This skill covers memory architectures that balance context retention, token budget, and retrieval accuracy for agents that run for hours, days, or continuously.\n\n---\n\n## Core Concepts\n\n### The Memory Problem\n\n| Issue | Symptom | Cost |\n|-------|---------|------|\n| **Context Overflow** | Agent forgets early instructions | Task failure, incoherent responses |\n| **Token Bloat** | Every message keeps growing | 10x+ cost increase per task |\n| **Memory Pollution** | Irrelevant memories distract agent | Hallucination, off-target responses |\n| **Stale Memories** | Outdated information used as fact | Incorrect decisions |\n| **Memory Leaks** | Unused data accumulates unbounded | Crash from OOM, endless context |\n\n### Memory Tiers\n\n| Tier | Storage | Capacity | Access Speed | Cost | Best For |\n|------|---------|----------|-------------|------|----------|\n| **L1 — Working** | In-context (LLM window) | 8K-200K tokens | Instant | $$$ | Current task, immediate context |\n| **L2 — Recent** | Sliding window buffer | ~2K turns | < 10ms | $$ | Recent conversation history |\n| **L3 — Episodic** | Event log / timeseries | Millions of events | < 50ms | $ | Past actions, outcomes, decisions |\n| **L4 — Semantic** | Vector database | Unlimited | < 100ms | $ | Knowledge, facts, relationships |\n| **L5 — Archival** | Object storage | Unlimited | > 1s | $ | Backups, compliance, audit |\n\n---\n\n## Step-by-Step Implementation\n\n### Step 1: Build a Tiered Memory System\n\n```python\nfrom dataclasses import dataclass, field\nfrom typing import Optional\nimport json\nimport time\n\n@dataclass\nclass MemoryEntry:\n    content: str\n    timestamp: float = None\n    importance: float = 0.5  # 0.0 (trivial) to 1.0 (critical)\n    tags: list[str] = field(default_factory=list)\n    token_count: int = 0\n    \n    def __post_init__(self):\n        if self.timestamp is None:\n            self.timestamp = time.time()\n\nclass TieredMemory:\n    \"\"\"Multi-tier memory with automatic promotion and demotion.\"\"\"\n    \n    def __init__(self, llm, vector_store, max_context_tokens: int = 8000):\n        self.llm = llm\n        self.vector_store = vector_store\n        self.max_context_tokens = max_context_tokens\n        \n        # L1: Working context (in-memory)\n        self.working_memory: list[MemoryEntry] = []\n        self.current_tokens = 0\n        \n        # L2: Recent history buffer\n        self.recent_buffer: list[MemoryEntry] = []\n        self.buffer_size = 50\n        \n        # L3: Episodic memory\n        self.episodes: list[MemoryEntry] = []\n        \n        # L4: Semantic memory (vector DB)\n        # Initialized externally\n    \n    async def remember(self, content: str, importance: float = 0.5, \n                       tags: list[str] = None):\n        \"\"\"Store a new memory across tiers.\"\"\"\n        entry = MemoryEntry(\n            content=content,\n            importance=importance,\n            tags=tags or [],\n            token_count=self._count_tokens(content)\n        )\n        \n        # Always add to working memory\n        self.working_memory.append(entry)\n        self.current_tokens += entry.token_count\n        \n        # If important, store in episodic + semantic\n        if importance > 0.7:\n            self.episodes.append(entry)\n            await self.vector_store.store(entry)\n        \n        # Trim if needed\n        await self._trim_working_memory()\n```\n\n### Step 2: Implement Context Window Management\n\n```python\nclass ContextManager:\n    \"\"\"Optimize what stays in the context window.\"\"\"\n    \n    def __init__(self, tiered_memory: TieredMemory, \n                 summarizer, max_tokens: int = 8000):\n        self.memory = tiered_memory\n        self.summarizer = summarizer\n        self.max_tokens = max_tokens\n        self.reserved_tokens = 2000  # Reserve for new input/output\n    \n    async def build_context(self, task: str, top_k: int = 5) -> list[dict]:\n        \"\"\"Build the optimal context for a task.\"\"\"\n        \n        available_tokens = self.max_tokens - self.reserved_tokens\n        \n        # 1.
