> **Still using CLAUDE.md / MEMORY.md as memory?** This Markdown-file memory approach has fatal flaws: the file keeps growing, injecting everything into every session and burning massive tokens; content only supports keyword matching — search "database timeout" and you won't find "MySQL connection pool pitfall"; sharing one file across projects causes cross-contamination; there's no task tracking, so dev progress lives entirely in your head; not to mention the 200-line truncation, manual maintenance, and inability to deduplicate or merge.
>
> **AIVectorMemory is a fundamentally different approach.** Local vector database storage with semantic search for precise recall (matches even when wording differs), on-demand retrieval that loads only relevant memories (token usage drops 50%+), automatic multi-project isolation with zero interference, and built-in issue tracking + task management that lets AI fully automate your dev workflow. All data is permanently stored on your machine — zero cloud dependency, never lost when switching sessions or IDEs.

## ✨ Core Features

| Feature | Description |
|---------|-------------|
| 🧠 **Cross-Session Memory** | Your AI finally remembers your project — pitfalls, decisions, conventions all persist across sessions |
| 🔍 **Hybrid Smart Search** | FTS5 full-text + vector semantic dual-path search, RRF fusion ranking + composite scoring (recency × frequency × importance), far more precise than pure vector search |
| 🐛 **Issue Tracking** | Built-in Issue Tracker — discover → investigate → fix → archive, full lifecycle. AI manages bugs automatically |
| 📋 **Task Management** | Spec → task breakdown → nested subtasks → status sync → linked archival. AI drives the complete dev workflow |
| 🚦 **Session State** | Blocking management + breakpoint resume + progress tracking, seamless handoff across sessions and context compaction |
| 🪝 **Hooks + Steering** | Auto-inject workflow rules + behavior guard hooks, consistent AI behavior guaranteed — no need to repeat instructions |
| 🧬 **Memory Evolution** | Contradiction detection auto-supersedes stale knowledge + short-term → long-term auto-promotion + 90-day auto-archive, self-evolving memory |
| 📊 **Desktop App + Web Dashboard** | Native desktop app (macOS/Windows/Linux) + Web dashboard, 3D vector network reveals knowledge connections at a glance |
| 💰 **Save 50%+ Tokens** | Stop copy-pasting project context every conversation. Semantic retrieval on demand, no more bulk injection |
| 🏠 **Fully Local** | Zero cloud dependency. ONNX local inference, no API Key, data never leaves your machine |

## 🚀 Quick Start

### Option 1: pip install (Recommended)

```bash
# Install
pip install aivectormemory

# Upgrade to latest version
pip install --upgrade aivectormemory

# Navigate to your project directory, one-click IDE setup
cd /path/to/your/project
run install
```

`run install` interactively guides you to select your IDE, auto-generating MCP config, Steering rules, and Hooks — no manual setup needed.

> **macOS users note**:
> - If you get `externally-managed-environment` error, add `--break-system-packages`
> - If you get `enable_load_extension` error, your Python doesn't support SQLite extension loading (macOS built-in Python and python.org installers don't support it). Use Homebrew Python instead:
>   ```bash
>   brew install python
>   /opt/homebrew/bin/python3 -m pip install aivectormemory
>   ```

### Option 2: uvx (zero install)

No `pip install` needed, run directly:

```bash
cd /path/to/your/project
uvx aivectormemory install
```

> Requires [uv](https://docs.astral.sh/uv/getting-started/installation/) to be installed. `uvx` auto-downloads and runs the package — no manual installation needed.

### Option 3: Manual configuration

```json
{
  "mcpServers": {
    "aivectormemory": {
      "command": "run",
      "args": ["--project-dir", "/path/to/your/project"]
    }
  }
}
```

<details>
<summary>📍 IDE Configuration File Locations</summary>

| IDE | Config Path |
|-----|------------|
| Kiro | `.kiro/settings/mcp.json` |
| Cursor | `.cursor/mcp.json` |
| Claude Code | `.mcp.json` |
| Windsurf | `.windsurf/mcp.json` |
| VSCode | `.vscode/mcp.json` |
| Trae | `.trae/mcp.json` |
| OpenCode | `opencode.json` |
| Codex | `.codex/config.toml` |

</details>

For Codex, use project-scoped TOML instead of JSON:

```toml
[mcp_servers.aivectormemory]
command = "run"
args = ["--project-dir", "/path/to/your/project"]
```

> Codex only loads project-scoped `.codex/config.toml` after the repository is marked as a trusted project.

