MonClaw: A Minimal OpenClaw Implementation Using OpenCode SDK
MonClaw is a new minimal implementation of OpenClaw functionality using the OpenCode SDK, offering developers a lightweight alternative for building AI-powered chat assistants.
Key Features
- Telegram adapter — Built with Grammy library for Telegram bot integration
- WhatsApp adapter — Uses Baileys library for WhatsApp connectivity
- Simple memory system — Single markdown file (MEMORY.md) loaded on every message
- Proactive memory updates — Via an OpenCode plugin tool (save_memory)
- Heartbeat task runner — Periodic checklist from heartbeat.md file
- Channel-level whitelist — With disk persistence for security
Auth Model
MonClaw reuses OpenCode existing auth mechanisms. The default path uses createOpencode() so the SDK starts and manages a local OpenCode server. Alternatively, you can set OPENCODE_SERVER_URL to connect to an already-running server.
Quick Start
The project requires Bun runtime. After cloning the repository and installing dependencies, you log in using the OpenCode CLI, configure environment variables (primarily TELEGRAM_BOT_TOKEN), and run the development server.
Available Commands
In Telegram/WhatsApp chat:
/remember— Force-save durable memory/pair— Add account to whitelist/new— Start a new shared session across all channels
The project is experimental and the author recommends exercising caution, especially with sensitive data.

read-once: A Claude Code Hook That Prevents Redundant File Reads
A developer built a PreToolUse hook called read-once that tracks files Claude Code has already read in a session, blocking re-reads of unchanged files and using diffs for changed files. The tool saves thousands of tokens per session by preventing Claude from repeatedly reading the same file content.
Local AI Agent Achieves Sub-Second STT and TTS Latency with Open-Source Servers
A developer achieved ~0.2s STT latency using Whisper large-v3-turbo with hybrid thread-managed GPU architecture and ~250ms TTS latency with Coqui-TTS optimized for low-latency synthesis. Both implementations are fully self-hosted and open-sourced.
