Gateway Guardian

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

Installation (AI-executed)

Pre-flight checks

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

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

2. Check and install inotify-tools if missing:

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

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

Determine notification fallback

Read from the current inbound message metadata:

• channel: messaging platform (feishu / telegram / discord / etc.)
• chat_type: conversation type (direct / group)
• sender_id

Set FALLBACK_TARGET (used when dynamic session detection fails):

• Feishu: user:{sender_id} — always send a DM, even if installed from a group
• Telegram: use chat_id for DMs; for groups, ask the user for their personal numeric Telegram ID
• Discord: ask the user for their DM channel ID

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 — Write guardian.conf

SKILL_DIR="$HOME/.openclaw/workspace/skills/gateway-guardian"
cat > "$SKILL_DIR/guardian.conf" << EOF
FALLBACK_CHANNEL={detected channel}
FALLBACK_TARGET={determined fallback target}
LOCALE={zh or en}
EOF

Step 4 — 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 5 — 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 6 — 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 7 — 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]

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

Step 8 — Start services

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

Step 9 — 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 10 — 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} 📋 Service status: {Active line from systemctl output} 📝 Log: /tmp/config-watcher.log

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

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.

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.
• Notifications use dynamic session detection at runtime; guardian.conf is only a fallback.
