Gateway Guardian — Skill Instructions

Triggers

Activate this skill when the user:

• Shares https://github.com/Dios-Man/gateway-guardian and asks to install it
• Says "install gateway-guardian", "帮我安装", "install this skill", or similar
• Says "gateway-guardian status", "guardian status", "guardian 运行正常吗", or similar
• Says "uninstall gateway-guardian", "卸载 gateway-guardian", or similar
• Sends a message matching 设置通知群: <id> or set guardian group: <id>

Installation (AI-executed)

Pre-flight checks

1. Confirm the system is Linux with systemd --user available:

   systemctl --user status 2>&1 | head -3

1. Check and install inotify-tools if missing:

   if ! which inotifywait > /dev/null 2>&1; then
       sudo apt-get install -y inotify-tools 2>/dev/null || apt-get install -y inotify-tools 2>/dev/null || true
   fi

If apt-get fails (no sudo), ask the user to run: sudo apt-get install -y inotify-tools

1. Confirm OpenClaw is installed and the gateway is running.

Determine notification fallback

Before writing guardian.conf, resolve the following values from the current conversation context:

FALLBACK_TARGET rules:

• Feishu: always user:{sender_id} (DM to installer, even if installed from a group)
• Telegram: use {chat_id} for direct chats; for groups, ask: "What is your personal Telegram numeric ID? (needed for DM notifications)"
• Discord: ask: "What is your Discord DM channel ID? (needed for direct notifications)"

These resolved values replace {detected channel} and {determined fallback target} in Step 4.

Determine notification language (LOCALE)

Detect the language the user is communicating in during this conversation:

• User is writing in Chinese → LOCALE=zh
• User is writing in English → LOCALE=en
• Language is unclear or mixed → ask the user: "Should notifications be sent in Chinese or English?"

Installation steps

Step 1 — Back up current config

TIMESTAMP_DIR="$HOME/.openclaw/config-backups"
mkdir -p "$TIMESTAMP_DIR"
cp "$HOME/.openclaw/openclaw.json" \
   "$TIMESTAMP_DIR/openclaw.json.$(date +%Y%m%d-%H%M%S).preinstall"
echo "Backup created: $(ls -t $TIMESTAMP_DIR | head -1)"

Step 2 — Download skill files

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
mkdir -p "$SKILL_DIR"
BASE_URL="https://raw.githubusercontent.com/Dios-Man/gateway-guardian/main"
for f in config-lib.sh config-watcher.sh gateway-recovery.sh pre-stop.sh; do
    # Skip if file already present (e.g. installed via clawhub install)
    [ -f "$SKILL_DIR/$f" ] && continue
    curl -fsSL "$BASE_URL/$f" -o "$SKILL_DIR/$f"
done

Step 3 — Ask bot name (optional)

Ask the user: "What name should I use for myself in team notifications? (e.g. Claw, MyBot, OpenClaw — press Enter to skip and use the default 'OpenClaw')"

Record as BOT_NAME. If the user skips, use OpenClaw.

Step 4 — Write guardian.conf

Substitute resolved values before running. Replace:

• {FALLBACK_CHANNEL} → resolved channel name (e.g. feishu)
• {FALLBACK_TARGET} → resolved target (e.g. user:ou_xxx for Feishu)
• {LOCALE} → zh or en
• {BOT_NAME} → bot display name from Step 3

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
cat > "$SKILL_DIR/guardian.conf" << GUARDIANCONF
# Auto-generated by gateway-guardian installer. Do not upload to GitHub.

# Fallback notification target (used when dynamic session detection fails)
FALLBACK_CHANNEL={FALLBACK_CHANNEL}
FALLBACK_TARGET={FALLBACK_TARGET}

# Notification language: zh (Chinese) | en (English)
LOCALE={LOCALE}

# Bot display name used in staff/team notifications
BOT_NAME={BOT_NAME}

# Team group/channel notification (optional)
# Leave empty to disable. Supported formats:
#   Feishu:   oc_xxx
#   Telegram: -100xxxxxxxxxx  (supergroup/channel numeric id)
#   Discord:  123456789012345678  (channel id, digits only)
# Only effective if the channel is configured and running in OpenClaw.
STAFF_GROUP_CHAT_ID=
GUARDIANCONF

Step 5 — Set execute permissions

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
chmod +x "$SKILL_DIR/config-watcher.sh"
chmod +x "$SKILL_DIR/gateway-recovery.sh"
chmod +x "$SKILL_DIR/pre-stop.sh"

Step 6 — Register config-watcher service

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
cat > ~/.config/systemd/user/openclaw-config-watcher.service << EOF
[Unit]
Description=OpenClaw Gateway Guardian - File Watcher
After=openclaw-gateway.service

[Service]
Type=simple
ExecStart=/bin/bash $SKILL_DIR/config-watcher.sh
Restart=always
RestartSec=3