## ⚡ Pairing with Steering Rules

AIVectorMemory is the storage layer. Use Steering rules to tell AI **when and how** to call these tools.

Running `run install` auto-generates Steering rules and Hooks config — no manual setup needed.

| IDE | Steering Location | Hooks |
|-----|------------------|-------|
| Kiro | `.kiro/steering/aivectormemory.md` | `.kiro/hooks/*.hook` |
| Cursor | `.cursor/rules/aivectormemory.md` | `.cursor/hooks.json` |
| Claude Code | `CLAUDE.md` (appended) | `.claude/settings.json` |
| Windsurf | `.windsurf/rules/aivectormemory.md` | `.windsurf/hooks.json` |
| VSCode | `.github/copilot-instructions.md` (appended) | `.claude/settings.json` |
| Trae | `.trae/rules/aivectormemory.md` | — |
| OpenCode | `AGENTS.md` (appended) | `.opencode/plugins/*.js` |
| Codex | `AGENTS.md` (appended) | — |

<details>
<summary>📋 Steering Rules Example (auto-generated)</summary>

```markdown
# AIVectorMemory - Workflow Rules

## 1. New Session Startup (execute in order)

1. `recall` (tags: ["project-knowledge"], scope: "project", top_k: 100) load project knowledge
2. `recall` (tags: ["preference"], scope: "user", top_k: 20) load user preferences
3. `status` (no state param) read session state
4. Blocked → report and wait; Not blocked → enter processing flow

## 2. Message Processing Flow

- Step A: `status` read state, wait if blocked
- Step B: Classify message type (chat/correction/preference/code issue)
- Step C: `track create` record issue
- Step D: Investigate (`recall` pitfalls + read code + find root cause)
- Step E: Present plan to user, set blocked awaiting confirmation
- Step F: Modify code (`recall` pitfalls before changes)
- Step G: Run tests to verify
- Step H: Set blocked awaiting user verification
- Step I: User confirms → `track archive` + clear block

## 3. Blocking Rules

Must `status({ is_blocked: true })` when proposing plans or awaiting verification.
Only clear after explicit user confirmation. Never self-clear.

## 4-9. Issue Tracking / Code Checks / Spec Task Mgmt / Memory Quality / Tool Reference / Dev Standards

(Full rules auto-generated by `run install`)
```

<details>
<summary>🔗 Hooks Config Example (Kiro only, auto-generated)</summary>

Auto-save on session end removed. Dev workflow check (`.kiro/hooks/dev-workflow-check.kiro.hook`):

```json
{
  "enabled": true,
  "name": "Dev Workflow Check",
  "version": "1",
  "when": { "type": "promptSubmit" },
  "then": {
    "type": "askAgent",

## 🇨🇳 Users in China

The embedding model (~200MB) is auto-downloaded on first run. If slow:

```bash
export HF_ENDPOINT=https://hf-mirror.com
```

Or add env to MCP config:

```json
{
  "env": { "HF_ENDPOINT": "https://hf-mirror.com" }
}
```

## 📋 Changelog

### v2.4.5

**Patch: Hard Constraints Against Opus 4.7 Default Tendencies**

- 🚫 §1 added **No Clarification-Style Follow-ups**: forbid re-asking "phased or one-shot / full or partial / should I do X / do A first or B first" for imperative commands; under ambiguity, execute the most complete scope
- 🚫 §1 added **No Defensive Reporting**: forbid wording like "kept per instruction / marked pending / non-critical path / unnecessary sub-tests / for later iteration" as excuse for unexecuted items
- 📋 §1 added **Report Format**: forbid Phase A/B/C/D list + "Final Status" + "Not Done (Kept Per Instruction)" three-section format; when user says "do all", no "Not Done/Kept" section allowed
- 🎯 Root cause: counteract Opus 4.7's default "defensive reporting", "clarification follow-ups", and "structured checklist" tendencies compared to 4.6
- 🔄 7-language rule files (STEERING_CONTENT + DEV_WORKFLOW_PROMPT) fully synced with CLAUDE.md v2.4.5 updates
