add-update-check - SKILL.md Agent Skill

name: add-update-check description: Monthly check for GhostClaw updates. Notifies the user when new commits are available. Never auto-updates — user reviews and applies manually.

Add Update Check

Registers a monthly scheduled task that checks the GhostClaw repo for new commits and notifies the user if updates are available.

Setup

Find the main group's chat JID:

sqlite3 store/messages.db "SELECT jid FROM registered_groups WHERE folder = 'main' LIMIT 1;"

CHAT_JID="<main chat JID>"
cat > data/ipc/main/tasks/update_check_$(date +%s).json << EOF
{
  "type": "schedule_task",
  "prompt": "Check for GhostClaw updates.\n\n1. Run: git fetch origin 2>&1\n2. Run: git log HEAD..origin/main --oneline\n3. If there are new commits, message the user with how many and a one-line summary of each.\n4. If no new commits, respond with <internal>GhostClaw is up to date</internal> and nothing else.\n\nWhen notifying about updates, always include:\n- Number of new commits\n- One-line summary of each\n- Remind them: 'Review the changes with git diff HEAD..origin/main — then run /update-ghostclaw in Claude Code to apply safely (it backs up, migrates, rebuilds, and restarts).'\n- Remind them to review for security — this code runs with full system access.",
  "schedule_type": "cron",
  "schedule_value": "0 10 * * 1",
  "context_mode": "isolated",
  "targetJid": "$CHAT_JID"
}
EOF

This runs at 10am on the every Monday.

What the user sees

If updates are available:

3 new GhostClaw commits available:

abc1234 Add heartbeat disk usage threshold config

def5678 Fix Telegram reconnection on network change

ghi9012 Update Grammy to 1.25

Review the changes before applying. This code runs with full system access. Run git diff HEAD..origin/main to see the full diff. When ready, run /update-ghostclaw in Claude Code to apply safely.

If up to date: silence (wrapped in <internal> tags).

Security note

This skill deliberately does NOT auto-update. The user must:

Review the diff
Understand what changed
Run /update-ghostclaw to apply safely (or apply manually)

GhostClaw runs bare metal with no sandboxing. Blindly pulling code is a security risk.
