Screen Activity Tracker Lite

Minimal screen activity tracking. Trigger: track screen, start/stop tracking, daily summary, search history, 开始追踪屏幕, 屏幕活动总结, 整理今天的操作. Uses cron tool for tracking and bash for summary/search.

Zero-config screen activity tracking.

⚠️ CRITICAL: Tool Usage Rules

NEVER call skill_workshop tool. It will error. Only use:

User Intent	Tool	How
Start tracking	cron	{"operation":"add","name":"屏幕活动记录","command":"...","cron":"*/5 * * * *"}
Stop/Resume/List	cron	{"operation":"edit","jobId":"...","enabled":false} or {"operation":"list"}
Daily summary	bash	python3 <SKILL_DIR>/scripts/activity-analyzer.py summary
Search history	bash	python3 <SKILL_DIR>/scripts/activity-analyzer.py search "keyword"
