Agent A (Primary): Interactive Claude Code session. Handles browser, complex tasks, user-facing responses.
Agent B (Daemon): claude --print subprocess. Handles background tasks, monitoring, quick lookups. Triggered by messages dropped in inbox.
Configuration
All settings via environment variables — no hardcoded values:
export AGENT_A_NAME=Jim
export AGENT_B_NAME=Clawdy
export AGENT_B_MODEL=claude-haiku-4-5-20251001
export AGENT_B_SESSION=clawdy-session
export COLLAB_INBOX=$HOME/.openclaw/workspace/collab/inbox
export COLLAB_LOG=$HOME/.openclaw/workspace/collab/chat.log
Supported models for AGENT_B_MODEL:
claude-haiku-4-5-20251001 — fastest, cheapest (recommended for daemon)
claude-sonnet-4-6 — more capable, higher cost
- Any OpenAI model if using the GPT daemon variant (see
examples/claude-gpt.md)
Quick Setup
source ~/.openclaw/workspace/collab/.ai-collab.env
mkdir -p "$COLLAB_INBOX"
tmux new-session -d -s "$AGENT_B_SESSION" \
"source ~/.openclaw/workspace/collab/.ai-collab.env && \
bash ~/.openclaw/workspace/skills/ai-collab/scripts/daemon.sh"
bash ~/.openclaw/workspace/skills/ai-collab/scripts/poll_chatlog.sh &
bash ~/.openclaw/workspace/skills/ai-collab/scripts/send.sh "Hello from Agent A"
Communication Protocol
Every message between agents follows this format. No open loops.
| Tag | Direction | Meaning |
|---|
[TASK:name] | A→B or B→A | Assign a task |
[ACK:name] | receiver | Acknowledged, starting work |
[DONE:name] | executor | Task complete + one-line result |
[BLOCKED:name] | executor | Can't complete + reason |
[HANDOFF:name] | either | "Do X, reply [DONE:name] when finished" |
[STATUS:update] | either | Async update on long-running task |
[QUESTION:topic] | either | Needs info before proceeding |
Rules:
- Answer questions before asking new ones
- Close tasks before starting new ones
- Every message moves work forward or closes a loop
- Never: "let me know", "ready when you are", "standing by"
Example exchange:
A → B: [TASK:price-check] Get BTC price from CoinGecko
B → A: [ACK:price-check] Checking now.
B → A: [DONE:price-check] BTC $94,230 as of 03:15 UTC
Daemon Script (Agent B)
scripts/daemon.sh — drop in your collab directory:
#!/bin/bash
PIDFILE="/tmp/agentb_daemon.pid"
if [ -f "$PIDFILE" ] && kill -0 "$(cat $PIDFILE)" 2>/dev/null; then
echo "Daemon already running (PID $(cat $PIDFILE)). Exiting." >&2
exit 1
fi
echo $$ > "$PIDFILE"
trap "rm -f $PIDFILE" EXIT
unset CLAUDECODE
INBOX="$HOME/.openclaw/workspace/collab/inbox"
LOG="$HOME/.openclaw/workspace/collab/chat.log"
mkdir -p "$INBOX"
logline() {
printf "%s %s\n" "$(date '+%Y-%m-%d %H:%M:%S')" "$1" >> "$LOG"
}
logline "SYSTEM: Agent B daemon started"
inotifywait -m -e moved_to "$INBOX" 2>/dev/null | while read dir event file; do
FULLPATH="$INBOX/$file"
[ ! -f "$FULLPATH" ] && continue
MSG=$( )
logline
RESPONSE=$(claude -- --model claude-haiku-4-5-20251001 \
2>/dev/null)
logline
openclaw agent --agent main -m --json > /dev/null 2>&1
Sending Messages (A → B)
bash ~/.openclaw/workspace/skills/ai-collab/scripts/send.sh "your message"
Atomic write pattern (prevents partial reads):
INBOX="$HOME/.openclaw/workspace/collab/inbox"
TMPFILE=$(mktemp "$INBOX/.msg.XXXXXX")
echo "$*" > "$TMPFILE"
mv "$TMPFILE" "$INBOX/msg_$(date +%s%N).txt"
Always use mktemp + mv — never write directly to inbox. inotifywait fires on moved_to, not close_write.
