chatmd 0.2.11

A local-first, text-driven personal AI Agent engine

ChatMarkdown

Your local-first AI agent, driven by text.

ChatMarkdown (CLI: chatmd) lets you interact with an AI Agent through Markdown files in any text editor. No need to leave your editor — type a command, save, and get AI answers, translations, file operations, and more.

Features

• Local-first — All data stored in local Markdown files, works offline
• Text-driven — Trigger via /command slash commands or @ai{} natural language
• Editor-agnostic — VS Code, Vim, Typora… any editor that can edit .md files
• Deterministic routing — Code-centric, not AI-centric; command execution is predictable
• Extensible — YAML declarative Skills + Python custom Skills + hot reload
• Secure — KernelGate injection prevention + confirmation window + audit log
• Git sync — Auto commit + pull/push, seamless multi-device collaboration

Quick Start

Step 0: Install Python (if needed)

ChatMarkdown requires Python 3.10 or later. Open a terminal and type python --version. If you see a version number (e.g. Python 3.12.x), skip to the next step.

Windows

1. Go to https://www.python.org/downloads/ and click Download Python 3.x.x
2. Run the installer — make sure to check ✅ "Add python.exe to PATH"
3. Close and reopen PowerShell or CMD
4. Verify: python --version

💡 You can also install Python from the Microsoft Store.

macOS

# Option 1: Download from https://www.python.org/downloads/

# Option 2: Homebrew (recommended if you have brew)
brew install python

Verify: python3 --version

💡 The built-in python3 on macOS may be outdated. Install the latest from python.org or Homebrew.

Linux (Ubuntu/Debian)

sudo apt update && sudo apt install python3 python3-pip python3-venv -y

Verify: python3 --version

Step 1: Install ChatMarkdown

Pick one of the following:

Option A: pipx (recommended — auto-isolated, hassle-free)

# Install pipx (one-time)
pip install pipx
pipx ensurepath
# ⚠️ Restart your terminal (close and reopen)

# Install chatmd
pipx install chatmd

💡 pipx creates an isolated environment for chatmd so it won't conflict with other Python packages.

Option B: pip + virtual environment (classic)

# Linux/macOS
python3 -m venv ~/.chatmd-env
source ~/.chatmd-env/bin/activate
pip install chatmd

# Windows
python -m venv %USERPROFILE%\.chatmd-env
%USERPROFILE%\.chatmd-env\Scripts\activate
pip install chatmd

💡 You need to activate the virtual environment each time before using chatmd.

Option C: Direct run (no PATH setup needed)

pip install chatmd
python -m chatmd --version

Verify installation:

chatmd --version

Step 2: Initialize a Workspace

chatmd init ~/my-workspace          # Linux/macOS
chatmd init %USERPROFILE%\my-workspace   # Windows

Step 3: Configure AI Provider (optional)

To use AI features like /ask and /translate, configure an API key in .chatmd/agent.yaml:

ai:
  providers:
    - name: litestartup
      type: litestartup
      api_url: https://api.litestartup.com/client/v2/ai/chat
      api_key: ${LITEAGENT_API_KEY}  # environment variable, or paste directly

Then set the environment variable:

export LITEAGENT_API_KEY="your-api-key"   # Linux/macOS
# set LITEAGENT_API_KEY=your-api-key      # Windows

💡 Local commands like /date and /help work without an AI provider.

Auto-save Editors (Obsidian, etc.)

If your editor auto-saves files, switch to suffix mode before starting the Agent:

chatmd mode suffix

In suffix mode, commands are only triggered when you end a line with ;:

/help;

/date;

/ask what is ChatMarkdown?;

To switch back: chatmd mode save

Step 4: Start the Agent

cd ~/my-workspace       # Linux/macOS
# cd %USERPROFILE%\my-workspace  # Windows

chatmd start            # foreground (Ctrl+C to stop)
# chatmd start --daemon # or run in background

Step 5: Start Interacting

Open chat.md in any editor, type a command, and save:

/help

/date

/ask What is ChatMarkdown?

@ai{Translate to Chinese: Hello World}

The Agent detects file changes, executes commands, and writes results back into the file.

Tool Invocation (LiteStartup)

Command	Description
/la <input>	Send a free-form request to LiteStartup; the agent picks the right tool (contact.create, email.send, blog.publish, …) and executes it.
/la confirm cft_<token>	Phase-2 confirmation for destructive tools (contact.delete, email.delete, blog.unpublish, …). LiteStartup returns a confirmation card with a cft_<32 hex> token; copy-paste the suggested command into the chat to actually execute. Tokens expire in 10 minutes; format is validated locally so a typo never reaches the network.

Trigger Methods

• Slash commands: /command input
• @ai{} inline: Please help me @ai{summarize this paragraph}
• @ai{} multi-line block:

  @ai{
  Translate the following:
  Hello World
  }
  

• Suffix signal: Summarize this for me; (enable in config)

Multi-Session Conversations

ChatMarkdown supports multiple independent conversation sessions. Each .md file maintains its own AI context:

• Default session — chat.md, for everyday Q&A
• Topic sessions — Create .md files under chat/, each file is an independent conversation

workspace/
├── chat.md              ← default conversation
└── chat/
    ├── project-plan.md  ← project planning
    ├── english-study.md ← English study
    └── _index.md        ← auto-maintained index (do not edit)

Each session's AI conversation history is saved independently and auto-restored on Agent restart. Use /list to see all sessions.

chatmd start [-w <workspace>]  # Start Agent (foreground)
