name: memory-tiering description: Automated multi-tiered memory management (HOT, WARM, COLD). Use this skill to organize, prune, and archive context during memory operations or compactions.

Memory Tiering Skill 🧠⚖️

This skill implements a dynamic, three-tiered memory architecture to optimize context usage and retrieval efficiency.

The Three Tiers

1. 🔥 HOT (memory/hot/HOT_MEMORY.md):
   • Focus: Current session context, active tasks, temporary credentials, immediate goals.
   • Management: Updated frequently. Pruned aggressively once tasks are completed.
2. 🌡️ WARM (memory/warm/WARM_MEMORY.md):
   • Focus: User preferences (Hui's style, timezone), core system inventory, stable configurations, recurring interests.
   • Management: Updated when preferences change or new stable tools are added.
3. ❄️ COLD (MEMORY.md):
   • Focus: Long-term archive, historical decisions, project milestones, distilled lessons.
   • Management: Updated during archival phases. Detail is replaced by summaries.

Workflow: Organize-Memory

Whenever a memory reorganization is triggered (manual or post-compaction), follow these steps:

Step 1: Ingest & Audit

• Read all three tiers and recent daily logs (memory/YYYY-MM-DD.md).
• Identify "Dead Context" (completed tasks, resolved bugs).

Step 2: Tier Redistribution

• Move to HOT: Anything requiring immediate attention in the next 2-3 turns.
• Move to WARM: New facts about the user or system that are permanent.
• Move to COLD: Completed high-level project summaries.

Step 3: Pruning & Summarization

• Remove granular details from COLD.
• Ensure credentials in HOT point to their root files rather than storing raw secrets (if possible).

Step 4: Verification

• Ensure no critical information was lost during the move.
• Verify that HOT is now small enough for efficient context use.

Usage Trigger

• Trigger manually with: "Run memory tiering" or "整理记忆层级".
• Trigger automatically after any /compact command.