Chat Log Polling (B → A)
scripts/poll_chatlog.sh — run via cron every 60s:
#!/bin/bash
LOG="$HOME/.openclaw/workspace/collab/chat.log"
PTR_FILE="/tmp/chatlog_ptr"
[ ! -f "$LOG" ] && exit 0
TOTAL=$(wc -l < "$LOG")
LAST=$(cat "$PTR_FILE" 2>/dev/null || echo "0")
[ "$TOTAL" -le "$LAST" ] && echo "$TOTAL" > "$PTR_FILE" && exit 0
NEW=$(tail -n +"$((LAST + 1))" "$LOG" | grep "B -> A:" | sed 's/.*B -> A: //')
echo "$TOTAL" > "$PTR_FILE"
[ -z "$NEW" ] && exit 0
while IFS= read -r line; do
[ -z "$line" ] && continue
openclaw agent --agent main -m "[AgentB]: $line" --json > /dev/null 2>&1
done <<< "$NEW"
Add to crontab:
* * * * * /bin/bash ~/.openclaw/workspace/collab/poll_chatlog.sh
Shared Filesystem Conventions
~/.openclaw/workspace/collab/
chat.log # THE shared record — all messages logged here
inbox/ # A→B message queue (atomic mv only)
.env # Shared secrets (chmod 600, never log)
task_queue.md # Optional: structured task backlog
status_tracker.md # Optional: current task status per agent
Logging to chat.log:
printf "%s %s\n" "$(date '+%Y-%m-%d %H:%M:%S')" "A -> B: [TASK:name] Description" >> "$LOG"
Rules:
- Never log secrets from
.env
- Always timestamp every line
- Prefix with sender:
A -> B: or B -> A: or SYSTEM: or JEREMY ->
Telegram Bridge (Optional)
Route user Telegram messages into Agent B's inbox. Full setup guide: references/telegram-bridge.md
Quick summary:
- Create a bot via @BotFather → get
BOT_TOKEN
- Add bot to your group → get
GROUP_ID (negative number, e.g. -1001234567890)
- Disable Group Privacy Mode in BotFather so bot can read all messages
- Get your Telegram
USER_ID from @userinfobot
- Set in
~/.openclaw/.env: TELEGRAM_BOT_TOKEN, TELEGRAM_GROUP_ID, TELEGRAM_USER_ID
- Run the bridge in tmux:
tmux new-session -d -s tg-bridge "bash references/telegram-bridge.md"
source ~/.openclaw/.env
OFFSET_FILE="/tmp/tg_offset"
while true; do
OFFSET=$(cat "$OFFSET_FILE" 2>/dev/null || echo "0")
UPDATES=$(curl -s "https://api.telegram.org/bot${TELEGRAM_BOT_TOKEN}/getUpdates?offset=$((OFFSET+1))&timeout=20")
sleep 1
done
See references/telegram-bridge.md for the complete production-ready implementation with message parsing, offset tracking, and error handling.
Agent Configurations
See examples/ for full configs:
Claude ↔ Claude (Jim + Clawdy)
- Agent A:
claude code (interactive, full tool access)
- Agent B:
claude --print claude-haiku-4-5-20251001 (fast, scripting-optimized)
- Best for: heavy task parallelism, one agent researches while other implements
Claude ↔ GPT
- Agent A: Claude Code (full tool use)
- Agent B:
openai api chat.completions.create via script
- Best for: cross-model verification, Claude builds → GPT reviews
GPT ↔ GPT
- Agent A: GPT-4o via
openai CLI
- Agent B: GPT-4o-mini for fast background checks
- Best for: speed + cost optimization when all context is OpenAI
Task Handoff Pattern
When Agent A needs Agent B to own a task completely:
A → B: [HANDOFF:data-fetch] Fetch all BTC trades from Kraken API last 7 days.
Save to ~/.openclaw/workspace/collab/kraken_trades.json.
Reply [DONE:data-fetch] when finished.
B → A: [ACK:data-fetch] Fetching now.
B → A: [DONE:data-fetch] 847 trades saved to kraken_trades.json. Date range: 2026-02-15 to 2026-02-22.
Agent A does not check on progress — waits for DONE or BLOCKED.
