EJClaw

Dual-agent AI assistant (Claude Code + Codex) over Discord.

Originally derived from qwibitai/nanoclaw, now maintained as EJClaw for personal production use. Prompt design inspired by Q00/ouroboros, adapted for EJClaw's Discord and dual-service workflow.

Overview

Two AI agents running as parallel systemd services on a single host:

• Claude Code (@claude) — Anthropic Agent SDK, adaptive thinking, Opus/Sonnet
• Codex (@codex) — OpenAI Codex SDK (codex exec), GPT-5.4, xhigh reasoning

Both share the same codebase (dist/index.js), differentiated by environment variables. No containers — direct host processes for zero overhead.

Features

• Dual-agent architecture — Claude Code + Codex as parallel services, shared SQLite (WAL mode)
• Browser automation — gstack browse skill, headless Chromium daemon, ~100ms/command
• Voice transcription — Groq Whisper (primary) / OpenAI Whisper (fallback), shared file cache with dedup
• Bidirectional images — receive Discord attachments as multimodal input, send screenshots back
• Token rotation — Claude 429 / usage exhaustion → automatic multi-account rotation
• CI monitoring — watch_ci MCP tool for GitHub Actions run polling (structured fast path, no LLM token cost)
• Usage dashboard — real-time token usage and service status overview
• MCP integration — Memento (persistent memory) + EJClaw host tools (send_message, schedule_task, watch_ci, etc.)
• Skill sync — single source of truth, auto-synced to all agent sessions
• Priority queue — per-group serialization, global concurrency limit
• Session persistence — resume conversations across restarts
• Scheduled tasks — cron/interval/once via MCP tool
• Mid-turn steering — inject follow-up messages while agent is working (both agents)

Architecture

Discord ──► SQLite (WAL) ──► GroupQueue ──┬──► Claude Code (Agent SDK, MessageStream)
                                          └──► Codex (Codex SDK, codex exec)
                                          │
                                     IPC polling ◄── follow-up messages (mid-turn steering)
                                          │
                                     Router ──► Discord (text, images, files)

Each agent has access to:
  ├── MCP tools (send_message, schedule_task, watch_ci, ...)
  ├── Bash skills (agent-browser → gstack browse, persistent Chromium)
  └── Per-group memory (CLAUDE.md / AGENTS.md)

Setup

Prerequisites

• Linux (Ubuntu 22.04+) or macOS
• Node.js 20+ (24 recommended, fnm for version management)
• Claude Code CLI
• Codex CLI (npm install -g @openai/codex)
• Bun 1.0+ (for browser automation)
• Discord bot token

Install

git clone https://github.com/phj1081/EJClaw.git
cd EJClaw
npm install
npm run build:runners
npm run build

Environment

# .env
DISCORD_BOT_TOKEN=           # Discord bot token
ASSISTANT_NAME=claude        # Bot trigger name (@claude)
CLAUDE_CODE_OAUTH_TOKEN=     # Claude Code OAuth token (primary)
CLAUDE_CODE_OAUTH_TOKENS=    # Comma-separated tokens for multi-account rotation
OPENAI_API_KEY=              # For Codex
GROQ_API_KEY=                # Voice transcription (Groq Whisper)

Codex Service (optional)

To run the Codex agent alongside Claude, create .env.codex:

# .env.codex
DISCORD_BOT_TOKEN=               # Separate Discord bot token for Codex

# .env.codex-review
DISCORD_BOT_TOKEN=               # Separate Discord bot token for Codex Review

The setup step (npm run setup -- --step service) auto-detects .env.codex and .env.codex-review, then installs ejclaw-codex and ejclaw-review alongside ejclaw. Additional Codex settings (CODEX_MODEL, CODEX_EFFORT, etc.) can be added to .env.codex, .env.codex-review, or as Environment= lines in the systemd units.

Authentication

Multi-account OAuth token rotation is supported via CLAUDE_CODE_OAUTH_TOKENS (comma-separated). When one account hits a rate limit, the system automatically rotates to the next.

Token auto-refresh runs on the Claude service only, refreshing access tokens 30 minutes before expiry using rotating refresh tokens from ~/.claude/.credentials.json (account 0) and ~/.claude-accounts/{n}/.credentials.json (account 1+). Generate tokens with claude setup-token (account 0) or CLAUDE_CONFIG_DIR=~/.claude-accounts/{n} claude setup-token (account 1+).

Systemd Services (Linux)

npm run restart:stack
systemctl --user enable ejclaw ejclaw-codex ejclaw-review
systemctl --user start ejclaw ejclaw-codex ejclaw-review

# Logs
journalctl --user -u ejclaw -f

Development

npm run build                # Build main project
npm run build:runners        # Install + build both runners
npm run dev                  # Dev mode with hot reload
npm test                     # Run tests
