# Agent 记忆系统详细部署计划 (2026-02-25 · v5.0 OpenRouter + pgvector)
|
||||
|
||||
> **部署要求**：本计划使用本地 PostgreSQL/pgvector 存储向量，使用 OpenRouter 生成 embedding。无需 Ollama。
|
||||
|
||||
---
|
||||
|
||||
## 1. 基础环境与配置初始化
|
||||
|
||||
### 1.1 Python 环境（uv）
|
||||
确保本机已安装 `uv`，然后在 Vault 根目录执行：
|
||||
```bash
|
||||
uv sync --project .scripts/memory
|
||||
```
|
||||
|
||||
依赖由 `.scripts/memory/pyproject.toml` 管理，不再手动维护 venv。
|
||||
|
||||
### 1.2 PostgreSQL + pgvector
|
||||
|
||||
使用 Docker 启动（已安装 Docker 时）：
|
||||
```bash
|
||||
docker run --name pgvector-memory \
|
||||
-e POSTGRES_PASSWORD=postgres \
|
||||
-e POSTGRES_DB=memory \
|
||||
-p 5432:5432 \
|
||||
-d pgvector/pgvector:pg16
|
||||
```
|
||||
|
||||
初始化数据库：
|
||||
```sql
|
||||
CREATE EXTENSION IF NOT EXISTS vector;
|
||||
|
||||
CREATE TABLE IF NOT EXISTS memory_primary (
|
||||
id TEXT PRIMARY KEY,
|
||||
source TEXT NOT NULL,
|
||||
content TEXT NOT NULL,
|
||||
content_hash TEXT NOT NULL,
|
||||
embedding VECTOR(1536) NOT NULL,
|
||||
updated_at TIMESTAMPTZ NOT NULL DEFAULT now()
|
||||
);
|
||||
|
||||
CREATE TABLE IF NOT EXISTS memory_secure_audit (
|
||||
id TEXT PRIMARY KEY,
|
||||
source TEXT NOT NULL,
|
||||
risk TEXT NOT NULL,
|
||||
updated_at TIMESTAMPTZ NOT NULL DEFAULT now()
|
||||
);
|
||||
|
||||
CREATE INDEX IF NOT EXISTS memory_primary_embedding_idx
|
||||
ON memory_primary USING ivfflat (embedding vector_cosine_ops) WITH (lists = 100);
|
||||
```
|
||||
|
||||
### 1.3 `.gitignore` 与 `.env.memory`
|
||||
|
||||
`.gitignore` 追加：
|
||||
```gitignore
|
||||
.env.memory
|
||||
memory_eval/results/
|
||||
.memory-sync.log
|
||||
```
|
||||
|
||||
创建 `.env.memory`：
|
||||
```ini
|
||||
VAULT_DIR=/Users/windy/Documents/vault/my-vault
|
||||
|
||||
# PostgreSQL 连接串
|
||||
PG_DSN=postgresql://postgres:postgres@localhost:5432/memory
|
||||
|
||||
# OpenRouter
|
||||
OPENROUTER_API_KEY=your_key_here
|
||||
OPENROUTER_BASE_URL=https://openrouter.ai/api/v1
|
||||
OPENROUTER_EMBED_MODEL=openai/text-embedding-3-small
|
||||
OPENROUTER_EMBED_DIM=1536
|
||||
|
||||
# 索引锁
|
||||
INDEX_LOCK_FILE=/Users/windy/Documents/vault/my-vault/.memory-index.lock
|
||||
```
|
||||