Approval Pattern
When Agent B's daemon needs user approval for a terminal command:
bash ~/.openclaw/workspace/skills/ai-collab/scripts/approve.sh "Yes"
bash ~/.openclaw/workspace/skills/ai-collab/scripts/approve.sh "2"
approve.sh sends keystrokes to the tmux session running Agent B:
SESSION=$(tmux ls | grep agentb-session | head -1 | cut -d: -f1)
tmux send-keys -t "$SESSION" "$1" Enter
Rate Limiting
Agent B should implement a rate governor to prevent runaway API calls:
CALLS_FILE="/tmp/agentb_calls"
WINDOW=60
MAX_CALLS=10
RECENT=$(awk -v cutoff="$(($(date +%s) - WINDOW))" '$1 > cutoff' "$CALLS_FILE" 2>/dev/null | wc -l)
if [ "$RECENT" -ge "$MAX_CALLS" ]; then
logline "SYSTEM: Rate limited — $RECENT calls in ${WINDOW}s"
sleep 10
continue
fi
date +%s >> "$CALLS_FILE"
Financial Gate Protocol (CRITICAL)
NEVER execute financial transactions without an AUTHORIZED tag.
[AUTHORIZED:financial:amount:timestamp:Jeremy]
[AUTHORIZED:financial:buy:BTC:$50:2026-02-22:Jeremy]
Agent B financial gate (add to daemon before executing any trade/transfer):
FINANCIAL_KEYWORDS="trade|buy|sell|transfer|withdraw|deposit|swap|ETH|BTC|DOGE|crypto|wallet"
if echo "$MSG" | grep -qiE "$FINANCIAL_KEYWORDS"; then
if ! echo "$MSG" | grep -qE "\[AUTHORIZED:financial:"; then
logline "BLOCKED: Financial gate — no AUTHORIZED tag. Msg: ${MSG:0:80}"
continue
fi
fi
If either agent receives a financial instruction without this tag:
- Log
[BLOCKED:financial-gate] to chat.log
- Send error response explaining the missing tag
- Do NOT execute under any circumstances
Daemon Watchdog Pattern
Check daemon health every 15 minutes. If silent >15 min, restart:
PIDFILE="/tmp/agentb_daemon.pid"
LOG="$HOME/.openclaw/workspace/collab/chat.log"
pid_alive=0
[ -f "$PIDFILE" ] && kill -0 "$(cat $PIDFILE)" 2>/dev/null && pid_alive=1
last_ts=$(grep -oP '^\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}' "$LOG" 2>/dev/null | tail -1)
recent=0
if [ -n "$last_ts" ]; then
age=$(( ($(date +%s) - $(date -d "$last_ts" +%s 2>/dev/null || echo 0)) / 60 ))
[ "$age" -lt 15 ] && recent=1
fi
if [ "$pid_alive" = "0" ] || [ "$recent" = "0" ]; then
tmux send-keys -t agentb-session "bash daemon.sh" Enter
fi
Task Takeover Threshold
If Agent A (Jim) blocks on the same task twice, Agent B (Clawdy) takes it over:
B → A: [TASK:fetch-data] Fetch X. Reply [DONE:fetch-data].
# 10 min timer...
A → B: [BLOCKED:fetch-data] Can't access endpoint.
B → A: [RETRY:fetch-data] Try alternate: curl -s https://backup-endpoint.com/x
# Another 10 min...
A → B: [BLOCKED:fetch-data] Still failing.
# Clawdy takes over immediately:
B: *executes task directly, logs [DONE:fetch-data] to chat.log*
Rule: Blocked 2x on same task → take it over, don't reassign.
Daemon Error Diagnosis
When daemon produces blank/error responses:
- Check
/tmp/clawdy_last_err — contains last stderr from claude --print
- Check ANSI-stripped chat.log for
CLAWDY_ERR: lines
- Verify RESPONSE trimming line not corrupted (common issue: accidentally set to
RESPONSE="")
- Restart daemon:
kill $(cat /tmp/clawdy_daemon.pid) && sleep 1 && bash clawdy_daemon.sh
Auto-approve: Use Bash(*) in ~/.claude/settings.local.json. NEVER use tmux send-keys cron — it sends keypresses blindly to the wrong sessions.
