Qwen/DashScope, MiniMax, VolcEngine, Moonshot, DeepSeek, StepFun, and more) behind a single interface.
• Provider hot-reload — edits to model / provider / API key in ~/.pythinker/config.json land at the next turn boundary. No restart of the SDK or gateway. Same-signature snapshots short-circuit; broken configs are logged and swallowed so an in-flight session can't crash on a typo.
• Governed-execution runtime (off by default) — opt-in RuntimeConfig wires a PolicyService (allow-lists from agent manifests, per-turn budgets, recursion depth), a ToolEgressGateway chokepoint, an AgentRegistry directory loader, RequestContext + BudgetCounters plumbing, and a pluggable TelemetrySink (loguru / JSONL / composite). When the loader is None and policy is off, the runtime is bit-for-bit identical to the legacy path.
• Memory that learns — a two-phase "Dream" process consolidates long-term memory into MEMORY.md / SOUL.md / USER.md, auto-versioned with pure-Python git.
• Skills & MCP — bundled skills (GitHub, cron, weather, tmux, summarize, skill-creator, …) plus first-class Model Context Protocol tool access.
• Research-grade PDF reports — opt-in make_pdf tool renders structured Markdown to a styled PDF via ReportLab (pip install 'pythinker-ai[reports]').
• Sandboxed shell — every command is wrapped in a bubblewrap sandbox on Linux; file tools enforce workspace boundaries.
• Hackable — the Python package is ~58k LOC with zero monolithic orchestration layer. Read it, fork it, extend it.

📦 Install

Pythinker requires Python 3.11 or newer. Check your version with python3 --version. If yours is older, follow the per-OS steps below first.

1. Install Python 3.11+ (skip if you already have it)

macOS

# Recommended — Homebrew (https://brew.sh)
brew install python@3.13

# Or download an installer from python.org:
#   https://www.python.org/downloads/macos/
# After install, verify:
python3 --version    # should print 3.11 or newer

Linux

# Debian / Ubuntu
sudo apt update && sudo apt install -y python3.13 python3.13-venv python3-pip

# Fedora / RHEL / Rocky
sudo dnf install -y python3.13 python3-pip

# Arch
sudo pacman -S python python-pip

# Verify
python3 --version    # should print 3.11 or newer

If your distro's repos don't ship 3.11+, install pyenv or use the uv flow below — uv will fetch a managed Python automatically.

Windows

# Recommended — winget (built into Windows 10/11)
winget install Python.Python.3.13

# Or download an installer from python.org:
#   https://www.python.org/downloads/windows/
# At the bottom of the installer, tick "Add python.exe to PATH" before clicking Install.

# Verify (open a new PowerShell):
python --version    # should print 3.11 or newer

If python isn't found, restart your shell (or sign out / back in) so the new PATH takes effect.

2. Install Pythinker

uv tool install pythinker-ai

This installs Pythinker into an isolated environment and puts pythinker on your PATH. uv handles Python, PATH, and upgrades for you — and will fetch a managed Python 3.11+ if your system doesn't have one.

Don't have uv?

# macOS / Linux / WSL:
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell):
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

Restart your shell so the new PATH is picked up, then re-run uv tool install pythinker-ai.

Prefer pipx, plain pip, or source?

# pipx (equivalent to uv tool install, slower):
pipx install pythinker-ai

# Plain pip (last resort — you may need to add ~/.local/bin to PATH):
pip install --user pythinker-ai

# From source (contributors only):
git clone [e-mail]:mohamed-elkholy95/Pythinker-ai.git
cd Pythinker-ai && uv sync --all-extras

If pythinker isn't found after install, run pythinker doctor (via python -m pythinker doctor if needed) for diagnostics.

3. Optional extras

Pythinker ships small to keep the default install fast. Pull in the features you actually use:

uv tool install 'pythinker-ai[reports]'   # Markdown → PDF reports (research/report deliverables)
uv tool install 'pythinker-ai[matrix]'    # Matrix channel (E2E messaging)
uv tool install 'pythinker-ai[discord]'   # Discord channel
uv tool install 'pythinker-ai[msteams]'   # Microsoft Teams channel
uv tool install 'pythinker-ai[browser]'   # Headless browser tool (Playwright)
uv tool install 'pythinker-ai[pdf]'       # Read PDF files (PyMuPDF)
uv tool install 'pythinker-ai[api]'       # OpenAI-compatible HTTP server
# Combine: uv tool install 'pythinker-ai[reports,discord,browser]'

4. Install / pin a specific version

pythinker-ai follows SemVer — major-version upgrades are not auto-installed. To pin or to opt into a major bump, use the explicit pin form for your install method:

Goal	Command
Pin exactly 2.0.0 (uv tool — recommended)	uv tool install --reinstall "pythinker-ai==2.0.0"
Pin exactly 2.0.0 (pipx)	pipx install --force "pythinker-ai==2.0.0"
Pin exactly 2.0.0 (plain pip)	python -m pip install --force-reinstall "pythinker-ai==2.0.0"
Stay at the latest stable release	pythinker upgrade
From inside pythinker, target a specific version	pythinker update --target 2.0.0 -y

pip install -U pythinker-ai==2.0.0 works too, but it's semantically noisy: the exact pin controls the version, not -U. pythinker upgrade will refuse to cross a major version (e.g. 1.x → 2.x) without an explicit pythinker update --target opt-in.

🚀 Quick Start

pythinker onboard                           # write a config at ~/.pythinker/config.json
pythinker provider login openai-codex       # OAuth sign-in (the default provider)
pythinker agent                             # interactive CLI chat
pythinker tui                               # full-screen interactive chat (alias: chat)

pythinker onboard ships a config preconfigured for OpenAI Codex via ChatGPT OAuth (no API key needed). To use a different provider/model, edit ~/.pythinker/config.json — see Configuration for the full catalog of 25+ providers.

• Want different LLM providers, web search, MCP, security settings, or more config options? See Configuration.
• Want to run Pythinker in chat apps like Telegram, Discord, Slack, WhatsApp, or Matrix? See Chat Apps.
• Want Docker or Linux service deployment? See Deployment.
• Want governed-execution (policy allow-lists, budgets, telemetry) for hardened deployments? See Architecture §5.X — pythinker/runtime/. The layer is opt-in via runtime.policyEnabled in config.json.

🖥️ TUI

pythinker tui (alias pythinker chat) opens a full-screen prompt_toolkit interface for interactive sessions — a step up from pythinker agent's line-by-line REPL.

pythinker tui                               # opens with the default theme
pythinker tui --theme monochrome            # high-contrast / accessibility-friendly
pythinker tui --workspace ~/work/agent      # override per-session workspace
pythinker tui --logs ~/.pythinker/tui.log   # mirror loguru output to a file

Layout. A persistent chat pane (streamed assistant tokens render live with markdown swap-in once the turn ends), a status bar showing session/model/provider/iteration count, a hint footer for the current keymap, and a multiline editor with slash-command autocomplete.

Slash commands. Open in-app overlays for everything you'd normally configure on the CLI:

Command	Opens
/help	Built-in cheat sheet
/status	Live snapshot — session key, model, provider, message count, recent activity
/sessions	Fuzzy-pick from past sessions and resume
/model	Fuzzy-pick a model from the active provider
/provider	Switch LLM provider
/theme	Swap between default and monochrome themes (persisted to cli.tui.theme)
/mcp	Show MCP status — configured servers, connected servers, registered tools; /mcp reconnect reloads MCP config and reconnects
/clear	Clear the chat pane (/clear --hard also wipes session memory)
/exit	Quit

Pickers support fuzzy search — start typing to filter, ↑/↓ to navigate, Enter to commit, Esc to dismiss.

Keymap.

Key	Action
Enter	Submit message
Ctrl+J	Newline inside the editor
Ctrl+C	Cancel the in-flight turn (or quit when idle)
Esc	Close the active overlay / picker
↑ / ↓	Move cursor in pickers; PageUp / PageDown for 5-step jumps

Theming. Two themes ship by default. Set cli.tui.theme in ~/.pythinker/config.json or pass --theme. Both themes provide separate prompt_toolkit chrome styles and Rich content styles so the chat panel and the surrounding UI stay visually consistent.

🧪 WebUI (Development)

[!NOTE] The WebUI development workflow currently requires a source checkout and is not yet shipped together with the official packaged release. See the WebUI README for full WebUI development docs and build steps.

1. Enable the WebSocket channel in ~/.pythinker/config.json

{ "channels": { "websocket": { "enabled": true } } }

2. Start the gateway

pythinker gateway

3. Start the WebUI dev server

cd webui
bun install
bun run dev

🏗️ Architecture

🐍 Pythinker stays lightweight by centering everything around a small agent loop: messages come in from chat apps, the LLM decides when tools are needed, and memory or skills are pulled in only as context instead of becoming a heavy orchestration layer. That keeps the core path readable and easy to extend, while still letting you add channels, tools, memory, and deployment options without turning the system into a monolith.

See docs/ARCHITECTURE.md for a forensic walkthrough of the runtime.
