Task Watcher Skill

Monitor async tasks by polling their state and send Discord/Telegram notifications on changes or completion for workflows like CI/CD, deployments, or reviews.

task-watcher — Async Task Monitoring & Callback

Version: 1.2.0
Author: sly (OpenClaw)
License: MIT
Install: clawhub install task-watcher

Monitor long-running async tasks (content review, CI/CD, deployments) and get Discord/Telegram notifications when states change.

What It Does

Register tasks → Watcher polls for state changes → Sends notifications on change/completion.

Perfect for:

• Content publishing: Monitor XHS/社媒 review status after posting
• CI/CD: Track GitHub PR merges, build completions
• Deployments: Watch rollout status
• Any async workflow: Anything that takes time and you want to know when it's done

Architecture

Agent registers task → tasks.jsonl (shared-context)
                            ↓
Cron (*/3 * * * *) → watcher.py → Adapter checks state → state changed?
                                                              ↓ Yes
                                              Policy decides → Notifier sends Discord

Plugin architecture:

• Adapters: Pluggable state checkers. Built-in: XHS, GitHub PR, Cron Job
• Notifiers: Discord (via openclaw agent --deliver), Telegram, Session, File
• Policies: Notification frequency, escalation, retry logic
• Stores: JSONL-based persistence with file locking
• Protection: expires_at timeout (default 6h), 3x delivery failure escalation

Quick Start

1. Install

clawhub install task-watcher

2. Register a monitoring task

import sys, os
sys.path.insert(0, os.path.expanduser("~/.openclaw/workspace/skills/task-watcher/scripts/lib"))

from models import CallbackTask
from stores import JsonlTaskStore

store = JsonlTaskStore("~/.openclaw/shared-context/monitor-tasks/tasks.jsonl")
task = CallbackTask(
    task_id="tsk_my_task_001",
    owner_agent="content",
    target_system="xiaohongshu",
    target_object_id="note_id_here",
    reply_channel="discord",
    reply_to="channel:YOUR_CHANNEL_ID",
    current_state="submitted",
    expires_at="2026-03-08T12:00:00",  # 6h timeout recommended
)
store.create(task)

Or via CLI:

cd ~/.openclaw/workspace/skills/task-watcher
python3 scripts/register_task.py \
  --task-id tsk_my_001 \
  --system xiaohongshu \
  --object-id note_abc123 \
  --reply-to channel:1234567890 \
  --expires-hours 6

3. Run watcher (cron)

# Add to crontab - every 3 minutes
*/3 * * * * cd ~/.openclaw/workspace/skills/task-watcher && \
  python3 scripts/watcher.py --once >> ~/.openclaw/logs/watcher.log 2>&1

4. Custom adapter

from adapters import StateAdapter, StateResult

class MyAdapter(StateAdapter):
    @property
    def name(self): return "my-system"
    
    def supports(self, task): return task.target_system == "my-system"
    def health_check(self): return True
    
    def check(self, task):
        status = check_my_system(task.target_object_id)
        return StateResult(state=status, terminal=(status == "done"))
