EJClaw

Dual-agent AI assistant (Claude Code + Codex) over Discord. Originally derived from qwibitai/nanoclaw.

Quick Context

Single unified service (ejclaw) manages three Discord bots (Claude, Codex-main, Codex-review) in one process. Owner/reviewer agent types are configurable via OWNER_AGENT_TYPE and REVIEWER_AGENT_TYPE in .env. Claude Code uses the Agent SDK; Codex uses the Codex SDK (codex exec). Auth via CLAUDE_CODE_OAUTH_TOKEN in .env (1-year token from claude setup-token).

Development

Run commands directly—don't tell the user to run them.

bun run build                              # Build main project
bun run build:runners                      # Install + build both runners
bun run build:container                    # Rebuild reviewer Docker image
bun run dev                                # Dev mode with hot reload

Service management (Linux):

systemctl --user restart ejclaw                   # Restart unified service
systemctl --user status ejclaw                    # Check status
journalctl --user -u ejclaw -f                    # Follow logs

Deploy:

bun run deploy

Service Stack Architecture

Single unified service manages all three Discord bots in one process:

• ejclaw.service — Single unified process
• Discord bots: DISCORD_BOT_TOKEN (Claude), DISCORD_CODEX_BOT_TOKEN (Codex-main), DISCORD_REVIEW_BOT_TOKEN (Codex-review)
• Paired review: owner (OWNER_AGENT_TYPE, default: codex) ↔ reviewer (REVIEWER_AGENT_TYPE, default: claude-code)
• Reviewer fallback: Claude 429/한도초과 시 codex-review로 자동 핸드오프
• Shared dirs: store/, groups/, data/
• SQLite WAL mode + busy_timeout=5000 for concurrent access

Debugging Paths

Unified DB + directories (both services share store/, groups/, data/):

항목	경로
DB	store/messages.db (공유, WAL 모드)
서비스 로그	journalctl --user -u ejclaw -f 또는 logs/ejclaw.log
그룹별 로그	groups/{name}/logs/ (공유 채널은 양쪽 봇 로그가 같은 폴더)
Claude 세션	data/sessions/{name}/.claude/
Codex 세션	data/sessions/{name}/.codex/
Claude 플랫폼 규칙	prompts/claude-platform.md
Codex 플랫폼 규칙	prompts/codex-platform.md
Claude 글로벌 메모리	groups/global/CLAUDE.md

Codex SDK

Codex runner uses @openai/codex-sdk (wraps codex exec):

• codex.startThread() / codex.resumeThread() for session persistence
• thread.run(input) for single-shot turn execution (completes all work before returning)
• approvalPolicy: "never" + sandboxMode: "danger-full-access" for bypass
• Per-group: model (CODEX_MODEL), effort (CODEX_EFFORT), MCP servers via config.toml
• CODEX_HOME set to per-group session dir, reads AGENTS.md from there + CWD

Voice Transcription

Audio attachments in Discord are transcribed via Groq Whisper (primary) or OpenAI Whisper (fallback):

• GROQ_API_KEY — Groq whisper-large-v3-turbo, ~200x real-time, free tier (console.groq.com)
• OPENAI_API_KEY — OpenAI whisper-1, fallback if Groq key not set
• Shared file cache (cache/transcriptions/) deduplicates across both services
• .pending file coordination prevents duplicate API calls
