Agentic Loops Pack

A scheduled agent without state is a cron job with a language model attached. It scans the same sources, scores the same items, and hands you the same briefing it handed you yesterday. The fix is not a better prompt — it is a state file the agent reads on the way in and writes on the way out.

This pack is five such patterns, each with the YAML template and the JSON state schema that goes with it: delta detection for market and price scanners, carry-forward for briefings and to-do agents, topic lifecycle for research scanners, signal evolution for trend tracking, and baseline diff for security and health checks.

CRON-INTEGRATION.md covers wiring state reads and writes into an agent prompt you already have. COLD-START.md covers the first run, when there is no history to read yet — the case most stateful designs forget about.

• Delta detection — compare today against yesterday, report only what changed
• Carry-forward — track items across runs and escalate anything stale for 3 days
• Topic lifecycle — new → tracking → ongoing → mature, auto-pruning at 7+ days
• Signal evolution and baseline diff — score histories, and new/resolved/changed/stable markers
