+# 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.