## 2. 共享组件
|
||||

### 4.1 查询脚本 `.scripts/memory/query_pgvector.py`

## 5. 零阻塞 Git Hook
|
||||
|
||||
编辑 `.git/hooks/post-commit`：
|
||||
```bash
|
||||
# --- memory async index hook begin ---
|
||||
run_memory_async_index() {
|
||||
local vault_dir changes_file log_file
|
||||
vault_dir="$(git rev-parse --show-toplevel 2>/dev/null || true)"
|
||||
[[ -n "$vault_dir" ]] || return 0
|
||||
|
||||
log_file="$vault_dir/.memory-sync.log"
|
||||
changes_file="$vault_dir/.memory-changes-$(date +%s)-$$.txt"
|
||||
|
||||
git diff-tree --no-commit-id --name-status -r -M --diff-filter=ACDMRT HEAD -- '*.md' > "$changes_file" 2>/dev/null || true
|
||||
[[ -s "$changes_file" ]] || { rm -f "$changes_file"; return 0; }
|
||||
|
||||
nohup uv run --project "$vault_dir/.scripts/memory" python "$vault_dir/.scripts/memory/incremental_ingest.py" \
|
||||
--changes-file "$changes_file" >> "$log_file" 2>&1 &
|
||||
}
|
||||
run_memory_async_index
|
||||
# --- memory async index hook end ---
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. 验收步骤
|
||||
|
||||
1. **数据库连通性**：能连上 `PG_DSN` 并查询 `SELECT 1`。
|
||||
2. **OpenRouter 连通性**：小文本 embedding 请求返回 1536 维向量。
|
||||
3. **首次全量索引**：运行 `uv run --project .scripts/memory python .scripts/memory/ingest_vault.py` 无报错。
|
||||
4. **增量一致性**：重命名/删除后日志可见处理记录，旧路径不再召回。
|
||||
5. **隔离验证**：加入高危片段后仅进入 `memory_secure_audit`。
|
||||
6. **检索验证**：执行 `bash .scripts/memory/agent-with-memory.sh "xxx"` 能返回带来源的上下文。
|
||||
7. **指标验证**：基于固定 `queries.jsonl` 统计 Recall@5、P50/P95 延迟。

|
||||
|
||||
#### T7.1 无记忆模式回滚
|
||||
- 步骤：
|
||||
1. 移除 `.git/hooks/post-commit` 的 memory 片段。
|
||||
2. 停用 `agent-with-memory.sh`，改用普通 `claude`。
|
||||
3. 如需清库：
|
||||
```bash
|
||||
psql postgresql://postgres:postgres@localhost:5432/memory -c "TRUNCATE memory_primary, memory_secure_audit;"
|
||||
```
|
||||
- DoD：

|
||||
|
||||
## 3. 覆盖矩阵（方案/计划问题是否全部覆盖）
|
||||
|
||||
| 关键要求 | 来源 | 对应任务 | 是否覆盖 |

|
||||
| 冷启动 <= 4.5s | Strategy v5.0 | T6.3 | 是 |

# Agent 记忆系统选型与集成策略 (2026-02-25 · v5.0 OpenRouter + pgvector 本地库架构)
|
||||
|
||||
> **修订说明 (v5.0)**：将 A 层从 `ChromaDB + Ollama` 切换为 `OpenRouter Embedding API + 本地 PostgreSQL/pgvector`。目标是不运行本地 embedding 模型，同时保留本地向量存储与 Git 增量同步能力。
|
||||
|
||||
本方案面向基于 **PARA 架构** 的 Obsidian Vault，提供一套纯 Agent 驱动的记忆系统。系统不依赖 Obsidian 插件，通过 CLI 与大模型协作，解决 Agent "跨 Session 上下文连续性"和"复杂笔记语义召回"问题。
|
||||
|
||||
---
|
||||
|
||||
## 0. 设计目标与约束
|
||||
|
||||
1. **不使用本地 embedding 模型**：避免本机常驻 Ollama。
|
||||
2. **本地持久化**：向量与元数据留在本地 PostgreSQL。
|
||||
3. **增量优先**：基于 Git 变更做文件级 `upsert/delete`。
|
||||
4. **强一致**：删除、重命名、隔离、降阈值时不允许幽灵向量残留。
|
||||
5. **安全可控**：敏感内容不入检索库；检索注入具备 Prompt 注入防护。
|
||||
|
||||
---
|
||||
|
||||
## 1. 核心架构：双层记忆模型
|
||||
|
||||
### A 层：文档语义记忆（OpenRouter + pgvector）
|
||||
- **Embedding 生成**：调用 OpenRouter Embedding API。
|
||||
- **向量存储与检索**：本地 PostgreSQL + `pgvector`。
|
||||
- **数据源**：`01_Projects`、`02_Areas`。
|
||||
- **排除目录**：`00_Inbox`、`04_Archive`、`Infrastructure`、`Home-Automation`。
|
||||
|
||||
### B 层：事实与偏好记忆（Claude Memory）
|
||||
- **来源**：动态读取 Claude Code `MEMORY.md`。
|
||||
- **用途**：补充用户偏好、约束、近期状态。
|
||||
|
||||
---
|
||||
|
||||
## 2. 组件职责
|
||||
|
||||
| 组件 | 职责 | 解决的问题 |
|
||||
|------|------|-----------|
|
||||
| OpenRouter Embedding API | 文本向量化 | 不在本地部署 embedding 模型 |
|
||||
| PostgreSQL + pgvector | 向量持久化与相似度检索 | 本地可控存储、低运维 |
|
||||
| Git post-commit Hook | 触发增量索引 | 避免全量重建 |
|
||||
| 黑名单与敏感扫描 | 安全隔离 | 防止凭据入库与注入 |
|
||||
| Claude MEMORY.md | 偏好/事实注入 | 保持跨 Session 连续性 |
|
||||
|
||||
---
|
||||
|
||||
## 3. 验收指标（MVP）
|
||||
|
||||
1. **Recall@5 >= 70%**（包含 `source`）。
|
||||
2. **post-commit 不阻塞**：索引后台异步执行。
|
||||
3. **单文件增量 P95 < 1s**（不含远端 API 网络抖动）。
|
||||
4. **端到端冷启动 <= 4.5s**（含 OpenRouter 请求）。
|
||||
5. **安全红线**：敏感目录与敏感内容不得写入 Primary 检索表。
|
||||
6. **一致性红线**：`delete/rename/quarantine/prune` 后旧 ID 必须删除。
|
||||
|
||||
---
|
||||
|
||||
## 4. 安全与一致性策略
|
||||
|
||||
1. **路径部位精确匹配**：按 `Path.parts` 做目录排除。
|
||||
2. **内容单命中隔离**：任一高危特征命中即隔离。
|
||||
3. **强一致删除**：增量事件中 `D/R` 先删旧 ID，再处理新路径。
|
||||
4. **单写者锁**：索引写操作串行化。
|
||||
5. **只读上下文注入**：检索结果包装为引用块，禁止当指令执行。
|
||||
6. **长度截断**：注入前全局 `max_chars=2500`。
|
||||
|
||||
---
|
||||
|
||||
## 5. 关键权衡
|
||||
|
||||
1. **优点**
|
||||
- 不跑本地模型，设备压力低。
|
||||
- 向量在本地 DB，数据控制力强。
|
||||
- 与现有 Git 工作流兼容。
|
||||
|
||||
2. **代价**
|
||||
- embedding 文本会发送到 OpenRouter（不是纯本地隐私）。
|
||||
- 受网络与 API 可用性影响。
|
||||
- 需配置 API key 与请求限流/重试策略。