[Install]
WantedBy=default.target
EOF

Step 7 — Register gateway-recovery service

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
cat > ~/.config/systemd/user/openclaw-recovery.service << EOF
[Unit]
Description=OpenClaw Gateway Guardian - Crash Recovery
After=network.target

[Service]
Type=oneshot
ExecStart=/bin/bash $SKILL_DIR/gateway-recovery.sh
EOF

Step 8 — Register OnFailure drop-in and ExecStopPost hook

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
mkdir -p ~/.config/systemd/user/openclaw-gateway.service.d/
cat > ~/.config/systemd/user/openclaw-gateway.service.d/recovery.conf << EOF
[Unit]
OnFailure=openclaw-recovery.service

[Service]
StartLimitBurst=3
StartLimitIntervalSec=60
ExecStopPost=/bin/bash $SKILL_DIR/pre-stop.sh
EOF

Step 9 — Start services

systemctl --user daemon-reload
systemctl --user enable openclaw-config-watcher.service
systemctl --user start openclaw-config-watcher.service

Step 10 — Verify installation

systemctl --user is-active openclaw-config-watcher.service
cat ~/.config/systemd/user/openclaw-gateway.service.d/recovery.conf
tail -5 /tmp/config-watcher.log

Step 11 — Report result to user

Reply with a summary in the user's language (match LOCALE):

✅ Gateway Guardian installed

🔔 Notification channel: {channel} (fallback target: {FALLBACK_TARGET}) 🌐 Notification language: {zh | en} 🤖 Bot name: {BOT_NAME} 📋 Service status: {Active line from systemctl output} 📝 Log: /tmp/config-watcher.log

To uninstall, tell me: "uninstall gateway-guardian" / "卸载 gateway-guardian"

Optional — Team group notification

If OpenClaw is used by multiple people, you can configure a group to receive recovery notifications.

zh prompt:

如果团队有多人使用，可以配置一个通知群，网关恢复后自动通知大家。 请发送以下消息完成配置（支持飞书 / Telegram / Discord）： 设置通知群: oc_xxx

en prompt:

If your team uses OpenClaw together, you can set up a group notification. When the gateway recovers, your team will be notified automatically. Send me this to configure (Feishu / Telegram / Discord supported): set guardian group: oc_xxx

When you receive the config command:

• Parse the group ID from the message
• Write it to STAFF_GROUP_CHAT_ID in guardian.conf
• Confirm back to the user

Status Check (AI-executed)

When the user asks for status:

systemctl --user status openclaw-config-watcher.service
tail -10 /tmp/config-watcher.log
ls -lt ~/.openclaw/config-backups/ | head -5

Report: service active/inactive, recent log lines, number of config backups on hand.

Set Team Group (AI-executed)

When the user sends a message matching 设置通知群: <id> or set guardian group: <id>:

1. Extract the group ID from the message
2. Determine the channel based on ID format:

- Starts with oc_ → feishu - Starts with -100 → telegram - Pure digits → discord

1. Update guardian.conf:

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
sed -i "s|^STAFF_GROUP_CHAT_ID=.*|STAFF_GROUP_CHAT_ID={extracted_id}|" "$SKILL_DIR/guardian.conf"

1. Confirm to the user (zh/en based on LOCALE):

- zh: ✅ 已配置团队通知群，网关恢复后会自动通知群里的成员。 - en: ✅ Team group configured. Members will be notified automatically when the gateway recovers.

Uninstall (AI-executed)

When the user asks to uninstall:

systemctl --user stop openclaw-config-watcher.service
systemctl --user disable openclaw-config-watcher.service
rm -f ~/.config/systemd/user/openclaw-config-watcher.service
rm -f ~/.config/systemd/user/openclaw-recovery.service
rm -f ~/.config/systemd/user/openclaw-gateway.service.d/recovery.conf
systemctl --user daemon-reload
systemctl --user reset-failed openclaw-gateway.service 2>/dev/null

Ask the user whether to also delete config backups:

# Only run if user confirms
rm -rf ~/.openclaw/config-backups/

Confirm removal is complete.

Notes

• This skill must be installed via an OpenClaw AI agent — no manual install script is provided.
• Installation requires an active message context (in-conversation metadata is used for notification setup).
• guardian.conf contains private notification config and is never uploaded to GitHub.
• Config backups in ~/.openclaw/config-backups/ are retained across uninstalls unless the user explicitly requests deletion.
• 群通知（_MSG_STAFF_RECOVERY）：配置了 STAFF_GROUP_CHAT_ID 则只发该固定群，未配置则动态检测最活跃 session 发送。
• 技术通知（urgent/status）：始终通过动态 session 检测发送，优先私聊，无私聊 session 时发最活跃群。guardian.conf 的 FALLBACK_CHANNEL/FALLBACK_TARGET 作为兜底。
